ZeroClipboard JavaScript library throws Uncaught Error: Error calling method on NPObject

Question

I am trying to copy content to clipboard using https://github.com/zeroclipboard/ZeroClipboard. It seems a good library, but I am getting the error 'Error calling method on NPObject.' when the copy button (a flash) is hovered.

Seems like a flash security problem, but I am able to load the flash content.

Any ideas?

I got it work. It was a same origin security model breech. My web apps subdomain was 'WWW' but the flash content was served from 'CDN'. Just rendered both the contents from same subdomain.
