Thanks Mike.
It's working now after using property editor class.
But still there is one problem.I am not able to populate the list of areas
and webSystemImpacted in the jsp.
In the engagementformform.jsp i am doing like this...
<appfuse:label styleClass="desc" key="engagementform.systems"/>
<spring:bind path="engagementform.systems">
<SELECT name="system">
<c:forEach var="sys" items="${webSystemImpacted}">
<OPTION value='<c:out value="${sys.id}" />'
<c:if test="${engagementform.systems.id==sys.id}">SELECTED</c:if>>
<c:out value="${sys.name}"/> </OPTION>
</c:forEach>
</SELECT>
</spring:bind>
And in onSubmit() method of EngagementformController.java i am doing like...
ModelAndView modelview = new ModelAndView(success);
modelview.addObject("webSystemImpacted",webappssystemManager.getAll());
modelview.addObject("areas",areasimpactedManager.getAll());
return modelview;
When i am calling engagementformform.jsp for editing record the the flow
goes to formBackingObject method of EngagementformController.java not the
onSubmit(),but i am not getting how will i populate
"webSystemImpacted" in formBAckingObject method
