Major Description
I have a request to change the design of the popup window ActionForward handling to forward to a framework JSP (or Servlet) instead of writing directly to the response in the DefaultActionForwardHandler. Currently, when the DefaultActionForwardHandler.processForward() routine gets the "_auto" Forward of the return to page flow, we write directly to the response (just with our own javascript, no other markup) and return null. This is a perfectly legal and valid design. However, a design change is needed to support framework implementations (portal) that have a sort of two phase process of first running the action, then including the rendering of return URI from the ActionForward.
The change would be that the DefaultActionForwardHandler.processForward() would no longer write any markup to the response. Instead it would return an ActionForward with a path to a JSP or servlet that would handle the actual rendering.
