Our App used to use the AuditTrail module back when we were using mendix version 5.18 or 5.20. I can't remember exactly when but we deactivated the module for performance reasons. I think we did so by removing all related event handlers on the entities we were tracking.
Now we're on version 6.3.1 and are ready to reactivate the module. I'm assuming we used the events and association method to implement the module before since the AuditTrail.Log entity already has the appropriate relationships to the entities we want to track. I followed the instructions in the readme and added a Before Commit and Before Delete event handler to the BillingSheet entity (the entity I want to track). I noticed the readme mentions an After Create event handler but the AuditTrailSuperClass entity doesn't have an event handler for that. Maybe that's the issue?
When I try to change a BillingSheet object, I get the following error and stacktrace:
An error has occurred while handling the request. [User 'adrewen' with session id 'f94b21bc-fe77-481e-a56d-939cf1d97eee' and roles 'PAAHAdministrator, PAAHUser']

It looks like the error is caused by the change action which creates a relationship between the BillingSheet and the Log objects after the java action. It also looks like the Log object is not being created. We are using version 4.0 of the AuditTrail module. Please advise on how I can fix this.
