Checkbox Tree partial selection problem

Smart GWT Technical Q&A
1

In Checkbox Tree while getting selected nodes, it return partial selected nodes also.

In following sample code when I click on ‘C1’ node, it partially select its parent node as well which is correct behavior.
But for ‘getSelection’ method it returns ‘C1’ along with its parent.

Here I dont want to get parent node in selection as it is partially selected.

How to get only selected nodes?

    private void showSelected()
    {
    	ListGridRecord rec[] = counterTree.getSelection();
    	for(int i=0; i<rec.length; i++)
    	{
    		rec[i].getAttribute(ST_COUNTER);
    	}
    }
}

Any updates?
Is there any way to identify selected node is partially checked or fully checked?

ListGrid.getSelection(boolean excludePartialSelections) is now in SVN. When excludePartialSelections is true, partially selected records will not be returned. TreeGrid is a subclass of ListGrid so the same method applies.
