> Struts <s:checkbox> is not converted correctly to List<Integer> when only
one checkbox element is present and checkbox is not checked.
> [Given]
> 1) Mapping s:checkbox to a List<Integer>
> 2) there is only one checkbox in the list
> 3) the checkbox is not checked when the form is submitted.  
> [Result]
> Input invalid
> The issue is caused by the checkbox tag using the "submit unchecked values" design pattern.
 As a result, the code base tries to convert the value of the single unchecked element to
false (rather than not setting any value of the List<Integer>).
> Fix: Allow the developer to choose if the "submit unchecked values" is to be implemented.
 Add a new parameter to the s:checkbox tag ("requiredValue").  Default of requiredValue=true
for backwards compatibility.  When set to false, no hidden input values will be displayed
in the view.  This flexibility might be needed in other scenarios as well.
