Seemes like everything else is generic right now we're only really scoping to collections but, in the future we'll probably want that as an available feature for the others

Is there anyway we could move these tests into their own namespace to then test [SaveAsDraftToExistingCollectionModal.jsx](https://github.com/nasa/mmt/pull/1515/changes#diff-9d3e6c4acbdeb66fdd616092b410439f20e0124b7a0e28f4d59440da971af001) independently?

While the collection search or fetch is loading, this modal cannot be dismissed: the X is hidden, no Cancel action is rendered, and toggleModal(false) is explicitly ignored. If the CMR request stalls rather than returning an error, the user is trapped in the modal and must reload the page. Could we keep Close/Cancel available during loading and either cancel the pending query or ignore its result if it completes after the modal has closed?

Would it be worth adding a focused query for this modal? It only needs nativeId, providerId, and ummMetadata, while GET_COLLECTION requests the full collection and its related resources. A smaller query would reduce unnecessary backend work and would also eliminate the Apollo missing-field warnings from the new tests.

Is the generalized /:type/staged/:id route intended to support additional staged concept types in the future? That makes sense, but the current page and backend remain collection-specific. Should we validate type for now so unsupported staged URLs fail cleanly until those types are implemented?

<excerpt>The `useLazyQuery` hook is for manually executing queries. Unlike `useQuery`, when you use `useLazyQuery`, it doesn&`#39`;t immediately execute its associated query. Instead, it returns an execution function that you call whenever you need to execute the query. ... function GetDogsOnClick() { const [getDogs, { loading, error, data }] = useLazyQuery(GET ... OGS); if (loading) return <p>Loading ...</p>; ... if (error) return `Error ... ${error.message}`; ... return ( <div> ... => ( < ... key={dog.id} dog={dog} /> ))} ... <button onClick={() => ... The first item in `useLazyQuery`&`#39`;s return tuple is the execution function, and the second item is an object that contains information about the executed query, such as the `loading`, `error`, `data`, and `dataState` properties. ... Unlike `useQuery`, options provided to `useLazyQuery` that change on re-renders do not automatically execute the query. Instead, `useLazyQuery` waits to execute the query with the updated options until you call the execution function again. ... ```tsx function GetDogs({ isOnline }) { const [getDogs, { loading, data }] = useLazyQuery(GET_DOGS, { fetchPolicy: isOnline ? "network-only" : "cache-only", }); if (loading) return <p>Loading ...</p>; return ( <div> {data && <Dogs data={data.dogs} />} <button onClick={() => getDogs()}>Get dogs</button> </div> ); } ... The changed options are immediately applied to the underlying `ObservableQuery` (accessible by the `observable` property) even though the query isn&`#39`;t executed. Inspecting the options on the `observable` returns the updated options. This means the updated options are used for other APIs (such as `refetch`), even before you call the execution function again. ... useLazyQuery ... The `variables` property is empty until you call the execution function for the first time. Use the `called` property returned by `useLazyQuery` to determine if you&`#39`;ve called the execution function at least once ... By default, the `useQuery` hook checks the Apollo Client cache to see if all the data you requested is already available. If all of the data is available in the cache, `useQuery` returns that data and doesn&`#39`;t query your GraphQL server. This `cache-first` policy is Apollo Client&`#39`;s default fetch policy. ... You specify a fetch policy using the `fetchPolicy` option. For example, we can instruct `useQuery` to bypass the cache and fetch from the network by setting the `fetchPolicy` option to `network-only`: ... ### `nextFetchPolicy` ... You can also specify a query&`#39`;s `nextFetchPolicy`. When provided, `fetchPolicy` is used for the query&`#39`;s first execution, and `nextFetchPolicy` is used to determine how the query responds to future cache updates: ... ```js const { loading, error, data } = useQuery(GET_DOGS, { fetchPolicy: "network-only", // Used for first execution nextFetchPolicy: "cache-first", // Used for subsequent executions }); ... If you want to apply a single `nextFetchPolicy` by default, because you find yourself manually providing `nextFetchPolicy` for most of your queries, you can configure `defaultOptions.watchQuery.nextFetchPolicy` when creating your `ApolloClient` instance: ...

