Hi guys.
I have a question about form validation. My form has a field "username". I
want to check if entered username already exists in database.
I try to use async validator function.
...
var userNameValidator = new qx.ui.form.validation.AsyncValidator(
function(validator, value) {
var userExist = that.db.checkUserExistence(value);
if (userExist) {
var message = "A user with the same name exists in the
database!";
userName.setInvalidMessage(message);
userName.setValid(false);
}else{
userName.setValid(true);
}});
validator.add(userName, userNameValidator);
validator.addListener("complete", function() {
if (validator.getValid()) {
alert('Validation ok!')
}}, this);
But I use userName.setValid(true) an event "validator.complete" doesn't
fire.
