Hi, just a quick question.
I have a class that has 4 fields. 2 Strings, 1 int, 1 boolean.  I shall
refer to this class as MyClass
In my Action class I have a List (call it MyList) that is a list of  
MyClass.
It can be populated with as little as 1 item or as many as say 256 items
(could be more but I'll keep this limit for simplicity).
Iterating through MyList in a JSP with the struts tag
<s:iterator........</s:iterator> is easy enough. My question is this....

When I iterate through MyList in the JSP I'm setting form fields (of all  
4
fields from MyClass).  What would be the best way to get all that input  
back
when I submit the form?
Is there an example of this somewhere I haven't found or just a pretty
straightforward way of doing this I'm not thinking of?

Thanks,
Craig

You just need to tell struts what type of objects are in the list:

http://struts.apache.org/2.0.8/docs/type-conversion.html

Basically this would involve a "Myaction-conversion.properties" file  
alongside the action class. It would contain:

Element_MyList=mypackage.MyClass

Also, there's a pretty good section on this in "Struts in Action".
