</rich:panel>
</h:form>
</ui:define>
</ui:composition>The problem is that in backing bean the activity attribute never changes its value... activity is a String in planCoAction class, and it has its setActivity and getActivity. getActivity works... setActivity never was invoked when I run the web in debug mode.
Thanks in advance and sorry for my english.
