PR Summary

The problem is that using PS Adapter implicitly means the engine dynamically creates a new configuration that wraps the resource with appropriate adapter (PS7 or WinPS5.1). This gets run which works fine. However, a part ofset also performs aget to get thebefore_state. Aget returns the payload asresult, however, the actualbefore_state as defined in the configuration isresources. So the fix is to address this situation wherebefore_state needs to be retrieved at runtime and make it look like a correctset response.
