problem with page refresh
Hi guys, I ran into a problem lately,
I have an instance variable in my panel and an ajax behaviour
public final class ScrollLoader extends Panel implements IHeaderContributor
{
int number = 0;
private AbstractDefaultAjaxBehavior b;
..
//constructor
public Scrolloader (...){
b = new AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
System.out.println(number is +number);
number++;
}
}
..
}
}
when I click a button on the page, with ajax I call this behaviour and the
number is incremented.
if I click on the buttons 5 times, the number increments to 0,1,2,3,4,
then if I refresh the page and than click on the button other 5 times, the
number goes to 9 (5,6,7,8,9)
//so far, so good!
but now if I refresh the page again, and I click on the button the number
starts incrementing from 4 and not from 9!! (so If I press the button 5
times I see again 5,6,7,8,9 and not 10,11,12..)
same problem when I load the page for the first time:
If I *refresh * the page before incrementing the value, the number starts
incrementing from 0
so i get 0,1,2,3,4
if I refresh again, the number starts incrementing from 0 again..
in other words when I refresh the page 2, 3, 4 times, the number starts
incrementing from the value reached before the first refresh, after that
first refresh any change to the number is lost..
so what do I do wrong?
sorry if this is a bit confusing,
and thanks for your help!

Re: problem with page refresh
Hi,
I see you use 1.4.x (implementing IHeaderContributor). Which url
coding strategy is used for this page ?
I'd recommend you to use HybridUrlCodingStrategy because it keeps the
page id in the url (something like: my/page.4)
This is the reason why urls for stateful pages in Wicket 1.5 also keep
the pageId in the url (my/page?4). This way even the refresh keeps the
last state of the page. Without the page id Wicket would create a new
instance of the page.

Re: problem with page refresh
Hi Ale. I had a very similar problem, and I was able to get the behavior I
expected by changing the render strategy to ONE_PASS_RENDER in
Application.init(). Have a look at this
