I think that the view is getting updated after the save, but before your postsave code runs. Perhaps the notesview.refresh method will help? Put it at the end of your Postsave code.

If that doesn't work, you could also experiment with notesuiworkspace.viewrefresh.

If you are changing  the source document in the Postsave then you will need to be very careful that you do not create Save/Rep conflicts. 

Having said that as was previously suggested calling the view.refresh method might solve the problem. However, depending on the nature and volume of changes this could cause a fairly serious performance hit. 

I would look into putting it into the querysave, but that might not be possible.

... is uiview refresh at the end of Postsave:

.....

Call doc.Save(True,False)    

Dim uiws As New NotesUIWorkspace
Call uiws.ViewRefresh

End sub
