May be.
But I don't undestand why.
Is there something missing in the classes linked to my authentification error message.
One precision,
This message
"11:01:08,787 WARN [org.alfresco.web.ui.common.component.evaluator.BaseEvaluator] Error during ActionInstanceEvaluator evaluation of org.alfresco.web.action.evaluator.RegenerateRenditionsEvaluator@4ad258: 012813569 Access Denied. You do not have the appropriate permissions to perform this operation."
does no't prevent the user from doing his tasks (adding modifying or deleting items)
Second question
i can see that the jira issue have been assigned to me, what does this mean ? - No more alfresco pesons will be concerned by this issue ( which i agree may not be a bug).
thank you.
