Jsf 从p获取数据：使用转换器自动完成

我用的是PrimeFaces5.0

我试图做的是在BD上的1p:autocomplete1外观的帮助下，返回建议并使用itemtip显示需要它的其他信息，一切似乎都很好，问题是当我获得数据并选中时，这些数据没有在属性上设置它

使用itemtip自动完成：

<p:row>
    <p:column colspan="10">
        <p:outputLabel value="Orden de Compra "/>
        <p:autoComplete id="itemTip" value="#{c_ordenCompra.encabezado_encontrado}" 
                        completeMethod="#{c_ordenCompra.completarOrdenCpra}"
                        var="orden" itemLabel="#{orden.numdocucv}" itemValue="#{orden.idencacv}" 
                        converter="themeConverter" forceSelection="true">
            <f:facet name="itemtip">
                <h:panelGrid columns="2" cellpadding="3" cellspacing="5">
                    <h:outputText value="Fecha" />
                    <h:outputText value="#{orden.fechadoctocv}" />

                    <h:outputText value="Sucursal" />
                    <h:outputText value="#{orden.tbsucursalesByFkencacvsucurentra.nomsucur}" />

                    <h:outputText value="Proveedor" />
                    <h:outputText value="#{orden.tbpersonasrelaByIdpersorelaprove.nomcompleto}" />
                </h:panelGrid>
            </f:facet>

        </p:autoComplete>
        <p:commandButton value="buscar" actionListener="#{c_ordenCompra.seleccionarorden()}"/>
    </p:column>
</p:row>

实体：

public class Tbencacv implements java.io.Serializable {

private String nomuser;
private Set<Tbdetacv> tbdetacvs = new HashSet<Tbdetacv>(0);

public Tbencacv() {
}
//all setters and getters

我想尽了一切办法，但我没有办法了

这是控制台显示的内容。甚至不例外：

---

属性

itemValue=“#{orden.idencacv}”

的

p:autoComplete

引用

orden

的属性，即

Tbencacv

对象。你应该把它当作一个物体

将

p:autoComplete

的

itemValue=“#{orden.idencacv}”更改为
itemValue=“#{orden}”

请参阅Java EE教程
谢谢您的帮助。。我让它工作

这就是它的工作原理

编辑：转换器

@FacesConverter("converterOC")
public class converterOC implements Converter {
    @Override
    public Object getAsObject(FacesContext fc, UIComponent uic, String value) {
        if (value != null && value.trim().length() > 0) {
            try {
                M_encacv modelo_encacv = new M_encacv();
                Tbencacv encav_encontrado = modelo_encacv.Ordene1CompraEncacv(value);
                return encav_encontrado;
            } catch (NumberFormatException e) {
                throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Conversion Error", "Not a valid theme."));
            }
        } else {
            return null;
        }
    }

    @Override
    public String getAsString(FacesContext fc, UIComponent uic, Object object) {
        if(object != null) {
            return String.valueOf(((Tbencacv) object).getIdencacv());
        }
        else {
            return null;
        }
    }
}

编辑：自动完成（我使用ajax更改了itemselect事件的
）


我做到了，但仍然没有得到数据集。。。可能是转换器吗？请确保ManagedBean中的属性可以使用getter/setter方法，这篇文章可能会对您有所帮助
 public void seleccionarorden() {
    System.out.println(getEncabezado_encontrado().getValorivacv());
    System.out.println(Encabezado_encontrado.getValorivacv());
}

@FacesConverter("converterOC")
public class converterOC implements Converter {
    @Override
    public Object getAsObject(FacesContext fc, UIComponent uic, String value) {
        if (value != null && value.trim().length() > 0) {
            try {
                M_encacv modelo_encacv = new M_encacv();
                Tbencacv encav_encontrado = modelo_encacv.Ordene1CompraEncacv(value);
                return encav_encontrado;
            } catch (NumberFormatException e) {
                throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Conversion Error", "Not a valid theme."));
            }
        } else {
            return null;
        }
    }

    @Override
    public String getAsString(FacesContext fc, UIComponent uic, Object object) {
        if(object != null) {
            return String.valueOf(((Tbencacv) object).getIdencacv());
        }
        else {
