Do you just want to set selectable=false on the List in certain situations?

That does work, though the new item is still highlighted first, so I might be better of using "change", thus covering keyboard selection as well. I saw a Gumbo example on flexexamples using a selectionChanging event, so it seems as though this use case will be supported in future.

I have some application-wide strategies in mind, and I have also seen how I can prevent tab switching in a tab navigator by registering a capture-phase click listener and calling stopImmediatePropagation and preventDefault. But the same strategy didn't work on a DataGrid, where the grid selection is used as a form of navigation: <mx:DataGrid id="roleList" creationComplete="onGridCreationComplete(event)" private function onGridCreationComplete(event:Event):void { myGrid.addEventListener(MouseEvent.CLICK, onClickGrid, true, 10); } private function onClickGrid(event:Event):void { // alert goes here event.stopImmediatePropagation(); event.preventDefault(); } As a workaround I could handle the change event and restore the previous selection but it would be better to conditionally suppress the selection. I've seen the post on Alex's blog, but am hoping for something listener-based. Thanks.
