When you invoking the page through the browser, you will be typing something
similar to this right?

*http://localhost:<port>/app_name/action_name*

So it will be as *http://localhost:<port>/app_name/Register.*

and i'm not sure whether mentioning *method="{1}"* will call the
*populate *method
there.

try by putting method="populate" also..
