>          Issue Type: Bug
>          Components: Core Library
>    Affects Versions: 4.1.M1
>            Reporter: Arseni Bulatski

> If you have: 
> 1) modeled a primary key as an ObjAttribute, like customerPK 
> 2) modeled it as an object type, like java.lang.Long 
> 3) are using the Cayenne-Generated (Default) PK generation strategy
> Then Cayenne won't generate any PKs for the entity and will just use zero over and over. This can be worked around by switching the attribute's type to a primitive (like long).
