[jboss-user] [JBoss Seam] - Re: Can I forace a method to be invoked everytime a page is

[c_eric_ray]

Page Event appears to be what I need. However, I get the following exception.

javax.faces.el.EvaluationException: Exception while invoking expression #{elements.init}

here's the pages.xml

  | <pages>
  |     <page view-id="/extract/remittance.xhtml" action="#{elements.init}"/>
  | </pages>

The seam ojbect in question hasn't been created yet and it looks like that's the problem. Is there something else I should do?

Thanks.
