Nested elements and multidimensional arrays

Hi, everyone,

I am correctly using nested iterators to display what is essentially a
2-dimensional array.  I have an ArrayList of Groups (JavaBean) which has
a name and an ArrayList of Items (JavaBeans).

The nested tags successfully display the elements as:

	groups[0].item[0].value
	groups[0].item[1].value
	
	groups[1].item[0].value
	groups[1].item[1].value

	etc.


But I can't figure out how to set up my action mapping to automatically
perform the reconstruction of the 2-D array for me.


Here's an excerpt from my struts-config-xml..

<form-bean 
	name="preferencesForm" 	type="org.apache.struts.action.DynaActionForm">
        <form-property 
		name="configGroups" 		type="com.tobin.tdx.Group[]"/>
</form-bean>
.....
<action
	path="/savePreferences"
	type="com.tobin.tdx.PreferencesAction"
	scope="session"
	parameter="savePreferences"
	name="preferencesForm">
	<forward name="success" path="tdx.config.preferences"/>
</action>


Any ideas?

Thanks in advance!

Hi Chris, use lazylist from commons or do it yourself in the form reset. 
Automatic != possible
