Answer 1

Try to add get and set method for our field departmentlist,in your class Exple : in your class controller put this method for your field departmentlist :

public  List<String> getDepartmentlist(){
  return this.departmentlist();
}

public void setDepartmentlist(List<String> departmentlist){
  return this.departmentlist = departmentlist;
}

Answer 2

The error

"The requested list key 'departmentlist' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location] "

means that the select tag is not able to resolve departmentlist as a collection. It is an OGNL expression which is trying to find the departmentlist in the value stack and if it not found or contains a null reference the select tag will complain. When you render the select tag make sure the list is in the value stack and is initialized. See the example here.
