Hi John
yes I just tested with fiddler running and with the current 2.1 branch e.g. the /xot install and IE10 as you say logout.php is being called after clicking create but any other browser including IE11 it isn't and with the previous revision on the sandpit install it isn't in IE10 either.

I'll do some further testing tomorrow with my local xampp install to try to find the culprit js.

Cheers
Ron

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
Ron

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 around file uploads: at least that's when it first appeared,

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
