How to instantiate BPMObject associate to a group attribute?

Question

In my project exists a BPM Object called Person, this BPM Object has an attribute of type "group" and this group is associated a BPM Object called ItemList.
I'm trying instantiate this object but without success, i'm trying this with the code below:
Person person = new Person();
int i=0;
for (String values : StringList) { 
   person.value = values;
i++
When I run the code, the error below is returned:
The task could not be successfully executed. Reason: 'javax.servlet.ServletException: The task could not be successfully executed. Reason: 'java.lang.RuntimeException: fuego.xobject.runtime.InvalidXOAttributeException: The task could not be successfully executed. Reason: 'fuego.xobject.runtime.InvalidXOAttributeException: BPM Object 'xobject.TSObjects.TSApproveExchange$GrpExchange' attribute 'itemList' was not initialized. BPM Object attributes that are not of native types need an explicit mandatory initialization. The initialization of this attribute can be done in the BPM Object constructor.'.'.'. If i'm trying instantiate this Object with the code +person[i] = new Person.ItemList();+ the ALBPM mark the line with error.
How to instantiate a BPMObject of the "group" type?

Hi,
Know how you feel. This one bites all us every once in a while.
Expand your BPM Object's Group by clicking the "+" sign beside it. Double click the constructor method for the Group (not the BPM Object's constructor). If the name of the Group's attribute is called "itemList" and if this is an object of the type "ItemList", then add this one line of logic:
  ItemList itemList = new ItemList(); Know you know this, but here's one way to populate your "itemList" items in the group from a method in the BPM Object:
for (int i = 0; i <= 4; i++) {
    Integration.ItemList newItem = ItemList();
    newItem.city = "Dallas";
    newItem.number = ((String) i);
    this.group.extend(itemList : newItem);
}Hope this helps,
