For many components, Wicket checks whether you attach them to the
correct tags. Sometimes, addmittedly, this is annoying, though the
idea is that it saves you from making stupid mistakes. In this case,
just either use custom components (or one that can do both, this might
actually be a fairly elegant solution) or wrap those components in
panels (TextAreaPanel and HiddenFieldPanel) and use a <span> tag or
something similar.
