one of the components unmounts, the subscription is evicted from subscription cache
the component that is still mounted would have a nil subscription
The error was calling dispose! on unmount. The solution is to use reference counting, storing the counter on the subscription itself (this will be either a reagent.ratom.Reaction or reagent.ratom.Cursor). When the reference counter is zero it is safe to dispose of.
There was a bug:
