Error on Design Checker

Hi All,

I am getting the following error when I click on the Design checker of a browser enabled form with code:

An error occured while verifying the form template

The SOAP response indicates that an error occurred on the server:

Server was unable to process request. ---> Type 'Microsoft.Office.InfoPath.Server.XPath.ParsedXPath' in assembly 'Microsoft.Office.InfoPath.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' is not marked as serializable.

Any idea what this error is all about?

Any help would be appreciated.

Thank You
