Hello,
Someone could explain if there is reasons to choose Binder against DataProvider and vice-versa ?
Thanks

In Vaadin8 Binder is used to bind data (e.g. entities) to forms including validation and conversions.

DataProvider is used when you have sets of data for the components like ComboBox list of items or Grid. So they have different purpose. DataProvider has facilities to sort and filter data and to customize those facilities (e.g. custom sorting).
