Subject: Re: [Zope] accessing session data error

Hi:
 
 Thanks for the rapid aswer of Chris McDonough. I will change the steps to replicate the error (sorry for the large steps before :( , I thinks that maybe was needful). Remember that the key of the error is the time interval between the request. If with 5 seconds don't appear the error try to vary to other, like 7 seconds. The 5 first steps are to create the situation and the sixth step are to provoke the error
 
Step 1: Create a folder called "reproducingError" in Zope Interface
Manage
 
Step 2: Create a srcipt "end" with the content:
"
# end script
idService = context.REQUEST.SESSION['idService']
return "Fin - " + idService
"
 
Step 3: Create a script "index_html" with the content:
"
# init script
sessionData = container.REQUEST.SESSION
sessionData.set("userId", "userExample")
return context.init2()
"
 
Step 4: Create a script "init2" with the content:
"
# init2 script
request = context.REQUEST
sessionData = request.SESSION
sessionData.set('idService', 'testService')
return context.external(context)
"
 
Step 5:create an external method called "external" in the "reproducingError" folder with the following content, in where the
function of the external method is "communicationResponse" and the module is any name that you give to the file:
"
# external method
import time
def communicationResponse(context):
    response = context.REQUEST.RESPONSE
    sessionData = context.REQUEST.SESSION
    strDetailEnd = "<script>window.location='reproducingError/end'</script>"
   
    for item in range(1, 40):
        time.sleep(3)
        response.write("Response iteration:" + str(item))
        response.flush()
    response.write(strDetailEnd)
    response.flush()
"
 
Step 6: open two explorer
In one of them call the object "reproducingError" (Example: localhost:8080/reproducingError), then wait 5 second and put in the other the same direction.
And wait the iterations....
 
Note: I count 5 second, not with chronometer. You can try with a near number.
 
Chris: I reproduce the error with the steps. I can't reduce it to an external method. Thanks again.
 
The error that I obtain is the same:
"
Traceback (innermost last):
  Module ZPublisher.Publish, line 101, in publish
  Module ZPublisher.mapply, line 88, in mapply

I must solve this, because this is part of my thesis for university graduation. Any help will be appreciated.
 
Thanks in advance,
