"Privilege 'Read' is not granted to " when workflow task is terminated

[Corinne_]

Hello all, I use nuxeo 6HF2 server. In a workflow, I grant specific permission to the task assignees. When the task is ended (validate ou reject button), the assignee gets a security error page. Because the current is the document view that is no more accessible by the user. I tried to redirect the user to home page, no success. How can I do? how to avoid that error ?

Solution : I had to grant Read permission to all participants. But It was not so easy to use setACL operation with group as the user parameter. I tried to use "group:groupname", "group:" prefix was wrong. There is a miss in documentation !
