getting an error from Httprequest on ajax.
basically, when I look at firebug I get
<pre>java.lang.IllegalStateException: Class returned from
AsyncResponse.getPartialTraversalViewRoot
must be a UIComponent
com.sun.faces.extensions.avatar.lifecycle.PartialTraversalLifecycle.render(PartialTraversalLifecycle
.java:132)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:245)
</pre></p><p>note <u>The full stack trace of the root cause is available in
the Apache Tomcat
I will forward on details on error in tomcat however, the request actually
does get sent to the server, its the response that is in error.
Any ideas. ????
( really need this working, deadline approxing )
