When i debug and select binder.forField(Field).getField().getValue or use binder.validate().isOk() everything works !

When i try binder.getBean it cames null

I’ve already read many options e examples but no one worked until now

Where do you call readBean or setBean?

You have to! Read the documentation

set bean for new record
read bean usually to populate existing fields to update righ ?

No. Please read the documentation: Loading & Saving to Business Objects | Data Binding | Vaadin Docs
