[rt-users] Custom Fields Transactions

[Carlos Silva]

Hi all,

I'm trying to write a scrip to run with every transaction on tickets,
but I only want it to really do what it's supposed to do when one or two
custom fields change. My question is :

How can I see the old and new value of a ticket custom field on a
transaction object so that I can do it during the prepare stage?

Thanks in advance,
Carlos Silva
