[CDO] Cross model references [message #1716178]

I cannot find a way to add a cross model reference in the CDO editor.

Using Eclipse Mars, I checked out a project that has two models from a local CDO repository using the offline mode. The project showed in project explorer. I then opened the CDO editor on one model and tried to load the other model in the same editor using "Load Resource..." action. In there, I selected the "Browse workspace" button, but I did not find the checked out project in the selections. I also noticed the "Import Roots" action in the CDO editor, but it is always greyed out for me.

How is this supposed to work?

That's the expected behavior. Please note that your offline checkout looks like a regular workspace project, but it is
not. All CDO checkouts (whether online or offline) are "just" visually integrated into the Project Explorer view, but
their models generally live in databases. Offline checkouts are based on local databases and online checkouts are based
on remote databases.

The CDO editor should always "see" all models/resources in a repository (=checkout) without the need to import resources
explicitely. Does that not work for you?

That action is only enabled if the selection is a CDOResource. If enabled it can load other resources and *add* their
root objects to the selected CDOResource.

Hi CDO Team,

First, thank you for providing CDO... It is a terrific framework, and I'm using it extensively !

I 'reopen' this thread, since I have the same behaviour (conf. neon & CDO 4.5) : EObjects from other resources in a repository are not presented as candidates for linking. Only EObjects owned by the current edited resource are proposed...

I tried 3 editors (CDOEditor, ECPEditor and a custom one...), they all behave the same way...

I did not find in the source code of cdo where these 'other-resources-eobjects-candidates' are taken into account (looked around CDOItemProvider and CDOItemDescriptor...).

Where should I put a breakpoint to see why other resources are not considered by the CDOEditor ?

Kind regards,
Romain
