Is it possible dispatch an action after execute undo/redo command?

[wss29]

hi
I have a property panel for my node. When I select a node, the property panel displays the node's properties. I can edit values in the panel, and they update the node—for example, the name property.

However, when I execute undo or redo (using Ctrl+Z/Ctrl+Y), the values in the panel do not change immediately. Instead, I need to select another node and then reselect the current node to trigger the panel update. This feels tedious.

I want to dispatch an action to update the panel automatically after executing undo/redo. Is there any place where I can add code to implement this?

Hi @wss29 ,

You could simply listen for model root changes on the EditorContextService and trigger an update whenever the root changes:

    @inject(EditorContextService)
    protected editorContextService: EditorContextService;
    
    // listen for changes
    this.editorContextService.onModelRootChanged(newRoot => {
       // You update logic
    });
