Calling Componenet UI from Parent Model in FCE

Hi,

We are currently building models using FCE Engine in R12.

We had a requirement of calling child component(Component) from a BOM Model and display few attributes under component based on selectio of attributes made on parent model.

In OCE we have created a extension by make use of the below CIO objects.Can you  help with substituted objects names in FCE  for the below objects in OCE.

import oracle.apps.cz.cio.IUserInterface;

import oracle.apps.cz.cio.IUserInterfaceNode;

It will be great if you can throw some light on acheiving this functionality in FCE through any alternate approach.
