[jira] Closed: (TAPESTRY-744) page method pageBeginRender() was been invoked twice when direct link to a page
[ http://issues.apache.org/jira/browse/TAPESTRY-744?page=all ]
Howard M. Lewis Ship closed TAPESTRY-744:
-----------------------------------------
Resolution: Invalid
Assign To: Howard M. Lewis Ship
This is correct behavior; pageBeginRender() is invoked when a form within a page rewinds, then again when the response page is rendered.
