Hello,
I am trying to use a FieldGroup to bing a JPA entity item from a JPAContainer.
I get the exception:
com.vaadin.data.util.converter.Converter$ConversionException: Unable to convert value of type org.eclipse.persistence.indirection.IndirectList to presentation type class java.lang.String. No converter is set and the types are not compatible.
I see in the JPAcontainer documentation and examples that there is a FieldFactory implementing FormFieldFactory which is deprecated. But I can’t find any FieldGroupFieldFactory implementations suited for the fields I need.
Can you help me?
Thanks,
Francesco
