我该如何创建转换器？

Question

当我使用buildAndBind时，Vaadin会将此消息发送给我：

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

我想我需要CustomConverter，但我不知道如何实现它。
