Re: Using ArrayList instead of String[] properties

[Mark Lowe]

In the logic-el:iterate you defined the bean to scope with the id 
attribute, but then don't reference it in the form element

<html-el:checkbox name="acct" property="accounts" indexed="true" />

I'd consider not storing the formbeans in a map as you don't need to 
get the values out with a key. I provided an example of how to do this 
in this thread even making an arrayList of dynaactionforms will work.

Apparently you don't have to use
logic-el:iterate with html-el:checkbox & indexed="true".  This works:
<c:forEach items="${accountMap[accountForm.map.calendarYear]}"
var="account" >
     <html-el:checkbox property="accounts" indexed="true">
I lied, that doesn't work at all.  It produces HTML like this:

  <input type="checkbox"
name="org.apache.struts.taglib.html.BEAN[0].accounts"
value="on">10_U_FADA0001
I read that indexed properties only work with logic:iterate, so I'm
trying to change over from logic:forEach.  Can someone help me sort 
this
out?

This works to generate HTML, but BeanUtils can't populate the ArrayList
that is the 'accounts' property of accountForm because the bracketed []
indexes are missing.
<logic-el:iterate
collection="${accountMap[accountForm.map.calendarYear]}"
                  id="acct"
                  indexId="ctr">
     <html-el:checkbox property="accounts" >
        <c:out value="${acct.key}"/>
     </html-el:checkbox>
     ...
However, if I add indexed="true" like so:

<logic-el:iterate
collection="${accountMap[accountForm.map.calendarYear]}" id="acct"
indexId="ctr">
     <html-el:checkbox property="accounts" indexed="true">
        <c:out value="${acct.key}"/>
     </html-el:checkbox>
It renders this HTML:
     <input type="checkbox"
name="org.apache.struts.taglib.html.BEAN[0].accounts"
value="on">10_U_FADA0001
??! This is my first attempt at indexed properties, which apparently I
need in order to use an ArrayList.  (The items in the ArrayList are 
just
Strings, not complex objects.  This isn't nested properties, it's just 
a
bunch of checkboxes.  I'm trying to use ArrayList instead of String[] 
to
avoid out of bounds errors.  String[] was working *fine* last week,
until I got the bright idea to use ArrayList.)

I'm getting the feeling that the things in the ArrayList property of 
the
form have to be complex objects and not just Strings.
