Describe the bug / error

I guess this issue maybe related with #9944

We have a spfx list command set with a customized button
Like this screenshot

This week we suddenly find it doesn't work (button doesn't show) in grouped list view when there is only one item in this group

For example, if there is only one pending item in "Approve/Reject" view, then our customized button will never appear.

I debugged the code and find _onListViewStateChanged event will never trigger if there is only one row in group on grouped list view.

I saw there is closed similar issue #7794 but that one is not for new list UI.

Steps to reproduce

1. Create a list view commandset extension as https://learn.microsoft.com/en-us/sharepoint/dev/spfx/extensions/get-started/building-simple-cmdset-with-dialog-api said (why this sample page still use the deprecated public onListViewUpdated(event: IListViewCommandSetListViewUpdatedParameters): void method as example?)
2. Run this spfx extension on a list which has grouped list view (You can just enable approval on this list, then you will get "approve/reject items" view which group by approval status
3. You will find that the "Command One" button will never appear if you have only item in the group

Expected behavior

The _onListViewStateChanged event in List View CommandSet Extension should work as expected in grouped list view

We're seeing issues with this as well. This seemed to be fixed / working for a while and then noticed this week it stopped working

@reedpamsft something on the list experiences with SPFx

@VesaJuvonen @wuxiaojun514 @Feets20 thanks! Feets20 reported this on the other thread and we're looking into it.

@VesaJuvonen @wuxiaojun514 @Feets20 we have a fix for this which will roll out with new client builds in January; eta the week of the 13th. Emphasis on "estimated", though. The first build of a new year is often delayed.

I'm facing a similar issue, with a slight difference that when I go to the list page, expand the group, and check the item for the first time it doesn't trigger the listViewStateChangedEvent, this is the first case; in the second case, when I go to the page, expand the group, and check all the items under the group through the multi-checkboxes in the group it doesn't trigger the listViewStateChangedEvent.

And we use SharePoint Online, which is operated by 21v. Will the roll out fix the issue I'm facing?

Hi @Haiqi-Wu ,
I have the same experience for the first case you found, it won't trigger the event in grouped by view until you choose item again.
I remembered this behavior occurs long time ago.
