I'm creating a suitelet for custom record entry of case surveys. Users won't have access to the record, so I'm creating a suitelet with admin access. How can I make fields required? I'm used to using alerts in a UE script, but I'm not sure if there's any way to change field properties or prevent submission if required fields are not filled out.

When making the fields with serverWidget there is an isMandatory property you tag on after the field is created. You could also make them mandatory in a client script if the mandatory-ness is dynamic.

I see that now. Thanks
