What else do you need?
If you add your own field into the html form in ticket.html - this field won't appear in `old_values` even if it is named the same. I also expected it to appear there, but Trac logic filters incoming data to contain only fields known to core ticket system.

It is a tutorial for people who will be extending and maintaining Trac after me 2. They already feel uneasy about abundance of options Trac provides 3. They'd like to keep features modular - one file, one feature, no config unless ABSOLUTELY necessary 4. They'd like to add fields to other Trac forms as well (hidden or not), that's why I'd like to show a universal solution 5. I might have a desire to dance on the bones of Trac architecture =) > I > recommend to use CustomFieldAdminPlugin [1], if it is too hard for you > to study correct syntax for [ticket-custom] section. It is hard for me to write Trac plugins - much harder than I'd expect from such awesome product. -- anatoly t. -- You received this message because you are subscribed to the Google Groups "Trac Development" group.
