[jboss-user] [JBoss Seam] - pages navigation rule throws exception

Thursday, 15 February 2007

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?
