+ === 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>
