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.
Below the error report:

Not much information available I'm afraid...
In browser, error is:
An internal server error occurred. Please try again later.

Warwick,
What do you see after exported? An empty file or some errors? Do the scores pages (Total Scores, Question Score, View Student Score, etc) look ok?
Thanks,
Karen

Howdy
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?
