title: Add enum to spring webflow
body: <p>I want to include an enum </p>
  
  <pre><code>public enum ContactType {
      PHONE,
      FAX,
      MAIL
  }
  </code></pre>
  
  <p>to my <code>flow.xml</code> to have access in the views and also in the flow itself. I tried to add it as a var (like bean):</p>
  
  <pre><code>&lt;var name="ContactType" class="my.package.common.util.ContactType"/&gt;
  </code></pre>
  
  <p>But I get the error:</p>
  
  <pre><code>NoSuchMethodException: my.package.common.util.ContactType.&lt;init&gt;()
  </code></pre>
  
  <p>Should I <code>init()</code> the enum in some way? or maybe there is another way to include it?</p>
