I have developed a Lightning app that uses the force event : e.force:navigateToObjectHome to get the user to an object page. This event has been working fine in 3 sandbox so far but now that I am testing it in a 4th sandbox the event has stopped working.
When debugging this issue I found out that the event is undefined in Sandbox #2. What would trigger such an issue? I even added the event as an aura:dependency to my component, and it still does not work.
The app itself is contained in a VF page and I have used Joe Buschmann example on how to send force events to the VF page and have the page handle them: http://joebuschmann.com/salesforce-lightning-navigation-events-in-a-visualforce-page/
