Bonjour,
Je travaille sur Alfresco 3.4e.
J'ai modifié le modèle de données afin d'ajouter un statut (Brouillon, Validé, etc) à mes documents et j'ai développé le workflow suivant dont le but est de faire évoluer le statut du document associé au workflow.
Voici la définition du processus de mon workflow :
erson dans le type mbswf:validateByTeam_teamSelection) à qui l'on affecte ensuite des tâches de validation.
La tâche de validation présente un timer qui déclenche au bout de 5 minutes la transition ok.
Les classes SetStatusNameAction et SetStatusNameAndDateAction modifient les propriétés du noeud associé au workflow (statut et date de validité du statut).
Voici par exemple le contenu de SetStatusNameAndDateAction :
Au déclenchement du timer, j'obtiens l'erreur suivante dans les logs :
Les développements concernant ce workflow (modification du contentModel, définition d'un modèle pour le workflow, déploiement du workflow, classe appelée dans le workflow) sont les seules modifications apportées à Alfresco.
Je n'ai pas de problème sur mes transitions ok ou ko lorsqu'elles sont déclenchées par l'utilisateur.
Merci d'avance pour votre aide. N'hésitez pas si vous avez besoin d'infos complémentaires.
