      String validateData(Object data, String language)

      Validates the specified data

      The validation implementation must return a string if it encounters an error. This string has to contain the error message that will be seen by the user. If the validation was successful, the method must return a null value, meaning that no error was found.

      Parameters:
      data - The data to be validated
      language - The language code of the error message. If not specified, the default language will be used. The default language can be set with the DEFAULT_LANGUAGE JBStrap parameter.
      Returns:
      The specified error message or null, if the validation found no errors.
