Generic Gantt chart - Date field cannot be edited

[cschmidt-1981]

I use the Generic Gantt chart for a project list. Unfortunately, the date field can no longer be changed via the pencil!

In the grid view the corresponding date field can be changed normally.

This error occurs suddenly without any changes to the column formatting or the calculated column.
It remains to be mentioned that the list is used by people who use different date formats.
The date format used by SAMPLE is MM-DD-YYYY

Thanks for your help/ideas on the issue.

Hi @cschmidt-1981 !

Is the phenomenon that you are experiencing like the following video, where you can't click and edit?

If so, perhaps it is due to an update to Microsoft Lists, a similar issue was created and reported in the sp-dev-docs repository.
SharePoint/sp-dev-docs#9614

Unfortunately, I am not aware of a way to address this issue at this time...😢 (If it is a fundamental bug in Microsoft Lists, I suspect we will not be able to address it.)

Depending on the deployment status of the function, this problem may or may not occur.

In the case of the older? Microsoft Lists (no icon next to the column name and the view name is displayed in the command bar), the date can be updated without any problems.

In the case of the newer? Microsoft Lists (with icons next to column names and no view name in the command bar), it seems that the date cannot be updated, as shown in the video in the one previous comment.

I'm seeing the exact same behavior. This seems to primarily (or at least most seriously) effect date fields using inline editing.

• You can click an already populated field, type in an update, and it will save. This seems to be the only case where it's still functional.
• The calendar pop-up is no longer available
• Clicking a blank date field and not updating will enter and save todays date when clicking out of the field
• Clicking a populated field, not updating anything, and clicking away will leave the text box on your screen.
• Once this happens, no drop-down menu (view list, right-click menu, etc...) will function. They flash briefly and dissappear.
• Doing the above 3 times will hang the browser tab as soon as you click any other interactive element on the page

UPDATE: The issue seems to be fixed on our Tenant. Even better, we're now seeing the new modern calendar drop-down when clicking the dates instead of the classic which is a nice bonus as it saves users a click.

Thanks for letting me know @Emmortal451 ! The new modern calendar was displayed in my environment as well!

However, inlineEdit on a custom card still seems buggy. The modern calendar shows up, but it is displayed in the upper left corner and I could not select a date for the calendar😅

I have now checked, and although the UI was broken, the date could still be edited. Therefore, I will close this issue.
