Dear all, I encountered into these exception: anonymous wrote : Caused by java.lang.IllegalArgumentException with message: "value of context variable is not an instance of the component bound to the context variable: productRecomForm" But sadly I can not understand the message to solve the problem. Could anyone explain why does this exception is thrown? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124981#...
