I have a number of questions in my survey with hard constraints coded in the "constraint" & "constraint_message" fields, but I would also like to include soft constraints (e.g., if an entered value is above the 95th percentile but still plausible, I would like a warning to appear but not prevent the value from being entered). I thought I could do this with "bind::esri:warning" and "bind::esri:warning_message," but in my trials the warning never appears, whether or not the warning condition is met. I have used these constraints successfully with geopoint fields, as described here - can they not also be used for other field types? If not, is there another way that I can create soft constraints for numerical fields?
