2 deep nested forms (solution to 2 dimensional arrays with struts html tags)

[Mark Lowe]

A question came up the other week/month where someone nesting 2 deep 
and was trying to use a 2 dimesional array. I had the some problem 
today and had my chance to combine indexed and mapped properties to 
solve the problem.

I want to create a Restaurant Menu editor. So a menu has a few 
properties like title and start and end dates for seasonal menus.

So I have 3 action form or nested pojo's
MenuForm
CourseForm
DishBean
I used lazyMap and lazyList to save scoping to session.
MenuForm - has a lazyList or nested courses.
CourseForm - has a lazyMap of dishes and a getKeys() method that 
returns map.keySet().toArray()

and dishes are just plain string properties.
public DishBean getDish(String key)
public void setDish(String key,DishBean dish)
The jsp stuff looks something like this.
<html:text property="title" />
<c:forEach var="course" items="${menuForm.courses}">
	<html:text name="course" property="title" indexed="true" />
	
	<c:forEach var="key" items="${course.keys}">
		<html:text name="course" property="dish(${key}).name" indexed="true" 
/>
	</c:forEach>

</c:forEach>
its not quite as tidy as 2 dimensional array support, but it pretty 
clean looking.
