Hi,
I'm frequently coming across a problem with the transaction. A typical
traceback is included below.
Relevant section of paste.ini:
[pipeline:main]
pipeline =
responselogger
browserid
deliverance
beaker
egg:repoze.tm2#tm
who
myapp
I don't call session.commit() anywhere in my code. And on refresh the
error disappears (usually the first refresh, sometimes on second or
third refresh).
Has anyone else come across this problem and if so what was the
solution or source of the problem?
Thanks in advance,
Darryl Cousins
