Here's my problem:
During a display of the page, I use:
<logic:iterate name="materialForm" property="substances" id="substances">
<tr>
<td class="table2"><html:text name="substances" property="casNumber"
styleClass="input1"/></td>
<td class="table2"><html:text name="substances"
property="substanceName" styleClass="input1"/></td>
</tr>
</logic:iterate>
But I also want to update the values.
The html then becomes:
<tr>
<td class="table2"><input type="text" name="casNumber"
value="14807-96-6" class="input1"></td>
<td class="table2"><input type="text" name="substanceName"
value="Talc" class="input1"></td>
</tr>
<tr>
<td class="table2"><input type="text" name="casNumber"
value="25068-12-6" class="input1"></td>
<td class="table2"><input type="text" name="substanceName"
value="Ethylene/styrene copolymer" class="input1"></td>
</tr>
<tr>
<td class="table2"><input type="text" name="casNumber"
value="63148-62-9" class="input1"></td>
<td class="table2"><input type="text" name="substanceName"
value="Polydimethyl siloxane" class="input1"></td>
</tr>
<tr>
<td class="table2"><input type="text" name="casNumber" value="9003-53-6"
class="input1"></td>
<td class="table2"><input type="text" name="substanceName"
value="Polystyrene" class="input1"></td>
</tr>
So now, the bean doesn't find any getSubstanaces(ArrayList), it only sees a
bunch
of casNumbers and substanceNames. If I say, getCasNumber() in the bean, it
only
gets the first one.
How do people deal with this in struts?

Subject: Re: getting a list in Action class
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.)
