[Grok-dev] validators

[Thomas Bellembois]

Hello Sebastian,

Actually the field I want to validate is *not* one of the 4 fields of my
Molecule class.
I have a 1->* relationship between the "Molecule" container and a "Family"
container.
So I have modified the default Molecule homastemplate file to add a drop
down list with the families.
I want to validate this drop down list (make it required).

Thanks for your help.

Regards,

Thomas
