Hi, I'm new to Umbraco, but I've found it simple enough so far. However, I'm having problems with the Saving event from ContentService.

I'm using the Saving event to validate and parse a file, and based on the results modify some of the properties of the content. After the event completes, it's saved... or so appears, because trying to navigate away shows the “Discard changes?” dialog. Discarding them, and navigating to the content again, shows that the changes actually were saved.

Is there any method I need to call inside the Saving event so that Umbraco detect that the changes actually were saved?
