             Summary: TCK: Issue2648IT: IllegalStateException should be thrown if current response has already been committed (During Ajax Request)
                 Key: MYFACES-4500
                 URL: https://issues.apache.org/jira/browse/MYFACES-4500
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 4.0.0-RC2
            Reporter: Volodymyr Siedlecki


Background Issue: [https://github.com/eclipse-ee4j/mojarra/issues/2652]

In a nutshell: if handling an ajax request, we should throw an IllegalStateException during a second redirect (if the one has been committed). 

This is apparent in the MyFaces code below. We just complete the response in the ajax case ("isPartialRequest") without checking if it's been completed already.
