title: How to customize JSF conversion message 'must be a number consisting of one or more digits'?
body: <p>I have an input text that is mapped to a <code>Long</code> property.</p>
  
  <pre><code>private Long length;
  </code></pre>
  
  <p></p>
  
  <pre><code>&lt;h:inputText value="#{bean.length}" /&gt;
  </code></pre>
  
  <p>When I enter non-digits in that input text, I get the following conversion error:</p>
  
  <blockquote>
    <p>myForm:myField: 'someText' must be a number consisting of one or more digits. </p>
  </blockquote>
  
  <p>I was wondering how to customize this message to:</p>
  
  <blockquote>
    <p>length must be a number greater than zero.</p>
  </blockquote>
