      Hi all,
      I've got a big problem, whats is happening
      my application got an error like above and after that the page become inacessible, all access to it throws the same error or errors of kind 'not getter method for property abc' even when is all alright, without nullpointers.
      the only way i found to fix it is deleting .class of the page of the work folder of jboss.
      i'm using Jboss 4.0.1 sp1, ejb, struts.
      Why i could fix it?
