Dynamic EMF with EditingDomain [message #1233767]

Hi,

I couldn't find any proper solution and do not if there is any.

I've got created dynamically EClasses and DynamicEObjects for these classes.
What I would like to do is to somehow create dynamic editing domain for my EObjects.

This is an example:

EClass eClass = ...;
DynamicEObjectImpl domainObject = new DynamicEObjectImpl( eClass );
ReflectiveItemProviderAdapterFactory reflectiveItemProviderAdapterFactory =
            new ReflectiveItemProviderAdapterFactory();

ComposedAdapterFactory copm =
            new ComposedAdapterFactory( ComposedAdapterFactory.Descriptor.Registry.INSTANCE );
copm.addAdapterFactory( reflectiveItemProviderAdapterFactory );

AdapterFactoryEditingDomain editingDomain =
   new AdapterFactoryEditingDomain( copm, new BasicCommandStack() );

domainObject .eAdapters().add( new AdapterFactoryEditingDomain.EditingDomainProvider( editingDomain ) );

I don't have any resource for where object could be contained.
Even if I created one, still doesn't work.

My main idea to is to be able to open EMF Client Platform editor using dynamic EMF.

Any ideas what I am doing wrong?

Cheers,
Paweł.

This looks weird, as opposed to EcoreUtil.create(), or
ePackage.getEFactoryInstance().create(...)

If you look at AdapterFactoryEditingDomain.getEditingDomainFor(EObject),
you see that the editing domain provider is only searched on the
object's Resource, not the object itself. What doesn't work exactly,
even if you add the object to a resource?

EcoreUtil.create() in the end does the same for me as new DynamicEObject(eClass).

It is hard to say what doesn't work exactly. I know that resource is needed so I did eventually. I've been trying to open ECP editor which occurred to be empty. When I had EMF.edit plugin provided then everything worked fine of course.
I guess something is missing still. Maybe I need to register editing domain somehow somewhere. Looks like either reflectiveItemProviderAdapterFactory is not enough or resource.eAdapters().add() is not enough.
To be clear, to have a resource I did only new ResourceImpl() and added my object there. Maybe this is wrong. I did not provided any resource set.

Still it looks weird :p

I have no idea what ECP is. Did you try to open your model with the
reflective emf model editor? If that works, it's an ECP thing..

IIRC, the reflective model editor (actually, all EMF generated editors)
requires an URIEditorInput and manages the resource loading itself, you
cannot pass it an already loaded resource without customisation. Maybe
the same thing happens for ECP.. Did you try to save your resource and
then pass it to the editor?
