forceId for x:inputHidden behavior

[Dennis_Byrne]

I've set x:[EMAIL PROTECTED] inside a form.  When the form is submitted, the name of the parameter is "myForm:foo" .  

The docs for forceId say "If true, this component will force the use of the specified id when rendering." I would expect that after specifying forceId="true", the name of the parameter would then be "foo".  I have done this, but the original parameter name is still there.  

What does forceId do?
How do I force the HTTP parameter name to be "foo"?  Are we just supposed to sandwich an _expression_ between two verbatim tags?
