Chamilo-lms: Report Errors - lp progress and exercises on course report

[marshel]

Current behavior / Resultado actual / Résultat actuel

The report gives wrong info on progress and exercise as follows:

EXERCISE ISSUES:
The user has 2 exercises with 100% on both. The report show the promedio as 67%.
On the student frontend, it is show on the report the a non existent exercise.
Other students are ok, or at least looks like.
I'm trying to find others with same issue.

See that on other course, the exercise has two different results, but only one attempt.

PROGRESS ISSUES:
On the same report on other course, the student has


See above that on the linepath (i)info, the same report is showed correctly for the user.

Expected behavior / Resultado esperado / Résultat attendu

Consistent and correct results on both student frontend and admin backend.

@AngelFQC Could you explain me the procedures to do so?
I tried to register but got an error as seen on the SS atached.

[AngelFQC]

Try again 😄
Or enter with _admin_/_admin_

[marshel]

Ok, got registered, with some errors...

How you suggest I try to reproduce?

[AngelFQC]

Create a course with users, exercises, learn paths, etc..

@marshel, if you can't reproduce it on 1.11.chamilo.org, we can't reproduce either, so I'll close the issue. I'm leaving you 3 days to update...

Sorry I could not reproduce. I did not had the time and there are for lot of variables to look at.

I will state some things I believe may be the cause so when someone reviews the code may look at it.
1st. - The linepaths are Generated on Articulate Then joined on Captivate for Scorm compliance.
2nd. - Then on Chamilo, is added to the linepath the 3 forums, 1 exercise.
3rd. - Most of the users can finish it without the glitch, with complete 100% status/progress. Some student on report are showing the progress errors.
4th. Lookint at the DB, the c_lp_item_view are correct, but the c_lp_view show error on the collumn progress.
5th. - There are multiple linepaths showing this behavior.

Things I ask myself:

• is the session time on php/apache a factor? (I.E. leaving the browser at a lp item for 90min for ex.)
• is the lp controller giving some users a error? (may posting or not posting on the forum, or yet on clicking or not on the home button)
• is the page that record the progress on the DB doing some wrong calculation or missing the record part?
• is the way that the Scorm is eddited the reason? but then, should not all the users have the same error?

I will keep looking and report when/if I found something useful.

Thanks @ywarnier and @AngelFQC .

No problem, there will always be time to reproduce it and fix it, if that happens.
