Think that the answer you're looking for, is that your tags aren't quite
set up properly. There's work around of a work around. The child tags
need to work of the bean that is the current object returned from the
iterate tag, which is why the properties wont work. They also need to
get the index from the iterate tag.
1) To get the bean from the iterate tag, you need to set an "id"
attribute, (you did that, but weren't using it. Almost there :)
2) To get the properties working, the child tags need to address this
bean in the name attribute.
3) To get the indexing, the child tags need to be told they're indexed
with indexed="true"
For Example...
<logic:iterate id="rowBean" name="histLstForm" property="myListProperty">
<tr>
<td><bean:write name="rowBean" property="question" indexed="true"/></td>
<td><bean:write name="rowBean" property="ans" indexed="true"/></td>
<td><bean:write name="rowBean" property="dateCont" indexed="true"/></td>
<td><bean:write name="rowBean" property="typ" indexed="true"/></td>
<td><bean:write name="rowBean" property="cost" indexed="true"/></td>
</tr>
</logic:iterate>
...personally, it's a whole lot of mess to have to account for. If
you're using Struts 1.1b, you already have access to the nested tags,
which look after each other in a much easier way. No need for special
beans or indexed="true" properties. Here's the same thing with nested
tags...
Example...
<nested:iterate property="myListProperty">
<tr>
<td><nested:write property="question"/></td>
<td><nested:write property="ans" /></td>
<td><nested:write property="dateCont"/></td>
<td><nested:write property="typ" /></td>
<td><nested:write property="cost" /></td>
</tr>
</nested:iterate>
...a little easier, because the reference to the current tag is supplied
by the parent tag. So, the child tags will get the index, mapped
property, or whatever. And if you're on Struts 1.0/1.0.1 then you can
get the tags and tutorials and such from http://www.keyboardmonkey.com/next
Anyways, one of these should get you working again.
