As far as I've learned a CANVAS MAPPING (in gmfmap) is mandatory for every
GMF diagram definition. Within a CANVAS MAPPING you have to set a meta
model element <<R>>, which is typically the root of a containment
hierarchy. Instances of those meta model elements, which are part of this
containment hierarchy (i.e., descendants of <<R>>), can be displayed and
edited in the respective RDiagram.
Suppose we have a meta model element <<AModel>> that has a meta
containment reference to a meta model element <<A>>. If you set DOMAIN
ELEMENT in a CANVAS MAPPING to <<AModel>>, then you can eventually display
and create model elements (instances) of type <<A>> in your ADiagram.
Further suppose we have a meta model element <<BModel>> with a meta
containment reference to a meta model element <<B>>. Furthermore, <<B>>
has a meta reference to <<A>>. Analogously, there is a CANVAS MAPPING with
DOMAIN ELEMENT set to <<BModel>>.
Now my question:
Is it possible to display ANodes within a BDiagram although A-elements are
not contained in the respective BModel-element?
This would be useful in order to visually reflect a reference of some
B-element to some A-element in the BDiagram. Just displaying existing
A-elements in BDiagrams would suffice for me, i.e., I do not want to
_create_ A-elements in BDiagrams.

Thanks for the hint. Now A-shortcuts can be displayed in B-Diagrams.
Now I'm stuck in creating connections from B-Nodes to A-shortcuts. The
diagram editor prohibits these links. Other types of connections from
B-Nodes to B-shortcuts work well.
Are there any restrictions concerning connections from or to shortcuts?

I did so but the gmfgen-Generator seems to completely ignore this link
mapping. Consequently, there are no corresponding command classes for
creation and reorientation generated into bdiagram.edit.commands.
