Hi Ed,
thank you for your fast reply. I tried using the CreateChildrenCommand by
getting a command from the AdapterFactoryEditingDomain but it somehow did
not work out for me. I don't quite get how to use those commands exactly
to achieve what I need.
If I would use the
AdapterFactoryEditingDomain.createCinnabd(CreateChildCommand .class, new
CommandParameters(owner, feature, collection<?>) what would be the
parameters for the CommandParameters.
I have my Editor and therefor I could access everything in it. I still
couldn't figure out how to get the owner for my new object (i supposed
this should be the parent node?) If I thate the resourceset from my editor
and iterate through its contents then I can get my rootNodeImpl and get
all the childNodes and find out where to put my new created node, but this
seems to be kind of a weird way to achieve this?
Also, what would be the feature atribute I would have to set there? From
debuggin I think the collection I have to pass the commandParameters I can
get by calling getNewChildDescriptors from my editingDomain?
Thank you for your help.
Best regards,
Artur

Artur,
Probably it's easier to look at using an AddCommand. If you look at the
Javadoc, it shows that an AddCommand will do the equivalent of this:
*
((EList)((EObject)owner).eGet((EStructuralFeature)feature)). addAll(index,
(Collection)collection);
Or in terms of generated code it's equivalent to
owner.getFoo().addAll(listOfFoos).
In the end, you do have to determine which object you're adding stuff
to (the owner), which feature you're adding it to (foo), and what's
being added...

Probably it's easier to look at using an AddCommand.

Ed,
that worked very nice. The AddCommand added my child element to the tree
and set the editor dirty. Also the undo stuff works.
One last question :)
To create the command I need the owner which would be a category Node for
my model. So currently I am doing this to get the owner (which I think is
not the right way):
I get the EMF editor and get the EditingDomain. From the editingDomain I
get the Resourceset and from that I get the resources. Then I iterate
through the resources and find the XMIResourceImpl. After this I iterate
through those contents and find my root node. From that node I get the
owner.
Is there a more sane way of doing this?
Best regards,
Artur

Artur,
It sounds reasonable. You need to traverse to the object from the
resource set, if you have no other way of knowing which object to access....
