So if I use a list attribute in my class to which I append I do need to, right?

Not necesarily, you can do this:

list = self.list

list.append(blah) ... self.list = list

The final assignment will be caught by the persistence machinery and your appends will be saved with it. If you look at the Catalog code, you'll see I did this all over the place and n'er once used commit().

Ah, useful trick -- code might be faster too due to avoiding variable lookups. Though in some cases commit() may be cleaner. I'll see what works best for me. Thanks! Martijn
