Igor Vaynberg resolved WICKET-2066.
-----------------------------------
Resolution: Duplicate
Assignee: Igor Vaynberg
already fixed in trunk of 1.3.x and 1.4
> Palette initFactories called more than once if invisible
> --------------------------------------------------------
>
> Key: WICKET-2066
> URL: https://issues.apache.org/jira/browse/WICKET-2066
> Project: Wicket
> Issue Type: Bug
> Components: wicket-extensions
> Affects Versions: 1.3.5
> Reporter: Michael Mosmann
> Assignee: Igor Vaynberg
>
> Using org.apache.wicket.extensions.markup.html.form.palette.Palette.
> Palette is invisible. First time page will render well, but the next action
> will throw an exception.
> I think following code is wrong:
> ---------------------------------------
> protected void onBeforeRender()
> {
> if (!hasBeenRendered())
> {
> initFactories();
> }
> super.onBeforeRender();
> }
> ---------------------------------------
> I did some quick-hacks to set "hasBeenRendered" to true after first request,
> which worked well.
