我使用的是PrimeFaces 5.0。
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显示一些其他信息需要它,一切似乎都很好,问题是当我获得数据并选择时,这些数据并没有在属性上设置它。。。
自动完成项目提示:
<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>
这是我要用的转换器。(我在这里做了一些测试,一切似乎都正常。(
public class converterOC implements Converter {
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;
}
}
public String getAsString(FacesContext fc, UIComponent uic, Object object) {
if (object != null) {
return String.valueOf(object);
} else {
return null;
}
}
实体:

在自动完成的同一行,我有一个命令按钮。假设它在控制台上打印我在自动完成上设置的属性中的一个数据,但它什么也没显示。
public void seleccionarorden() {
System.out.println(getEncabezado_encontrado().getValorivacv());
System.out.println(Encabezado_encontrado.getValorivacv());
}
我尝试了我脑海中的一切,但我的想法都用完了
页面上显示的内容
这就是控制台显示的内容。甚至不是例外:
控制台显示的内容
感谢您的帮助。。我让它工作
就是这样运作的
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更改了项目选择事件的<p:CommandButton />
(
<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}"
converter="converterOC" 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:ajax event="itemSelect" listener="#{c_ordenCompra.seleccionarorden}" update="noc,date,acs,acb,soli,prov,ter,nreg,dtdetalles" />
</p:autoComplete>
p:autoComplete
的属性itemValue="#{orden.idencacv}"
是指orden
的属性,该属性是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}"
