Hi,

nice post, just noticed a little mistake your MyDiffCallback constructor take in parameters newList then oldList. So instead of
new MyDiffCallback(this.persons, newList)
It should be:
new MyDiffCallback(newList, this.persons)

This little mistake that I copy pasted lead me to some unreadable stack trace ;)

Thanks
