Hi all:</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">I
think that I found a ZOPE bug. Is really very important for me know what can
I do for avoid it. The first 9 steps are to recreate the situation and the
other steps are to provoke the error.</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 1: Crate a folder called "reproducingError" in Zope Interface
Manage</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 2: create a page template called "index_html" in the "reproducingError"
folder with the following content:<BR>"<BR><!-- index_html page template
--><BR><form name="form1" method="post"
action="reproducingError/init"><BR> <input type="text"
name="user"><BR> <input type="submit" name="Submit"
value="Submit"><BR></form><BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 3: create a python script called "init" in the "reproducingError"
folder with the following content:<BR>"<BR># init script<BR>sessionData =
container.REQUEST.SESSION<BR>sessionData.set("userId",
container.REQUEST.user)</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
return context.init2_html()<BR>"</DIV>

</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 4: create a page template called "init2_html" in the "reproducingError"
folder with the following content:<BR>"<BR><!-- init2_html page template
--><BR><a href="init2">passing face 2</a><BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 5: create a python script called "init2" in the "reproducingError"
folder with the following content:<BR>"<BR># init2 script<BR>request =
context.REQUEST<BR>sessionData = request.SESSION</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
sessionData.set('idService', 'testService')</DIV>

context.first()<BR>return context.external(context)<BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 6: create a page template called "first_html" in the "reproducingError"
folder with the following content:<BR>"<BR>First Response<BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 7: create a python script called "first" in the "reproducingError"
folder with the following content:<BR>"<BR># first script<BR>response =
container.REQUEST.RESPONSE<BR>str = container.first_html()<BR>
response.write(str)<BR>response.flush()<BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 8: 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:<BR>"<BR># external method<BR>import time</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
def communicationResponse(context):</DIV>

response = context.REQUEST.RESPONSE<BR>
sessionData = context.REQUEST.SESSION<BR> strDetailEnd =
"<script>window.location='reproducingError/end'</script>"<BR>
<BR> for item in range(1, 40):<BR>
time.sleep(3)<BR>
response.write("Response
iteration:" + str(item))<BR>
response.flush()</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
response.write(strDetailEnd)<BR>
response.flush()<BR>"</DIV>

</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 9: create a python script called "end" in the "reproducingError" folder
with the following content:<BR>"<BR># end script<BR>idService =
context.REQUEST.SESSION['idService']</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
return "Fin - " + idService<BR>"</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 10: open two explorer in wich call the object "reproducingError"
(Example: localhost:8080/reproducingError)</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 11: enter an example text in each one.</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Step 12: clink in the link of one of them, and 5 second later clink on the
link of the other explorer. The waiting for around 5 second is necesary
because with other time interval not allways get the error.</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
Stpe 13: and wait the "Response iteration"... Please if the error
don't appear in any of the pages, begins at Step 9 again. and try to count
to 5 witch other velocity :)</DIV>
<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">

<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: tahoma; BACKGROUND-COLOR: white">
The correct result is:<BR>"<BR>Fin - testService<BR>"</DIV>
