The demo will not work if you change the flavor to "local". Tested in Safari, Firefox and Chrome.

Also Firefox crashes on the demo with the following errors: this is undefined [Break On This Error] this.Class = function(){}; class.js (line 17)

Class is not defined [Break On This Error] StorageEngine = Class.extend({ jquery.jstore.js (line 1027)

jStore is not defined [Break On This Error] }(jQuery, jStore));
