Describe the bug / error

I have build several ListView Command Set that interact with selected items on a list. Recently, the new Microsoft Lists design appears to be rolling out on SharePoint lists. After this change, some of our Command Sets stopped working. When I tried it out in development it turns out that event.selectedRows is an empty array, so if you have a ListView Command Set that uses selected items, they no longer work.

I'm talking about the new list experience in SharePoint. The following is no longer working: selecting an item and triggering a Command Set on that item:

This is that part of (boilerplate code) that stopped working:

// event.selectedRows is now an empty array, 
public onExecute(event: IListViewCommandSetExecuteEventParameters): void {
    const listItemId = event.selectedRows[0].getValueByName("ID")
    switch (event.itemId) {
      case 'SOME_COMMAND':
        this.doSomething(listItemId).catch(console.error);
        break;
      default:
        throw new Error('Unknown command');
    }
  }

There is a workaround

I can work around this by accessing the selectedRows through the context object: this.context.listView.selectedRows

Steps to reproduce

1. Use the getting started guide

2. Update the onExecute method from the code section with the following:

   @override
   public onExecute(event: IListViewCommandSetExecuteEventParameters): void {
   switch (event.itemId) {
   case 'COMMAND_1':
     Dialog.alert(`Selected ${event.selectedRows.length} items`);
     break;
   default:
     throw new Error('Unknown command');
   }
   }

3. Serve the command set... and interact with it. It should now trigger a dialog saying you have selected 0 items.

Expected behavior

I'd expect the selectedRows property to work correctly, as it is part of the IListViewCommandSetExecuteEventParameters interface.

Some extra information: The following function has the same issues:

@override
public onListViewUpdated(event: IListViewCommandSetListViewUpdatedParameters): void {
  const compareOneCommand: Command = this.tryGetCommand('COMMAND_1');
  if (compareOneCommand) {
    // This command should be hidden unless exactly one row is selected.
    compareOneCommand.visible = event.selectedRows.length === 1;
  }
}
