Problem to open up Child case type Vehicle Rental from Case type Reservation

[OGGG33 (Oscar Grimsvik)]

Hi,

I am doing the last Exercise: SAE 8 Solution Build in the course System architect essentials 8.1 https://academy.pega.com/academyapp/library

I have come a long way with this excerise, but now I am stuck on the step where you from Case Type Reservation should be able to open up the Child Case type Vehicle Rental directly. But for some reason I don’t mange open the Child case type Vehicle Rental directly(automatically) after I have click on the Submit button in Reserve Vehicle step. I coming to an empty screen and are still in the Reservation case type, but if i press the refresh button i am able to open the vehicle rental case manually.

But I don’t want to open it manually i want to be able to open it directly after I have click on the submit button. In other words I want my solution to be like picture Reserve Vehicle and vehicle rental child case.

If you have any idea what I have missed or done wrong please answer my question.

Thanks in advance
