Good morning all

 

Thanks very much for the heads up on this.

 

I had tested the assignment tool but it had not occurred to me to test simultaneous submission.

 

I have just tested using four student accounts and three out of the four were affected, seeing the “could not write to private store” error.

 

Even worse, if you try to resubmit as one of the affected students you see the NPE message. As stated below Instructor cannot view either.

 

However, Instructor can clear the attempt and student can then resubmit successfully.

 

We are in the same position as you Julie, running SP12. I have our upgrade booked with Managed Hosting for first week in August but if there is no patch available before then, we will have to postpone. The assignment tool is one of the heaviest used features in Blackboard here and to knowingly impair its functionality in this way would be negligent, in my view. I would certainly lose all credibility with teaching colleagues. On the other hand, we must have full support for the system.

 

I will be logging a call this morning and talking to our account manager!

 

Regards

Hi Sandra,

 

We have also been able to replicate this and are also very concerned about whether we upgrade to the April14 release. This is just another in a list of issues with the April 14 release!

We are running SP12, which is due to be reclassified to no longer supported next month, so the pressure is really on for us.

 

We will be reporting this issue to Bb to add our names to the case and to push for this to be patched asap. I would suggest others do the same. We cannot have something as basic as assignment submission not working.

 

Best wishes

Julie

Subject: April14 Release Assignment Bug - error when students submit at same time

 

Hi,

We need to decide whether we proceed with out upgrade to the April14 release after we came across a issue affecting assignment uploads.

We were testing this with only 3 users and one was immediately affected, the idea that we release this into the wild with hundreds of students submitting to an assignment on one of our larger courses sounds like a potentially serious issue.

We only have one yearly upgrade window and October2014 will not be available for the start of the academic year, so we'd have to live with this issue for a year.

Is anyone else affected by this, and if so, do you have a cunning plan on how to deal this issue without alarming students by informing them that they are likely to get error messages during peak upload periods, or if anyone other than them is using the tool at the same time?

Steps to Replicate: 1. Create a course in Blackboard Learn
