But I'm not sure if this is what you are looking for.
import wicket.markup.html.form.TextField ;
import wicket.markup.transformer.AbstractTransformerBehavior;
import wicket.model.IModel;
public class MyTextField extends TextField {
public MyTextField(String id, IModel model) {
super(id, model);
add(new AbstractTransformerBehavior() {
@Override
public CharSequence transform(Component component, String output)
throws Exception {
TextField textField = (TextField) component;
if (textField.hasErrorMessage()) {
return output + "<span style='color:red;'>*</span>";
} else {
return output;
}
}
});
}
}
Markup - <input type="text" wicket:id="name"/>
Java - add(new MyTextField("name"));
But may be you can wait for one of the Wicket commiter's to confirm if this is an *acceptable* usage of ITransformer.
thanks,

Year, thanks, but...
What I really want is to combine the border AND the component (like TextField) into my own custom component! This way I would considerably reduce the amount of HTML and Java code.
Isn't it supposed to be the main advantage of Wicket - the ability to easily create own custom components? ;-)

Personally, I think this -
wicket.markup.html.form.validation.FormComponentFeedbackBorder is nice. So
now you just need a panel with your standard form component and this border
attached. You can ofcourse build your own Border using
FormComponentFeedbackBorder as a starting point.
