title: jsPlumb is not defined
body: <p>I'm working with jsPlumb where I'm getting an error "jsPlumb is not defined". This is some of my code:</p>
  
  <pre><code>   &lt;script type="text/javascript"&gt;
         $(document).ready(function() {
             ;(function() {
                 jsPlumb.ready(function() {
                     var instance = jsPlumb.getInstance({
                     //My code...
                     });   
                 });      
             })();      
         });
      &lt;/script&gt;
  </code></pre>
  
  <p>I think this error is because jsPlumb instance is in document.ready function 
  I get the error occasionally.</p>
  
  <p>Thanks for your help</p>
