Thank you again:)
I used:
@OnEvent(component = "userEditor", value=Form.PREPARE) public void
instantiateObject() {
user = new User();
}
This produces the form but without a dropdown of occupation.
The user.occupation is just an occupation object and not a list so how do
you handle foreign keys in beaneditform?

You're welcome!

When instantiating a class, BeanEditForm uses the same approach as the one
used when you declare some service via ServiceBinder.bind(...). I suggest
you to instantiate you class yourself before the form is rendered:
@OnEvent(component = "yourBeanEditFormIdHere", value=Form.PREPARE)
public void instantiateObject() {
yourField = new Users(......);
}
The prepare event of the Form component is fired before the component is
rendered and before the form values are set in your object(s) fields.
Another suggestions: rename your Users class to User. :)
