Service Tree doesn't display service with ancestry



I’ve updated my euwe to get latest patch, and now I’m unable to view service that have an ancestry, I can only saw the “root” service which has ancestry=nil.
I think it’s related to this PR

Is it a bug, or I’m missing something?

edit: After doing a checkout and restart appliance, this problem is gone.

For 2 weeks, I faced this issue again. Only the root service is shown, all services that have an ancestry aren’t displayed. I’ve tried to change ancestry for some service to nil, and now they are visible.

How can I correct that?
