Drag Drop problem : Tree and Absolute Layout


I am developing a drag drop betweeb a tree and an absolute layout. The tree is outside of the absolute layout.
When droppoing a node on the layout, I need to dtermine its relative posistion.
Vaadin book mentions about the WrapperTransferable, however, I get a classcast exception for TreeTransferable to WrapperTransferable.

What am I doing wrong? Is there a differnt way to achieve this functionality.
