JList Drag and Drop issues

Question

I am having a weird problem. I have a JList, and it has draggable elements in it. When i click and drag a selected item it drags jsut fine and DnD suceeds. when i try to drag an unselected item it fails, though the selection changes.
is there any way to change the selection and start draging with jsut hte one click?
thanks
