ResourceVF not always provisioned

In Closed Loop -> Properties CL: When opening the popup window, the first service in the list does not show Resource-VF even though in SDC there is a resource instance in the service. 

Workaround:

If you have multiple service available (if not create a dummy one on SDC), just click on another one and then click back on the first one in the list. The ResourceVF should be provisioned now.
