jQuery 1.4 + IE7 + flot 0.6 + jsonp 1.0.4

jQuery 1.4 + IE7 + flot 0.6 + jsonp 1.0.4

  Hi - I've found this strange one using flot and jsonp. I get an error with JQuery 1.4 that I do not get with 1.3.2. The error occurs in IE7, but not in Firefox.

I'm using jsonp (http://jquery-jsonp.googlecode.com) to get graph data and flot (http://code.google.com/p/flot/) to render that data.

In IE7, I have a scenario where this works OK 

    
    
     
  1.  $.plot($("#chartDiv"), 
    2. 
     
  2. [{"lines":{"show":true},"data":[[1259625600000,5305],[1259712000000,6539]]}]  
    3. 
     
  3. );
    4. 
    

    

     

    

    

     But retrieving that same json data via ajax call cause a script error. I get an 
    

    

     error on line 465 of 
     http://code.jquery.com/jquery-latest.js  
    

    

     (Unexpected call to method or property access)
    

    

     

    

    

     
       
    
        
  1.  // Not own constructor property must be Object 
    2. 
        
  2. if ( obj.constructor 
    3. 
        
  3.  && !hasOwnProperty.call(obj, "constructor") 
    4. 
        
  4.  && !hasOwnProperty.call(obj.constructor.prototype, "isPrototypeOf") ) 
    5. 
        
  5. { 
    6. 
        
  6.  return false; 
    7. 
        
  7. }
    8. 
       

    

    

     

    

    

     This works fine in Firefox on both 1.3.2 and 1.4 versions of jQuery. I 
    

    

     have example code below (& attached) to reproduce (you'll need to download flot to run it)
    

    

     

    

    

     Should I open this as a bug in jQuery 1.4 ? Or could it be something in Flot 
    

    

     or jsonp that is just exposed by 1.4 release of jQuery.
