Vaadin designer and mysql database

Can’t seem to find a guide on how to use the designer and bind components to a mysql database, any help is appreciated.

Designer is not an application generator, i.e. there is no functionalities to bind forms to data source directly. Currently Designer is visual design tool and building the data model and binding to data is outside of its scope.

Sounds like you could benefit from the recent book [Data-Centric Applications with Vaadin 8]
