Well, lets keep up the momentum and try to reproduce Julian's firefox issue although i've never seen it. Has anyone else?

Yep that's the culprit for the promlem with IE10!

https://github.com/thexerteproject/xerteonlinetoolkits/commit/b0e4411c55a397
27d11003d0b6d9ed2ae8e57439

was:
<body onload="javascript:sort_display_settings()"  onselectstart="return
false;" onscroll="body_scroll()">

Currently in 2.1 branch:
<body onload="javascript:sort_display_settings()"  onselectstart="return
false;" onscroll="body_scroll()" onbeforeunload="javascript:logout()">

removing onbeforeunload="javascript:logout()" stops the problem with IE 10.

But I guess that leaves us with the Firefox issue you tried to fix with
that?

I might have added some ode to try and force the logout, to kill the session
for next time, so if you find that, it was me... I don't think it works. I
didn't think I'd checked it in though?

Hi Ron,

Well, further to your testing I was now able to reproduce the problem on
BrowserStack using IE10.

What I am seeing (hopefully you can confirm) is that when you click create
3x files load asynchronously and one of them is logout.php... (see
screenshot) but its not the same files as on the older sandpit install.

I'm not sure yet why it is loading that file though or indeed why it is not
doing it in other browsers but we're a step closer to locating the problem.
It must be in a recent change to the javascript though so at least its
closer to being tracked down.

Hi John/all
ok I've been testing further and there are too many variables to conclude
for sure but here's a summary...

Have been testing with 2.1 branch from git As far as I can tell there's
definitely a problem with IE 10 which in my case doesn't occur with IE 11 or
other browsers Have tested with two separate Windows 7 installs with IE 10
and can reproduce the problem with both IE10's and via xampp as well as an
online linux install the same installs work fine via IE 11 and also as
decribed previously earlier XOT code works fine with the same IE 10 I've
been testing the local xampp installs via guest auth and the online installs
via moodle so the authentication method doesn't seem important

If you have IE10 and access to the server we used previously for testing
updates you can test as follows:
1. Visit http://vle.jisctechdis.ac.uk/xot (latest 2.1 branch) try creating a
project you should get a session error?
2. Visit http://vle.jisctechdis.ac.uk/sandpit (earlier 2.1 branch) try
creating a project should work Other browsers should work fine on both
installs although curious as to whether Julian or anyone else gets session
errors with firefox?

Not sure if it's relevant or a problem just with the Win 7 via Parrallels I
was using on my Mac to test a second IE10 on a different pc but on that I
was also getting the following js error:

script16386: No such inteface supported

template_management.js, line182 character 7

As I say that may be a red herring but the error I can reproduce reliably
with latest 2.1 + IE10 but not previous 2.1 regardless of browser is:

Session ID not set

HTH

Its possible i suppose but i would have thought that it would kill all
sessions equally...

until we can reproduce it is going to be really hard to track down...

I know you WANT it to be related to the upload code ;-) but I doubt it is as
that is not touched after login until you actually edit and upload a media
file... Ron is seeing it in IE10 which I don't think is affected by the
Flash Cookie bug anyway...

Doesn't seem to be any commonality yet: Firefox and IE10, LDAP and Guest....

No, it's FF, and I'm fairly sure it's related to the stuff that changed

Ah well it looks like this was in the zipping code which preceded the new
code that Tom implemented recently, to remove some dependency...

Hmmm, we really need to get to the bottom of that session id problem. Does
it do it in every browser?

Yeah sorry the xyz... was just my representation of a series of numbers
followed by .zip

My test of the latest code was on xampp only. I'll test again but Julian has
also reported session id not set issues.

I've not really seen any session issues on a windows install and on xampp
mainly though. Have never seen the invalid templat id error either...

the example_zipper_new... file seems to be related to old export code
(https://code.google.com/p/xerteonlinetoolkits/source/browse/trunk/modules/x
erte/export.php?spec=svn696&r=696) with _xyz on the end nothing shows in
Google but remove _xyz and you get hits...

Never seen 'invalid template id'. But 'session ID not set' is doing my head
in.

I don't recognise 2.

Hi all
I think an issue I mentioned in the thread entitled testing results got lost
in the discussion about re-running setup so I'm checking again along with a
separate issue I've noticed.

Issue 1
I downloaded xertetoolkits_2.1 Version:2.1 Last update  2014-03-14 from the
community site and from my testing this revision is not reliable e.g. one
minute I can create an LO and the next minute I get one of two errors when
trying to create a new lo:
Session ID not set
or
Invalid template_id (could not find in DB)

Q. Does this not happen for others?

Issue 2
In an older revision that I've been using which seems to be relatively
trouble free I've noticed that one or more files named something like
example_zipper_new_xyz. is getting created and included in any successful
export but also still residing in the project folder on the server.

Q. Does anyone recognise this? Was it fixed in a later revision that doesn't
have the session issue above?

Cheers
Ron
