title: regex validator, required field
body: <p>I'm trying to use the regular expression validator for a numeric ID field. The field needs to be a required field of any number. Currently, I'm using:</p>
  
  <pre><code>="\d{1,}"
  </code></pre>
  
  <p>Shouldn't this make it so the user has to at least enter 1 digit?? If I hit the submit button with the field empty, it passes validation and posts back.. But if I enter non-numeric characters, it errors fine. If I wanted zero or more occurrences, I'd use: <code>="(\d{1,})?"</code>
  <br/>
  Why isn't this working? Do I need to use this in combination with a Required Field Validator? That would suck >&lt;</p>
