> the validate method of the Required validator contains following code line:
> if (value == null || value.toString().equals(""))...
> if the toString method returns null an exception will occur (happened to me accidentally
:)) 
> this code line should at least be changed to:
> if (value == null || "".equals(value.toString())... to prevent NPE
