Hi, Dev Team
How to get modified records as JSON objects from Gantt and Scheduler?
Support Forum
You can read https://www.bryntum.com/docs/scheduler/#Core/data/Store#property-changes from any of the involved stores (resourceStore, eventStore and so forth)
That looks like a bug, we'll look into it. https://github.com/bryntum/support/issues/2330
Why you cannot use https://www.bryntum.com/docs/scheduler/#Core/data/Store#property-changes ?
