Symptoms

Unable to P&D App into Production - Reference error (Remote Event Receiver / RER)
 

Diagnoses

There are 4 lists

- MainList (Main)

- SubList1

- subList2 

- sharedlist

shared List has a workflow that have event receivers in existence. The problem comes in that shared List is not the MAIN list. It's a shared list that is 'selected' during the deployment phase. So during the refactoring and resolving process, the MAIN list's event receivers are found on the target and subsequently resolved. However, when you select the SmartObject for shared List and the refactoring happens, the event receivers are refactored, but they are not re-compared and their conflicts are not resolved, leading to the 'missing reference' errors.
 

Resolution

Isolated patch was installed and the fix will be included in the next release of K2 (Appit 1.5 / blackpearl 4.7)
