3032597 - Freezing/Loading when Navigating Between Content Objects in Course Home (enableCourseHome)

Symptom

When using non-blended Course Home and multiple Content Objects are associated to an Item, if the user navigates between one content to another, there screen/content freezes. There are three loading dots but nothing happens after waiting.

Environment

SAP SuccessFactors Learning - 2H 2020

Reproducing the Issue

  1. Create an Item
  2. Create multiple Content Objects that are using SCORM or AICC
  3. Associate the Content Objects to the Item
  4. Enable Course Home
  5. Assign the Item to the user
  6. As the user navigate through the content and then choose the next content object
  7. Three loading dots appear but the second content object never loads

Cause

Certain content does not utilize the expected Exit call to finalize communication. When the user attempts to access the second Content Object which would then initialize API communication, as the previous API call has not ended, the issue occurs. Not all content is created the same and specific click streams through the content will yield different results on when the Exit call is done thus the issue might not occur all the time.

Resolution

The issue is resolved in the 1H 2021 release.

First workaround:

  1. Navigate to System Administration > Configuration > System Configuration
  2. Edit the LMS_ADMIN configuration file
  3. Find enableCourseHome and change to false
  4. Apply Changes
    • This change will impact all Online Items

Second workaround:

  1. Reach out to a Content Developer to make sure that the Exit command is called to end the previous content API communication.
    • SAP Support cannot provide assistance with content troubleshooting and a content developer should be engaged.
