3 questions of FormBuilder

1 Does processForm() insert/update the crossLinks DO?
2 My crossLink DO has a two fields primary key, shall
it be detected. In my case, error message shows:
FormBuilder: Primary key not detected - storing data
not possible.
3 If the answer of the 1st question is NO, how can I
identify to insert or update in postProcessForm()?

Thx
