Problems uploading files in Safari 11.1

Problem: We are seeing reports of failed uploads and errors when uploading files using Safari 11.1.  Blackboard has identified this as a bug and we are waiting for a resolution.

Solution: Other browsers such as Chrome and Firefox appear to be functioning as expected.  Please use these browsers if you encounter issues uploading files in Safari.

Unable to download submitted assignment files

Problem: When grading an assignment, some assignment files present an error after clicking the download file button.

Solution: We are working to find out the cause of this issue.  In the meantime if you experience this problem, the workaround is to download all assignment files at once.  This can be done by going into the grade center, clicking on the button to the right of the column name, and selecting Assignment file Download.

Assignments do not display in-line within the browser in Safari on OSX

Problem: Assignments do not display in-line within the browser in Safari on OSX.

Solution: Use another browser, or modify Safari’s privacy settings to allow the assignments to display in the browser.  Depending on your operating system version (to check this, click on the Apple in the upper left corner of your screen, then About this Mac), the steps for this are:

  • If you are running Sierra, go into Safari > Preferences > Privacy > Cookies and Website Data > set to “Always Allow”
  • If you are running High Sierra, go to Safari > Preferences > Privacy > unselect Prevent cross-site tracking

Downloading/Viewing attempt in Grade Center produces an error

Problem: When going into the grade center and viewing or downloading an assignment attempt, users see an error message similar to “No default constructor found.”  We’ve seen this occurring when attempting to access group attempts as well as individual submissions.  Blackboard has identified this as a bug, and we are currently working to clarify patch availability.

Solution: Please contact blackboard@uvm.edu as soon as possible if you see this error.  In the meantime, the workaround for this issue is to click the chevron next to the Column Title and download all assignment attempts.

Assignments not submitted via the Assignment tool cannot be graded by rubric

Problem:  When an instructor is using the assignment tool and associated grade center column, but students submit an assignment outside of the assignment tool, the instructor cannot use the Rubric Tool to create a grade. For example, if students send their assignments via email or provide a paper version instead of using the online dropbox, there is no submission recorded in the grade center column for that assignment.  This means that the instructor cannot use the Rubric Tool to calculate and provide feedback on the grade.

Solution:  This is a known issue, however Blackboard has not indicated a fix as being planned in a future release.  Workarounds aren’t ideal, and include asking students to submit an empty document digitally in addition to the alternative (paper, email, etc) submission.

Cannot upload assignment feedback via Grade Center’s “Work Offline” mode

Problem: Downloading an assignment in the grade center, then entering feedback into the feedback column in Excel, then uploading the file to the Grade Center, does not result in the feedback being saved.

Solution: This is a known bug, and a fix is expected (though not garaunteed) sometime in mid-December. In the meantime, feedback can be entered via the web interface on a supported browser.

Can’t open assignment files in Bb Grader app

Problem: When viewing an assignment in the Bb Grader mobile application, assignments are not displayed, and attempting to open them in a different application results in no action.

Solution: UVM does not yet support inline grading of assignments. This means that assignments will need to be downloaded and graded within the web interface on a laptop or desktop computer, in a supported browser.
