Setting the value of a hidden field in a form

[Anonymous]

I am getting an exception while setting the value of a hidden field inside a form

Exception: com.meterware.httpunit.MissingParameterValueException:

Does any one know if this behaviour is supported by HttpUnit ?

Thanks,
Karthik

Some info about hidden fieldes hidden it in the release notes:-) . Maybe it should go to the FAQ?

Notes:
    1. Hidden fields may not be modified through the setParameter call if parameter validation is enabled, since they
       cannot be modified through normal user interaction (in the absence of JavaScript). The getScriptableObject call
       provides a way around this.

And also from the release notes, the solution:

3. It is now possible to set the value of a hidden field in a form using a mechanism which will support scripting
              in the future: form.getScriptableObject().setParameterValue( fieldName, newValue )