<location>GitHub pull request 10229 in apollographql/apollo-client (link omitted to avoid creating a cross-reference)</location>
<excerpt>## fix(regression): avoid calling `useQuery` `onCompleted` for cache writes ... There are a few related issues pointing to a regression that occurred between `v3.4.17` and `v3.5.0` and greater: writes to the cache (it doesn&`#39`;t matter how the cache update occurs: directly via `cache.writeQuery`, via a separate `useMutation` call, etc.) trigger the `onCompleted` callback passed to `useQuery`, whereas in `v3.4.x`, `onCompleted` was triggered when the initial network request completed, and not on subsequent cache writes. ... My proposed solution here is to compare the previous and current `result`&`#39`;s loading states: if the loading state doesn&`#39`;t change, `onCompleted` won&`#39`;t re-fire. This approach has the benefit of working as expected with the `notifyOnNetworkStatusChange` option which will cause `onCompleted` to fire after subsequent network requests if `notifyOnNetworkStatusChange` is set to `true`. ... > NB: this change would mean that both direct cache updates to the watched selection set and updates as a result of other network requests (beyond the `useQuery` hook invocation in question) would _never_ cause `onCompleted` to fire. This seems more intuitive to me. ... Calls to `refetch` and queries with `pollInterval` configured work the same way: they don&`#39`;t update the `loading` state unless `notifyOnNetworkStatusChange` is `true`. If we&`#39`;d like to preserve the current behavior whereby polling queries fire `onChange` when watched cache data changes _without updating `loading`/`networkStatus`_, we can keep the condition in https://github.com/apollographql/apollo-client/pull/10229/commits/b521d12f39899d654ac4590b53555f203727022d#diff-fb7fa652de6d84c08b87344a06a4d120b664c6e8bf491d16575794c755141477R517. I&`#39`;m in favor of keeping `onCompleted` execution consistent across the board, but would love input on this. ... There also seems to be some confusion re: polling and `onCompleted`: looking at this issue, the callback is not repeatedly firing because the cache never changes. https://github.com/apollographql/apollo-client/issues/5531 ... alessbell** ... 5531: Using useQuery ... pollInterval triggers onCompleted only once](https://github.com/apollographql/apollo-client/issues/5531 ... · Oct 25 ... 37pm ... **alessbell** mentioned this in issue [`#9688`: The onCompleted callback of the useQuery hook executes on data mutations](https://github.com/apollographql/apollo-client/issues/9688) · Oct 26, 2022 at 6:14pm ... **alessbell** mentioned this in issue [`#10076`: The `onCompleted` callback of `useQuery` executes from cache writes.](https://github.com/apollographql/apollo-client/issues/10076) · Oct 26, 2022 at 6:15pm ... > `@alessbell`: Given that this PR has been merged into v3.8 - is it correct that the intended behaviour of `onCompleted()` is to only be called when a request for the associated query has responded with _different_ data than what&`#39`;s in the cache? If that&`#39`;s the case, would it be possible to also expose another callback like `onResponse()` that gets called whenever a response for a request triggered by the hook is returned, no matter if the data has changed or not? Otherwise there doesn&`#39`;t seem to be any reliable way to react to refetches/polling updates without opting in to having the component also get re-rendered on network status (which can have significant negative performance impact). I&`#39`;d be happy to open up an issue for this if relevant. > > (following up on https://github.com/apollographql/apollo-client/issues/5531#issuecomment-1290736471)</excerpt>

Using that object syntax with `refetchQueries` actually creates an entirely new `ObservableQuery` instance under the hood (the thing returned by `client.watchQuery(...)` which `useQuery` calls under the hood), so these queries weren&`#39`;t actually connected in any meaningful way.

