2 GMF Diagrams based on the same model at runtime [message #199466]

Hi all,

I am currently working on a project in which I need to work in 2 or more GMF
diagrams which uses the same model (ecore).

The problem is that the second GMF diagram needs to define its elements
based on the result of the FIRST GMF diagram.

BUT even thought, both of them are running on the same eclipse, I cannot
access the elements created BY the first diagram on the second one.

(Both diagrams use the SAME ecore, and generated classes at runtime.).

Does anyone know how can I do that?

I think it is because both diagrams DO NOT persist the results on the same
"model" file (the result of a GMF diagram, is a diagram file which persists
the graphical things, and a "model file").

Is there a way to make 2 GMF diagrams persist its results on the same
"model" file?

Or is there a way to "import" the "model" results of 1 GMF diagram, into the
"model file" in the second diagram?

Any help appreciated.

Thanks in advance

Hello Santiago,

Try calling "Initialize <2-nd>_diagram diagram file" popup menu action on
the .model file created by first diagram. As a result you should be able
to choose elements created on 1-st diagram and create 2-nd diagram for them.
This is a way to "link" two diagrams with the same model file. In addition
diagram partitioning feature can be useful for youe use cases: http://wiki.eclipse.org/GMF_2.0_New_and_Noteworthy#Basic_sup port_for_diagram_partitioning.

There are a couple of existing news postings on diagram partitioning...

Hello, and thanks for your answer..
ill check the links, and try them in my project...

but I what i need in my project is to persist the behaviour of the "Add
Resource.." functionality (Which links the 2 diagram file).
Is there a way i could make this link between the two diagrams permanent?
either at runtime, programatically or modifying the .xml?

thanks in advance.

You can load second diagram in generated ???DocumentProvider (see .createDocument()
method as an entry point). This is a place where Diagram instance is loaded
from EMF Resource, so you can load another instance there based on som information
you have concerning the link between these two diagrams. If you need to store
this knowledge in a notation model - try using DiagramLinkStyle for it.
