I add a SQL Report Viewer Module on a page. It do display report and data perfectly but when I click on edit button to edit page from Persona Bar, it displays UpdataPanel Error which is:

"Cannot Register UpdatePanel with ID 'DocMap' since it was not registered with the Script Manager. This might occur if the update panel was removed from the control tree and later added again, which is not supported. Parameter name: updatePanel".

Now, I am really not sure why this is happening maybe some issue in core files or in Jquery files. I really appreciate you if you help me out.
