The problem is the method public void test(int ctyId) because it have a param int ctyid

JSF must say: javax.el.MethodNotFoundException

Change to public void test() remember that apply request values phase occurs before invoke application phase, so #{propinsiBacking.countryID} is already set when method is executed.
