Two graphical views of the same metamodel element [message #172629]

Hi,
I am working on a service modelling GMF editor.

As you can see in this screenshot (http://www.slomic.no/upms-light.gif ) the
interfaces (which contains attributes and operations) is represented as
ellipses in this diagram. Now, I want to create a new view of the interface
details, where you can add operations and attributes (properties). Like if
you double click on the interface ellipse you get another graphical
representation of the very same interface, in new empty view. The interface
is now represented as class (rectangle), where you have attribute and
operation compartments. Is this very difficult to manage in GMF? Could you
maybe send me existing code on a feature like this, and tell in words how I
should proceed to solve this.

Thanks, in advance!

Regards Ismar

Hello Ismar,

Looks like similar question was recently discussed here: http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg10919.html

Hello Ismar,

Some additional information you can find here: http://wiki.eclipse.org/Diagram_Partitioning
In general you don't need to write any code - you have to generate two GMF
diagrams for top-level and child elements and then bind them together to
open second diagram by double-clicking on first one.

Thank you very much Alex! This was exactly what I was looking for, and the
Cheat Sheet in Eclipse did the process much easier to follow.

Have a nice weekend :)

Hello Alex

I have a question regarding the "Diagram Partitioning" guide you
mentioned: Is step 6 of usecase 2 obligated? I never duplicated the
genmodel and changed the "model name" attribute and it works fine. Why
do I have to do this? Isn't it sufficient to change the "package name
prefix" of the sub-diagram?

Regards,

Stefan

Hello Stefan,

To be honest, I'm not an author of this guide, so I do not know why this
"hacky" part was introduced - to my understanding there should be no "hacking"
in DiagramPartitioning. ;-) In any case, answering your question if you are
working with two or more diagrams based on the same meta-model (.ecore file)
then you should take care on uniqueness of some .gmfgen model properties.
All tese properties are mentioned as "unique" in this document: http://wiki.eclipse.org/GMF_GenModel_Hints.
Just search for "unique" string there and read corresponding description.

I can admit your diagrams are working properly even without these properties
set correctly, but in future you can face some problems with this (on future
diagram modification + regeneration). So i suggest to modify corresponding
properties. Hope I answered your question.

I am aware of these unique properties. I was just wondering about this
