Vaadin Framework Grid (Java version) default sorting not working

Vaadin Framework Grid (Java version) default sorting not working at all, even with the crud example, or am I missing something, ?

In the CRUD example doesn’t work on purpose (sort of); more specifically, it’s not been implemented, because the example uses a fake backend that doesn’t implement sorting. If you create a plain Grid with an in-memory database, sorting should work out of the box. If you look at the chapter about lazy loading in the docs, you will find an example of sorting in a lazy container: https://vaadin.com/docs/-/part/framework/datamodel/datamodel-providers.html#datamodel.dataproviders.lazy
