I must remember that if I’ve using the Yahoo! (Yahoo User Interface) Datatable and the page validates and works in Firefox, but doesn’t work in Internet Explorer (IE), then the problem is most likely caused by an additional comma at the end of an array.
The YUI logger will not record any actions from that point on and no error will be reported by Microsoft Internet Explorer (at least not IE 6 or IE 7) – it’ll just stop the Javascript from working from the stray comma onwards.
Annoying!
