Thanks for your email. Still could not get it to work. I probably
do not understand well how this thing (jquery/turbogear/cache)
supposed to work. I will dig into it further, any additional
suggestion is greatly appreciated. -tpn
My answers to your questions:
======================
(1) There is no particular reason to use local import, I need to clean up that.
(2) The call (load) works fine, as shown in the output, but the
replacement of "timetest" does not happen when "get time" is clicked.
I also modified the code to add a random number to the query such as
load("/time?sid=" + Math.random())... but does not help though.
Below are the sample code and the output (btw, I tried this on both
Firefox and IE, no difference). Also I did not see any difference
between using $('timetest') versus $('#timetest')
template:
