Question

I have a grails domain class that looks like:

class Person {
  String name
  int age
}

When I show the default “create” view (using scaffolding), the age field shows as a required field (with an asterisk next to it). Is there a way to make it show up as non-required and default to blank?

I’ve tried adding

constraints = {
    age blank:true, nullable:true
}

This results in the field being allowed to be empty but it still shows up with the asterisk next to it.

An int is a primitive type and cannot be blank. You would have to change it to an Integer, then a null value would mean that it’s blank.
