At Connect 2014 the XPages team showed
the new infinite scroll feature for views in mobile apps. See the video
from Dario Chimisso and Tony McGuckin to see this feature in action.
Here is Dario's description:
"Infinite Scroll is a new feature
included in the extension library release as part of the OpenNTF
project. This XPages DataView feature takes a dojo scrollablePane and extends/enhances
it by adding automatic pre-fetching and fixed few issues, to have a solution
that works well with multiple dataviews and collapsible categories. The
InfiniteScroll feature improves and modernize the user experience when
dealing with long list of data. The data will be appended to the
scrolled list in a more natural way than the click and scroll experience
present with the "More" button.
When requests are issued to fetch more
data, a spinner will inform the user that some activity is going on under
the hood, while preventing further interaction until response is received,
avoiding multiple requests, this is particularly useful in presence of
a slow connection, or network latency. If no more data are available on
the server, the client will be notified and it wont issue more requests,
this is to avoid issuing useless requests that can have impact on the server
