Description
Steps to reproduce:
- create a class with a Date property for which you programmatically set the value for "EmptyIsToday" to null.
- edit the class and check "EmptyIsToday".
In the server logs you will see
ERROR .o.i.DefaultObservationManager - Failed to send event [org.xwiki.bridge.event.DocumentUpdatedEvent@d43b8e0c] to listener [com.xpn.xwiki.internal.event.XClassPropertyEventGeneratorListener@691639c6]
If you have watchlist notifications and trigger for instance the hourly notifier, you will see
