      Description

      In the Click Extras project, the current EmailField validation does not sufficiently limit user input to the format of an email address. As an example, I loaded the Avoka examples site and was able to successfully submit the following as an email address in the Extra Form Controls page:

      how.can@this@be@a@valid.email.address

      For my own use I have extended EmailField with the following additional validation logic:

      private static final Pattern EMAIL_ADDRESS_REGEX_PATTERN = Pattern.compile("^[a-zA-Z0-9._%+-]@[a-zA-Z0-9.-]
      .[a-zA-Z]

      {2,4}

      $", Pattern.CASE_INSENSITIVE);
      ...

      @Override
      public void validate() {
      super.validate();
      if (EMAIL_ADDRESS_REGEX_PATTERN.matcher(StringUtils.trimToEmpty(this.value)).matches())

      { this.setErrorMessage("email-format-error"); }

      }
