> I'm getting this error using groovy and JasperReports, when I use a field with a bean property that is a java.lang.Class.
> It seams that the implementation is not compatible:
> /** NOW IT IS LIKE THIS */
> {code}
>     public static Class castToClass(Object object) {
>         if (object==null) return null;
>         if (object instanceof Class) return (Class) object;
>         try {
>             return Class.forName(object.toString());
>         } catch (Exception e) {
>             throw new GroovyCastException(object, Class.class, e);
>         }
>     }
>     public static String castToString(Object object) {
>         if (object==null) return null;
>         if (object instanceof Class) return (String) object; // CLASS CAST IS HERE!
>         return object.toString();
>     }
> {code}
> /** I THINK IT SHOULD BE */
> {code}
>     public static String castToString(Object object) {
>         if (object==null) return null;
>         if (object instanceof Class) return ((Class)object).getName(); 
> /* 
> to be compatible with the reverse operation (castToClass) thats do Class.forName(), right? 
> */
>         return object.toString();
>     }
> {code}
> thanks, in advance!
