Yeah, well done. Writing components in Tapestry is so easy and fun. :-)
You can probably delete the _request and have an empty processSubmission() too.

The new code works fine!
public class HiddenField extends AbstractField {
@Parameter(required = true, principal = true)
private String _value;
@Inject
private Request _request;
final void afterRender(MarkupWriter writer) {
writer.end(); // input
}
@Override
protected void processSubmission(FormSupport formSupport, String
elementName) {
// TODO Auto-generated method stub
_value = _request.getParameter(elementName);
}
void beginRender(MarkupWriter writer) {
writer.element("input", "type", "hidden", "name", getElementName(),
"id", getClientId(), "value","");
}
}

Sure. It should be pretty simple. First, please define "doesn't work".
Does anything get written into the html?
Also, you probably want to extend AbstractField, not AbstractTextField.
Cheers,
Nick.
