New page:
=== Comparison using nested tag vs JSTL for nested objects on form ===

Many think that you are required to display nested data using the Nested tag. I agree the Nested tag is the cleaner solution, but just so you are aware you can do this with JSTL as well. (Below assumes JSP2.0)

companyForm has a List of divisions and for each division in the list there is a list of department objects and we will display the 'name' of each department.

''JSTL Solution''
{{{
<c:forEach items="${companyForm.divisions}" var="division" varStatus="divstatus">
    Division: <html:text property="divisions[${divstatus.index}].name" value="${division.name}" /><br>
    <c:forEach items="${division.departments}" var="department" varStatus="depstatus">
    --- Department: <html:text property="divisions[${divstatus.index}].departments[${depstatus.index}].name" value="${department.name}" /><br>
    </c:forEach>
</c:forEach>
}}}

''Nested Tag Solution''
{{{
<nested:root name="companyForm">
  <nested:iterate property="divisions">
    Division: <nested:text property="name" /><br>
        <nested:iterate property="departments">
        --- Department: <nested:text property="name" /><br>
        </nested:iterate>
  </nested:iterate>
</nested:root>
}}}
