[TYPO3-dev] Fields in the TCA that does not exist in the DB

Hey Mads,

There are some hooks in tcemain that will let you unset your
non-database field before its actually saved.  Something like the
processDatamap_postProcessFieldArray hook is probably what you want,
since that runs just before the database call and gives you an array
of all the fields on the form.

Hope that helps....and looking forward to your seeing your category
work :)

THanks,
Jeff
