You cannot mix FLOW3's GPL license with a commercial license of extJS,
so the license of extJS used with FLOW3 will always be a GPL license.

It still does mean you can create a commercial application and sell it  
to your customers!, But only as GPL not as any other license.
Your client can do whatever he feels with your commercial application,  
sell it to other customers, publish it on a website (modified or not)  
but your client
HAS to give the source aswell to all people he sells it to.

For you there is no other option then to give the source up-on request  
to your customers because FLOW3 is GPL to start off with.


PS 1: I am not a lawyer or anything...
PS 2: a BSD license would have been better under the above situation,  
but FLOW3 wanted to be compatible with TYPO3's license model so  
extensions could be re-used. (correct me if I am wrong here please).
