I looked into this a little while ago and as far as I could tell using the ListDataProvider prevents the loading indicator from ever being shown (long explanation which I never got round to writing up, but if there's interest I will do). The ListDataProvider is intended to be used when all of the data is resident in the client, if it isn't then you should use AsyncDataProvider.
