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

[reedpamsft]

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

[reedpamsft]

@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?

[wuxiaojun514]

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.

[Haiqi-Wu]

@reedpamsft Will the fix roll out this week?

[Haiqi-Wu]

Looks like it's fixed.

[wuxiaojun514]

Yes, it works for me now.
Many thanks!
I will close this ticket.

@reedpamsft Was anything rolled back recently? I saw this was working fine yesterday and today it appears to be behaving how it did before

[reedpamsft]

@Feets20 unfortunately, the fix for this issue caused #10074 . We pushed a configuration change to turn off this fix, and Natalie's working on redoing this fix so that it doesn't also break that scenario.

[Haiqi-Wu]

@reedpamsft When will the new fix roll out?

[reedpamsft]

@Haiqi-Wu no ETA to share yet, sorry.

[vlad-nvs]

Hi.

This issue is still reproducible at the end of March 2025!
Any news about a fix?

[natalieethell]

Thanks for your patience here, sorry for the delay! We had two attempted fixes for this grouped view bug, but had to roll back because it seemed to cause some other issues. I'm looking into a new fix and will post updates here.

[PKOITC]

We have the same problem. Can we reopen the issue if it's not fixed ? Are there any known work-arounds ?

[wuxiaojun514]

@PKOITC I reopened it. Currently my work around is to avoid using group by in the view.

@natalieethell
Is there any progress on this?

This current behavior can be quite confusing. For example, when we have a group with two files and the used selects the files one by one. The first select triggers the event, but the second selects the whole group and doesn't trigger the event.
So our extension sees only a single file selected, while the user selected multiple.

[natalieethell]

There was a change rolled out recently that should fix this issue. @RoelVB @wuxiaojun514 can you confirm?

[wuxiaojun514]

Hi @natalieethell
It looks fine now, thanks for the hotfix, I will close it
