ITicketChangeListener problem with trac 0.10.3, python 2.3

[francisco.lozano@…]

• Red Hat EL 4.0
• Trac 0.10.3
• Python 2.3
• SQLite
• Apache + mod_python

When you try to close a ticket with a TRAC environment and TimingAndEstimationPlugin, you get this:

Python Traceback

Traceback (most recent call last):

I don't know much about python so I don't know how interfaces work on it, but "TimeTrackingTicketObserver" implements the following method:

def ticket_changed(self, ticket, comment, author, old_values):

while in trac/ticket/api.py, in the ITicketChangeListener interface, you have:

def ticket_changed(ticket, comment, author, old_values):

[anonymous]

hmmm... the self in my version refers to the current instance of ITicketChangeListener (a component created by my plugin). I am not exactly sure what is going on here.

I seem to remember something about this interface changing, but cannot remember what it is. I am going to be pretty busy today, so I dont think I will be able to look into this today. However, I will try to look into it tomorrow and get back to you.

I'm very sorry, I thought I had upgraded, but no. I was using a really old version (0.1.5 maybe?). That version was using an older version of the interface, that didn't need the "author" param (I think). Upgrading solved it.

I'm sorry!

PD: Thanks for such a fast response!!! :)
