Thanks for your reply. I did see these messages and I'm ok with fixing the
iterate tag issue. I have a bigger (related) problem. My problem is when I
get a POST struts does not fill in my ActionForm correctly. For example, in
your example my LoginForm would not contain a beanArray with 3 elements. It
would contain 0. Struts is failing to generate the proper getter calls as
far as I can tell.

Please respond to

This issue has come up quite regularly in the list. I got round this by
taking my own copies of struts tags and modifying them so that they check
if
they are contained in an "IterateTag". If they are then I generate the name
appropriately using the property from the IterateTag, the current index
value and the property from the actual tag. Struts then automatically
populates the data back appropriately. You have to do something a bit more
complex if your using request rather than session scope to generate a bean
collection but thats the only issue.
For Example:
<logic:iterate id="list" name="formExample" property="beanArray">
<tr><td><html:text name="list" property="desc"/></td>
</logic:iterate>
generates:
<input type="text" name="beanArray[0].desc" value=".."/>
<input type="text" name="beanArray[1].desc" value=".."/>
<input type="text" name="beanArray[2].desc" value=".."/> etc. etc.
With my modified <iterate> and <text> (& BaseFieldTag) tags. This then
causes Struts to generate appropriate method calls to populate the values
back to the form [e.g. formExample.getBeanArray(0).setCode(..) etc.]
I detailed this a couple of times as a request but unfortunately so far no
one has given any feedback. Even if this proposal is no accepted then
putting the logic to generate the "name" attribute in separate methods
which
could be overriden rather than copying the tag and having to change the
doStartTag() method would be really useful.

P.S> I also have a similar issue where I want to overide the default
behaviour for setting the "value" attribute for another issue.
