On organization chart service, when the sax of the view "organizationChart" failed, the message is for example
The entity Mairie (content://738268e3-9305-4273-85f0-40279b2005e3) is referencing an unexisting user 'content://6d97df27-be02-4a83-9ce5-01b0abe6bd56'
But the user exists. This is the sax of the view which failed.
Moreover the stack trace is missing.
