    The following code give me a "server side not implemented" error at runtime.
    public IList<short> VisibleBooks(short userID)
    {
      return this.Context.my_roles.Where(r => r.UsersIDs().Contains(userID)).SelectMany<my_role, short>(r => r.VisibleBookIDs()).Distinct<short>().ToList<short>();
    }


    I'm using OA 2011.3.112 against SQLserver 2008.

    I saw an old thread on similar subject where it's stated that it has been fixed but it looks like it doesn't apply to this.

    Found the cause for the error.
    The UsersIDs is a method or extension on the OA role that returns list of user Ids.

    The work around I found was to put the "select" into the LINQ and materialize it before the SelectMany.
    So it looks something like

    public IList<short> VisibleBooks(short userID)
    {
     var tmp = this.Context.my_roles.Where(r => r.users.Select(u => u.UserId).Contains(userID)).ToList();
     return tmp.SelectMany<my_role, short>(r => r.VisibleBookIDs()).Distinct<short>().ToList<short>();
    }

    Hello Björn,

    OpenAccess cannot look into methods on the persistent types that are beeing called. This is why using the Users collection worked, whereas using UsersIDs() did not. The same applies to VisibleBookIDs().
