Creating Tree using programmed ViewObject

Question

Hi,
I'm currently trying to create a Tree in a JSF page using a programmatic ViewObject, wich means that I don't have any entity objects, only one ViewObject that is recursive through itself using a ViewLink to connect it.
Structure:
ViewObject name: GroupsView
Atributes:
-Name: String; PK
-Owner: String;
ViewLink name: GroupsLink
Connects like this:
-Cardinality: 1 to *
-Source: GroupsView.Name
-Destination: GroupsView.Owner
and then I drag the link to the page and generate a tree from it, using GroupsView(<NameGroupsview>) level rules, but it seem to give me all the levels inside each level to the infinity, so it doesn't seem to verify the content groups inside each other.
is there any problem with the structure I've used?
thanks

Yes thanks, I've already seen that link before and it worked when using an entity based View Object, my problem is when using a programmatic ViewObject, the link doesn't seem to recognize the structure.
this is what I have in the GroupViewImpl.java:
protected ViewRowImpl createRowFromResultSet(Object qc, ResultSet rs) {
// Create and populate a new row
ViewRowImpl r = createNewRowForCollection(qc);
int pos = getFetchPos(qc);
try {
int a = 0;
RoleProfile Group = rowData.get(pos).getRoleProfile();
populateAttributeForRow(r, a++, new Number(pos));
populateAttributeForRow(r, a++, Group.getName());
populateAttributeForRow(r, a++, null);
//populateAttributeForRow(r, 2, Group.getName());
} catch (IMException e) {
e.printStackTrace();
setFetchPos(qc, pos + 1);
return r;
and this is my selectionlistener from the Bean class:
public void groupSelectionListener(SelectionEvent selectionEvent) {
JSFUtils.invokeMethodExpression("#{bindings.GroupsView1.treeModel.makeCurrent}", Object.class, SelectionEvent.class, selectionEvent);
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("setroleNameVar");
operationBinding.execute();
CurrentUser = getSelectedUser();
CurrentGroup = getSelectedGroup();
try {
System.out.println(CurrentGroup.getName());
} catch (IMException e) {
but I still get the entire collection repeated inside each item of the tree, I wasn't suposed
This is irritating me, because I've searched much for this and still nothing
Thanks again
