Done: http://dev.laptop.org/ticket/11012
So far we have tested with with Write, but I'd expect similar results
with any other activity.

Hi Sridhar,
Simon is doing a lot of work in this area -- please do file this in
dev.l.o. The steps to repro are good, just add precise versions of the
OS and the affected activities.
cheers,

We have found a problem that could lead to data loss in the field.
General summary:
A shares an activity
B connects to A's shared instance
Collaborative work is done by A and B
A closes the activity
B continues to work on the activity (maybe they didn't realise
that A has left)
A shares again
B connects
Everything B has worked on since A left the first time is lost
This example uses the Write activity, but it can happen with any activity:
A begins activity
A types something (text is “AA” now)
A shares the activity
B joins activity
B types something (text is “AABB” now)
A closes activity (Text saved in A’s journal is AABB)
B continues to write something (text is “AABBCC” now)
B also closes activity (Text saved in B’s journal is AABBCC)
Now B opens the same activity from B’s journal. B is able to see
the text AABBCC now.
B closes the activity.
Now A opens the activity from journal. Text is AABB now.
A shares the activity again.
B joins the activity from the neighbourhood view since it is
shared. Text in B’s XO is AABB now.
A and B close the activity.
Now when B opens the activity from the journal again, only AABB is
seen (text CC is lost).
