I am having the exact same error message as in this thread. However, I'm doing absolutely nothing with layouts or itemrenderers at that point. I have an arraycollection as a dataprovider for a dropDownList and when I allow the user to delete the last item, it throws the error but only in the base framework class. http://forums.adobe.com/message/3037403. Has anyone run into this before and found a solution.
Try it in the Hero pre-release. Should be fixed there.
Thanks much. However, I'm on a 64-bit machine. I assume hero still is only available on 32-bit?
Oh, that's just the sdk. OK, I'll give it a try.
Worked great. Thanks a lot.
