I don't understand. What's failing? The linkNewValue value is "--New
Value--" so it should pass the required rule. How exactly are you
validating it? If you're using your own validation scheme, I suggest
you check for the linkNewValue value.

I don'use any custom validation, this is what happens:

MainForm Sub Form
=2D-------- ---------
id PK ....
user_id FK <--> id PK

* I choose --New Value-- for user_id and fill in the subform, then fill mai=
n=20
form values and submit
* processForm starts and try to validate main form user_id which must be NO=
T=20
NULL, but now it's NULL since the Sub Form has not been processed yet
* validation fails

To make it work I had to posticipate validation of mainform _after_ subform=
=20
has been processed in the inner loop. This is only necessary in case of=20
linkNewValues have been entered.

This way it works since validation of main form happens after PK "id" of su=
b=20
form has been defined (from the DB).

I was just asking myself of a better way (I don't like to change the code i=
n=20
processForm or subclass it).
