The MSLEditingDomain has been fixed so that it will delegate calls such as createCommand(), createOverrideCommand() and getCommandStack() to inner adapter factory editing domain. A client can use this part of the EditingDomain API but the resulting command execution will fail because of an MSLActionProtocolException. In the MSL Library Editor context, this shows the user that they cannot perform any modification to the resource without opening a write action in an undo interval. A similar exception is thrown if the user were to attempt to modify one of the structural features of an object with the properties view. This is the intent of the example editor.
