I am designing a hierarchy of pages and components and I am trying to figure out what _attachBubbleHandlers is used for considering it basically does:
that._data.bind(ERROR, e => { that.trigger(ERROR, e);});where that._data is an ObservableArray which never triggers the error event.
See https://github.com/telerik/kendo-ui-core/blob/master/src/kendo.data.js#L4856
Please clarify.

Hello Jack,
You are right,.a plain ObservableArray cannot throw an error. But the HierarchyDataSource class is dedicated not only for ObservableArray class, but for DataSource instances as well. Those can throw an error and this specific code ensures that there is a bubbling of the parent event error to the child.
