Federico,
Glad to see you're actively working on James. I should be leaving for a
meeting now, but here are my quick 2 cents: My approach was designed on
the assumption that 90%-95% of the time, you're not making a significant
change to the email message (if any)... you're changing a header,
rerouting this message, etc... My approach was more a mail filter than
a request/response system (which I had trouble when I started
considering usages of this).
I *agree* it would be nice to support forking messages, but I never was
happy with anything that supported this approach because then most of
the time, it's a pain... do you have a Vector or array of response
messages? I'm thinking the best way we can do this is to offer a
convenient clone () method (either called directly on the Message object
or through the message queue handler). You could clone the message,
make whatever modifications to the new fork you want, and have it
properly go into the message queue in an identical situation as the
other. Reasonable?
