TextFieldPanel panel=new TextFieldPanel("tfp");
tfp.getTextField().setRequired(true);
tfp.getTextField().setType(Integer.class);
or do what Juergen suggested - it might be a better approach.

Here comes my problem - if you wrap the existing form component, it's much
more difficult to setup it up and 'extend' in code. To make the wrapper
imitatate the interface of wrapped component takes lot of work.
Better would be to leave the component unwrapped and just indicate
(possibly by implementing some interface(which can be totally empty)),
that it has associated markup, so when the component is rendered the
markup would be looked up.
