FIX: Hidden field parameters in a Web page may be modified when you record a Web test in Microsoft Visual Studio 2005 Team System Test Edition

When you record a Web test in Microsoft Visual Studio 2005 Team System Test Edition, the hidden field parameters in a Web page that contains JavaScript may be modified. Additionally, the Web Test Recorder may record (bind) the modified hidden field parameters incorrectly.

This problem occurs if the Web page that is recorded contains a post form that has an onClick event handler.

This problem occurs because the Web Test Recorder records incorrect values for the hidden fields or assigns empty value to the hidden fields if the hidden field parameters are modified in JavaScript.
