How to avoid superfluous Wicket log warnings when using field-specific FeedbackLabels?
问题 I'm using "FeedbackLabels" to show component-specific validation messages, based on ideas and code in this blog post: User friendly form validation with Wicket. Problem is, pages using such FeedbackLabels for validation messages flood the log with superfluous warnings: 2012-05-04 10:43:32,824 ["http-bio-8080"-exec-6] WARN org.apache.wicket.protocol.http.WebSession - Component-targetted feedback message was left unrendered. This could be because you are missing a FeedbackPanel on the page.
