How to populate Navigation List

Question

Hi
I need to populate a navigation list with values obtained from an RFC.
Can I do this in the same way as populating DDBK?
The DDBK is linked to a Context Value Attribute, but the Navigation List is linked to a Context Node. The context value attribute linked to the DDBK is "addBusUnit". The context node linked to the Navigation List is "TeamList" with value attribute "Member". How would I change the following code(from the DDBK) so that it will work with the Navigation List?
IWDAttributeInfo attinfoBus = wdContext.getNodeInfo().getAttribute("addBusUnit");
ISimpleTypeModifiable modinfoBus = attinfoBus.getModifiableSimpleType();
IModifiableSimpleValueSet valueSet = modinfoBus.getSVServices().getModifiableSimpleValueSet();
try
wdContext.currentZhr_360_Teamviewer_InputElement().modelObject().execute();
     for (int i = 0;     i < wdContext.nodeZteamviewers().size(); i++)
valueSet.put(wdContext.nodeZteamviewers().getZteamviewersElementAt(i).getZzpaycode(),
     wdContext.nodeZteamviewers().getZteamviewersElementAt(i).getZzfullname());
catch (WDDynamicRFCExecuteException d)
     manager.reportException(d.getMessage(), false);
thanks in advance

To populate a NavigationList, bind the "itemSource" property to a context node and bind the other "item*" attributes to attributes inside that node. The item source may be a recursive node.
Say the item source node is named "NavItems" with attributes "FullName" and "PayCode". Then you may use code like
try
  wdContext.currentZhr_360_Teamviewer_InputElement().modelObject().execute();
  wdContext.nodeNavItems().invalidate();
  for (int i = 0; i < wdContext.nodeZteamviewers().size(); i++)
    IZteamviewersElement e = wdContext.nodeZteamviewers().getZteamviewersElementAt(i);
    INavItemsElement navItem = wdContext.nodeNavItems().createNavItemsElement();
    wdContext.nodeNavItems().addElement(navItem);
    navItem.setPayCode(e.getZzpaycode());
    navItem.setFullName(e.getZzfullname());
catch (WDDynamicRFCExecuteException d)
  manager.reportException(d.getMessage(), false);
Bind NavigationList.itemText property to "FullName" to get  the full name displayed as item text.
