The primary layer is set to be opaque. It is filling white on top of your
connections. You need to make it transparent.

Your contents EditPart is most likely opaque too.

Your primary layer isn't being targeted because it is transparent.
you will have to change containsPoint(int, int) in the figure that
represents your contents EditPart.
Note that in TransparentFigure, the Layer will *never* be targeted (it will
never return this) unless it is opaque.

Ok, now I subclassed FreeformLayer for my contents edit part figure and
overwrote the methods findFigureAtExcluding and containsPoint, and
everything works fine.
Actually I implemented them _exactly_ like they are allready implemented
in Figure, I re-invented behaviour allready implemented in the
super-super-super-super class. Though working this seems not very
elegant.. Ist there a better way doing this?
I think having a layer that is non-opaque _and_ targetable can be a
widely used component and should be part of the Figure hierarchy.
Thanks for help!
