Create a new Valiation Rule

Hi,

I'm trying to create a new Validation Rule, but couldn't figure out how to
get the field value back as an Object instead of a String.

I created the validation method as:

public static boolean validateImageInfo(
     Object bean,
     ValidatorAction va,
     Field field,
     ActionErrors errors,
     HttpServletRequest request,
     ServletContext application) {

     String value = ValidatorUtils.getValueAsString(bean, field.getProperty
());

     ....

 }

but what I really what is getting an Object back (FormFile), instead of
String. I went through the org.apache.commons.validator.*, but couldn't
find any method that accomplishes this. Anyone has any idea? Is this even
possible?

Thanks,

Changyi

So casting didn't work for you?

Maybe you are trying to do too much in the validateImageInfo() method.   I view
it as a yes or no validation.  For more complex businese-rule validation, I
would override the validate() method in the Form class instead.  That way, you
can access the bean object.

Hope this helps.
