I had a form with checks that a birth date field is required and checks the format in a call back function. It was working correctly, repopulating when the form has validation errors.
Now, I have to add in complexity where the user can provide age instead and the application will compute the year and using the current date and month to estimate the birth date. The computation is now done in the controller and the values are pushed to the forms.
Somehow, the set_value is not repopulating age and birth_date. The form fills up correctly the variable values if I don't use set_value or I turn off the validation for these fields.
Is this a bug or am I doing it wrong?
