I hate to "nag", but does anyone have any idea what's up with the bug
in the chat example I e-mailed about a while ago?
I've been playing around with the ask/answer functionality in the
interim, and (although it's quite possible that I'm missing something)
I can't get it to work at all. The first time I call ask it works as
I'd expect, but the second time it doesn't seem to have any effect
(the page remains as it was before calling ask). Which is consistent
with what I see in the chat example.
Does anyone have any examples of ask/answer other than the chat
example?
Of course, none of this stops me from being able to implement comet
functionality (and Lift is still the best framework I've come across
for this purpose, even without ask/answer). But being able to use ask/
answer would be nice :-)
