如何重写Apache Wicket中的表单验证方法？

Question

When we submit the form without filling in the required ( setRequired(true) ) field values, it errors out. I want to override the method that displays these error messages.

PS I know how to customize these error messages by properties files.

To display the error messages you have to use FeedbackPanel (or actually any class implementing IFeedback ). By overriding org.apache.wicket.markup.html.panel.FeedbackPanel#newMessageDisplayComponent() you can use a custom Component to render each feedback message.
