Not sure why the problem disappeared, but my original question is still valid, however you're right I should have been looking at the collection change handler. It seems that ComboBase.collectionChangeHandler() is kinda wonky :) It does a bunch of things including some conditional invalidateDisplaylist() calls, then calls invalidateDisplayList() anyway, and for REFRESH and some REMOVEs will also dispatch "valueCommit". It won't do anything except invalidateDisplayList() if its an ADD event, which is what we're interested in at the moment, as it's a long-lived list that's late-populated (don't ask, not my arch).
Does invalidateDisplayList() automatically include invalidateSize()? I didn't think it did, but I could be mistaken. If not, is there a reason invalidateSize() isn't called from ComboBase.collectionChangeHandler()? -Josh On Tue, Aug 19, 2008 at 2:53 PM, Josh McDonald <[EMAIL PROTECTED]> wrote: > No doubt.