<excerpt>## fix(regression): avoid calling `useQuery` `onCompleted` for cache writes ... There are a few related issues pointing to a regression that occurred between `v3.4.17` and `v3.5.0` and greater: writes to the cache (it doesn&`#39`;t matter how the cache update occurs: directly via `cache.writeQuery`, via a separate `useMutation` call, etc.) trigger the `onCompleted` callback passed to `useQuery`, whereas in `v3.4.x`, `onCompleted` was triggered when the initial network request completed, and not on subsequent cache writes. ... My proposed solution here is to compare the previous and current `result`&`#39`;s loading states: if the loading state doesn&`#39`;t change, `onCompleted` won&`#39`;t re-fire. This approach has the benefit of working as expected with the `notifyOnNetworkStatusChange` option which will cause `onCompleted` to fire after subsequent network requests if `notifyOnNetworkStatusChange` is set to `true`. ... > NB: this change would mean that both direct cache updates to the watched selection set and updates as a result of other network requests (beyond the `useQuery` hook invocation in question) would _never_ cause `onCompleted` to fire. This seems more intuitive to me. ... Calls to `refetch` and queries with `pollInterval` configured work the same way: they don&`#39`;t update the `loading` state unless `notifyOnNetworkStatusChange` is `true`. If we&`#39`;d like to preserve the current behavior whereby polling queries fire `onChange` when watched cache data changes _without updating `loading`/`networkStatus`_, we can keep the condition in https://github.com/apollographql/apollo-client/pull/10229/commits/b521d12f39899d654ac4590b53555f203727022d#diff-fb7fa652de6d84c08b87344a06a4d120b664c6e8bf491d16575794c755141477R517. I&`#39`;m in favor of keeping `onCompleted` execution consistent across the board, but would love input on this. ... There also seems to be some confusion re: polling and `onCompleted`: looking at this issue, the callback is not repeatedly firing because the cache never changes. https://github.com/apollographql/apollo-client/issues/5531 ... alessbell ... 5531: ... onCompleted only once]( ... /apollographql/apollo-client/issues ... 5531 ... Oct 25 ... **alessbell** mentioned this in issue [`#9688`: The onCompleted callback of the useQuery hook executes on data mutations](https://github.com/apollographql/apollo-client/issues/9688) · Oct 26, 2022 at 6:14pm ... **alessbell** mentioned this in issue [`#10076`: The `onCompleted` callback of `useQuery` executes from cache writes.](https://github.com/apollographql/apollo-client/issues/10076) · Oct 26, 2022 at 6:15pm ... > `@alessbell`: Given that this PR has been merged into v3.8 - is it correct that the intended behaviour of `onCompleted()` is to only be called when a request for the associated query has responded with _different_ data than what&`#39`;s in the cache? If that&`#39`;s the case, would it be possible to also expose another callback like `onResponse()` that gets called whenever a response for a request triggered by the hook is returned, no matter if the data has changed or not? Otherwise there doesn&`#39`;t seem to be any reliable way to react to refetches/polling updates without opting in to having the component also get re-rendered on network status (which can have significant negative performance impact). I&`#39`;d be happy to open up an issue for this if relevant. > > (following up on https://github.com/apollographql/apollo-client/issues/5531#issuecomment-1290736471)</excerpt>

<excerpt>A hook for imperatively executing queries in an Apollo application, e.g. in response to user interaction. ... ###### `fetchPolicy`(optional) ... `WatchQueryFetchPolicy` ... Specifies how the query interacts with the Apollo Client cache during execution (for example, whether it checks the cache for results before sending a request to the server). ... For details, see Setting a fetch policy. The default value is `cache-first`. ... ``` [execute: LazyQueryExecFunction<TData, TVariables>, result: QueryResult<TData, TVariables>] ``` ... `execute` ... `(options?: LazyQueryHookOptions) => Promise<LazyQueryResult<TData, TVariables>>` ... Function that can be triggered to execute the query. The `useLazyQuery` function returns a promise that fulfills with a query result when the query succeeds or fails. ... ###### `data`(optional ... An object containing the result of your GraphQL query after it completes. ... - `empty`: No data could be fulfilled from the cache or the result is incomplete. `data` is `undefined`. - `partial`: Some data could be fulfilled from the cache but `data` is incomplete. This is only possible when `returnPartialData` is `true`. - `streaming`: `data` is incomplete as a result of a deferred query and the result is still streaming in. - `complete`: `data` is a fully satisfied query result fulfilled either from the cache or network. ... ###### `called` ... If `true`, the associated lazy query has been executed. ... The instance of Apollo Client that executed the query. Can be useful for manually executing followup queries or writing data to the cache. ... ###### `refetch` ... A function that enables you to re-execute the query, optionally passing in new `variables`. ... To guarantee that the refetch performs a network request, its `fetchPolicy` is set to `network-only` (unless the original query&`#39`;s `fetchPolicy` is `no-cache` or `cache-and-network`, which also guarantee a network request). ... ###### `updateQuery` ...

