I have met a situation that i could not add an attribute as a user-defined type.
There are two classes named Person and Motor.
In class Motor, I want to add an attribute named man whose type is Person.
However, there is no "Person" type in the field of EType that I can choose.
So my question is, does Ecore tool not offer such function to a designer to do so?
If Ecore tool does, how can I add an user-defined type attribute successfully?
Thanks for your help. Hope to receive your reply soon:)
