Resource for Adding Connections [message #61797]

Hi There,

When I add a connection between two objects on a diagram and the origin is a
shortcut, the EMF model object which represents the link is created in the
resource containing the orgin's EMF object (IE the resource in which the
origin object is controlled).

Instead, I wish to have the link object added to the EMF resource which is
currently being edited (ie the resource the diagram canvas is mapped to).

This is so that other models in where the same shortcut is used will be
unaffected (I don't want the other models to have visibility to the link
being added).

How does my GMF editor decide which EMF resource to create link objects in
in the case where shortcuts are used? What code would I need to override to
do this?

Thanks

John

It depends on the link type actually. If your link is connected with some
domain-model element then corresponding element has to be created and places
in your domain model in accordance with containment rules determined in mapping
model. You have to specify containmentFeature property for the link mapping
and this is a current way to point where to put newly created link object.
By default link will be created inside domain model element corresponding
to its source.
AFAIU, what you are talking about is pure-visual link – the link without
any underlying domain representation. Such kind of links is not supported
currently. If this is what you want please submit feature request into bugzilla.
