Missing Foreign Key Constraint in SQL

Hi,

I have the problem, that a foreign key constraint is not created in the SQL schema. This occurs, when the primary key is not the column 'id'.

Here is an example:

User:
columns:
username:
type: string(30)
notnull: false
email:
type: string(80)
notnull: true
gender:
type: enum
values: [0,m,f]
notblank: true
notnull: true
birthday:
type: date

Address:
columns:
user_id:
type: integer(4)
unsigned: 1
notnull: true
primary: true
some_data:
type: string(100)
relations:
User:
local: user_id
foreign: id
foreignType: one

The foreign key from contacts to users is not created in der SQL schema. But if I delete the attribute 'primary' at the column 'user_id' (and a primary key 'id' will generated), everything is okay.

Can you help me please?

With kind regards
Stephan
