Problème page wiki depuis migration 4.0 vers 4.2

[aleroy]

Bonjour,

J'ai effectué une migration d'alfresco community 4.0.d (sous linux avec une base postgresql) vers la version 4.2.a.
Mais depuis, les pages wiki de certains sites share ne s'affiche plus.
J'ai l'erreur suivante quand je récupère la page via http://localhost:8080/alfresco/s/slingshot/wiki/page/alfresco/Main_Page?context=/share/page/site/alf... :

Ce que je ne comprend pas, c'est que cette erreur ne touche que certains sites.
J'ai analysé les logs mais vu aucune autre erreur à part celle-ci :

Savez-vous d'où pourrait venir le problème ?

Merci d'avance.

[rguinot]

N'auriez vous pas oublié de migrer certains modèles custom ?

C'est possible que l'erreur n'est rien à voir avec avec le flux JSON, mais plutôt lorsque vous tentez l'affichage de properties qui n'existent pas / plus.

J'ai résolu mon problème. Certaines pages du wiki n'avaient pas de titre de renseigné mais seulement le nom.
