Cause

This is a known issue with some of the Microsoft templates and master pages. It turns out that we have AjaxPanel control from Telerik that was used in List View and List Form control and they must be enclosed within <form> tag but also WebPartManager must be enclosed within the <form> tag. Please see this forum discussion for details (http://www.telerik.com/community/forums/thread/b311D-ghcda.aspx).

Resolution

To troubleshoot the issue, please look at the master page template and make proper correction.
