[John Arthorne <john@xxxxxxxxxxxxxx>]

Is this your own view or the Navigator that is not refreshing? 
Generally, a viewer never needs to be manually refreshed from outside. 
The viewer will listen for changes to the underlying model (the 
workspace in this case), and update itself accordingly. So, simply 
changing the underlying model will cause the viewer to update itself. 
If you are modifying a file in the workspace diretly using java.nio, you 
will need to refresh the IResource, as you are doing in snippet #2.
