public class FeedbackLabel
extends org.apache.wicket.markup.html.basic.Label

Label displaying feedback messages for FormComponents.

You can use this Label to show the error message near the actual FormComponent, instead of in the FeedbackPanel It's safe to remove the FeedbackPanel if you use this class for every FormComponent in your Form.
