this is what i have:

You have missed the listKey attribute. If you change it as:

<s:combobox label="Country" name="country" headerValue="Select" headerKey="1"
list="%{countries}" listValue="name" listKey="id"/>

It will probably work.

See http://struts.apache.org/2.0.14/docs/combobox.html for all the attributes available.
