      Hi people, I hope you can explain to me my problem. I have got two selectOneMenu, I need to do this: when I choose an activity, the task list must be created. But nothing happens.

      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.
