Remarks
This method is for internal use. It can access certain Object Spaces XAF uses internally (for example, the Object Space used by the Security System). Do not use such Object Spaces in your applications because this may cause unexpected behavior. Instead of this, implement the approaches below.
Within the object’s class code, use Session and its methods instead of an Object Space.
In other scenarios, create a new Object Space and use the GetObject(Object) method to retrieve an object in the current Object Space. Refer to the method’s description to see an example.
