Games Module - Completion Error

by David Morrow - Thursday, October 25, 2012, 11:47 PM

Greetings - and apologies if I am posting this to the wrong place.

The Crossword and Hangman games are giving the following error and stack trace. Any help would be greatly appreciated - our teacher really like these. The error comes after checking the the puzzle. These errors are coming after installing the latest version of the Game module in response to a different error. We are running Moodle 2.3.2 (Build: 20120910).

Many thanks in advance,

Does turning off activity completion clear the error? I am not offering that as a fix, but it looks like that is generating the error.

Thanks for the rapid response. The short answer is "sort of".

Here are results with the following settings

"Do not indicate activity completion" = no error
"Students can manually mark..." = no error
"Show activity as complete when conditions are met" and the condition "Student must view..." = no error
"Show activity as complete when conditions are met" and the condition "Student must receive a grade..." = ERROR
"Show activity as complete when conditions are met" and BOTH conditions selected = no error (this one really surprised me)

And this little something extra with that last situation - if I try to change the settings (logged in as admin) from both conditions to just "Student must receive a grade...", the following error and stack trace result:

An internal error occurred in the completion system. (System administrators can enable debugging information to see more detail.)

The changes seem to stay, but returning to the activity settings and saving again returns the same error. And a student account receives the previous error when exiting the activity.

I would be happy to provide any more information, and thanks again for any help or insight.

I think the best way to get this fixed would be to create an issue in the tracker. The game module developer will get the issue assigned to him by default. In the past, he has been reasonably quick in fixing issue with the module. If you create a tracker item, please post the number back here so others can vote/watch it.

Sorry, according to his profile (https://moodle.org/user/view.php?id=22735&course=5) Vasilis last logged into this site Oct 11th, 2012. You may want to message him.

He is also accepting donations (I have donated). The games module is massive and fantastic.

Hi David,

I heavily used this module in my Moodle 2.2.x -- it has some minor quirks and bugs but generally worked well.

I've started a brand new Moodle 2.3 and have not installed the game module yet.

https://moodle.org/mod/forum/discuss.php?d=206091

A few people posted that they found no problems under 2.3, but none of them said they use Course Completion features.

My question: If you disable course completion, does it work fine?

I have use it with 2.3 since upgrading in August. The module was updated after CONTRIB-3795 was reported in the tracker.

Sorry I've gotten behind in my replies.

Everything seems fine as long as the completion tracking is not using "Student must receive grade" as the completion condition.

The teachers who were having the problem seem happy now that they know to leave off that one option, so I haven't taken the time to start a tracker item.

Thanks, all!

David
