Question

我正在使用JSF 2.0和Primefaces 3.4.2

我有一个弹出式对话框，其中我有inputText，selectOneMenu，autoComplete和<p:commandButton

我在selectOneMenu <p:ajax update="dept" listener="#{empMB.loadDepartments}" />

中有以下内容

当我单击commandButton时，将调用selectOneMenu的listener和Converter类。我没有调用commandButton的方法。这可能是什么原因？

JSF代码

    <p:dialog header="My Panel" style="font-weight:bold"
                    widgetVar="NewDialog" resizable="false" id="NewDlg"

                    modal="true" position="center top" width="850" height="450">
                    <h:form id="createform">                    
                    <p:panelGrid   columns="6">         

                        <h:outputLabel value="Employee # " for="emp" />
                        <p:autoComplete value="#{mymb.selectedEmployee}"
                            id="emp" minQueryLength="3"

                            forceSelection="true" >                           
                             <p:ajax event="itemSelect" listener="#{mymb.handleSelect}"

</p:selectOneMenu>

                <p:commandButton value="Save" icon="ui-icon-check" style="margin:0" 
                actionListener="#{empMB.saveRequest}" />

                    </h:form>
                   </p:dialog>

当您处理整个表单（例如部门或其他部门）时，JSF可能无法设置某个字段。也许类型错了，或转换器失败。在表单中添加p:message并在没有process="@this"的情况下更新它，您可能会看到一些内容。

commandButton actionListener调用selectOneMenu侦听器
