One question related to the A() callback.
Defining a <div id="some_id"> </div> and adding a target="some_id" to
the A works very well.
I tried to do session.flash/response.flash inside the callback
function but it didn't work. Is there a way to do it?
def callback_function():
it does some stuff...
if s == "1":
return something
elif s == "2":
return something else
else:
session.flash = "Message"
return ???
Is this possible???
