    pages navigation rule throws exception

    Edem Morny Novice

      I have a navigation rule in my pages.xml as follows

      <navigation from-action="#{registrationManager.modifyObject(registration)}">
       <rule if="#{registrationManager.proceed}">
       <redirect view-id="/history/registrationUpdate.xhtml"/>
       </rule>
       </navigation>
      


      However i get the following exception when i call the registrationManager.modifyObject(), whether i use an s:link or h:commandLink.

      The method isProceed exists on the local interface and the bean, returning a boolean, so why a class cast exception trying to cast to String?

      When i remove the evaluation, my method never gets called. Any ideas what's wrong?
