selectManyCheckbox -> hidden fields for some users

[Matt Raible]

I have a requirement to show a group of checkboxes for some users, and 
hide them for others.  When they're hidden, I still want to retain the 
data - so storing them as hidden fields seems the logical thing to do.

I have this for the users that can edit the checkboxes:
       <h:selectManyCheckbox value="#{userForm.userRoles}" id="userRoles">
           <f:selectItems value="#{userForm.availableRoles}"/>
       </h:selectManyCheckbox>
This works great.  For hidden fields, I'm using:
       <f:verbatim>
           <c:forEach var="role" items="${userForm.userRoles}" 
varStatus="status">
               <c:out value="${role}"/><c:if 
test="${!status.last}">,</c:if>
               <input type="hidden" name="userForm:userRoles" 
value="<c:out value="${role}"/>" />
           </c:forEach>
       </f:verbatim>

While this works, I'd rather not have to wrap it with <f:verbatim> (for 
my <h:panelGrid) - is there an easier way to do this?

Thanks,
Matt
