I have this stage associated to a container:

html:

<div id="container">

script 1:

var stageInFirstScript = new Kinetic.Stage({
    container: document.getElementById('container'),
    width: this.SKETCH_WIDTH,
    height: this.SKETCH_HEIGTH
});

In a second script, I need to manipulate the shapes on the stage I just created. Is it possible to retrieve stageInFirstScript with something like this?

script 2:

var stageInSecondScript = document.getElementById('container').RetrieveExistingStage();
//now I have retrieved stageInFirstScript
//I can add shapes to it, etc....

Any help or alternative solution would be appreciated!
