    Description

      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.
