public class FormComponentFeedbackIndicator
extends Panel
implements IFeedback

A panel that hides or shows itself depending on whether there are feedback messages for a given message filter. If a component is set using setIndicatorFor(Component), then the indicator is visible when the given component has an error. The default content for this indicator is a red star, but you can subclass this panel and provide your own markup to give any custom look you desire.
