In Writer, the meaning of 'parts' is a bit different than in Calc or Impress. In Writer, the parts mean pages, and the document does not give a completely different view, the cursor just jumps to the given page.
It is up to the client to follow the cursor appropriately to have the desired effect.
512b782 LOK: Implement parts for Writer too.
