Strange behaviour of property db.IsClusterReplication

I hope someone will respond to this:

I have a cluster with two servers. Cluster replication is enabled for all mailfiles.

But if I put this script in a button in a mail in any given mailfile:

Dim session As New NotesSession

Dim db As NotesDatabase

Set db = session.CurrentDatabase

If db.IsOpen Then

Messagebox db.IsClusterReplication

End If

The result is always “False” … Why ??? What results do you get ?

Cluster Directory ( cldbdir.nsf ) correct shows that Cluster Replication is enabled for all mailfiles.
