Hi Alex,
Thanks for your reply! :-)

You are right, if I have a single attribute, I can show it as a label.
But assume that I have several different attributes. In this case, I
would like the representation of my objects (the nodes) to have a
single label, but all the other attributes displayed in the compartment.

Yes, I could do that, but that's not quite what I want. I would like to
have it shown as an attribute of the node, not as a link between two
nodes.
I think I was not very clear in my explanations. Imagine it like this:
Current:
Right now, I have an editor that let's me draw nodes. I can then click
on a node, and all the attributes/features of the object represented by
this node are editable in the properties view.
Goal:
My goal would be to get rid of the properties view. Basically, I want
to have an editor that let's me draw nodes, and then these nodes should
have a collapsible compartment containing all attributes/features of
the object represented by this node, editable in the same way as
before. So for example, if my class has a many=false reference called
'ref', then I would want to have a compartment that has an entry called
'ref', and if I click on it a pull-down menu appears that let's me
select the target of the reference. Ideally, I would want to have the
properties view inside the compartment of the node.
I looked at all the information I could find, but I did not see
anything like this. Anyone has an idea?
Best Regards,
Marc

If you have predefined number of String attributes then you can add LabelMapping
for each of them – NodeMapping can hold several LabelMappings. In case you
do not know a number of String attributes from the meta-model definition
(in meta-model you have a feature stringAttributes with multiplicity *) then
you have to use child NodeMapping(s) to model this situation (and it is not
possible to generate corresponding code for now – you have to modify generated
code manually).

This can be implemented even with several LabelMappings – you just have to
define proper composite figure (a hierarchy of figures) in .gmfgraph model
and assign appropriate LabelMapping figure from this hierarchy to each of
LabelMappings.

For now I think you can do that with custom parser or (even better) by defining
+ implementing derive String attribute linkedElementName and using this attribute
in one more LabelMapping.

With string (and hopefully other primitive types) attributes you can use
LabelMapping for each attribute.

This control should be implemented manually. One of the option – try using
LabelMapping as much as it possible and modify generated code at the end.
