First Entry of the First Iterator
Second Entry of the First Iterator
Third Entry of the First Iterator
First Entry of the Second Iterator
Second Entry of the Second Iterator
Third Entry of the Second Iterator
First Entry of the Third Iterator
Second Entry of the Third Iterator
Third Entry of the Third ITerator

Parameters

Name	Required	Default	Evaluated	Type	Description
id	false		true	String	The id of which if supplied will have the resultant appended iterator stored under in the stack's context

Example

public class AppendIteratorTagAction extends ActionSupport {

 private List myList1;
 private List myList2;
 private List myList3;


 public String execute() throws Exception {

     myList1 = new ArrayList();
     myList1.add("1");
     myList1.add("2");
     myList1.add("3");

     myList2 = new ArrayList();
     myList2.add("a");
     myList2.add("b");
     myList2.add("c");

     myList3 = new ArrayList();
     myList3.add("A");
     myList3.add("B");
     myList3.add("C");

     return "done";
 }

 public List getMyList1() { return myList1; }
 public List getMyList2() { return myList2; }
 public List getMyList3() { return myList3; }
