> list ui tag include select checkboxlist radio.
> typically we use a enum values as list for those tag
> {code:java}
> package biz.model;
> import com.opensymphony.xwork2.ActionContext;
> import com.opensymphony.xwork2.util.LocalizedTextUtil;
> public enum EmployeeType {
> 	PACKER, DELIVERYMAN, WAREHOUSEMAN , SALESMAN, MANAGER, SERVANT;
> 	public String getName() {
> 		return name();
> 	}
> 	public String getDisplayName() {
> 		return LocalizedTextUtil.findText(getClass(), name(), ActionContext
> 				.getContext().getLocale(), name(), null);
> 	}
> 	public static EmployeeType parse(String name) {
> 		if (name != null)
> 			for (EmployeeType en : values())
> 				if (name.equals(en.name()) || name.equals(en.getDisplayName()))
> 					return en;
> 		return null;
> 	}
> 	@Override  //sometimes we need override toString() to display nicely
> 	public String toString() {
> 		return getDisplayName();
> 	}
> }
> {code}
> {code:html}
> <@s.select name="employee.type" list="@biz.model.EmployeeType@values()" listKey="name"
listValue="displayName" headerKey="" headerValue=""/>
> {code}
> I override enum's toString use displayName replace name,so currently struts2 can't bind
data as selected
> solution:
> tag.contains(parameters.nameValue, itemKey)  -->  tag.contains(parameters.nameValue,
itemKey) || tag.contains(parameters.nameValue, itemValue)
