I believe that Flex 3/4 has it own classes in actionscript 3 like <mx Alert.Message etc.. Now if I build a Flex 3 application using only MXML and create an external pure AS3 file for the logic of the program will it work? If the AS3 script file is pure AS3(close to Flash AS3) will Flex3 accept the file and process the script without any issues? Or Flex 3/4 will only accept the <mx AS3 classes to run the program without any issues?
Thanks for your time, Fred.
