Nick Belaevski updated RF-6027:
-------------------------------
Assignee: Pavel Yaschenko (was: Tsikhon Kuprevich)
> ModalPanel: incomplete cleanup at destroy method
> ------------------------------------------------
>
> Key: RF-6027
> URL: https://jira.jboss.org/jira/browse/RF-6027
> Project: RichFaces
> Issue Type: Bug
> Affects Versions: 3.2.2
> Environment: IE7
> Reporter: Sergey Astakhov
> Assignee: Pavel Yaschenko
> Fix For: 3.3.1
>
>
> Extracts from modalPanel.js:
> show():
> ...
> if (this.options.autosized) {
> this.observerSize =
> window.setInterval(this.correctShadowSize.bindAsEventListener(this), 500);
> }
> ...
> hide():
> ...
> if (this.options.autosized) {
> window.clearInterval(this.observerSize);
> }
> ...
> You are setting up timer listener when ModalPanel is displayed, and clear it
> when hiding. All works fine when show() is paired with hide(), but there is
> exist a possibilities when region with panel is replaced by ajax response,
> then on panel is called only the destroy() method, but not hide(). In this
> case timer is rest in memory and cause flickering of shadow of panel if you
> try to display the panel (replaced by ajax) again (and may cause memory
> leaks).
> As workaround I tried to include cleanup code in destroy() method:
> ---
> ModalPanel.prototype.originalModalDestroy = ModalPanel.prototype.destroy;
> ModalPanel.prototype.destroy = function(id, options)
> {
> if( this.shown && this.options.autosized )
> {
> window.clearInterval(this.observerSize);
> }
> return this.originalModalDestroy(id, options);
> };
> ---
> After this change the problems seems to gone away.
