isValid and getFeedbackMessage

[Altuğ Bilgin Altıntaş]

Hi,

Can i change TextField's (FormComponent) valid status and set a custom error
message from outside ? Like :

TextField<String> txtname = new TextField<String>(..)
// setting valid false and custom error message

if (!txtname.isValid) {
  // get custom error message now
  String error = txtname.getFeedbackMessage().getMessage().toString()
}

Thanks.
