[Nested Tags] Please help to confirm a problem..

[Je...@nlgroup.ca]

I am running on Struts 1.1b2 and Tomcat 4.04

I have provided a self contained JSP page that defines two objects and creates a list of lists and iterates though them three ways.
first by standard java, then logic:iterate tags and finally with nested tags.
My preference would be to use the nested tag version.
As near as I can tell, what I am doing is the same as many of the examples on Arrons site http://www.keyboardmonkey.com/
The only difference is a property that accesses an internal Map.  It seems to work well until the nested tags are used.

It my test the nested tags read all correct properties for the root object but when the child objects are accessed,the properties
are called on the root and not the current object as I would expect.

My Request:
Could someone please drop the JSP code into a test page and run it.
Observe the System.out from the wrapper object as well.
I would like to find out if there is a bug or that I am just a nut.

Thanks alot.
I need to decide on a direction for the remainder of our project, and would love to use the nested as much as possible.

PS:
A common requirement in our project to work with lists of lists.
many times each list has header information such as subtotal ect.

I am trying to use a generic wrapper that contains one internal List and a single getHeaderItem(headerName) property that will provide the specific.
My goal is to have my business delegate methods return this generic wrapper (or wrapper of wrappers) and keep the business structure out of the
actions ect
