Selected node in a tree table (via Data Controls and not managed bean)

Question

I am facing some problems in getting the selected row in a tree table.I have used data controls for creating the tree on the page.
I have 3 POJO's,ex; Class AB which has a list of Class CD.And Class CD has a list of class EF. (Used for the tree table)
Now i have a java class, called MyDelegate.java which has a list of AB.I generated data controls off this MyDelegate class and have dropped the ABlist as a tree table (also displaying CD and EF in the tree table).
It displays fine with nodes of AB,CD (child of AB)and EF(child of CD)
The tree table is not bound to any managed bean.
For performing actions on the tree, i create a method - "doSomething() in the delegate class",generate data controls and drop it as a button.
Inside doSomething(), i need acess to the selected node in the tree (it can be a node of type AB or CD or EF).
The problem: I always get access to the node of type AB, and not the child nodes no matter what i click in the tree table.
doSomething(){
DCBindingContainer dcBindingContainer = (DCBindingContainer)ADFUtil.evaluateEL("#{bindings}");
DCIteratorBinding dcTreeIteratorBinding = dcBindingContainer.findIteratorBinding("lstABIterator");
RowSetIterator rowTreeSetIterator = dcTreeIteratorBinding.getRowSetIterator();
DCDataRow rowTree = (DCDataRow)rowTreeSetIterator.getCurrentRow();
if (rowTree.getDataProvider() instanceof AB) {
          //do something
          AB selectedAB = (AB)row.getDataProvider();
} else if (rowTree.getDataProvider() instanceof CD){
          //do something
} else if (rowTree.getDataProvider() instanceof EF) {
          // do something
How do i access the "selected child node of the tree table" here in the delegate class method? Pls help.

Hi Frank,
Thanks for the response. In my case, i dont have a managed bean, so i am slightly unsure how to do it.
There is a mention "Note that another way to access the treeTable component at runtime is to search for it in JavaServer Faces UIViewRoot. This latter option allows you to write more generic code and does not require to create a page dependency to a managed bean"
How do i use this adf view root (without a managed bean) to get hold of the selected row in the tree table. Pls help.
Thanks.
