Hi,
The code in the AsyncValidator is not much different from the timer code.
Just replace the timer with an async call to your backend and thats it. And
I think its important to do that sync because you don't want the UI to
freeze until you server has done the validation.
Here is some maybe not
Martin, I don't need a server code, I want to see only code insight the
qx.ui.form.validation.AsyncValidator. I want to check username for existence
in database. Should I use asynchronous request to do it? If yes, where
should I place a callback function?

Hi,
we currently don't have much server code in our demos. Thats why I used a
timeout which simulates the async behavior. Currently, there is no time to
set up such a demo but you can open a bug report for that if you want to see
such a demo.
Regards,
Martin

In the demo there is a timeout instead of a server async server request.

Sorry, it seems it was my mistake.
I replaced userName.setValid(true) with validator.setValid(true) an it

Hello Alexander,
this could have a couple of reasons. Do you have other fields added to this
validator, does the callback work? (Where is the callback sync anyway?) And
so on... Have you seen the demo which uses the AsyncValidation? Maybe you
can see the difference there?

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 u
