If you extend the accelerator classes for alerts, barriers, or fulfillments in your implementation layer, you need to ensure that the work objects are created for the extended classes. To do this, save the DisplayAlertHeader, DisplayBarriersHeader, and DisplayFulfillmentsHeader section rules to the implementation layer and then use dynamic class references to create the work objects.

1. In Dev Studio, access your implementation layer by clicking application menu Switch application, and then click the name of your implementation layer.
2. Ensure that you have an unlocked ruleset.
