Pb Ticket

What object is responsible for displaying the items in workElement ticket?

Because yesterday, I realized that the party ticket in the elements belonging to WorkElement disappeared (real work, left work, Estimated work).
I do not understand what could have done this.

J'ai constaté que pour un utilisateur admin, le problème n'existe pas.
J'ai déjà vérifié que dans le model Ticket le champ WorkElement est toujours présent, maintenant je ne sais pas dans partie de code est traité l'affichage ses éléments, ni quels sont les conditions nécessaire à leur affichage.
J'avais effectué une modification dans le temps c'était lors de la function save de ticket je transmet idActivity du ticket à celui du workElement.

Do you have an idea?

I do not think, because I had information in the meantime, I have one server with ZendServer turned out that I had created a clone of this server. Meanwhile, the slightly changed (maybe the Apache configurations) without synchronized new servers. And today, for the same code and the same database, there is a server that returns the elements of workElement and the other does not do it.

So according to you, what are the changes to the server configuration may change the behavior tool?

you were right it was that

Thank
