Re: sample code of ERCAuditTrail

Hi, 

The ERCoreBusinessLogic stuff works great when simple values are updated.
But, what I can't figure out, is how to record changes in relationships between other objects.

e.g.  Media -->> Category

Can it do that?
Am I missing something obvious?

Cheers, 

Mark
