[Keith Naas (JIRA)]

javascript error in IE6 when remote call does not render anything to response.
------------------------------------------------------------------------------

                 Key: JBSEAM-1324
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1324
             Project: JBoss Seam
          Issue Type: Bug
          Components: Remoting
            Reporter: Keith Naas
         Assigned To: Shane Bryzak


If an exception occurs in the remote call, it is caught by the ExecutionHandler, logged, and the request is ended.  Since nothing is written to the response, the document is empty.  In IE6 this causes a javascript error.

Something like this should get rid of the problem.
