Explanation of Editing Domain Id in GMF editor [message #177943]

you read

"Generated code always creates new (own) instance of EditingDomain for each
opened diagram editor"

(do not consider the topic of the link, but only the above sentence)

Analyzing the code of my RCP GMF generated editor I understand that, but if
each editor has its own instance of EditingDomain, why all use the same ID
in the registry?

Thanks

By default generated code does not use Registry to create EditingDomain instances.

Yes, all the newly created EditingDomains will have same ID.

Indeed I will have trouble only if I retrive an EditingDomain from the
registry: in this case I'll get the last registered one.
So watching the code the ID is useful only for the enablement of
clientContext...
But at the moment I don't know what is a clientContentx, can you give a
brief description?
As you confirm all EditingDomains have same ID, so this "clientContext" is
always enabled, isn't it?
Thanks

You'll always get the same EditingDomain instance from the registry - this
is whow this registry was created. To get new instance of EditingDomain per
each "pair of eidtors" you have to create your own EditingDomain registry
and create/dispatch existing EditingDomain instances from there using additional
parameters (id of the "pair").

I created my own registry so I have one EditingDomain per file.
Anyway I suppose it is mandatory to set the same ID to all of them to make
the client context working.
Isn't it?

Thanks
