We are building a presentation software where the slides are realized as either Flash SWF files or Flex modules (also SWF files but with different structure). I need to show a thumbnail preview of the slide upon loading and it works fine for Flash SWF files: I get the DisplayObject from SWFLoader(event.target).content and pass it to our saveThumbnail() routine.
Flex slides, however, seem to resist every attempt to be "screenshotted". I seem to be getting the right object with DisplayObject(event.module.factory.create()) within the READY event handler but when I pass that object to our saveThumbnail() routine, only a white rectangle is stored (the rectangle has the correct size, though!). Any ideas what else I need to do? I've tried to add CREATION_COMPLETE event handler but it is never triggered. I am kind of lost. Any help would be greatly appreciated, Borek
