If you are going to have to add extra containers anyway, you could try it the
way we do it on my project.
In the html, we add both a label and input element with wicket ids. to keep
it simple, the label's id is the same as the related component's id with
"label" appended to it.
Then, we have a createLabel method that takes the Component and it
automatically adds the label with the proper id.
TextField message = new TextField("message");
message.setLabel(new Model("Message"));
add(message);
createFieldLabel(this, message);
protected FormComponentLabel createFieldLabel(final MarkupContainer
container, final FormComponent formComponent) {
FormComponentLabel label = new FieldLabel(formComponent.getId() +
"Label",
formComponent);
container.add(label);
return label;
}
