class MyCoolLabel extends SimpleFormComponentLabel) {
public MyCoolLabel(String id, FormComponent fc) {
super(id, fc);
//attribute modifier to add the error css class
add(new SimpleAttributeModifier("class", "error") {
boolean isEnabled() {
//only enable if the attached formcomponent is invalid
return !fc.isValid();
}
}
//this is not the cleanest way to do this, it would be better to use true component composition and make this label a panel instead, but i dont want to write all that out - excercise left to the reader
onAfterRender() { getResponse().write("<span class='required'>*</span>"); }
}
then the usage should be something like this:
TextField tf=new TextField("tf").setRequired(true);
add(tf);
add(new MyCoolLabel("label", tf));
<label wicket:id="label">label</label><input type="text" wicket:id="tf"/>
hope this gets you started

Hi
I am writing a simple web application and I'd like to
- mark the label of required fields (ie. a star before the text)
- change the style of the _label_ that belongs to invalid fields
I've found a blog entry about how to change a component's style after
validation but I don't know how to get its HTML label. Is there any
relationship between these Java objects at runtime?
Do you know a solution or best practise?
Thanks,
