Issues with Repository Hooks OnAddExecuted OnDeleteExecuted

[Dannie F]

I am trying to implement an audit attribute where I serialize the entity to the table. However i am having the following issues:

1. In the OnAddExecuted hook, the identity key is not refreshed from the database. The primary key is an integer whose value is 0 before the Add operation, however in the hook, the value is not set from the database.
   
2. In the OnDeleteExecuted hook, I am deleting an entity with a navigation property set, however the value of the property is null in the hook.

Any insight would be appreciated.
