getting a list in Action class

["Domen, Ken" <Ke...@nike.com>]

If my jsp has the following:

<logic:iterate name="materialConfirmationForm" property="substances"
id="substanceBean">
<tr>
    <td class="table2"><html:text name="substanceBean" property="casNumber"
styleClass="input1"/></td>
	<td class="table2"><html:text name="substanceBean"
property="substanceName" styleClass="input1"/></td>
</tr>
</logic:iterate>

Why won't my receiving Action class get these elements with:

ArrayList list = myForm.getSubstances();
Iterator i = list.iterator();
while (i.hasNext())
{
        Substance s = (Substance)i.next();
        System.out.println("s.getCasNumber(): " + s.getCasNumber());
}

tricky!
does
   myForm.getSubstances();
return a list? is it the correct size?
I would have thought putting enough debug messages would highlight the problem.
I'd guess it's not even executing your debug code because you'd get a null
pointer exception from list.iterator() if the list was missing & CalssCastExp
if you got the wrong list. 
Intriguing! (Most likely something really obvious... bit I can't see it.)
