Validator problem with integers

[Brad Plies <br...@bulliondirect.com>]

Hi folks,

Using struts-RC2, when using Validator with a dependency
on "integer" validation, I have a problem with the validator
assuming that any integer starting with zero "0" is
necessarily octal.  In one example, I have a form where
people enter phone numbers.  Which is split up into 3 text
boxes.  Area code, 3 digits, last 4 digits.  A fairly common
way to break it up.

Here is the validation.xml entry for one such field:

<field
   property="dayPhone3"
   depends="required, integer, minlength, maxlength">
   <arg0 key="Daytime Phone box 3" resource="false"/>
   <arg1 name="minlength" key="${var:minlength}" resource="false"/>
   <arg2 name="maxlength" key="${var:maxlength}" resource="false"/>
   <var>
     <var-name>maxlength</var-name>
     <var-value>4</var-value>
   </var>
   <var>
     <var-name>minlength</var-name>
     <var-value>4</var-value>
   </var>
</field>

Numbers like "0897" will cause the "... must be an integer" message.
Obviously it is not a valid octal number, and I know that the format
of these numbers would appear as an attempt at an octal number.

How do you prevent octal interpretation but still ensure that
the field is numeric?  I'm being a tad lazy here, because I
know I could always write my own pluggable validator, but
I'd like to use what already exists if possible.

Hi Brad,

use mask instead of integer. That should do the job. Error message 
states, that the entry is invalid. BTW, arg1 has to be used both for 
minlength and maxlength since {1} is the argument in the error message.

I found that mask can solve nearly all validation problems if they are 
constrained to one field. If you have interdependent fields you still 
have to go back and implement ActionForm::validate.

<field property="dayPhone3" depends="required,mask,minlength,maxlength">
  <arg0 key="Daytime Phone box 3" resource="false"/>
  <arg1 name="minlength" key="${var:minlength}" resource="false" />
  <arg1 name="maxlength" key="${var:maxlength}" resource="false" />
    <var>
      <var-name>mask</var-name>
      <var-value>^[0-9]*$</var-value>
    </var>
    <var>
      <var-name>minlength</var-name>
      <var-value>4</var-value>
    </var>
    <var>
      <var-name>maxlength</var-name>
      <var-value>4</var-value>
    </var>
  </field>
