You also need to traslate the point, take a look at
org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy on how to do this

hey folks,
thanks for your many many replies. unfortunately i was very busy the
last 2 weeks, so that i have today the first chance to look at your posts.
you have post a lot to determine the location where the actions is
performed. thanks for that. maybe you can give me a short overview how
to deal with request? that would very useful.
thanks again and regards,
rené

hey,
its me again. i solved the problem with the request. it was much easier
than i thought. you have to call just getCommand(Request) of the
responsible edit part. this uses the registered edit policies to create
and return the correct command...
i just want to thank you again. specially nikolas post was very helpful
and works immediately. the use of reflection to get the drop location is
a nice hack and i properly have to pondering for years to come to this
idea. btw: i didn't have to translate the location. it was out of the
box relative to my diagram domain.
best regards,
rené
