Igor Vaynberg resolved WICKET-2942.
-----------------------------------

      Assignee: Igor Vaynberg
    Resolution: Cannot Reproduce

i tried with ie8, ffox, chrome. neither one of them leak. you just have to wait long enough to let the browser get enough memory. for example, both all browsers ramped up to about 1.2gb ram and then hovered around there going up and down. of course, if you do not wait for your browser to ramp up it may look like a memory leak.

> Even in simple example, which uses AjaxSelfUpdatingTimerBehavior memory leaks in both browser occurs.
> Tested example:
> 1. java file:
> import org.apache.wicket.ajax.AjaxSelfUpdatingTimerBehavior;
> import org.apache.wicket.markup.html.WebMarkupContainer;
> import org.apache.wicket.markup.html.WebPage;
> import org.apache.wicket.markup.html.basic.Label;
> import org.apache.wicket.markup.repeater.RepeatingView;
> import org.apache.wicket.util.time.Duration;
> public class TestPage extends WebPage {
>     public TestPage() {
>         WebMarkupContainer table = new WebMarkupContainer("testTable");
>         add(table);
>         RepeatingView rows = new RepeatingView("row");
>         table.add(rows);
>         for (int i = 0; i < 10000; i++) {
>             WebMarkupContainer item = new WebMarkupContainer(rows.newChildId());
>             rows.add(item);
>             RepeatingView cols = new RepeatingView("col");
>             item.add(cols);
>             for (int j = 0; j < 15; j++) {
>                 WebMarkupContainer item2 = new WebMarkupContainer(cols.newChildId());
>                 cols.add(item2);
>                 item2.add(new Label("value", "test valueeeeeeeeeee"));
>             }
>         }
>         table.add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(5)));
>     }
