[news.eclipse.tools.gef] Blocked ChangeBoundRequests when dragged figure

[benedict heal <bh@xxxxxxxxxxxxxxxx>]

I've modified the demo schema editor into a basic box&line editor.
I want to allow a box to be dragged onto another, though there is no 
semantics of 'adding' attached - the boxes should simply overlap.

This works fine, until the dragging mouse location comes into the figure 
area of another box. At this point I stop getting ChangeBoundRequests, 
and instead get GroupRequests via getOrphanChildren() as a result of a 
REQ_ORPHAN_CHILDREN request .

The GroupRequest contains a single edit part in the getEditParts(), and 
no extended data.

1. What has stopped the ChangeBoundRequests from coming?

2. Is it possible get the location info out of the group request that I 
used to get out of the ChangeBoundRequest?

3. Can anyone point me at any documentation/examples that might be relevant?

Many thanks for any suggestions.
Benedict
