Patch applied to CVS, thanks.   
   
Sorry, but I don't think that'll ever work in Zope. You can 
make it work by forcing the form to be a GET form, but by the 
time the form contents get to ZRoundup in a POST, the ':foo'   
parameters are swallowed whole by Zope's ':type' argument   
magic handling.
