Due to an issue during index rebuild, I am dealing with some events without any workflows right now. While debugging the problem, I came across some strange behavior in the admin ui:
First, the event's workflows tab shows an empty list:
This is expected, as the corresponding request to Opencast failed:

But, after displaying another event's details and returning to the original event, that other event's workflows are suddenly shown:
I guess having events without any workflows attached should be quite uncommon, but displaying another events' workflows probably should not happen in any case and may indicate a bug somewhere in the admin ui?