However, even if the request is correct, the onCompleted callback is called and the load is still in true state and data are undefined. I also tried pure useQuery, but the same result. I tried different settings and combinations of fetchPolicy as notifyOnNetworkStatusChange. But none of them helped. I have tried older versions as well. Nothing.

I need to know when the query is complete whether it used the network or the cache. Here is the basics of the code, which uses `cache-first` network policy ```jsx //manually track loading state const [isLoading, setIsLoading] = useState(false) const [loadQuery, { data, error, loading }] = useLoanListLazyQuery({ onCompleted: data => { //when the query is done, turn off manual loading state setIsLoading(false) }, }) //when the input changes useEffect(() => { //load the data using the query loadQuery({ variables: { queryTrigger } }) //manually turn on loading state setIsLoading(true) }, [queryTrigger]) ``` A working repro of my issue explained below: [https://codesandbox.io/s/apollo-client-beta-fetchmore-bug-forked-k5bip](https://codesandbox.io/s/apollo-client-beta-fetchmore-bug-forked-k5bip) Steps: 1. Onload, Count = 3 ``` loadQuery: 3 loading: false IsLoading: false loading: true IsLoading: true loading: false Completed: 3 - 1631415455914 IsLoading: false ``` 1. Set Count = 5 (repro app trigger onchange, so hit backspace and press &`#39`;5&`#39`;) ``` loadQuery: 5 IsLoading: true loading: true loading: false Completed: 5 - 1631415463170 IsLoading: false ``` 1. Set Count = 3 (same as the original, so getting cached data) ``` loadQuery: 3 IsLoading: true Completed: 3 - 1631415463456 IsLoading: false ``` > a. Note that `loading` is no longer changed when retrieving from the cache. > b. The manual isLoading state is still being set correctly. > c. Everything up until this point is ok. 1. Set Count = 3 (backspace to clear the existing 3, then type 3 again) ``` loadQuery: 3 IsLoading: true ``` > a. Notice the query is called, the data still displays, but the `onCompleted` is never called. > b. This feels like a bug to me. I would expect the same output as Step 3. > c. This sample is using `3.5.0-beta12`. `3.4.11` shows something different...

Handle the lazy-query result promise when reopening the modal.
Both executions use cache-first, and the modal depends on onCompleted to leave searching and loading-target. Apollo can omit onCompleted when useLazyQuery returns the same result for the same variables. Handle the execution promise and process its returned data and error instead. Do not rely on network-only as the fix.
Add a regression test that closes and reopens the modal with the same mocks.

at line 77, Update the getCollection execution flow to handle its returned
promise and process the result’s data or error so the modal exits searching and
loading-target even when onCompleted is skipped for a repeated cache-first
result. Keep cache-first behavior, and add a regression test that closes and

I think we also need to include conceptId and revisionId in this query. GraphQLProvider uses these fields to identify collections in Apollo’s cache. Without them, every target shares the key Collection.

Fixed by adding conceptId and revisionId to the GET_TARGET_COLLECTION query.

Could more than 20 published collections share the same ShortName, across providers or versions? If so, should we paginate this search? We currently only show the first page and ignore collections.count, so the intended collection might not appear in the choices.

Fixed by requesting limit: 2000 on the search and showing a warning banner when collections.count exceeds the number of items actually returned.

Overview
What is the feature?
Add a "Save as Draft to Existing Collection" option to the staged concept preview page, and shows the user what would change before they confirm.
What is the Solution?
SaveAsDraftToExistingCollectionModal, a new modal opened fromStagedConceptPreviewvia a "Save as Draft to Existing Collection" action. It searches CMR for a published collection with a matchingShortName:ShortNameon the staged metadata → shows an error instead of running an unfiltered search.ummMetadataand compares it against the staged metadata:react-codemirror-merge) is shown so the user can review exactly what will change.nativeIdandproviderId.What areas of the application does this impact?
