             Summary: Spurious "Unexpected Exception caught setting" message from com.opensymphony.xwork2.interceptor.ParametersInterceptor
on checkboxlist tags
                 Key: WW-3939
                 URL: https://issues.apache.org/jira/browse/WW-3939
             Project: Struts 2
          Issue Type: Bug
          Components: Plugin - Java Templates
    Affects Versions: 2.3.7
         Environment: Centos/Apache/Tomcat
            Reporter: Greg Huber
            Priority: Trivial


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 select 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:

<input id="favourites_idEmails-1" type="checkbox" value="test" name="idEmails">
<input id="__multiselect_favourites_idEmails-1" type="hidden" value="" name="__multiselect_idEmails-1">

####

The freemarket template may also need the modification to the hidden field, ie add -${itemCount}
to the id/name

<input type="hidden" id="__multiselect_${parameters.id?html}-${itemCount}" name="__multiselect_${parameters.name?html}-${itemCount}"
       value=""<#rt/>


Cheers Greg
