Proposal

Please re-state the problem that we are trying to solve in this issue.

In offline, parent conversation is not highlighted.

What is the root cause of that problem?

1. We're not allow navigating to parent within reportID

App/src/components/ParentNavigationSubtitle.tsx

Lines 50 to 52 in 126d92a

	if (isVisibleAction && !isOffline) {
	// Pop the chat report screen before navigating to the linked report action.
	Navigation.goBack(ROUTES.REPORT_WITH_ID.getRoute(parentReportID, parentReportActionID), true);

2. If we remove isOffline. In case users login to the App by deeplink, then go offline, the pages will be empty (has not been loaded yet)

App/src/hooks/usePaginatedReportActions.ts

Line 22 in d5cdd55

const [reportActionPages] = useOnyx(`${ONYXKEYS.COLLECTION.REPORT_ACTIONS_PAGES}${reportIDWithDefault}`);

so the data is empty

App/src/libs/PaginationUtils.ts

Lines 175 to 177 in d5cdd55

	if (pages.length === 0) {
	return {data: id ? [] : sortedItems, hasNextPage: false, hasPreviousPage: false};
	}

that shows the loading screen even though the data is loaded.

What changes do you think we should make in order to solve the problem?

Solution 1: Disable navigating to parent if isOffline and pages is empty

We should update this condition in here and here

But this solution is not a best idea since even the page is not loaded, we still can show the parent message.

Solution 2:

Remove isOffline in 2 these places

Then update getContinuousChain logic to return sortedItems if page is empty

if (pages.length === 0) {
        const item = sortedItems.find((item) => getID(item) === id);
        return {data: id && !item ? [] : sortedItems, hasNextPage: false, hasPreviousPage: false};
    }

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

We should update getContinuousChain test to cover this case

What alternative solutions did you explore? (Optional)

Proposal

Please re-state the problem that we are trying to solve in this issue.

Chat - In offline, parent conversation is not highlighted.

What is the root cause of that problem?

We are not linking to the parent report action id in offline mode here

App/src/components/ParentNavigationSubtitle.tsx

Lines 50 to 52 in 126d92a

	if (isVisibleAction && !isOffline) {
	// Pop the chat report screen before navigating to the linked report action.
	Navigation.goBack(ROUTES.REPORT_WITH_ID.getRoute(parentReportID, parentReportActionID), true);

When comment linking to parent report action was implemented a regression occurred where if you create threads offline and try to comment link back to parent actions it was showing skeleton loading although the report actions where available in onyx so we disabled comment linking to parent actions in here by adding conditions in all three places here here and here
But the reason it was showing loading indicator was because usePaginatedReportActions was returning empty data (reportActions list) because when linking to report actions we return empty if page is empty here

App/src/libs/PaginationUtils.ts

Lines 175 to 176 in 126d92a

	if (pages.length === 0) {
	return {data: id ? [] : sortedItems, hasNextPage: false, hasPreviousPage: false};

What changes do you think we should make in order to solve the problem?

Remove the isOffline checks in all three places here here and here

To avoid the skeleton loading problem we should only return empty if the linked report action doesn't exist in sortedItems list

App/src/libs/PaginationUtils.ts

Lines 175 to 176 in 126d92a

	if (pages.length === 0) {
	return {data: id ? [] : sortedItems, hasNextPage: false, hasPreviousPage: false};

 if (pages.length === 0) {
        return {data: id && !sortedItems.some((action) => getID(action) === id) ? [] : sortedItems, hasNextPage: false, hasPreviousPage: false};
    }

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

We can create a test for getContinuousChain by passing empty pages and proper id param to assert that it doesn't return empty if the action exists in sortedItems

@FitseTLT Your new proposal is same as mine 🙏. You deleted the previous one after reading my proposal.

You just added another place that can be easy to figure out (by searching if (isVisibleAction && !isOffline) in our code). I think we can create the util function to prevent duplicated code.

I reposted after digging into the previous changes to identify the correct problem we were trying to solve with the check and proposed a full solution based on that which includes all places (you are missing) that we need to remove the isOffline check. It has nothing to do with your solution. And suggesting to creat util function doesn't proof that you could easily find the missed case. Let's just wait for the reviewer

@sonialiap Huh... This is 4 days overdue. Who can take care of this?
