Have you seen this error in your Flex 3 application when tabbing between components using the debug player?
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I had this occurring in one of my apps that had hundreds of files and it took me hours to finally find out that the problem was a stupid little progress animation SWF that I had loaded into the app. The SWF was pretty old and probably compiled before AS3 was available. The error only occurs after an Alert or Popup window is launched and closed.

Try it out for yourself. Make sure you have the debug player installed and then tab between the TextInput’s. Now click Show Alert, then close the alert and try tabbing between the TextInputs again.
So, the solution, DON’T USE OLD AS2 SWFS IN YOUR AS3 APPS!

I’ve gotten this error when loading AS3 swfs that use the Flash components into a Flex app. The fl.managers.FocusManager class, which is causing the error, is part of the Flash component library.
The only solution I found for this issue was to monkey patch the FocusManager class so that it does not attach key event listeners to the stage.

Derek, is this a generic solution? Once that can be submitted to the Flex SDK?
If so, submit it. Who knows, you can get t-shirt out the deal, just like I did.
Cheers,
Doug

Derek. Would you explain how you “monkey patched” the Focus Manager class.

Hi Derek
I’ve been pulling my hair out over this error for days.
How did you manage to monkey patch a Flash class?
Can you post some more details?

Has anyone submitted this bug to Adobe so they can fix it? We are having the same problem with AS3 .swf(s).
Thanks,

Have you tried to debug the display list itself to find exactly what sits there? Check http://play.blog2t.net/finding-the-missing-child/
