Describe the bug
How to reproduce the bug?
- Select components that available in canvas. Listen to a lifecycle event (e.g. component:selected)
- Call component.replaceWith() inside the event handler
- Perform undo
What is the expected behavior? Undo should safely restore editor state without errors, or GrapesJS should provide a supported way to replace components during lifecycle events.
What is the current behavior? Undo crashes because GrapesJS tries to restore selection/state for a component that no longer exists.
Question Is there a recommended, undo-safe way to replace a component during selection or status change events?

Thanks for reporting this, @jasonvijayy.
Great question about Crash when calling component.replaceWith() during lifecycle events with UndoManager enabled. The recommended approach with ProseMirror is to use the event-driven API.
Start here:
- Check the GrapesJS documentation for your specific module
- Look for the
on()event listener method - Most operations can be achieved by listening to editor and component events
Common patterns:
// Listen for changes
editor.on('change', () => console.log('something changed'));
// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
