InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable (joint.min.js / line 47)

I am getting an "InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable" in joint.min.js @ line 47.

I am not very adept at javascript and am just trying to get the Org Chart jointJS demo to run.  

I cannot find any support documents on this issue so I am certain it is a noob mistake.  What am I missing?

It seems the code with the issue is as follows:

var e = this.node.getTransformToElement(b || this.node.ownerSVGElement);

Attaching my demo code and a Firefox debug screenshot.  Thanks!

Would it be possible to post the whole working demo including the scripts and stylesheets? It's much easier if we can just open it and see exactly what you see. Thanks!

Attached.

[dave]

which html file is your demo? How do I get to see the error? I tried opening all .html files but none of them produce the error. They're all blank pages.

org-demo.html.  The result of the error is that the page does not render.  If you use FireFox's dev tools you can see the actual error that I sent you the screen shot.

That demo is your own demo for the org chart.  I am simply trying to first get that demo to run from my web server.

Thanks.

Dave, jjs-demo.html is the only demo code that is working for me.  It's your basic demo that renders two blue connected boxes that say "My Box" inside of them.

Just need to figure out how to get org-demo.html to work.  At a loss at the moment.
