Completion error in Taskchain

Completion error in Taskchain

by Tom Tabaczynski -

Hello,

I started using Taskchain for my Hotpots, but I'm finding that when I set completion tracking for "Student must receive a grade ..." 

(1) I get an error message "An internal error occurred in the completion system (System administrators can enable debugging information for more detail)". I tried enabling debugging information but nothing's showing.

(2) completion is not marked. Because the activity completion is not marked, the next activity which is conditional on completion is not accessible.

(3) When I set access restriction (see attachment) it does not show. UPDATE: After I got rid of the access restriction in the following activity (19.5) the access restriction information for the Taskchain (19.4) started showing.

(Moodle 2.6)

Hi Tom,

what happens, if you replace the TaskChain with a HotPot and use the same completion conditions?

Hi Gordon,

I've been using Hotpots with these completion conditions up until now without any problems. The student gets a grade, the activity is marked as completed and the student can view the next activity. I was trying to replicate this with the Taskchain but it doesn't seem to work. I got rid of the completion tracking on the Taskchain and the error has gone. But I need the completion tracking to make sure sts do all the activities.

Hi Tom,

thanks for confirming that completion tracking in the HotPot module is working. 

I have had a look at the TaskChain completion code and I noticed that I refers to a non-existant DB table, so that is probably the cause of the error. Please give me a day or two to find a fix.

thanks
Gordon

Tom, please could you update your TaskChain module and let me know if the completion works on the TaskChain activity now. thanks, Gordon

I did and still the error message comes up when I turn progress tracking on. 

There seems to be some more general problem in the progress tracking system. I just tried, in another course, to make access to the next section/unit conditional on completion of a Hotpot in the previous section, with the next section visible but greyed out. 

Instead the next section is not visible at all. 

So this might not be a module issue, but a tracking system issue in 2.6??

It seems the TaskChain module does not yet do all that is it expected to do:

Debug info: Module taskchain claims to support
FEATURE_COMPLETION_HAS_RULES but does not have required
taskchain_get_completion_state function

Hi Tom,

I added the missing function to TaskChain and it seems to work OK now, that is to say the "complettion" is successfully detected and can be used to trigger access to other activities in the course.

Please update your TaskChain module and let me know if it fixes the issue for you.

I suspect that the HotPot module needs to be modified in the same way, so probably that is not working at the moment. I'll let you know when it is fixed.

best regards
Gordon

Tom,

I have updated the HotPot module confirmed that it is also working with Activity completion now.

Please update your HotPot module when you have a chance.

Thanks for bringing this issue to my attention approve

best regards
Gordon

Hi Gordon,

Thanks for that. The error message in the Taskchain has gone. But now, when I go into the Checklist page which I use for monitoring progress in conjunction with completion tracking, I get the following. I don't know PHP as yet to be able to understand what it means:

Coding problem: $PAGE->context was not set. You may have forgotten to call require_login() or $PAGE->set_context(). The page may not display correctly as a result

  • line 2842 of /lib/moodlelib.php: call to get_fast_modinfo()
  • line 46 of /mod/checklist/report.php: call to require_login()

As for the other issue, I updated the Hotpot module, but I still can't get the next section to show greyed out.

Tom,

the error message comes from the "Checklist" module. I suggest you talk to the Checklist developer about that.

In your post, you said:

> I still can't get the next section to show greyed out

I'm afraid it is not clear to me how what the "next section" is in the screenshot you gave. Also, none of the icons in the screenshot look like HotPot or TaskChain icons, so I need more help in understanding what the problem is.

regards
Gordon

Gordon,

Thanks, I'll take that to the Checklist module. Actually sometimes I don't know which module is responsible, so maybe you direct me where I might look in relation to the Access Restriction problem.
