The NumberTranslator has an omitZero property, which by default is true
(personally, I think the more intuitive default value should be false).
You can override this property in your translator binding like so:

There are many ways to do this. Perhaps the most standard way is to
register one or more javax.servlet.ServletContextListener objects in
your web.xml.

If you want to bind your field to a number with 10 digits, you should
not need to write your own validator nor use custom logic in your listener.
