Question

我有数据表和xhtml中的下拉列表。如果我在这个页面中删除p：datatable代码，那么我可以调用dropdown的valueChangeListener，但是如果p：datatable存在于xhtml中，那么我就无法调用它。

Xhtml代码

<ui:define name="content">
    <f:view>

                <f:selectItem itemLabel="Send to Underwriter" itemValue="B" />

            </h:selectOneMenu>
        </h:form>
    </f:view>
</ui:define>

听众代码是

    public void DoPathProcessing1(ValueChangeEvent event) {
    String newValue = (String) event.getNewValue();
    System.out.println("Path"
            + certActListModel.getRowData().getRoutePathCd());
    certActListModel.getRowData().setRoutePathCd(newValue);

    System.out.println("value is " + newValue);
}

知道为什么它不起作用吗？

我正在使用jsf-api-2.0.3和primefaces-2.2.1

您正在使用下拉组件的value和valueChangeListener属性。你为什么要这样做？

只需让value="#{reqSummaryHandler.certNumber}在托管bean中调用setCertNumber(String certNumber)即可。为什么不把这段代码放入setter方法？

Dropdown的valueChangeListener不使用primefaces数据表
