I am moving a sql server reporting services report viewer to v6 and i am getting a nasty error that looks to be caused by the script manager and the way postback is working.

The report viewer control is encapsulated in a user control which also has the script manager and i am calling the usercontrol from a macro and this is called from my razor view.

I would just remove the script manager but I cant as the report viewer requires it as it has ajax functions for loading the report filters etc.

Here is the error and does anyone know a way i can stop this happening or a way around it?  Is it possible to have a standard master page when using Views? This might get around the issue as it all worked fine in v4.

Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
