RE: Wicket DatePicker memory leak during ajax rerender?

[Jomar Lorentzen <jo...@statnett.no>]

Bumping this.

Have anybody experienced memory leaks on the client when rerendering datepickers using wickets AjaxRequestTarget#addComponent()?

Subject: Wicket DatePicker memory leak during ajax rerender?

Hi,

we are using the DatePicker in a panel that is rerendered through ajax at a certain interval, and we have noticed
that the DOM reporter in firebug reports that a new function is added each time the DatePicker is rerendered. As none
on our team are really into javascript we're wondering if anybody could say if this is a potential memory leak?

Each time the DatePicker is rerendered a new random javascript function of the type initdateXXX is added to the page. Are these
initXXX references a potential memory leak on the browser, or would they be cleaned up by the browser if firebug had not been running?

initdate838 = function() {
    Wicket.DateTime.init( ... );
};


if (wicketCalendarInitFinished) {
    // when a DatePicker is added via ajax, the loader is already finished, so
    // we call the init function directly.
    initdate838();
} else {
    // when page is rendered, all calendar components will be initialized after
    // the required js libraries have been loaded.
    wicketCalendarInits.push(initdate838);
}
