In my previous post to this list, I included a link to my Adobe forum post which includes a simple program that reproduces the error. For your convenience, here's a direct link to the post in that thread that contains the code: http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=60&catid=585&threadid=1366770&enterthread=y#4977869
I haven't found any facility for attaching a file to a posting to this list, so I think going to that link is the best way to get the code to you. You'll just need to copy/paste that code into an MXML file and compile. Running it will demonstrate the erroneous behavior, and if you remove the line near the bottom of the script (commented so as to be obvious which one), the behavior will be as expected.
