I've been trying to get up to speed on Adobe Flex for my CS Capstone project. I should mention, by some surprisingly enlightened decision, Adobe offers a free Flex license to students.

Everything was going great until I it suddenly stopped building the foo.html and foo-debug.html files that launch the foo.swf and foo-debug.swf files. Apparently other people ran into this too. I didn't figure out the proper fix for this but I developed a workaround based on a blog post by one of the Flex developers.

Basically, just rename the index.template.html to ${swf}.template.html and then do a clean rebuild. You should end up with bar.html and foo-test.html and be able to get back to work.
