[schooltool-dev] Re: Catching changes in SchoolTool

[Paul Carduner]

I would not be surprised is IObjectModifiedEvent events were not being
thrown every time a person is modified.  You would have to check the
schooltool source code for that.  As for figuring out exactly what was
changed, you could either update *all* the information all the time
(the easy way), or possibly compare the pre-modified and post-modified
object for changes.  I'm not sure exactly how the latter option would
work, but I think it has something to do with the ZODB?  I'm sure
schooltool folks can provide some better answers.
