Hi,
I have another problem regarding this question.
Now every time the page is left the message "Do you want to leave the
page" is popping up,
but when the user correctly fills the form on the page and hits the submit
button
he should be redirected to another page showing the result of his input.
I have tryed this to remove the behavior for a correct submit but the
message is still popping up:
mySubmitButton = new Button("mySubmitButton ") {
@Override
public void onSubmit() {
try {
myTextField.remove(pageExitWarningBehavior);
//tryed both
//pageExitWarningBehavior.detach(myTextField);
}
};
