Hi, Cocomo team. At the same time I've been working with the Cocomo SDK, I've also been experimenting with the Flex 4 SDK/Gumbo. A logical intersection of the two would be in leveraging FXG as the format for the whiteboard application in Cocomo. This would provide a very simple way to serialize/save the whiteboard state in an easily consumable way. The elements currently supported in the whiteboard can all be reproduced/rendered in their FXG analog quite easily.
I'll poke around in the code and see what I can come up with...I don't think there's such a thing as an FXG "parser" yet (even in Gumbo, other than in the compiler) so I might have to create something to read in arbitrary FXG and add it to the UI model/render it dynamically. Might be useful for Gumbo also.
