validator not instanceof PageAware

[trostum]

Hey.
I am trying to figure out the springmodules and commons validator.

<pre>
 protected void validatePage(Object object, Errors errors, int currentPage) {
       Validator[] validators = getValidators();
       for (Validator validator : validators) {
           if (validator instanceof PageAware) {
               if (((PageAware) validator).getPage() == currentPage) {
                   validator.validate(object, errors);
               }
           }
       }
   }
</pre>

The validator is not an instanceof PageAware and therefore the validator will never run. Have i forgot to set some configurations?
