Hello Tadej. If you inspect the ListApplications method inside the HRSpecialist observer class, you will see that it already checks that. So what you can do is create a method in that class to do the check for you and then just call it before listing all the applications. But again, the ListApplications method already does that for you.

Thank you fir this article!
I have additional question about it.
From your example I see you’re calling observer1.ListApplications() when you know the provider.AddApplication(new(1, “Jesus”)) has been called once before.
My question is, is there any chance to know if the application has been added and only than call ListApplications()?
Thank you for this article and thanks for any suggestion on my question.
