Hi,
I have an editor for a metamodel that consist basically just of the
classes "Node" and "Edge". Now I want to add any number of
specialization types for these basic types (based on another model)
dynamically (so I cant use the elementTypes extension point).
In my palette I want to have a Creation Tool for any of my
specialization types. What I did so far:
- I created new specialization types for my basic element types "Node"
and "Edge" and registered them to the ElementTypeRegistry.
- I bound these specialization types to the client context of my editor.
- I created an palette entry for these types.
Now the specialization types are shown on the palette but I cannot add
them to the diagram canvas (only the basic ElementTypes of "Node" and
"Edge").
Is there a special thing I have to add, so my specialization types can
be added to the canvas?
Thank you for helping, Chris Klapdohr

Hi David,
thanks for your answer.
I have implemented the Interface IHintedType, but I still get the
"not-allowed" cursor by trying to add one of my SpecializationTypes.
By debugging I found, that a node that can be added to the canvas
unlike my SpecializationTypes gets a Comand "cmd" in the method "Command
getCommand(Request request)" which is not null, so the method
_disableCanonicalEditPolicyList.addAll(disableCanonicalFor(_ request)) is
called. In case of adding one of my SpecializaitonTypes the Command cmd
is allways null.
Any ideas whats missing here?
Best regard, Chris

I have solved the my problem by adding the specialization types to the
KNOWN_ELEMENT_TYPES in my generated class xxxElementTypes.

Oh, I forgot to mention, that you have to update the method
"getCreateCommand" in your xxxItemSemanticEditPolicy, so "true" is
returned if the element type of the request is your basic element type
(like generated) OR a specialization type of it.
