Hi Matteo, Please make sure to cc the list, thanks...

A much better tact would be to make your application work under Zope 2.7.3. What prevents it from running under 2.7.3 now?

Hi chris the problem now is that yesterday night I installed ZWarehouse on Zope2.7.3b1 I reboot the server but I still have the same error!!! As you can see on the post below I followed your advice and installed Zope2.7.3 but no way to solve the problem...

But... but... this is fixed in 2.7.3. ;-) There's almost no way the same error could happen. Really. I've tested this. Lots. ;-)

Another strange thing is that after installing Zope2.7.3b1 Zwarehouse worked ok except for the fact that I could not see images of products saved on database( for my fault because I did not update the mysql driver) so this morning I restored the server to the situation of one week ago brutally (overwriting everything, copying from backup) and till now I cannot reproduce the error.

Does this mean you can or can't reproduce the error under 2.7.3?

Until yesterday I could reproduce the error waiting for a session to timeout and updating some page containing 'session=REQUEST.session' or a Zwarehouse script called setSessionOnRequest.py.

And what happened yesterday? It started to work?

I cannot understand... where are persistent data session containers? only in RAM or also in some temp folder on the system?

It depends where you have your session data container path set to in your /session_data_manager object. If it points to the object in /temp_folder/session_data_container, your session data is not persistent. If it points to a different session data container, your session data is persistent.

Right Now I'm running Zope2.6 on production system but I'm installing Zope2.7.3.b1 (downloaded from zope.org/download is that the right version should i have?) on another virtual machine trying to replicate the situation and the error because I'm sure that error will come soon again!

That's the right version. I'm so confused. Can we start over again? Here's what I'd like you to do: - please don't tell me any more about problems you have when you run under 2.6.X. I know that's broken. ;-) - please only tell me about problems that you have when you run your application under 2.7.3 b1 (not any other 2.7 version). - if you experience a problem using ZWarehouse under 2.7.3b1, please tell us about it in detail (including a traceback) no matter whether it does or doesn't have anything to do with sessions, so we know what you're trying to do and how it doesn't work. Thanks! - C
