Trying to get the length field of null will cause a NullPointerException. The correct code
should be:
>                             String[] parameterValuesArray = (String[]) parameterMap.get(name);
>                             if (parameterValuesArray != null &&
>                                 !"".equals(parameterValuesArray[0]) && parameterValuesArray[0]
!= null)
>                             {
>                                ...
>                             }
