Notes Some Frustrations

I've posted a question on notes.net but thought I would duplicate it here in case anyone can help:-

" We have a domino 8 server running with a DB2 test server setup as a backend (on same machine). The DB2 backend is working fine and we have created a view in our DB2 enabled nsf. We can populate this view and see the data in DB2. We are having problems where a doc gets updated in notes but the change doesn't get populated to DB2 until we 'populate db2' from designer. The help indivates that a DAV should instantly update DB2 when data changes within the view. This is not happening.

Any help appreciated!"

As I say in the question above I was expecting the DAV in DB2 to automatically update (as the help docs say it will but doesn't seem to do it. Anyone got any experience of this?
