Environment

SAP SuccessFactors Learning

Reproducing the Issue

Login to LMS natively as an admin

Navigate to the "Home" tab

Java error message appears

Cause

This issue happens due to code is not updated in the extension module.

Resolution

This issue happens due to code is not updated in the extension module.

In the PlateauxAuthenticationContext.xml, there will be bean definition for com.plateausystems.plateaux.authentication.struts.PlateauxLearnerSuccessAuthenticationAction. The scope attribute of this bean is scope="singleton". We will have to update this attribute to scope="prototype".

However since this is an extension module update, customers will need to reach out to Professional Services for them to update these.
