Here is the portion from the struts configuration:
struts-warranty.xml
itemsList
The ajax action class looks like this:
public class WarrantyAssignmentItemAjaxAction extends BaseAction
{
private List itemsList;
public List getItemsList() {
Return itemsList;
}
// other stuff removed from breavity
}
I always map the root object to the property I want returned for each
AJAX call because I have noticed that JSON complains should it try to
serialize things such as my service objects and so on.
I did notice that because a few objects within the graph have cyclic
redundancy that JSONWriter logged a few messages about that before it
finally puked so I'm not sure if because my object graph has these
circular references if that is creating problems for it or not.
