IndexOutOfBoundsException when Struts is populating and ActionForm with a List property

[Nestor Boscan <ne...@tcs.com.ve>]

Hi
 
I have an ActionForm class that has a List as a property. The ActionForm is
of type request. If I populate the ActionForm and show it in a JSP page it
shows correctly the values. But when I try to process the information that
is coming from the form Struts throws the following exception:
java.lang.IndexOutOfBoundsException: Index: 7, Size: 0
