Robert, in my experience with offline, you'll need to create a grid or listview containing all of the objects you'll need access to. I put it on my home page and then added the class "hide" to it so it wouldn't be visible to the end use. This gets the data loaded locally, and then I've been able to do retrieve data. That was back when the getSlice function existed - it seems to have been removed since. Perhaps get or fetch would work now if you add the grid.
