Contact me to get the source code, where the compiler throws an error while compiling. I am afraid, it is a huge project. I am sorry, I cannot point you to the exact problem. I tried to figure out, what source code exactly causes the problem, but I couldn't. It compile in Flex2, but it won't with Flex3xxx (or AIR SDK), even with the latest built.
Actual Results:
Throws an error:
(fcsh) fcsh: Assigned 1 as the compile target id
Loading configuration file /Developer/SDKs/flex_sdk_3_engdrop_011408/frameworks/air-config.xml
Error: flash.swf.tags.GenericTag
(fcsh) java.lang.ClassCastException: flash.swf.tags.GenericTag

Expected Results:
Project should compile without any errors.
Workaround (if any):
None
I hope it will be fixed soon -- otherwise it is impossible to use assets which are comming in an SWC.
