Question

我遇到的问题是h：commandLink放在p：dataTable的一列中。不调用action方法。我正在使用primefaces 2.21和jsf 2.0。像这样的代码：

    <ui:define name="center">
        <h:form id="form1">
            <p:dataTable id="userDataTable"
                 value="#{adminstratorBean.periodicalUsers}" var="user"
                paginator="true" rows="10"
                paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
                rowsPerPageTemplate="5,10,15">
                <f:facet name="header">  
                        Ajax Pagination   
                    </f:facet>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Id" />
                    </f:facet>
                    <h:outputText value="#{user.id}"></h:outputText>
                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Name" />
                    </f:facet>
                    <h:outputText value="#{user.name}"></h:outputText>

                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Password" />
                    </f:facet>
                    <h:outputText value="#{user.password}"></h:outputText>

                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Sex" />
                    </f:facet>
                    <h:outputText value="#{user.sex}"></h:outputText>

                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Email" />
                    </f:facet>
                    <h:outputText value="#{user.mail}"></h:outputText>

                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Phone" />
                    </f:facet>
                    <h:outputText value="#{user.phone}"></h:outputText>

                </p:column>
                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Birthday" />
                    </f:facet>
                    <h:outputText value="#{user.birthday}">
                        <f:convertDateTime type="date"></f:convertDateTime>

                <p:column>
                    <f:facet name="header">
                        <h:outputText value="Delete" />
                    </f:facet>
                    <h:commandLink value="#{msgs.delete}"
                        actionListener="#{adminstratorBean.deleteUser(user)}">
                    </h:commandLink>
                </p:column>
            </p:dataTable>
        </h:form>
    </ui:define>

Answer 1

使用action代替actionListener：

<h:commandLink value="#{msgs.delete}"
     action="#{adminstratorBean.deleteUser(user)}">
</h:commandLink>

无法使用参数调用actionListener，并且在业务逻辑执行之前（在您的操作方法中）使用。

Answer 2

你应该使用＆LT;号码：commandLink＆GT; 代替＆LT; H：commandLink＆GT; 在里面＆LT;号码：。的dataTable＆GT;

commanLink在p：dataTable中不起作用
