Thanks. It working. But the button visibility will never be changed and
button will be visible in this case even if 'visibleFlag' changed to false.
This mean that is your change 'visibleFlag' to false than method onSubmit()
will be call

Look to example
public static boolean visibleFlag = true;
public VisibilityButtonTest()
{
Form form = new Form("form");
add(form);
AjaxButton ajaxButton = new AjaxButton("button1")
{
@Override
public boolean isVisible()
{
Thanks. That would have solved it. I am using setVisible(someFlag) now. Doh!

someFlag is actually a business method that queries the database. But for
the sake of this argument you could model it as static variable. Doesn't
change the problem.

Hi!
It is not a best solutions but you can try it
ajaxButton.add(new AjaxSelfUpdatingTimerBehavior(Duration.milliseconds(1)));

I have an AjaxButton with
@Override
public boolean isVisible() {
return someFlag;
}
In a race condition, if user B sets someFlag to false, and then user A
clicks the button A gets the following exception
org.apache.wicket.WicketRuntimeException: Submit Button buttonName ... is
not visible
