Ah, I see. Something like this interface that a model can optionally
implement:
public interface ModelLifetime
{
public void discard();
}
I have no objection to adding it, although be aware that this is
probably an anti-pattern... usually you want to have all your data
access completed by the time perform() returns.
Since the RC seems to be solid, we want to build the final release of
Maverick 2.0 RSN, probably tomorrow. I'll probably slip this change in
anyways since it doesn't require any refactoring.
Sound good?
BTW, if I'm slow to respond to mail, it's because I just started a short
contract at Maxis doing WebLogic development and they're keeping me
occupied. That, and I'm still couch-surfing, so I'm either busy or
don't have a stable net connection available :-)
