    Login redirection problem

    fredatwork Newbie

      Hello,

      I have a problem following instructions given by the Seam Reference (13.4.6) for login redirection. As proposed by the documentation, I'd like to send users back where they came from once they've logged in.

      I added the following lines to my components.xml file :

      <event type="org.jboss.seam.notLoggedIn">
       <action expression="#{redirect.captureCurrentView}"/>
       </event>
       <event type="org.jboss.seam.postAuthenticate">
       <action expression="#{redirect.returnToCapturedView}"/>
       </event>


      But I fail to deploy my app since the components.xml file fails to be read because of an java.lang.IllegalArgumentException: must specify expression for declaration exception :

      java.lang.RuntimeException: error while reading /WEB-INF/components.xml

          This was a bug in the docs (already fixed in CVS)
