Here are the imporant snippets:


<form:select path="fwUser.groups" multiple="true" size="10" cssStyle="width: 275px" >
<form:options items="${command.fwUser.groups}" itemLabel="name" itemValue="id" />
</form:select>



protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception
{
binder.registerCustomEditor(Set.class, "fwUser.groups", new CustomCollectionEditor(Set.class)
{
protected Object convertElement(Object element)
{
if (element != null) {
Long id = new Long((String)element);
Group group = getFwService().findGroupById(id);
return group;
}
return null;
}
});
}

Let me know if you can get it working based on my example. It took me a few days to figure out that little bit of code.

Thanks you TerpInMD for giving quick response. Actually i have fixed this problem for using spring binding. Here is the sample code

Jsp
-----

<spring:bind path="submitForm.division">
<select name="<core:out value="${status.expression}"/>">
<core:forEach items="${divisionMap}" var="divisionCode">
<option
<core:if test="${status.value == divisionCode}">selected</core:if>
value="<core:out value="${divisionCode}"/>">
<core:out value="${divisionCode}"/></option>
</core:forEach>
</select>
</spring:bind>





Controller
----------


protected Map referenceData(HttpServletRequest arg0) throws Exception {
// TODO Auto-generated method stub
List divisionList = new ArrayList();
divisionList.add("1st Id");
divisionList.add("2nd Id");
divisionList.add("3rd Id");
divisionList.add("4th Id");
divisionList.add("5th Id");
divisionList.add("6th Id");
Map referenceData = new HashMap();
referenceData.put("divisionMap", divisionList);
return referenceData;
}



Thanks,
Mike.
