grails countrySelect tag - default value

The countrySelect tag says it has the following attribute:

• default (optional) - The ISO code of the default country to display if value is not set

I removed the value attribute altogether, and still can't get it to display "United States" as the default selection when I do:

  <g:countrySelect name="ship.country" default="usa" />

     or

  <g:countrySelect name="ship.country" default="United St开发者_JAVA百科ates" />

What am I doing wrong .. what else should I try?

Thanks

<g:countrySelect name="ship.country" default="usa" />

Must work! i just tested in my grails 1.3.7 ! and it worked perfectly!

What is the version of grails that you re using?
