Security.ObjectLevel - Introduce an "Object Owner" feature into the XAF Security system

We already have a corresponding suggestion for this functionality: Security.ObjectLevel - Introduce an "Object Owner" feature into the XAF Security system and this example describes the idea on how to implement it yourself.

To accomplish this task, do the following:
1. Implement a Complex Security Strategy in your application;

2. Implement a helper class from the How to perform some actions only if the currently logged User belongs to a certain Role KB Article in the platform-agnostic module of your application;

3. Implement a Document class in the platform-agnostic module of your application as shown below.
Take special note how we initialize the properties of the business class in the AfterConstruction method. Refer to the Initialize a Property After Creating an Object help topic if necessary.

4. Implement a ViewController that filters the ListView by the CreatedBy property as shown below.
Refer to the Filter List Views help topic, to learn more about the used approach.

5. Run the application and log in first under John and then under Sam. Notice that in the first case, you can see only documents owned by John. This feature is enabled only for the Users role. Administrators (Sam) can view the documents created by all the users.
