[google-appengine] Re: Channel use/reuse question
Hello Richard, I had the same problem and could only resolve it by generating a new token for the reconnecting user, i.e. calling create_channel again. You can use the same user id though. I believe I read in the docs somewhere that a token is only good for one sustained connection, afterwards it's discarded.

Hm, well this defeats the purpose because the point is to not cut into the rather low amount of channels GAE affords us daily. Can anyone from Google confirm that this is the case and the only way to do it is to call create_channel again?

Hi there. You've discovered a bug in the dev_appserver; this case should work fine in production and will be fixed in 1.5.1. If you feel like hacking a patch into the dev_appserver code, you can add this below line 244 of google_appengine/google/appengine/api/ channel/channel_service_stub.py (in the 'else' clause of 'if client_id in self._connected_channels' in connect_channel) 244 self._connected_channels.append(client_id) >>> self._channel_messages[client_id] = [] Hope that helps- -Moishe -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

*Thank you* Moishe. Problem solved - I was going batty, being convinced it was a problem with my code... - Ben On May 17, 9:06 am, Moishe wrote: > Hi there.
