Flex-IFrame Comm Test Not Working

Question

I'm trying to get the IFrameCommTest example (from the Flex-IFrame site) to work in Flex 4, and, while the IFrame itself works, the communication does not. In particular, I need to get the included HTML page to call functions from the flex app (I already have a way to get the Flex app to talk to the HTML).

I've exported the project to facilitate your help.

The problem, I suspect, is that the "parent.FABridge" doesn't exist. My guess is that something in flex4 changed with regard to how things are located in the DOM.

(This post is related to the earlier post about FABridge.

I thought this would be a clearer example of the problem. )

Thanks,

Brian
