e.g.,

when i select ObjectA in main table then all the collection Objects of ObjectBs shows in separate table. Plz help me how to handle this case ??

hi,
You can create two value nodes for storing these collections. The first one would be singleton node as it is the main list. Under that create the second node with singleton = false.
e.g.
---NodeA
    --attrA1
    --attrA2
    --NodeB(singleton = false)
            --attrB1
            --attrB2
Now populate collection of object A in NodeA and after adding element in NodeA populate respective elements in NodeB.
IPrivate<View>View.INodeANode nodeA = wdContext.NodeAnode();
for (Iterator  it = collectionA.iterator(); it.hasNext(); )
     ObjectA objA= it.next();
     IPrivate<View>View.INodeAElement nodeAElem= nodeA.createNodeAElement();
     wdCopyservice.copy Corresponding(objA,nodeAElem);
     nodeA.addElement(nodeAElem);
     Collection collectioB =objA.getCollectionB();
     for (Iterator  it1 = collectionB.iterator(); it1.hasNext(); )
         ObjectB objB= it1.next();
        IPrivate<View>View.INodeBNode nodeB = nodeAElem.nodeBnode();
        IPrivate<View>View.INodeAElement nodeBElem= nodeB.createNodeBElement();
        wdCopyservice.copy Corresponding(objB,nodeBElem);
        nodeB.addElement(nodeBElem);
Bind NodeA to the first table and NodeB to second one.
After that when you select record in first table automatically its corresponding records will be populated in second table.
Hope this helps!
