Hi Patrick,

That is one thing I want to check.. Thank you for the link !

I also ant to now if somenone else did change anything in the row as
saved in the database. I can achieve this by adding a serial field which
increases at every update, but hence, maybe DBIx::Class has something
for this too ;)
