      Description

      It seems to me we could leverage the existing component event hierarchy to allow for tightly customized input translation and parsing.

      I would propose three component events:

      "toclient" : corresponds to Translator.toClient(). Passed an object as the context (possibly null), result must be a String.

      "parseclient": corresponds to Translator.parseClient(). Passed a string as the context, returns an object or throws ValidationException.

      "validate": corresponds to Validator.validateInput(). Passed an object (provided by the translator). No return value. May throw ValidationException.

      We'll have to come up with a better mechanism for allowing event handler methods to throw an exception. Currently, I suspect, that you would get Javassist compile errors if you try!
