Question

当我从数据表中选择一行时，我有一个对话框来更改设备类型。第一个对话框打开没有问题，我可以正常更换设备。

当我点击“保存”时，我打开另一个对话框以确认更改。在这个新对话框中，id为“confirmarSim”的按钮应调用辅助bean方法。问题是永远不会调用方法，但会执行不完整的方法（两个对话框都会关闭）。

代码如下：

<p:dialog header="Editar IP Cadastrado" id="dialog" styleClass="borderless" widgetVar="dlgEditar" modal="true" showEffect="fade" hideEffect="fade" resizable="false" draggable="false" closable="false">

        <p:growl id="growlInformacao" sticky="true" />

        <p:panelGrid columns="2" rendered="#{not empty cadastrosIPsBean.selectedCadastro}" style="font-size: 14px">

            <p:outputLabel value="Equipamento:"/>
            <p:selectOneMenu id="selecionadorEquipamento" value="#{cadastrosIPsBean.selectedCadastro.equipamento}" style="width: 92%">
                <f:selectItems value="#{cadastrosIPsBean.listaEquipamentosFormatada}"/>
            </p:selectOneMenu>

            <br/>
            <br/>

            <f:facet name="footer">

                <p:commandButton value="Save" id="btConfirmar" oncomplete="PF('dlgConfirmar').show()" update=":form:tbl" style="width: 125px">
                    <p:dialog appendTo="@(body)" header="Confirmar alterações" id="confirmar" widgetVar="dlgConfirmar" modal="true" showEffect="fade" hideEffect="fade" resizable="false" draggable="false">
                        <br/>
                        <p:outputLabel value="Tem certeza de que deseja salvar as alterações?" style="font-size: 14px"/>
                        <br/>
                        <br/>
                        <f:facet name="footer">
                            <p:commandButton id="confirmarSim" value="Yes" process="tbl" oncomplete="PF('dlgConfirmar').hide(); PF('dlgEditar').hide()" actionListener="#{cadastrosIPsBean.salvarAlteracoes()}" update=":form:growlInformacao" style="font-size: 14px; width: 100px"/>
                            <p:spacer width="20"/>
                            <p:commandButton id="confirmarCancelar" value="Cancel" process="tbl" oncomplete="PF('dlgConfirmar').hide()" actionListener="#{cadastrosIPsBean.atualizaListasUltimosCadastros()}" update=":form:tbl" style="font-size: 14px; width: 100px"/>
                        </f:facet>
                    </p:dialog>
                </p:commandButton>

                <p:spacer width="20"/>

                <p:commandButton value="Close" id="btFechar" oncomplete="PF('dlgDescartar').show()" action="#{cadastrosIPsBean.atualizaListasUltimosCadastros()}" update=":form:tbl" style="width: 125px">
                    <p:dialog appendTo="@(body)" header="Descartar alterações" id="descartar" widgetVar="dlgDescartar" modal="true" showEffect="fade" hideEffect="fade" resizable="false" draggable="false">
                        <br/>
                        <p:outputLabel value="Tem certeza de que deseja descartar as alterações?" style="font-size: 14px"/>
                        <br/>
                        <br/>
                        <f:facet name="footer">
                            <p:commandButton id="fecharSim" value="Sim" process="tbl" oncomplete="PF('dlgDescartar').hide(); PF('dlgEditar').hide()" action="#{cadastrosIPsBean.atualizaListasUltimosCadastros()}" update=":form:tbl" style="font-size: 14px; width: 100px"/>
                            <p:spacer width="20"/>
                            <p:commandButton id="fecharCancelar" value="Cancelar" process="tbl" oncomplete="PF('dlgDescartar').hide()" action="#{cadastrosIPsBean.atualizaListasUltimosCadastros()}" update=":form:tbl" style="font-size: 14px; width: 100px"/>
                        </f:facet>
                    </p:dialog>
                </p:commandButton>

            </f:facet>

        </p:panelGrid>

</p:dialog>

其余代码运行良好，只是id =“confirmarSim”的按钮不会调用辅助bean方法"#{cadastrosIPsBean.salvarAlteracoes()}"。

为什么不调用此方法？

您需要将对话框放在主<h:form></h:form>之外，并将每个对话框插入其他表单中。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html>
