Based on a custom field value another custom field should be set as required using validators

Question

I have two custom fields A(number filed) & B(date field). if value of custom field A is not null then custom field B is required, if value of custom field A is null then custom field B is not required, want to accomplish this by writing a simple scripted validator.

Hi, scripted validators are for... validating field values (just before the issue is saved). Not for setting field behaviors (required, ...) which should be applied when a form is opened or a field value is changed.

The solution ? Use scriptrunner Behaviors for setting the behavior (required or not) of field B, every time field A is modified...
