The EntryAlreadyExistsException comes in the Register Page.

Problem:
The existing User is getting Register Page after login into the iRAM Application. She is getting the Exception after click "Register" button javax.servlet.ServletException: #{pc_Register.doRegister}: com.ibm.ram.repository.core.IRepositoryAccess$EntryAlreadyExistsException: Duplicate entry. Could not create entry.

Root cause:
This user recently became IBMer, so her Employee(serial) number has changed from LV5RWU to 060257, but her email address (mvmtori@ar.ibm.com) is NOT changed. In iRAM database is showing LV5RWU613 value in USERID column and mvmtori@ar.ibm.com value in EMAIL column of USERID database table.

Note: This User has already submitted 37 assets in iRAM production.

Expectation/Request:
User expects to login without Register page and user will view and edit the own assets (37) in iRAM application.

Kindly provide valuable suggestion and solution to this problem.
