I've completely changed the way I was doing this now. Initially I
implemented lots of checks for NULL values, as Dan[2] recommended, and
this worked well apart from in the case of text areas. These broke
things completely. I've now decided to shove all form data into session
globals, and just refresh with a 'load_previous' flag in the URL. I my
form constructor sees this flag, it populates things from session
globals. Otherwise it resets the session globals with defaults.
This seems to be the best solution ( ie the only one that's worked
completely so far ).
Thank you, both of you. Long live Dans!
