<p:commandButton id="btnAddEntry" value="Add new row" actionListener="#{myBean.addNewCar}" ... update="carTable growl" process="@this carTable ..."/>

<p:dataTable id="carTable" var="car" value="#{myBean.cars}" ... editable="true">  
        <p:column ...>  
            <p:cellEditor>
                ...
            </p:cellEditor>  
        </p:column>
    ...
        <p:column ...>  
                <p:rowEditor />  
        </p:column>
    ...         
</p:dataTable>

这是我目前为bean方法所做的：

public void addNewCar() {

    Car newCar = new Car();
    cars.add(newCar);

    FacesContext facesContext = FacesContext.getCurrentInstance();
    UIComponent uiTable = ComponentUtils.findComponent(facesContext.getViewRoot(),"carTable");
    DataTable table = (DataTable) uiTable;

    final AjaxBehavior behavior = new AjaxBehavior();    
    RowEditEvent rowEditEvent = new RowEditEvent(uiTable,behavior,table.getRowData());
    rowEditEvent.setPhaseId(PhaseId.UPDATE_MODEL_VALUES);
    table.broadcast(rowEditEvent);
}

我不知道
