Misuse of checkboxlist, adding its interceptor removes the message.

> Hello,
> There is another spurious "Unexpected Exception caught setting" message that comes from the use of the checkboxlist tag as it renders its hidden field with the id beginning with "__multiselect_".
> com.opensymphony.xwork2.interceptor.ParametersInterceptor line starting 314
> {code:java}
> for (Map.Entry<String, Object> entry : acceptableParameters.entrySet()) {
>             String name = entry.getKey();
>             Object value = entry.getValue();
>             try {
>                 newStack.setParameter(name, value);
>             } catch (RuntimeException e) {
>                 if (devMode) {
>                     String developerNotification = LocalizedTextUtil.findText(ParametersInterceptor.class, "devmode.notification", ActionContext.getContext().getLocale(), "Developer Notification:\n{0}", new Object[]{
>                              "Unexpected Exception caught setting '" + name + "' on '" + action.getClass() + ": " + e.getMessage()
>                     });
>                     LOG.error(developerNotification);
>                     if (action instanceof ValidationAware) {
>                         ((ValidationAware) action).addActionMessage(developerNotification);
>                     }
>                 }
>             }
>         }
> {code}
> It may be the way I am using the checkboxlist (list of checkboxes in a table), but if I add to the id & name attributes the "cnt" number on the checkboxlist tag to match the id on the checkbox tag the error message goes away?
> ie add   + "-" + Integer.toString(cnt)    below:
> CheckboxListHandler (on the javatempaltes tag!)
> {code:java}
> //Hidden input section
> a = new Attributes();
> a.add("type", "hidden")
>     .add("id", "__multiselect_" + StringUtils.defaultString(StringEscapeUtils.escapeHtml4(id))+ "-" + Integer.toString(cnt))
>     .add("name", "__multiselect_" + StringUtils.defaultString(StringEscapeUtils.escapeHtml4(name))+ "-" + Integer.toString(cnt))
>     .add("value", "")
>     .addIfTrue("disabled", disabled);
> start("input", a);
> end("input");
> {code}
> output code:
> {code:html}
> <input id="favourites_idEmails-1" type="checkbox" value="test" name="idEmails">
> <input id="__multiselect_favourites_idEmails-1" type="hidden" value="" name="__multiselect_idEmails-1">
> {code}
> ####
> The freemarket template may also need the modification to the hidden field, ie add -$\{itemCount\} to the id/name
> {code:html}
> <input type="hidden" id="__multiselect_${parameters.id?html}-${itemCount}" 
>     name="__multiselect_${parameters.name?html}-${itemCount}"
>     value=""<#rt/>
> {code}
> Cheers Greg
