Today, while developing my managed bean that should send mail alerts, I have discovered a strange thing. There seems to be two JAVA classes

lotus.domino.local.Document

 
lotus.domino.Document

 

They seems to be (to my surprise, thanks to my limited knowledge of JAVA I guess) interchangeable to certain extend. The code snippet below output is    class name: lotus.domino.local.Document

 

lotus.domino.Document project = DominoUtils.getCurrentDatabase().getDocumentByID(documentNoteID);

System.out.println("class name: " + project.getClass().getName());

 

So far I did not notice that as everything works fine. But when I tried to add document link to RTItem and passed the project variable it fails with the following error

06/04/2011 03:11:17 PM  HTTP JVM: NotesException: AppendDocLink requires a NotesDocument, NotesView or NotesDatabase argument

 

BTW I tried also use cast to get the propert class but it did not make any change.

 

Any help would be highly appreciated.
