I never did figure out how to fix the exception I was getting, but I found
an alternate implementation that works. However, my business logic is built
on ArrayList and I didn't want to change that. Thanks to the magic of
getters and setters, I was able to do both:
-----
Form snippet:
private ArrayList items;
public Object getItems(int index) { return items.get(index); }
public Object[] getItems() { return items.toArray(); }
public void setItems(int index, Object item) { items.set(index, item); }
public void setItems(Object[] items) { }
public ArrayList getItemlist() { return items; }
public void setItemlist(ArrayList items) { this.items = items; }
-----
I noticed that setItems() is never called so I never bothered to implement
it. Everything is now working fine.
Thanks for your time.
Wiebe

<nested:iterate property="items"

IndexOutOfBoundsException: Index: 0, Size: 0

private Collection items; <--- null

Initializing "items" might help.
