Here is a schematic view of the form I have: (*) choice 1 [X] option 1 [_] option 2 [_] option 3 ( ) choice 2
When "choice 1" is checked, at least one of the three options should be checked.
I wanted to write a specific validator for the options but...as the "options" multi-checkbox is not required (as they are ignored if choice 2 is checked), when no option is checked, the validator is not executed at all.
Does anybody have a solution for it? Thanks -- Guillaume ORIOL
