> Key: WICKET-2974
> URL: https://issues.apache.org/jira/browse/WICKET-2974
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.9
> Reporter: Jeremy Thomerson
> Assignee: Jeremy Thomerson
> Priority: Trivial
> Fix For: 1.4.11
>
> Attachments: quickstart.tar.gz, WICKET-2974.patch
>
>
> Consider the following scenario:
> - I have a BasePage that I add a feedback panel to. I want it to only render
> feedback messages that have not been rendered by any other feedback panels
> - I have a feedback border that implements IFeedback, and inside it, I also
> have a FeedbackPanel. I want the feedback panel to only render the messages
> pertaining to the components within the border.
> To accomplish this, I put the creation of the feedback panel in the BasePage
> in onBeforeRender so that my component hierarchy (including the border and
> it's child feedback panel) is created before I add myself to the hierarchy.
> By doing this, I expect my page to be the last IFeedback to appear in the
> feedback list.
> But alas, when Component#beforeRender creates the list of IFeedback
> components, it effectively stops the traversal of any IFeedback#beforeRender
> calls because it does not call internalBeforeRender().
> The attached quickstart demonstrates the problem, and the patch fixes it.
