Warnings reference › scheduler:read-only-refused

Identifier

scheduler:read-only-refused

Raised by

scheduler

Since

1.97.0

What happened

A pointer or keyboard edit targeted an event (or a resource) marked read-only - readOnly: true on the row, or the scheduler's readOnlyWhen/resourceReadOnlyWhen predicate - so the gesture was refused before its before-event fired. No data was written and no event:change was raised.

The fix

Edit a different event or resource, or remove the readOnly flag / loosen the read-only predicate.

The smallest fix

events: [{ id: 'e1', resourceId: 'alice', startDate: '2026-03-02 09:00', readOnly: true }]
