如何更新dataTable celleditor的行

Question

我正在尝试使用单元格编辑来实现primefaces数据表。

  <p:dataTable id="table" var="data" value="#{bean.liste}"
                     editable="true" 
                     editMode="cell" 
                     widgetVar="cellInter"
                     styleClass="hovered striped table tblDataTable" >          
            <p:ajax event="cellEdit" listener="#{bean.onCellEdit}"   />            
             <p:column  sortBy="#{data.type}" filterBy="#{data.type}"    filterMatchMode="contains"  >
                <f:facet name="header">
                    <span class="nomColonneTab"  >Type  </span>
                </f:facet>
                <p:cellEditor>                
                    <f:facet name="output">               
                        <p:outputLabel value="#{data.type}"/> 
                    </f:facet>
                    <f:facet name="input">
                        <h:inputText value="#{data.type}" />
                    </f:facet>
                </p:cellEditor> 
            </p:column>

但是当我点击数据表来更改类型的值时它不会改变

这是我的功能：

  public void onCellEdit(CellEditEvent event) {
        Object oldValue = event.getOldValue();
        Object newValue = event.getNewValue();

        if (newValue != null && !newValue.equals(oldValue)) {
            FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Cell Changed", "Old: " + oldValue + ", New:" + newValue);
            FacesContext.getCurrentInstance().addMessage(null, msg);


        }               
    }
