What version of Hobo and Rails are you using?
One of the first lines in the check-many definitions is this:
<input type="hidden" name="#{param_name}[]" value=""/><% # ensure
all items are removed when nothing checked %>
Can you check to see if this line is appearing in your form and/or
makes it into the request data?
thanks,
Bryan
