I forgot
to mention, the main idea with the cache was good, but
the data table seems
to ignore the parameter which should keep the
model in ram, so the whole
caching idea was pointless (but I left it in
in case it might work one
day)
But if you read the code I think you can get the clue on how
to
implement the needed stuff, all you have to do is to override some
of
the basic data model methods and add your needed functionality in
there.
