sorry for the delay,
here is what i came up, but not sure if this is the best solution.

i've noticed a strange problem and perhaps you could take a look at that:
when i switch the list to different sorting e.g. "by rating" the trips
disappear (i'm sure this is expected). but when i select all dives
(see attachment XML) and then click  "delete dives", some of them are
left out. this is mainly because i have a check if get_dive() returns
NULL in delete_single_dive(). as far as i understand, it shouldn't
return NULL. the same problem is absent when deleting all dives with
sorting "by date" enabled.

another problem is that the trips' "when" flags are not updated if we
delete dives when viewing dives sorted "by rating" and then returning
back to the "by date" sorting. i don't think update_trip_timestamp()
is optimal for this, since it takes an iterator for a parent (trip
iterator) that does not exist when we are not sorting "by date".

a question here i guess is: should the trips ever disappear if we sort
by something other than date ?
