Let's start from the really basic; I created a flex app that uses google maps. When embedding the .swf file into an HTML I get nothing on the screen- its missing its dependencies. I copied all the generated files to the same relative locations on the server and still no luck.
My question could be: how to 'wrap' all the dependencies in one file?
In your Project properties - Flex Build Path - Library Pat, select your external SWCs and on Linkage type choose Merge Into Code.
