我正在使用 PrimeFaces、JPA、Hibernate 和 JSF 2.0 开发一个 Web 应用程序。

我有这个JSF页面，“保存”和“取消”p:commandButton都没有动作！你能帮忙吗？

in中的操作 ( action="#{lotController.initLot}")重定向到此页面：p:commandButtonaction="#{lotController.initLot}"

<h:body style="width:600px; ">
<ui:composition template="/common/master-layout.xhtml">
    <ui:define name="title">#{message['app.page.main.title']}</ui:define>
    <ui:debug
        rendered="#{initParam['javax.faces.PROJECT_STAGE'] eq 'Development'}"
        hotkey="x" />
    <ui:define name="content">

        <p:fieldset legend="Création d'un nouveau lot"
            style="margin-top: 20px;">

            <h:form id="addLotForm">

                <p:fieldset legend="Lots techniques" toggleable="true"
                    toggleSpeed="500"
                    style="margin-left: 10px; margin-top: 30px; background-color:RGB(225,240,233)">

                    <h:panelGrid columns="2" cellpadding="10">
                        <h:outputText value="Libellé" style="font-weight:bold" />
                        <p:inputText value="#{lotController.lotToSave.libelle}" />
                    </h:panelGrid>

                </p:fieldset>

                <!-- Descriptifs -->
                <p:fieldset legend="Descriptifs" toggleable="true"
                    toggleSpeed="500"
                    style="margin-left: 10px; margin-top: 30px; background-color:RGB(225,240,233)">

                    <h:panelGrid columns="2" cellpadding="10">
                        <h:outputText value="Libellé" style="font-weight:bold" />

                            <f:selectItems value="#{lotController.listDescriptifs}" var="descriptif"
                                itemLabel="#{descriptif.libelle}" itemValue="#{descriptif}" />
                        </p:selectOneMenu>

                    </h:panelGrid>

                </p:fieldset>

                <p:commandButton value="Save" id="saveLot"

控制器：

}

protected LotDto prepareDtoBeforeSave() {
    LotDto lot = new LotDto();
    lot.setIdDescriptif(selectedDescriptif);
    lot.setLibelle(lotToSave.getLibelle());
    return lot;
}

谢谢你们。

我解决了这个问题，我忘了为我的转换器生成 hashCode() 和 equals() 方法。
