I have been using the logic example to follow along and build a
graphical editor. I am able to drop nodes (I extended draw2d.Label) on
the editor and am trying to get connections between them.

The first problem is that when I click on the terminal of a node with
the Connection tool selected in the palette, the connection is drawn
from the upper corner of the diagram instead of at the terminal of the node.

I have searched high and low through the logic example and I do not see
what I am missing.

Any help would be greatly appreciated.

Thanks,
Phil

What edit policies have you installed for your edit parts that are being
connected?

One thing you may want to try is to set a breakpoint in handleButtonDown in
ConnectionCreationTool which will halt execution when you mouse down to
create a connection, and then compare the flow of execution with the
LogicEditor to see what's different.

Whitney,

Thanks for the help. Although chalk this one up to operator error. :)
It seems that as I am going about the development I am adding pieces as
I need them, well, all the getters and setters that I added to the base
editor part to handle the connections had already been implmented on the
extended classes to return null. So GEF was never seeing the connection
anchors.

DOH!

You are not implementing the NodeEditPart interface. The tutorial talks
about this interface.
