Jon, that is really interesting and I need to digest the concept a bit more to see if it will help my workflow situation. In my case I kinda need to go the other way though: Flash CS3 > Flex not Flex > Flash CS3
I've got my live project here if anyone is interested in checking it out: http://www.mountainworkshops.org you can see the error if you view a participant gallery and click the email button, and then click tab. I built each one of these "media players" in flash cause it made sense at the time to try and use the Flex component kit for flash and just attach a class for the functionality. There are essentially three different players, one for the slideshow, one for the video player, and one for the audio sync'd slideshows. At this point I'm thinking of just redoing the slideshow and audio slideshow in Flex and just use flash for the library assets. Seems like a huge pain in the ass for something I have 99% working. oh well...
