After upgrade to the new Policy Manager: Layer7 API Gateway Policy Manager 10.1.00.13889-CR02 I found out, that a direct debugging of included encapsulated assertions is not possible any more.
My tests show that it is no problem of the new Gateway Version: Layer7_API_Gateway_v10.1.00.13889-CR02.
The debugging with the "old" CR01 Policy-Manager still shows that encapsulated assertion could be debugged directly.

Release : 10.1
Component : API GATEWAY
There is a new option in the policy manager preferences windows to enable this feature.
In Policy Manager 10.1.00.13889-CR02 to enable debug of Encapsulated Assertions, In the Preferences window, there is an option "Enable Encapsulated Assertion Debugging" which needs to be enabled.
