By default, no instance is automatically created for a reference, whether the lower bound is 0 or 1.
The main difference when you change the lower bound, I think, is during the validation of your model : if a lower bound 1 reference is null, you'll have an error.
Now, I suppose your need is to automatically create an instance of B when you create A, isn't it ?
I'm not sure what is the best approach, but you can :
- edit your ModelFactory.createA() (in the model generated code) (no, never do that)
- edit the create command in the edit model (in the edit generated code).
