graphic.getShape() always return null

According to the ArcGIS Javascript API documentation for Graphic object, Graphic has a getShape() or getDojoShape() method, which:

Returns the Dojo gfx shape of the ESRI graphic.

graphic-amd | API Reference | ArcGIS API for JavaScript

 

It seems for older version of the Javascript API, it actuallly returns an object. However, in the newer version of Javascript API, it always return null for my point graphic object or polygon graphic object.

 

What I want to do is to implement a draggable marker, namely drag graphics point and drop at a new location using dojox.gfx.Moveable tool, something like:

 

var dojoShape = graphic.getDojoShape();   //or graphic.getShape();

var moveable = new dojox.gfx.Moveable(dojoShape);

 

//Update the geometry at the end of move 

var moveStopToken = dojo.connect(moveable, "onMoveStop", function(mover) { 

   // Get the transformation that was applied to  

  // the shape since the last move 

       var tx = dojoShape.getTransform(); 

      var startPoint = graphic.geometry; 

      var endPoint = map.toMap(map.toScreen(startPoint).offset(tx.dx, tx.dy)); 

     // clear out the transformation 

     dojoShape.setTransform(null); 

      // update the graphic geometry 

      graphic.setGeometry(endPoint); 

});

Hi Aaron,

Not sure where you are trying to access the dojo shape. The gfx object representing your graphic should be be created in the DOM before you can access it,

In the below fiddle, I'm using graphic-node-add event to identify if gfx DOM has been created.
