> If you have a List  in an Action that you want to maintain through a form I would expect that coding a s:hidden tag for the List would work.  
> Currently the s:hidden tag does represent the List in the generated HTML however when the form is submitted the parameter is not translated back into the List correctly.
> eg.
> If you have a List called "ids" which contains 4 Strings "22030", "6496",
> "6457", "6448" and 
> When the following tag is used:
> <s:hidden name="resend.ids" />
> It produces the following HTML:
> <input type="hidden" name="resend.ids" value="[22030, 6496, 6457, 6448]" id="/test/resend_resend_ids"/>
> When the form is submitted the "ids" List is populated with one String
> "[22030, 6496, 6457, 6448]" instead of 4 Strings "22030", "6496", "6457", "6448".
> This looks like XWorkBasicConverter needs some enhancing but I haven't figured out how.
> The only workarounds for this that I can see are:
> 1. Iterate through the List in the JSP and use a s:hidden for each element in the List.  This will generate a lot of unnecessary HTML.
> 2. Create a custom converter but I think that support for Lists should be out of the box.
