Deletion of the Linked WI is not recognised on IWorkItemSave

Hello All,

Usecase: If Tracklinks is not present then do not allow the save operation.

i have followed the below article for creation of Advisor,
https://jazz.net/library/article/495

usecase works fine. But when i try to remove the tracks link manually and save , Advisor is not called at all.

If i change any field and remove the track links and save then Advisor is called.

Could you please help on this?

below is my code :
package operationadvisor;
