Re: [Tapestry-developer] Extending Textfield Question

Hm.  First, you'd have to call your property styleClass.

Second, its ok for an inherited informal parameter to be null, and its ok to 
use <inherited-binding> to bind informal parameters as well as formal, so you 
could do something like:

<component id="submit" type="Submit">
  <inherited-binding name="class" parameter-name="submitClass"/>
 ...
