As I see, the problem is that ajax request (may be not ajax only) didn't wait for closing session file by another one and read/save data from/to it at any time! Lock did not work on my Win7 because , as I think, for Win it's one process. Request processing may be not pure parallel but fully asy

All responses within the same session are supposed to have the same session_id. The fact that all three Ajax requests can access the session doesn't necessarily mean they are being processed in parallel (the requests might still be completing one after another). It would be helpful if you could

Does the problem occur only on the first page load of the session? If so, does the problem go away if you add the following line at the top of the many_ajx_form function: session.dummy_data = 'dummy data' If that's the case, then this is the same problem diagnosed in the original thread, w

I may be missing something, but I still don't see where sale_order_checkout touches the session (it has a form in the HTML, but it is not a web2py form with a _formkey token, so it doesn't use the session). I don't think your problem is the same as the one discussed in this thread. Which of the

Did you leave out some code, because the code you have shown for sale_order_checkout includes no form nor any writing to the session? The idea of the dummy data is just to write some nonsense data to the session in the *parent* function: def sale_order(): session.dummy = 'dummy data' ..

Thanks Niphlod & Anthony - I'm glad we finally got to the bottom of this. I thought I was going crazy for a while there! In the short term, I'll use Niphlod's trick of setting a dummy session variable to make sure the session is saved to disk. In the medium term, I vote for option 1 (always sa

The problem is that we made a change so that no session file is created at all if this is a new session and the session remains empty. So, when the index page is requested, no session file is created. Next, the form1 Ajax request comes in, and because there is no session file, there is nothing t

umpf I can't understand why this is not working "ok". The problem lies indeed in the fact that one ajax request overwrites the session, if the session file is not there yet. I can only guess that the logic is failing to acquire a lock before creating the (new) file If a request has

If you are saving sessions in files, the session file should be locked by each request, so there shouldn't be any race conditions. However, if you are saving sessions in the db, you could get race conditions (e.g., both Ajax requests read the same empty session, then form1 saves its session wit

Good thought, but that doesn't seem to be a factor since it works in incognito after the first submit, and I can reproduce in regular mode. For some reason, on initial page load it is not saving both formkeys. Is it possible that there is a conflict when saving the the sessions file? i.e. both

A little more progress - I can now predict when the problem will occur server side, before hitting submit. This is what I do: 1) clear all my web2py session files 2) open an incognito brower 3) go to the page with multiple ajax forms 4) take a look at the new session file. If it looks like this:

Not sure what's going on. In the browser, maybe use the developer tools to confirm what is being sent (i.e., session cookie, value of the hidden _formkey field). On the server, check that there is a "_formkey[formname1]" key in the session and that it matches the _formkey value submitted with t

Probably both forms have the same formname, either because they are both based on the same DAL table or because they are both SQLFORM.factory forms. To avoid the problem, assign unique formnames to each via .process(formname='myform1'), etc. This is discussed in the book: http://web2py.com/book
