Get selected node of an adf tree in backing class

Question

hi,
i am deploying an adf web application, i use jdeveloper 11g and a weblogic webserver.
i have a bean family this bean contains a list of families and a parrentfamily object, so it is a rekursive relationship.
i use the adf tree component to show all the families starting with the root family. works fine. only had to create a data controle of the bean and with dragndrop i create the adf tree.
now i want to create a subfamily of any family shown in the tree, so i need the selected tree node in my backing bean (in a methode which is the action of my buttono) of the adf page.
but iam unable to get the data.
so my question i searched many times for:
What is the best and easiest way to get the selection of an adf tree in the backing bean of the page?

Hi,
here's how you get the object itself, assuming your model is POJO based. Assuming "tree" is a variable pointing to a RichTree instance
CollectionModel treeModel = (CollectionModel) tree.getValue();
JUCtrlHierBinding treeBinding = (JUCtrlHierBinding) treeModel.getWrappedData();
RowKeySet rks = tree.getSelectedRowKeys();
if(!rks.isEmpty()){
  List firstSet = (List)rks.iterator().next();
JUCtrlHierNodeBinding node = treeBinding.findNodeByKeyPath(firstSet);
  DCDataRow rw = (DCDataRow) node.getRow();
  //get the object
Object entity = rw.getDataProvider();
