Bom dia a todos.

Este erro se da quado crio uma lista dentro da Entidade Venda

Venda:

package br.com.fjsistemas.backend;

import java.time.LocalDate;
import java.util.ArrayList;
import java.util.List;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@AllArgsConstructor
@NoArgsConstructor
@Data
@Entity
public class Venda {

	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private Long id;

	private LocalDate dataVenda = LocalDate.now();

	@ManyToOne
	private Cliente cliente;
	
	@ManyToOne
	private FormaDePagamento formaDePagamento;
	
	private String valorTotalVenda;
	
	private List<String> descricao = new ArrayList<>();

}

e na minha View chamada VendaView tento setar o valor de uma variavel dentro desta lista

txtDescricao.setValue(txtProdutos.getValue().getNome().toString());
				txtDescricao.setValue(venda.getDescricao().toString());

RoinujNosde · Abril 29, 2021, 12:47pm

Por que descrição é uma lista?
Não deveria ser uma simples String?

rafaspara2017 · Abril 29, 2021, 12:49pm

@RoinujNosde

Eu tentei usar uma String simples, ai acontece o seguinte

Se uma venda tiver 1 produto, fica tudo certo, ele salva o valor no objeto e vida que segue.

Mas se a venda tiver 2 ou mais produtos, ele salva apenas 1 produto no objeto e os demais, são “descartados”.

Por isso tentei criar uma lista

RoinujNosde · Abril 29, 2021, 12:56pm

E a lista de produtos vendidos? Descartou?

rafaspara2017 · Abril 29, 2021, 12:59pm

@RoinujNosde momentaneamente sim

RoinujNosde · Abril 29, 2021, 1:16pm

Bom, esse erro é que está faltando a anotação de relação (ManyToMany, OneToMany, etc).

rafaspara2017 · Abril 29, 2021, 1:25pm

@RoinujNosde

já tentei as duas anotações, da o mesmo erro

Na sua view, qual objeto tem a propriedade “descricao”?

rafaspara2017 · Abril 29, 2021, 2:11pm

@RoinujNosde

na view

declarei esta variavel

	@PropertyId("descricao")
	private TextField txtDescricao = new TextField("Produtos:");

dentro do metodo adicionaProduto()

	txtDescricao.setValue(txtProdutos.getValue().getNome().toString());
				txtDescricao.setValue(venda.getDescricao().toString());

Property type 'java.util.List' doesn't match the field type 'java.lang.String'. Binding should be configured manually using converter.

O erro está ocorrendo porque TextField precisa de String. Ele não sabe lidar com List.

No final do erro diz ainda para usar um conversor para fazer o bind.

Ou seja, precisa de um conversor pra transformar List<String> em String.

kk…mais nunca que eu vou conseguir fazer isso…rs

Olhei o artigo, cheguei a tentar a fazer, mas tenho varias duvidas

nessa iimagem, esse código é o conversor, certo? Então copiei ele e fiz as alterações e ele ficou assim: dentro do mesmo pacote que a classe Venda

package br.com.fjsistemas.backend;

import java.util.List;
import java.util.Locale;

import org.springframework.core.convert.ConversionException;

import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.type.TypeFactory;
import com.fasterxml.jackson.databind.util.Converter;

public class StringToNameConverter implements Converter<String, Venda> {
	
  public Venda convertToModel(String text, Locale locale)
      throws ConversionException {
    if (text == null) {
      return null;
    }
    String[] parts = text.split(" ");
    if (parts.length != 2) {
      throw new ConversionException(text) {

		private static final long serialVersionUID = 1L;
	};
    }
    return new Venda();
  }

  public List<String> convertToPresentation(Venda venda, Locale locale)
      throws ConversionException {
    if (venda == null) {
      return null;
    } else {
      return venda.getDescricao();
    }
  }

  public Class<Venda> getModelType() {
    return Venda.class;
  }

  public Class<String> getPresentationType() {
    return String.class;
  }

@Override
public Venda convert(String value) {
	// TODO Auto-generated method stub
	return null;
}

@Override
public JavaType getInputType(TypeFactory typeFactory) {
	// TODO Auto-generated method stub
	return null;
}

@Override
public JavaType getOutputType(TypeFactory typeFactory) {
	// TODO Auto-generated method stub
	return null;
}
}

agora neste segunda trecho de código eu não entendi se é uma outra classe, se é a continuacao do conversor ou se devo colocar isso na view

RoinujNosde · Abril 29, 2021, 7:46pm

Converter errado.
Tem que ser esse:
com.vaadin.data.Converter

Você pode apagar esses métodos.
A implementação do Converter tem que ser nos métodos com @Override.

No convertToPresentation você vai pegar uma Lista de String e converter em String:
Exemplo:

public Result<String> convertToPresentation(List<String> value, ValueContext context) {
    return Result.ok(value.toString());
}

No convertToModel pega uma String e converte pra Lista de String.

O erro ainda está ocorrendo porque apesar de ter criado um Converter (incompleto, por sinal), você não tá usando ele. Tem que colocar ele na view:

binder.forField(campoDaDescricaoAqui).withConverter(new StringToNameConverter());
