public class FormComponentFeedbackBorder
extends Border
implements IFeedback

A border that can be placed around a form component to indicate when the bordered child/children has a validation error. A child of the border named "errorIndicator" will be shown and hidden depending on whether the child has an error. A typical error indicator might be a little red asterisk.

Note: Since this border checks its children do not use TransparentWebMarkupContainer and add the children directly into the border
