Hi Martin!

I followed your (very good) GMF Tutorial and got everything working!
But I have a certain use case and I hope it is feasable with Teneo ;)!

I want to open one or more graphical editors, each with there own domain
model instance and GMF diagram instance: so (technically speaking)
URIEditorInput shall be not equal between the model instances.

I think this line can help me (copied from the tutorial):
public static final URI DATABASE_URI =
URI.createURI("hbxml://?dsname=mindmap&query1=from Map&query2=from
Diagram");

But certainly I dont know how. Ok, it would be possible to create for each
new diagram editor a DataStore, but ..hmm... answer yourself.

Is there another way to select a specific domain element and the related
diagram element from the Database?! Or is it only possible to store
exactly *one* domain and diagram element to a database?!

Maybe, the solution is rather easy, but I am really new to Teneo...

Thank you in advance!

Best regards,
Matthias

Hi Matthias,
Good that the tutorial works for you. The tutorial is just 2 weeks old so if there are things I need
to change to make it easier then let me know.

Regarding your question, the solution is to use a different query in the uri. The datastore can
remain the same. You can use any hql query in the uri to load a specific diagram and related domain
object(s). So in this way you can for example have a list view which shows the diagrams (you can
load the current set of diagrams from the db using hql either within a resource or outside of a
resource) and when clicking on a diagram open a resource using a specific hql in the uri to open
that diagram:
hbxml://?dsname=mindmap&query1=from Map&query2=from Diagram where name='MySelectedDiagram'

The datastore can be the same for all resources/queries.
