[Webtest] setting values of hidden fields

[Darrin Wortlehock]

Why can't I set the value of a hidden input?

<setinputfield stepid="set hidden useracl field" name="useracl"
value="Whatever"/>
I need to do this to emulate what an onSubmit javascript handler does.

This is what happens:

Error encountered: create
user(com.canoo.webtest.engine.ConfigurableTestCase): Parameter 'useracl'
must have the value ''. Attempted to set it to: { SiteGod }Exception raised:
com.meterware.httpunit.MissingParameterValueException:

Any ideas?
