OK, habe mal folgendes Script gebastelt:
Dim Session As New NotesSession
Dim db As NotesDatabase
Dim coll As NotesDocumentCollection
Dim loopdoc As NotesDocument
Dim item As NotesItem
Set db = session.CurrentDatabase
Set coll = db.UnprocessedDocuments
Set loopdoc = coll.GetFirstDocument
While Not(loopdoc Is Nothing)
Set item = New NotesItem( loopdoc, "werdarf", "[STH]:[BOZ]:[ASH]:[Admin]", READERS )
item.IsReaders= True
Call loopdoc.Save(True,True,True)
Set loopdoc = coll.GetNextDocument(loopdoc)
Wend
ist ja alles okay, bis, das das Feld "werdarf" keine Textliste ist.
