title: SignalR throwing JavaScript Error
body: <p>I'm new to signalr. I've started an MVC 4.0 application, out of the box, and wired up my signalr JavaScript on the Index View. When I click either the Register or Login buttons, signalr throws a JavaScript error. </p>
  
  <pre><code>Unhandled exception at line 11, column 10700 in http://localhost:49172/Scripts/jquery.signalR-   0.5.1.min.js
  
  0x800a138f - Microsoft JScript runtime error: Unable to set value of the property 'src': object is null or undefined
  </code></pre>
  
  <p>Any suggestions appreciated.</p>
  
  <p>EDIT: </p>
  
  <p>This is the extent of my code:</p>
  
  <pre><code>$(function () {    
      var blasht = $.connection.blashtHub;    
      blasht.addMessage = function (message) {
          $('#messages').append('&lt;li&gt;' + message + '');
      };     
  
      $("#blashtIt").click(function () {
          var control = $('#blashtText');
          var control2 = $('#hiddenUserId');
          // Call the chat method on the server  
          blasht.send(control2.val(), control.val());
          control.val('');
      });
  
      blasht.updateTopTen = function (message) {
          //add code to update the top user's list
      };
  
      // Start the connection   
      $.connection.hub.start();
  });
  </code></pre>
  
  <p>As suggested I dropped the min and here is where it is crashing, on the frame.sc = src; line.</p>
  
  <pre><code>reconnect: function (connection) {
      var that = this;
      window.setTimeout(function () {
      var frame = connection.frame,
      src = transportLogic.getUrl(connection, that.name, true) + "&amp;frameId=" + connection.frameId;
                 connection.log("Upating iframe src to '" + src + "'.");
                 frame.src = src;
              }, connection.reconnectDelay);
          },
  </code></pre>
  
  <p>SignalR, not me, is invoking this reconnect function. Obviously, that is how it maintains a connection with the server.</p>
