Drag and Drop of child Components


I have a problem with the z-order of drag and drop Components.

AbsoluteLayout layout = new AbsoluteLayout();
AbsoluteLayout testPane = new AbsoluteLayout();
layout.addComponent(testPane, “left:100px; top:100px;”);
Button bt = new Button();
testPane.addComponent(bt, “left:10px; top:10px;”);

Each of this 3 Components are wrapped by DragAndDropWrapper and could be dragged and dropped.
But the Button “bt” for example could never be dragged or dropped alone because always “layout” is the first drag or drop target.
If I drag the Button, the whole AbsoluteLayout is dragged. How can I change this? I want to allow the User to drag the Button on tes

t pane.
