--> Whats new
"Although not removed, in many cases you should replace the deprecated
ActionErrors with the preferred ActionMessages to ensure correct
operation."
reason is ActionErroR is deprecated...
ActionErrorS can't
--> validate() returns that guy. so with ActionMessages in validate()
there is no backward-compatibility

> Had installed Struts 1.2.1 on the local machine and
> everything runs smoothly ... except for my Struts 1.1 custom

>
> Previously, the method signature in the validator was:
> "public static boolean validateFromToDate(Object bean,
> ValidatorAction va, Field field, ActionErrors oErrors,
> HttpServletRequest request)"
>
> Inside the method, when validation fails, a call to oErrors
> would throw a NullPointerException.
> "oErrors.add (field.getKey (), Resources.getActionError
> (request, va,
> field));
>
> Changing the method signature would resolve the NPE:
> "public static boolean validateFromToDate(Object bean,
> ValidatorAction va, Field field, ActionMessages oErrors,
> HttpServletRequest request)"
>
> Has anyone encountered this issue?

> Besides this, all seems to be well (so far)!
