New to GEF - still fighting my way through the abstraction layers and
spending half my time in the example code.
I have a diagram "D" with a child object "O". "O" has a child, "C". My
diagram edit part has edit policies for the COMPONENT_ROLE and the
LAYOUT_ROLE, very similar to the Shapes Example.
My ObjectEditPart "O" has edit policies for COMPONENT_ROLE,
GRAPHICAL_NODE_ROLE, CONTAINER_ROLE and LAYOUT_ROLE.
Both of these layout roles are extensions of XYLayoutEditPolicy.
My Child edit part has edit policies for the COMPONENT_ROLE and the
GRAPHICAL_NODE_ROLE.
I can move "O" around freely within "D" with no problem. I can also
create an instance of "C" within "O". At the time of creation, "C" is
selected, and by grabbing its border, I'm able to move it around within
"O". However, once "C" is deselected, I'm unable to select it again.
When I click on it, its parent, "O" is selected. Could someone please
tell me what I've overlooked here.
Thanks in advance
Jerry

More information -
Child item "C" is not getting selected. (setSelection() is never called),
so it's not just a feedback issue.
However, I can select it by dragging a rectangle around it if I begin my
drag from outside its parent.
I've scoured this newsgroup and I see several posts that are related to
this issue, but none that hit it on the head and give a thorough
explanation of what is required.
Thanks
Jerry

It sounds like either
a) the selection tool never targets that editpart as the mouse moves
b) the editpart does not return a SelectEditPartTracker or subclass of it
