How can I create a converter?

When I use buildAndBind , Vaadin send me this message:

Caused by ConversionException: Unable to convert value of type com.gldos.GCOOP.cliente.Cliente to presentation type class java.lang.String. No converter is set and the types are not compatible.
->>   98 | convertFromModel  in com.vaadin.data.util.converter.ConverterUtil

I think I need CustomConverter but I have no idea on how to implement this.
