I have found a workaround from the following post in the archive. http://www.nabble.com/How-to-inherit-or-have-a-dynamic-validate-to18127873.html#a18139604
Instead of passing something like required,min=0 as a FieldValidator to my component, I need to pass it as a String and create the corresponding FieldValidator in my component java class. FieldValidatorDefaultSourceImpl.createDefaultValidator has the code to create a Validator. It would be so much easier and logical to pass in required,min=0 as a FieldValidator from a Page class to the component, without the component having to implement the Field interface.
