GWT Cell Tree, Selecting too many options!

I am using a gwt cell tree and I want only one node to be selected in the whole tree but many nodes are being selected.

I am also trying this 

S1= new SelectionModel();......
S1.setSelected(S1.getSelected(),false); but using this technique nothing is being selected.

I am having the following problem:alt text

Can someone help??

You need to provide a key provider to the selection model like this

selectionModel = new SingleSelectionModel<NamedObject>(new ProvidesKey<NamedObject>() {

        @Override
        public Object getKey(NamedObject item) {
            return item.getKey();
        }
    });

This will uniquely identify the nodes in the tree.

Code looks weird to me, because you firstly get selected object with S1.getSelected() command and then kinda re-select same object, so no wonder that nothing happens. Instead S1.getSelected() pass object that you want to select.

Maybe SingleSelectionModel helps you;

SingleSelectionModel selectionModel = new SingleSelectionModel();

See Google Example 2 to SingleSelectionModel usage.
