Undo manager not working properly on undoing a remove action

Yeah undo triggers the change:columns, in your case you could try to wrap your updateColumns changes in editor.UndoManager.skip.

updateColumns() {
  editor.UndoManager.skip(() => {
    // your operations
  })
}

Ok I'm closing this one then and please open a new bug issue related to checkbox traits.

Thank you @artf it works, to fix this I was toggling the trait change listener by listening to undo command before & run events but this feels cleaner. The checkbox trait not getting checked or unchecked on undo/redo (trait value is updated on my end). Reproducible on Grapesjs webpage demo. Need help here as well thank you once again.

Thanks for reporting this, @FaisalShaikhHA.

Great question about Undo manager not working properly on undoing a remove action. The recommended approach with UndoManager is to use the event-driven API.

Start here:

1. Check the GrapesJS documentation for your specific module
2. Look for the on() event listener method
3. 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));

• Include what you've already tried
• Mention your GrapesJS version
