Okay, that was it... the Convention. I've changed it to skip my
Manager entity completely, meaning I'll have to map all one-to-many
relationships manually in the override for that entity.
public class HasManyConvention : IHasManyConvention {
public bool Accept(IOneToManyPart oneToManyPart) {
if (oneToManyPart.EntityType.Name.Equals("Manager"))
return false;
else
return true;
}
...
}
So v1.0 will not need this workaround?
