Proposal

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

• Draft icon show even there is not any thing in input field

What is the root cause of that problem?

• Report.setReportWithDraft(reportID, true) is called but the empty text is saved that leads to the bug "Draft icon show even there is not anything in the input field". But why is empty text saved? It will be shown bellow:
• Currently, we are using the debounce function to save the draft comment:
  

  App/src/pages/home/report/ReportActionCompose/ComposerWithSuggestions.js

  Lines 206 to 210 in 1223e1e

  	if (shouldDebounceSaveComment) {
  	debouncedSaveReportComment(reportID, newComment);
  	} else {
  	Report.saveReportComment(reportID, newComment || '');
  	}

• The debouncedSaveReportComment function is defined as below:

const debouncedSaveReportComment = _.debounce((reportID, comment) => {
    Report.saveReportComment(reportID, comment || '');
}, 1000);

• Because all the reports share the same debounce function above - debouncedSaveReportComment, so when the user opens chat report A and types any message then quickly switches to report B and types any messages, the debouncedSaveReportComment will ignore all the calls made within that 1000ms (contains the call that made in report A). It leads to the empty draft message being saved with report A.

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

• We can create the new debouncedSaveReportComment that is used separately for each chat report and replace the debounce function mentioned in the root cause part by it:

    const saveReportComment = useCallback((reportID, newComment) => {
        Report.saveReportComment(reportID, newComment || '');
    }, []);

    const debounceSaveReportComment = useCallback(
        _.debounce((reportID, newComment) => {
            saveReportComment(reportID, newComment);
        }, 1000),
        [saveReportComment],
    );

What alternative solutions did you explore? (Optional)

Proposal

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

In LHN, a draft icon shows when there is no text in the input field.

What is the root cause of that problem?

The ComposerWithSuggestions component, which is responsible for input text handling, saves a draft of input text with one second debounce:

App/src/pages/home/report/ReportActionCompose/ComposerWithSuggestions.js

Lines 206 to 207 in e2a1343

	if (shouldDebounceSaveComment) {
	debouncedSaveReportComment(reportID, newComment);

App/src/libs/ComposerUtils/debouncedSaveReportComment.js

Lines 9 to 11 in 8000576

	const debouncedSaveReportComment = _.debounce((reportID, comment) => {
	Report.saveReportComment(reportID, comment || '');
	}, 1000);

The problem occurs when a user types in a message in one report chat, switches to another report and enters another message within one second. The new debounced function call happens, and the previous call becomes overridden, but a report menu item in LHN displays that it was edited.

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

Move the debounced comment save function on the component level. So, every report will have it's own instance of that function. We need to do it in ReportActionCompose (parent component) because it has some use cases with canceling the debounce:

// ReportActionCompose.js
const debouncedSaveReportComment = useMemo(function () {
  return _.debounce((reportID, comment) => {
    Report.saveReportComment(reportID, comment || '');
      }, 5000);
   }, []);
    ...
 <ComposerWithSuggestions
   ...
   debouncedSaveReportComment={debouncedSaveReportComment} // new property
 />

Proposal

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

In LHN, a draft icon shows when there is no text in the input field.

What is the root cause of that problem?

App/src/components/LHNOptionsList/OptionRowLHN.js

Line 263 in 09a0118

{optionItem.hasDraftComment && optionItem.isAllowedToComment && (

The draft icon is shown based on hasDraft field of the report:

App/src/libs/SidebarUtils.js

Line 299 in 09a0118

result.hasDraftComment = report.hasDraft;

and immediately set when user type in composer :

App/src/pages/home/report/ReportActionCompose/ComposerWithSuggestions.js

Lines 222 to 224 in 09a0118

	if (commentRef.current.length === 0 && newComment.length !== 0) {
	Report.setReportWithDraft(reportID, true);
	}

When user type in composer and continuously typing without pause within 1 second of the next character input, the draft is not saved for the current opened report, because of the debouncedSaveReportComment in update comment. Until he stop typing for 1 second, the draft will be saved for currently opened report.
If user immediately open other report when typing continuously, the draft is saved for the next report and previously opened report draft will be empty. But the Report.setReportWithDraft(reportID, true); already executed for previous report and draft icon is shown even though the draft is empty.
We need a way to check is there is really a draft for the report in onyx after user leave the report and opens other report.

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

We could check ifReportActionsList.js reportID has been changed, and set hasDraft value based on previousReportID. In this function or making new function insideReportActionsList.js:

App/src/pages/home/report/ReportActionsList.js

Lines 138 to 144 in 09a0118

	if (userActiveSince.current && prevReportID && prevReportID !== report.reportID) {
	userActiveSince.current = null;
	} else {
	userActiveSince.current = DateUtils.getDBTime();
	}
	prevReportID = report.reportID;
	}, [report.reportID]);

We could add check on the draft and set hasDraft value accordingly:

const draftComment = getDraftComment(prevReportID);
Report.setReportWithDraft(prevReportID, draftComment && draftComment.length > 0);

What alternative solutions did you explore? (Optional)

If the expected result is to make the current draft text input persist for the previously opened report when user switching/opening other report while typing, we could use previousReportID method in ReportActionList.js in ComposerWithSuggestion. If the current reportID of ComposerWithSuggestion has been changed, then we call the Report.saveReportComment with previousReportID param and current value of textInput to save the current draft for previousReportID. Then call Report.setReportWithDraft based on the current textInput value, then clear the textInput.

Result:

draft_icon_lhn_d.mp4

@abdulrahuman5196 did you have any feedback for the proposals?

[abdulrahuman5196]

Checking again.

[abdulrahuman5196]

@DylanDylann @needpower @tsa321

Hi folks, thank you for the proposal. But I am unable to fully understand the root cause.

The display of draft icon is dependent on the hasDraft flag.

App/src/libs/SidebarUtils.js

Line 299 in 09a0118

result.hasDraftComment = report.hasDraft;

But that flag is updated via setReportWithDraft function which is not present inside the debounce function. Then why is it getting affected?

[DylanDylann]

@abdulrahuman5196 setReportWithDraft is just set: whether the report has draft or not. (Based on this value, we display the 'edit' icon in the LHN). But the draft content for each report is set in the debounce function debouncedSaveReportComment. For more detail, please check my proposal

[abdulrahuman5196]

@DylanDylann 's proposal here #27362 (comment) looks good and works well.
