Hi Karen,
I just want to give some feedback, when I commented out if (useridMap.containsKey(agented) the "failed to call histogramScores" error was fixed. Then unfortunately our export kept on timing out but I did find some jiras to solve that and applied it.
We are still experiencing some export timeout errors on sites with over a thousand students but I think it because of the way our AD is setup.
Just a question, it looks like if a student submitted an assessment 50 times then a call is made to the AD 50 times, if this is true then maybe we can change that to make a call per student to the AD and not per assessment. This might improve the speed of the export?
Can you advise or am I misunderstanding?
Thank you for all your help so far.
Regards

Hi Sonette,
If you comment out if (useridMap.containsKey(agented), I agree that the exception will not be seen because useridMap is not null. I think this can be a workaround to generate the export result. Just remember that your exported data will contain answers and scores for these inactive students.
Thanks,
Karen

HI Karen,
Please find attached txt file with content of the select that was run.
I did apply SAM_848 but that did not resolve our problem.
What I've done know is I commented out the code if (useridMap.containsKey(agented). So that scores.add(data) must be executed. Plus minus on line 249 of HistogramListener.java. I resolved the problem on dev.
Do you see any problems if we do not do that test?
Enjoy your weekend.

Hi Sonette,
When I re-read your attachment, I notice you still have active students for that assessment. But according to the piece of code you pointed out, it returns false only when there is no active student:
The rest of the code is then not executed because false is returned:
Iterator iter = scores.iterator();
//log.info<http://log.info/>("Has this many agents: " + scores.size());
if (!iter.hasNext())
return false;
So I am not sure if above code is the cause of you issue, and not sure if SAM-848 is the right fix. Please confirm.
Thanks,
Karen

Hi Sonette,
Thanks for the useful information. I think you have the same issue as http://jira.sakaiproject.org/browse/SAM-848. I cannot merge the fix to 2.6.x yet because it has not been verified and closed by QA. However, because the fix is straightforward, you can merge the fix to your local QA instance and do some testing there. If things look good, you can then apply to your production instance.
Thanks,
Karen

Hi Karen,
Thank you for your reply.
No our problem is not the same as SAM-1026.
I suspected that the error was happening in the mentioned rows below, but know after your email realize that I was on our development box and that there is no active students for that assessment.
There are active students on production so the error below is caused by something else.
Here is the error we are getting:
010-10-20 07:48:13,542 ERROR [com.sun.faces.lifecycle.InvokeApplicationPhase] - <java.lang.RuntimeException: failed to call histogramScores.>
javax.faces.el.EvaluationException: java.lang.RuntimeException: failed to call histogramScores.

I am still investigating what is causing this bug but please if you've got any ideas on how to resolve it send it to me.

Warwick and Sonette,
The lines you pointed out happens when there is no active student for that assessment, not just one student. Can you please check your assessment and let me know?
Also, what make you think the error happens from these lines? Do you think http://jira.sakaiproject.org/browse/SAM-1026 report the same issue? We haven't been able to find out a case to figure out the cause. Can you reproduce this error consistently? If yes, can you do the follow queries and send me the results:
SELECT * from sam_assessmentgrading_t ag, sam_publishedassessment_t pa WHERE ag.publishedassessmentid = pa.id<http://pa.id/> AND pa.title = :assessment_title
SELECT * FROM sam_itemgrading_t WHERE assessmentgradingid = :assessment_grading_id
Thanks,
Karen

________________________________
I was going through the program to try and see what is wrong.
I think our export might be breaking at this point:
HistogramListener.java method: histogramScores
If (!iter.hasNext)) {
Log.info("Students who have submitted may have been removed from this site");
Return false;
}
Will the export break if a user is not found?
Any suggestions?
Thanks

Hi,
We are also experiencing problems when we try to export. However not the same as Warwick.
Any ideas how to solve this problem please (patch for jira SAM_748 was applied). We are on Sakai 2.6.2.

I cannot export the test results of my Samigo test and I assume the cause is that, for some reason, the test shows 1 student in progress and 126 completed.
Any thoughts?
