Hi Daniel,

> 1) Sequences TAB:
> - Learner icons don't show when they sit in a stop. This looks like a bug.

As you might have seen, we are redesigning the flash interfaces (starting with LAMS Author). I'll take note of this so we can include it.

> 2) Learners TAB (more serious)

> Out of 8 learners, only one is shown (Refresh Button doesn't work). But I can display individual graphs for each.
> This looks like a fairly serious bug. Maybe related to the previous one ?

No, I don't think this is related to the previous bug. I have ran a small test and I wasn't able to replicated in English or in French. I tried to change the name of the students to contain apostrophes (as we had a similar issue with this before) but that wasn't the case. Similarly with activities names containing apostrophes.

Also I tested with our Moodle integrated demo site and wasn't able to reproduce it.

Would you be able to send me the sequence you are using so we can run a test?

Login as sysadmin directly into LAMS. Go to the sysadmin menu, click on "Find User", search the name of the user you use in Moodle and you should be able to find it. Once you found it, click on "login as..." and now you are that user in LAMS (without having to login thru moodle). I assume this is what you want do to?

Thanks,

Ernie



Thanks,

Ok that's a good trick I forgot about :)
In fact, I needed this to change the interface of the Moodle teacher back to English. But results are the same. Can't see the Learners.

I attached the LAMS sequence zip here (there is nothing private about it). I just don't think it's good enough to be in the repository...

Btw can there be an interaction between multiple instances of the same sequence ? In Moodle I use it in two different courses and with different permissions for the same users. Sounds crazy but it's not :)
course A: Students are methodology crash course learners and have to DO the sequence like a normal LAMS student.
course B: Students are learning LAMS design and can play with the sequence as "teacher" ...

Anyhow, this is not an urgent problem for me. I still can access the same data by clicking on activities in the sequences tab.

Hi Daniel,

Thanks for the sequence.

I can confirm that this is indeed a problem. For some reason, even when the backend is sending the all the student data to flash, flash only displays the first row. I'll keep looking into this. I have raised a task for it:

http://bugs.lamsfoundation.org/browse/LDEV-2484

Thanks,

Ernie

Does that mean the dev version ?

This bug is still alive in LAMS 2.3.4 (March 5 dated files) that I installed 2-3 weeks ago. Only see a single user, i.e. probably the last one connected.

Hi Daniel,

Yes, this was fixed for 2.3.5 and 2.4 branches. Unfortunately, this fix didn't cut it for the 2.3.4. release.

However, if you want to use it, it shouldn't be too bad to add these two files as they are just flash files (.swf) fixes.

It requires a bit of a fiddle with files, but it will work no problems. I'll post the details shortly.

Thanks,

Ernie

Hi Daniel,

OK, so in order to patch this these are the steps... I was trying to use an animation for this but it kept crashing on my so I have to give up

1) Stop LAMS (and good idea to make a backup before doing any sort of upgrade)
2) go to your jboss-4.0.2/server/default/deploy/lams.ear folder and find the file called *lams-monitor.war*.
3) Copy this file to a temporary location (your desktop for instance).
4) Rename the file to lams-monitor.zip
5) Unzip the file.

In side this file you will find two files that need replacing:

lams_monitoring_library.swf
lams_monitoring.swf

So delete these two files.

Then go right click into these two links to download this file (Make sure you right-click and go "Save Link As.."):

• lams_monitor_library.swf
• lams_monitoring.swf

6) Save these two files within the folder in which you unzip the content lams-monitoring.zip
7) Zip all the content of the directory again... (make sure you don't zip the parent folder but instead the content within the folder!)
8) Rename the zip as lams-monitoring.war
9) Put it back in your boss-4.0.2/server/default/deploy/lams.ear folder

10) Delete these two folders (as the folders might contain the .swfs cached on them):

* jboss-4.0.2/server/default/work
* jboss-4.0.2/server/default/tmp

11) Restart LAMS and Voila!!

If you have any problems, please let me know.

Thanks,

Ernie

Thanks Ernie !

I have the suspicion that you work too much lately.
Click on lams_monitoring.swf in your post above.

Took me a while to figure out what the problem was, but despite being a non-programmer I usually win when it comes down to installing things :)

Got the right file from here:
http://lamscvs.melcoe.mq.edu.au:8060/fisheye/browse/~raw,r=1.249/lams/lams_monitoring/web/lams_monitoring.swf

1.249 raw
Created: 2010-05-03 20:10:53 +1000 (55 hours ago) | Author: mseaton | Changeset: MAIN:mseaton:20100503100946
LDEV-2556 LDEV-2557 Tooltip style and Workspace dialog /author info changes to HEAD.

... and our learners do show up now :)

PS:
* I find that Flash could at least whine a bit when someone tries to load an HTML file instead of an *.swf. All I got was LAMS/Flash loading screen stuck at 50%.
* Also your method of *.war surgery is way to complicated. Just take a real archiver like 7zip on a PC, open the *.war as is and drag the files into the *.war and you are done. No need to rename, dezip and so forth ....

- cheers ! Daniel

I wasn't sure if I had answer it correctly this before, probably because I understood something different last time

If what you are trying to do is to get LAMS sysadmin to get monitoring rights over the sequence you created thru your other user in Moodle. In LAMS, add the sysadmin user as a author/monitor/student to the Moodle-created course. Now in Moodle, go to the monitor link to the lesson, open it and click on "Edit Class". Find the sysadmin user in LAMS and just add him as monitor.

Thanks,

Ernie

Ok thanks :)

I forgot to add the admin as monitor on the Moodle side ...

Anyhow, also for the "normal" LAMS admin the view is same, i.e. in the learners tab (this time in English) I only can see a single learner, but can see time graphs for each learner etc.
