I swear I've answered this before, but the search may not be finding it. In any
case, there's a workaround for this. Add this to your form tag:
<do:query-rules><!-- keep the query_rules hash out of hidden-fields -->
<% param_name_for_this %>
</do>
There's a side-effect of calling param_name_for_this that basically tells Hobo,
"I've used this field on the form".
