[xwiki-devs] can jsfx get cleared?

Hello fellow XWikiers, we have a situation where some code must be clearing jsfx somehow. The code that adds to jsfx is there and changing it does output some text. A common code in other pages works flawlessly but does not in a family of pages (Group_*/Discussions) we have. What code can I look for that would be guilty of clearing the jsfx additions? thanks in advance. Paul
