Is it possible to activate a custom validator via props? as isRequired

     {
         "type": "text",
         "name": "email",
         "title": "Email",
         "isUnique": true,

functions isUnique(params){
.......
}

Survey

@jmlopezo You can extend the library. You can add "isUnique" property into question and then write a code to make sure question value is unique. You can use survey.onValidateQuestion event.

survey.onValidateQuestion.add((sender, options) {
  if(options.question.isUnique) {
   //check that this question value is unique and set options.error if it is not
 }
});

Thank you, Andrew
