That's exactly what I'm doing right now (a Tasks app + just load the minimum amount of data required for the list + load the full Task properties when entering the "DetailsView").

Isn't that what you suggested in your previous answer (when I was trying to get notifiable properties) ?
I'm confused (and also sorry, because I really guess it's a very trivial issue :( )

Ok, I'll keep that in mind, thanks :)

Thanks again...
