getGraphicsNode () returns with Null

Hi,

 

in my code the getGraphicsNode returns with null:

 

    GraphicsNode importedGraphicsNode = canvas.getUpdateManager()

                                          .getBridgeContext()

                                          .getGraphicsNode(train);

            

In which cases returns the getGraphicsNode() with null?

 

My train object is:

 

<g>

      <use xlink:href="#train-shape">

      <use xlink:href="#route-shape">

</g>

 

and the creation of this train element is done in the same UpdateManagerQueue thread as in the getGraphicsNode() call.

 

Thanks in advance,

Tamas

  In cases where the given DOM Element doesn't have associated
graphics.  Also if the document is not marked as DYNAMIC then
it will not maintain this relationship.

   Everything sounds right, so I suspect there is something
subtle that is wrong.
