Persistence Api - Foreign Key is always null

I used a script step and called ivy.persistence.persistence.persist(in.user);

My database looks like this: CREATE TABLE [dbo].users ON [PRIMARY] GO

ALTER TABLE [dbo].[opts] WITH CHECK ADD CONSTRAINT [FK34282079933D49] FOREIGN KEY([user_fk_id]) REFERENCES [dbo].[users] ([id]) GO

I think the problem is how I create new Items for the opts list in the user class. In the view i have a selectManyCheckbox: <p:selectManyCheckbox id="select" value="#{data.user.opts}" > <f:selectItem itemLabel="Option 1" itemValue="Option 1" /> <f:selectItem itemLabel="Option 2" itemValue="Option 2" /> <f:converter converterId="conv.OptionConverter" /> </p:selectManyCheckbox>

The con.OptionConverter creates one option object from the given string. @Override public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException { Option option = new Option(); option.setOption(arg2); return option; }

There should also be something like option.setUser_fk(user); so the reference from User to Option is set. This is not possible in the converter because there is no reference to the User object. The only way to set the reference of User in Option is in the User Entity Class where the list is set (or built up). But the generated code only sets the list with empty references to User. So the persistence api can't know their connection. Maybe I'm thinking wrong and build the example wrong but without the references set the persistence api will never set the keys.
