Re: org.apache.wicket.WicketRuntimeException: Submit Button ... is not visible

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()
   {
 FormVoid form = new FormVoid(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
 

In that case Sven's solution should work.

Re: org.apache.wicket.WicketRuntimeException: Submit Button ... is not visible

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?

org.apache.wicket.WicketRuntimeException: Submit Button ... is not visible

2010-07-08 Thread Conny Kühne 

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?

Hi!
It is not a best solutions but you can try it

ajaxButton.add(new AjaxSelfUpdatingTimerBehavior(Duration.milliseconds(1)));

Thanks. That would have solved it. I am using setVisible(someFlag) now. Doh!
