             Summary: a4j:ajax and r:ajax conflict
                 Key: RF-13570
                 URL: https://issues.jboss.org/browse/RF-13570
             Project: RichFaces
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
    Affects Versions: 4.5.0.Alpha2
            Reporter: Ken H


Using both a4j:ajax and r:ajax tags results in a cast exception:

{code}
Exception logged: org.richfaces.view.facelets.html.AttachQueueStack cannot be cast to org.richfaces.ui.ajax.queue.AttachQueueStack: java.lang.ClassCastException: org.richfaces.view.facelets.html.AttachQueueStack cannot be cast to org.richfaces.ui.ajax.queue.AttachQueueStack

{code}

Changing all a4j:ajax tags to r:ajax resolves this but defeats the compatibility goal of having the dual namespaces.
