[jira] Commented: (WICKET-1712) Inheritance inside a Container throws WicketRuntimeException

["smallufo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-1712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12670014#action_12670014 ] 

smallufo commented on WICKET-1712:
----------------------------------

But if I implement this "Window-like" panel by extending Border
I have no way to notify the collapse/expand events to the containing content
.

In my previous implementation , the AbstractPullDownPanel defines two
methods invisible()/visible() for successor to override , if they want to
handle the collapse / expand events.

But if I implement it in Border , and place the "expand / collapse" link to
the top of the Border .
Because the border is added to the panel , I find no way to notify the
"expand/collapse" events to its containing panel.

I don't know how to gracefully solve this problem just like the
AbstractPullDownPanel ... (define two methods for successor to override)

Does anybody know how to accomplish it ?

Thank you.

> 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).
