Ah thanks – it works fine now? Just a quick quick question regarding the callback. I have seen in some other examples that "this.patcher" has been used instead of "callback". Do you know the difference?
Legacy note: previous versions of the LiveAPI object required the jsthis object’s this.patcher property as the first argument. For backward-compatibility, this first argument is still supported, but is no longer necessary.
So if you don’t need a callback you can omit that parameter – I’ve just tested this and it works, but at one point this didn’t work and you needed to pass 2 parameters in (maybe something broke and is now fixed)
