Hi all,
I am trying the new command-related services in Sirius 4.0, especially the performSetCommand(). In the documentation you can read:
Quote:The implementation of these services delegate to the ItemProviderAdapter.createCommand() method, so any customization made in the ItemProviderAdapter 's implementation will be taken into account.
In the corresponding ItemProviderAdapters of my model I have made several customizations, but they are not used when I call for example performSetCommand(). Debugging the Sirius code shows that performSetCommand() indeed is called as expected and a standard SetCommand is performed. But my customizations are not used, since the Sirius EditingDomain (TransActionionalEditingDomainImpl) is not aware of the ItemProviders of my model, since
IEditingDomainItemProvider editingDomainItemProvider =
(IEditingDomainItemProvider)
adapterFactory.adapt(owner, IEditingDomainItemProvider.class);
Did I miss something? Do I have to add my models AdapterFactories to the EditingDomain of Sirius myself? And if so, how can I do it?
Any help would be greatly appreciated.

In which context do you try this performSetCommand() ? In a model
operation of a tool ? Is your object alreayd attached to its
parent/resource ?

You should not have to do so: the editing domain is initialized with a
ComposedAdapterFactory aware of the
ComposedAdatperFactory.Descriptor.Registry.INSTANCE, so if you have
properly declared your EMF.edit plugin, it should work.
org.eclipse.sirius.ext.emf.edit.EditingDomainServices.getEditingDomain(EObject)
calls
org.eclipse.emf.edit.domain.AdapterFactoryEditingDomain.getEditingDomainFor(EObject)
which will return true if the object's resoure is null.
But the fact that you have a command shows that the domain is found.
It looks like the ReflectiveItemProviderAdapterFactory has been found
instead of yours.
Could you check your extension to <extension
point="org.eclipse.emf.edit.itemProviderAdapterFactories">, its
supported type, the uri and the class ?

My question was in case your extension point had been ok, to identify
where to check the initalization of the tool execution context.
