Issue/Introduction

We're running AdminUI, and when we try to access to any Task panel,
then the AdminUI reports error in the browser :

Error: The statement was aborted because it would have caused a
duplicate key value in a unique or primary key constraint or unique
index identified by 'FK_TASKSESSION12_5_TASKSESSION12_5' defined on
'TASKSESSION12_5'.

Server.log :

Caused by: java.sql.SQLException: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'FK_TASKSESSION12_5_TASKSESSION12_5' defined on 'TASKSESSION12_5'.
