Inheritance inside a Container causes WicketRuntimeException
------------------------------------------------------------
Key: WICKET-1712
URL: https://issues.apache.org/jira/browse/WICKET-1712
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.3
Environment: Linux , resin-3.0.24 , Wicket 1.3.3
Reporter: smallufo

To summarize :
I want to make a "Widget" , AbstractPullDownPanel , that I can "collapse /
expand" it.
Any panel extends AbstractPullDownPanel will have a title bar , with
ajax-enabled collapse / expand link in the upper right of the panel.
When the panel is collapsed , it will leave a title bar there.
The state of the panel (open / closed) is stored in WebSession
Now , I have a RadioGroupPanel extends AbstractPullDownPanel .
If it only contains an empty RadioGroup :
RadioGroup selectDeselectGroup = new RadioGroup("selectDeselectGroup");
Everything works fine , no matter the panel is collapsed or expanded , page
reloading is ok....
But if I add Radio(s) inside the RadioGroup , only when the panel is expanded ,
page-reloading is ok.
If the panel is collapsed , page reloading will throw WicketRuntimeException :
WicketMessage: The component(s) below failed to render. A common problem is
that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
1. [MarkupContainer [Component id = selectDeselectGroup, page =
destiny.wicket.test.TestPage, path =
1:radioGroupPanel:selectDeselectGroup.RadioGroup, isVisible = true, isVersioned
= false]]
2. [MarkupContainer [Component id = selectAll, page =
destiny.wicket.test.TestPage, path =
1:radioGroupPanel:selectDeselectGroup:selectAll.Radio, isVisible = true,
isVersioned = false]]
3. [MarkupContainer [Component id = deselectAll, page =
destiny.wicket.test.TestPage, path =
1:radioGroupPanel:selectDeselectGroup:deselectAll.Radio, isVisible = true,
isVersioned = false]]
