Put a container (WebMarkupContainer?) around components you want to update,
atatch the behavior to that container and make sure the comapoent you want
to update are "dynamic": meaning that theirs "state" should change every
time they are rendered.
Best,
Ernesto

Re: AW: AbstractAjaxTimerBehavior causes exception
I didn't mean to 'replace' but to 'add'. You need both lines.

AW: AbstractAjaxTimerBehavior causes exception
You're right Ernesto, your example works, but what if I want to replace a whole
panel and not just the model of a label?

Well I think it all boils down to the explanation a gave on my first e-mail:
if you replace the component with a new one that does not have the behavior
then you will get an exception (the same will happend if you remove the
behavior during a round trip). I guess Martin was just trying to say that
you should use the same label...? Did you try the code I posted? It does
work ;-)

AW: AbstractAjaxTimerBehavior causes exception
Hi Martin,
this doesn't work.
@Override
protected void onTimer(AjaxRequestTarget target)
{
Label t2 = new Label("message", "Test " + testCounter);
t2.setOutputMarkupId(true);
test = t2;
testCounter++;
target.addComponent(test);
}
It doesn't throw an exception, but the t2 didn't show up.
I think this is because t2 isn't added to the page.
That’s why there is Component#replaceWith(Component).

Btw, the exception is thrown on first call not on second round trip.

Hi Ernesto,
the label was just an example.
In my app i try to replace the navigation (you remember your suggestion with a
timer?)
The navigation is a panel. So recreate the whole panel and then try to replace
it with the new one.
This is where the AbstractAjaxTimerBehavior comes in.

Hi Chris,
Maybe it is because you are adding the timer to the label and later on
replacing it is another component. Then the second AJAX round trip to the
page will look for the AbstractAjaxTimerBehavior associated to the "message"
component, but the new one does not have associated such a behavior. And you
do not need to replace the label component (just udpate it via AJAX): just
write a model that displays "If you see this message wicket is properly
configured and running" if count =0 and "Test " + testCounter if >0.
Best,
Ernesto

AW: AbstractAjaxTimerBehavior causes exception
Hi Ernesto,
the label was just an example.
In my app i try to replace the navigation (you remember your suggestion with a
timer?)
The navigation is a panel. So recreate the whole panel and then try to replace
it with the new one.
This is where the AbstractAjaxTimerBehavior comes in.

Betreff: Re: AbstractAjaxTimerBehavior causes exception
Hi Chris,
Maybe it is because you are adding the timer to the label and later on
replacing it is another component. Then the second AJAX round trip to the
page will look for the AbstractAjaxTimerBehavior associated to the "message"
component, but the new one does not have associated such a behavior. And you
do not need to replace the label component (just udpate it via AJAX): just
write a model that displays "If you see this message wicket is properly
configured and running" if count =0 and "Test " + testCounter if >0.
Best,
Ernesto
