title: jquery checkbox array validation w/ formwizard
body: <p>I'm using the formwizard plugin and I can't get a checkbox array to validate. I've got other elements on the page working, but can't get this one (not to mention this is one of 2 checkbox arrays I'll need). There must be one or more items selected. I've chopped the page down to what I hope is essential for this question. </p>
  
  <pre><code>&lt;input type="checkbox" name="status_checkbox[]" id="status_professional" value="status_professional"&gt;
  </code></pre>
  
  <p>
  </p>
  
  <pre><code>    &lt;script type="text/javascript"&gt;
      $(function(){
          $("#infoForm").formwizard({ 
              formPluginEnabled: true,
              validationEnabled: true,
              validationOptions : {
                  rules: {
                      status_checkbox: {
                          //required: "input[name='status_checkbox[]']",
                          required: "input[name='status_checkbox:checked']",
                          minlength: 1
                      },
                  },
                  messages: {
                      status_checkbox: {
                          required: "Status field is required."
                      },
                  }
              },
              focusFirstInput : true,
          });
      });
  &lt;/script&gt;
