Symptoms

When trying to remap the rule in question, you still get the same error once you exit the form.
 

Diagnoses

When you have a form after deploying from 4.6.11 to 4.7 you will see that the form in question has red ALM errors. When choose to go into the form rules you see there are expressions within some of the rule configurations in an error state (unresolved).
If you choose to remap this, it will appear fine until you exit the configuration completely and that is when the same error happens again.

What is the root cause of this ?


 

Resolution

This has been logged as bug and will be dealt within future releases of K2. The current workaround that is being used is to remap the expressions is to set the expression to none and then use the context browser to select the expression again rather from the eclipses.
