org.apache.wicket.WicketRuntimeException: Submit Button ... is not
visible
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
Any ideas how to circumvent this?
Conny

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

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

It can't work.
Please, see org.apache.wicket.Component.internalBeforeRender() method.
Method onBeforeRendering() colling only in case when visibility of component
is true.
In our example boolean variable 'available' false by default. This mean that
component never be rendered.
Can someone explain what I do not understand?

In that case Sven's solution should work.

But question is still open:)
Look to example
public static boolean visibleFlag = true;
public VisibilityButtonTest()
{
Form<Void> form = new Form<Void>("form");
add(form);
AjaxButton ajaxButton = new AjaxButton("button1")
{
@Override
public boolean isVisible()
{
return visibleFlag;
}
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
// do nothing
}
};
form.add(ajaxButton);
form.add(new AjaxButton("button2")
{
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
visibleFlag = false;
}
});
}
after open this page press to button2 and after to button1

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.
