Hello,

you can not define the ArrayList like you did it. You have to define like
this:


The collection to be iterated over MUST conform to one of the following
requirements in order for iteration to be successful:

 - An array of Java objects or primitives.
 - An implementation of java.util.Collection, including ArrayList and
 Vector.
 - An implementation of java.util.Enumeration.
 - An implementation of java.util.Iterator.
 - An implementation of java.util.Map, including HashMap, Hashtable,
 and TreeMap. *NOTE* - See below for additional information about
 accessing Maps.

So you have to define a Collection instead of an ArrayList. I hope this help
you,

Eider
