Exception in writing ACE to a reference for new user

[sergio]

Hi all.

I have the following piece of code:

Store store = new Store (schema, address);
         UserDetails[] userDetails = administrationService.createUsers(new NewUserDetails[]{newUser});
         Reference ref = new Reference();
         ref.setStore(store);
         ref.setUuid(homeFolderId);
         Predicate pred = new Predicate();
         pred.setStore(store);
         pred.setNodes(new Reference[]{ref});

The code works well: a new user is created and the entry point reference is well defined.

I have to give the user only read rights to that reference, so I tried the following piece of code:

ACE[] user_ace = new ACE[]{new ACE(homeFolderId, Constants.READ, AccessStatus.acepted)};
accessControlService.addACEs(pred, user_ace);

The user is correctly created but the following exception is thrown:

The line of code that throws the exception is the following:
accessControlService.addACEs(pred, user_ace);

Why?
And what is exactly the meanin of these tgwo lines of code?
How can I invite a the new user to another reference (folder) with the role consumer?

Many thanks to all.

All the best,

Sergio

this is a procedure to assign READ permission to a user for a space.
Was written in C#.net 2005, but is easy to know how works with ACEs an ACLs..
I traslate it for english user
Sorry for my english  :lol:

        private void msAssignUserReadPermisionToSpace(string spaceID, NewUserDetails user)
        {
            Alfresco.AccessControlWebService.Reference Ref = new Alfresco.AccessControlWebService.Reference();
            Alfresco.AccessControlWebService.Store spacesS=new Alfresco.AccessControlWebService.Store();

            spacesS.scheme = Alfresco.AccessControlWebService.StoreEnum.workspace;
            spacesS.address = "SpacesStore";
            Ref.store =spacesS;
            Ref.uuid = spaceID;

            Alfresco.AccessControlWebService.Predicate pred = new Alfresco.AccessControlWebService.Predicate();
            pred.Items = new Object[] { Ref };
            //remove the ACEs assign in the creation of the user
            Alfresco.AccessControlWebService.ACE[] aceRemove ;
            aceRemove = new Alfresco.AccessControlWebService.ACE[1];
            aceRemove[0] = new Alfresco.AccessControlWebService.ACE();
            aceRemove[0].authority = user.userName;
            aceRemove[0].permission = Constants.ALL_PERMISSIONS;
            aceRemove[0].accessStatus = Alfresco.AccessControlWebService.AccessStatus.declined;

            Alfresco.AccessControlWebService.ACL[] aclr = controlservice.removeACEs(pred, aceRemove);
            //the remove process was ok
            if (aclr.Length > 0)
            {
                //add the read permission to the user for space
                Alfresco.AccessControlWebService.ACE[] aceRead;
                aceRead = new Alfresco.AccessControlWebService.ACE[1];
                aceRead[0] = new Alfresco.AccessControlWebService.ACE();
                aceRead[0].authority = user.userName;
                aceRead[0].permission = Constants.READ;
                aceRead[0].accessStatus = Alfresco.AccessControlWebService.AccessStatus.acepted;
controlservice.addACEs(pred, aceRead);
                //set owner of space
                //Alfresco.AccessControlWebService.OwnerResult[] or = controlservice.setOwners(pred, user.userName);

                if (acls.Length > 0)
                {
                     //OK
                }
                else
                {
                     //ERROR
                }

            }
           
        }

Hope this help
