Subject: RE: Updating collections of information
I'm not sure I understand how I can override reset to solve this issue. Can
you elaborate? Do I have to create an empty collection or something?
To be clear, this is not the situation where checkboxes must be initialized
to false in the reset method. I've already fallen for that one. My issue
could simply be a collection of three beans which have String property
values "A", "B", "C" respectively (of course in real life the size of the
collection is not predetermined and the bean would have more properties).
These values are displayed using the logic:iterate tag and the html:text tag
(sample, untested code below). My form bean would have getBeanCollection()
and setBeanCollection(Collection c) methods. Each bean in the collection has
a getString() and setString(String s) methods. Assuming the user changes
the three values to "D", "E", "F", how should my action class retrieve the
new values? I'd like to call getBeanCollection() on the form bean and have
it return a collection of three beans in which the getString method returns
"D", "E", "F" respectively, but so far getBeanCollection() returns null.
<logic:iterate name="selectedBean" id="element" property="beanCollection"
type="xxx.yyy.ElementBean">
<tr>
<td align="left"><html:text name="element" property="string"/></td>
</tr>
</logic:iterate>
I appreciate your time and patience.

This is a classic question. You have to override reset in your form to
correctly populate all the elements.
