IFeedback that is child of IFeedback gets added to the FEEDBACK_LIST too late
-----------------------------------------------------------------------------
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: 1.4.10
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.
