Hi, I've just noticed an answer for this thread and I'm curious how do you perceive this problem in general. http://www.jboss.com/index.html?module=bb&op=viewtopic&t=112124 ...suggesting cleaning browser cache as a solution for a specific error. Ok, as a developer I can do it after A4J update that requires it. But after going into production environment and when in the future there will be a need for such update after a huge amount of users got it cached...? Don't you feel scared by this? Suggesting reload in this situation can be often a no-go (uneducated users, perceived system credibility etc.). Another question is how to make user to reload his cache (special error page for ResourceNotFoundException, suggesting cache reload?). Is there something I'm not aware of?
