I found that the older event args have a 'cancellable' property, but don't see a way to do this for the IUpdater. Is there any way to cancel an IUpdater while it's running?
As far as I know, it's not cancellable with a property that can be set in the way you're thinking.
However, you can cancel it by using the Failure API and posting a failure with a severity level of error at any time during the IUpdater. This will undo any changes made during the IUpdater as well as the action that triggered it.
