Question

查看：

    <h:form>
<p:dataTable rows="10" id="analysisListTable" value="#{analyses}" var="anl" resizableColumns="true" editable="true" editMode="cell">

    <p:ajax event="cellEdit" listener="#{analysisBean.onCellEdit}" />

    <p:column headerText="Aktif" footerText="Aktif" sortBy="#{anl.active}" width="40" styleClass="TexAlCenter">
        <p:cellEditor>
            <f:facet name="output">
                <h:outputText value="#{anl.active?' Evet':' Hayır'}"/>
            </f:facet>
            <f:facet name="input">
                <h:selectBooleanCheckbox value="#{anl.active}" title="Aktif"></h:selectBooleanCheckbox>
            </f:facet>
        </p:cellEditor>
    </p:column>

动作：

@Stateful
@Name("analysisBean")
@Scope(ScopeType.SESSION)
public class AnalysisBean implements AnalysisBeanInterface {

@PersistenceContext
private EntityManager em;

@DataModel
private List<Analysis> analyses;

@DataModelSelection
@Out(required=false)
private Analysis analysis;


@Factory("analyses")
public void findAnalyses(){
    analyses = em.createQuery("select anl from Analysis anl").getResultList();
}


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

    System.out.println(analysis.title + " > Active = " + analysis.isActive() + " olarak kaydedildi.");
}

当我运行服务器时，DataTables带有数据。当我点击一个单元格时，它会从outputText更改为selectBooleanCheckbox。但是，当我更改时，它不会调用操作onCellEdit。

Answer 1

你应该尝试＆＃34; AjaxBehaviourEvent＆＃34;而不是＆＃34; CellEditEvent＆＃34;你可以再次在功能中投射它。这解决了我遇到的类似问题。

p：dataTable cellEdit Ajax调用不会调用操作
