Igor Vaynberg updated WICKET-1275:
----------------------------------
Assignee: Matej Knopp
Summary: OnBefore(After?)Render does not properly cascade to descendants
of components added to ajax request target (was: Displaying a Palette via AJAX)
i tried to look into it, but ran out of time. matej can you take a look, youve
actually tweaked the request target recently so maybe this is a regression.
basically we never cascade the onbeforerender() to all children. we call
component.preparerender() and that calls onbeforerender() but only on that
component.
this error happens because palette creates the recorder lazily in its
onbeforerender callback, and since that is never invoked...

> I attached an example project so you can see exactly what the problem is.
> Just unzip, mvn eclipse:eclipse (or whatever) and import the project and run
> it.
> Basically I have a couple radio buttons and want to display different
> Palettes and other options based on the radio button picked. When I click on
> a radio button I get the following error:
> WicketMessage: Unable to find component with id 'recorder' in
> [MarkupContainer [Component id = options1Palette, page = wicketbug.Home, path
> = 10:form:container:options1Palette.Palette, isVisible = true, isVersioned =
> true]]. This means that you declared wicket:id=recorder in your markup, but
> that you either did not add the component to your page at all, or that the
> hierarchy does not match.
> [markup =
> jar:file:/home/jtoth/.m2/repository/org/apache/wicket/wicket-extensions/1.3.0/wicket-extensions-1.3.0.jar!/org/apache/wicket/extensions/markup/html/form/palette/Palette.html
> If you comment lines 73 and 74 in Home.java so the palettes are displayed
> from the start everything works fine.
> Let me know if you need anything else.
> Thanks!
