AF SDK Events on AFElement level

Hi,

 

 

 

I have the folowing situation:

 

 - There is an Element E in PI System with Atrributes A1 and A2
 - The attributes A1, A2  have as DataReference different PI Points
 - The type of atributte value is Double
 - The application App1 writes to PI and updates(changes, inserts) values of Element E(some or all attrubutes have new values)
 - The Application App2 receives notification when element E has changed

 

I tried to implement this use case in C# using Event Example described in the AF SDK reference. The example is written such that Events occur on the AFDatabase level

 

and I can not translate it onto level of AFElement. Also, when I try to call  FindChangedItems I always get that the number of cahnged Items is 0.

 

Can someone help me with my problem? Any hint is welcome.
