Yeah, as you date your releases, (and not mark version's) I did think that I was
using the fixed version.

As I state at the beginning of the previous message 'using new package:'

what I should have said is now using: gwt-dragdrop-2007-04-19.jar

Then I state the updated error message which is different from the previous one.

If there is a version marking I can't find it.  

I am downloading plugin so I can grab source via svn but My current connnection 
is
slow so it'll take a while.

This time I also am adding the file so you can tell me If I've done something 
really
 stupid in the code, but it does work if I make really small moves, as soon as I move
the mouse too much it seems to blow up....

actually I think that behavoiur has gotten worse, I'll try reverting to see if I
introduced an error

[GoogleCodeExporter]

yeah, I can't drag anything now and get error every time, reverting does make 
the
problem revert to previous behavoiur tried both :

DragController dragController = new PickupDragController(boundaryPanel, true);
DragController dragController = new PickupDragController(boundaryPanel, false);

Recently IndexedDropController got a spin-off class IndexedFlowDropController, 
so that:
   DropController dropController1 = new IndexedDropController(mainPanel);
will need to be changed to:
   DropController dropController1 = new FlowPanelDropController(mainPanel);

Updated to r201 with a minor fix to prevent a secondary exception which was 
obscuring
the underlying exception of IndexedDropController now being the wrong class for 
a
IndexedFlowPanel.

r202 adds IllegalArgumentException in the constructor so that this problem is 
caught
right-away, instead of later during drag-and-drop. That should make life a lot 
easier.

Also sprinkled in some @see tags to help out with discovery of the new drop 
controller
