Subject RE: How to display both selected key and value of s:select
Date Mon, 24 Dec 2018 08:00:09 GMT
Hi Albert,

The simplest method can be something like this:

public class RegisterAction {
...
public Country getSelectedCountryObject() {
foreach (c in countryList) if(c.countryId==selectedCountry) return c;
}
...
}

<s:property value="selectedCountryObject.countryName" />

Thanks for using Struts.

Kind Regards.
