Robot stops working after a few minutes

[GoogleCodeExporter]

Hi,

I created a robot such that it was working perfectly. It basically responds
to specific user inputs. However, after it sits in a wave for a while, it
suddenly stops responding to commands and I could not find out why. (only
takes around 5 minutes for issue to surface).

The robot's address is dhamma-quote@appspot.com

Once you add the robot to the wave, it will tell you which commands it
listens to.

Source code also available.

ok, apparently the bot has amnesia problem. After a few minutes the quotes that 
were
read from text files and stored in ArrayList were all gone...

why?

i solved this by checking ArrayList size and if it's 0 I just re-populate... 
really
dunno why it's got amnesia.

This is not a Wave issue, it's part of the way App Engine works. It may serve
different instances of your robot to the same wave; you can't rely on 
population of
global variables. I'd suggest either using the datastore, memcache, or Wave
datadocuments for storage. Post in the group for more information on doing that.
