Script error when doing stuff in background thread

I have a grid that is displaying groups of items and images of those items. Since I need to do some processing before showing the images, I have put that in a background thread as described in this blog: http://jawsy.fi/blog/2012/10/20/advanced-zk-asynchronous-ui-updates-and-background-processing-part-2/ (Asynchronous UI updates and background processing)

When the user clicks an item, a window comes up showing some details and another image, which is also loaded in a background thread. The first time this works fine, but if the page is reloaded and an item is clicked I get a script error: "Failed to process script zk.cpsp is undefined (TypeError)".

The code in http://zkfiddle.org/sample/1cegh8e/2-Script-error-demo (this ZK Fiddle) will make the problem appear, but if you run it directly in Fiddle, then you will get the error "Failed to process script zkex is not defined (ReferenceError)" for some reason instead.

Can anyone tell me why this is happening? Thanks!
