I would think it is a FK to a node. Does it contain values?
First thank you for response.
I see it again. I would think it is a index of same node's LeavingTransitions.
But how is it persisted?
It is part of the processdefinition, so I'd guess it is set somewhere in the process parser. Actual storage should be done by hibernate, but if there is no config for it, I don't know (I'm no hibernate expert)
