In order not to escape the scope of the previous question: Displayed product is the lower within the group (Criteria)

The issue apparently appeared to be resolved, although we were unable to verify that it was indeed correct due to an exception error in the conversion class

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;

import br.com.modelo.Lote;
import br.com.repository.Lotes;
import br.com.util.cdi.CDIServiceLocator;

@FacesConverter(forClass = Lote.class)
public class LoteConverter implements Converter {

//@Inject
private Lotes lotes;

public LoteConverter() {
    lotes = CDIServiceLocator.getBean(Lotes.class);
}

@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {

    Lote retorno = null;

    if (value != null) {
        String id = new String(value);
        retorno = lotes.porId(id);
    }

    return retorno;
}

@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
    if (value != null) {
        Lote lote = (Lote) value;
        return lote.getLote() == null ? null : lote.getLote();
    }

    return "";
}

}

The error line is as follows:

@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
    if (value != null) {
        Lote lote = (Lote) value; << Linha 38
        return lote.getLote() == null ? null : lote.getLote();
    }

    return "";
}

Any suggestions on how to solve?

Bring value from a grouped record I have doubts if this would be the correct way to make a connection using the class PDO

See this example

@Override
public Object getAsObject(FacesContext fc, UIComponent uic, String value) {
    if (value != null && !"".equals(value) && !(value.isEmpty())) {
        try {
            EntidadesDaoImp daoImp = new EntidadesDaoImp();
            Entidade entidade = new Entidade();

            entidade = daoImp.pesquisarId(Integer.parseInt(value));

            return entidade;
        } catch (NumberFormatException e) {
            throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Erro de Conversão", "O Valor não é válido."));
        }
    } else {
        return null;
    }
}

@Override
public String getAsString(FacesContext fc, UIComponent uic, Object object) {
    if (object != null && !"".equals(object)) {
        return String.valueOf(((Entidade) object).getId());
    }
    return null;

}

Hello, try this.

@Override
    public String getAsString(FacesContext fc, UIComponent uic, Object object) {
        if (object != null && !"".equals(object)) {
            return String.valueOf(((Lote) object).getId());
        }
        return null;

    }
