My attempt to implement jQuery UI dialog in JSFiddle has been unsuccessful, consistently resulting in a dialog opening error caused by a deep-seated issue within jQuery UI:
Uncaught TypeError: Cannot read property '3' of undefined
.
Although I am utilizing jQuery UI 1.8.20, switching to a different version such as 1.7.1 resolves the problem. To illustrate this issue, I have prepared a fiddle. Simply click the 'Click me!' button and observe the TypeError notification in your browser's console (e.g. Chrome's developer tools).
What is the root cause of this problem? Could it be an incompatibility between jQuery UI 1.8.20 and JSFiddle?
