It's not about right and wrong. You're asking questions about EMF's core
runtime, not about any of the EMFT components, and questions like that
are bertter better on the EMF newsgroup.

Yes, you can add an adapter to the eAdapters list of any
Notifier/EObject and then receive Notifications about all changes that
happen to that object.

am i wrong hier with my Topic?
f.e. in my Model there are many Graphs( there are only Nodes and Edges which have bidirektional containment Relationship). These Graphs have close Relationships each other. So separate one Graph from these Graphs and try to modify it. meanwhile i want to send other Graphs a change Message, so that let they know it was something changed hier.
can i delegate this Message in EMF?
Thank you
