this.country = getCountryParam(fc);
return "result";
}
public String outcome1()
{
FacesContext fc1 = FacesContext.getCurrentInstance();
this.lastname = getlastnameParam(fc1);
return "result";
}
//get value from "f:param"
public String getCountryParam(FacesContext fc){
Map<String,String> params = fc.getExternalContext().getRequestParameterMap();
return params.get("country");
}
public String getlastnameParam(FacesContext fc1)
{
Map<String,String> params = fc1.getExternalContext().getRequestParameterMap();
return params.get("lastname");

xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ice="http://www.icesoft.com/icefaces/component"
xmlns:icecore="http://www.icefaces.org/icefaces/core"
