当使用datatable datatable in-cell edit ajax primeface更新一行时，我有同步rowEdit更新其他行的问题。
但无法使用ajax调用更新其他行。 ajax响应仅返回已更新的相同行数据。

代码如下：

<h:form id="testForm">
    <p:dataTable id="testDT" var="d" rowIndexVar="rowIndex"
        value="#{testBean.lists}" editable="true">
        <p:column>
            <f:facet name="header">No</f:facet>
            <h:outputText value="#{rowIndex}" />
        </p:column>
        <p:column headerText="Value">
            <p:cellEditor>
                <f:facet name="output">
                    <h:outputText value="#{d.value}" />
                </f:facet>
                <f:facet name="input">
                    <p:inputText value="#{d.value}" size="5" />
                </f:facet>
            </p:cellEditor>
        </p:column>
        <p:column headerText="Edit" style="width:50px">
            <p:outputPanel rendered="#{d.editable}">
                <p:rowEditor>
                </p:rowEditor>
            </p:outputPanel>
        </p:column>
        <p:ajax event="rowEdit" update=":testForm:testDT"
            listener="#{testBean.onRowUpdate}" />
    </p:dataTable>
    </h:form>

我的TestBean：

package web.bean.test;

  import java.util.ArrayList;
  import java.util.List;

  import javax.annotation.PostConstruct;
  import javax.faces.bean.ManagedBean;
  import javax.faces.bean.ViewScoped;

  import org.primefaces.event.RowEditEvent;

  @ManagedBean(name="testBean")
  @ViewScoped
  public class TestBean {
private List<TestData> lists = new ArrayList<>();

@PostConstruct
    protected void init() {
    TestData d = new TestData("Row1Data", 1d, true);
        lists.add(d);
    d = new TestData("Row1Data", 11.11d, false);
    lists.add(d);
}

public void onRowUpdate(RowEditEvent event) {
    Object o = event.getObject();
    if (o != null) {
        TestData d = (TestData)o;
        TestData d1 = lists.get(1);
        d1.setValue(d1.getValue() + d.getValue());
    }
}

public List<TestData> getLists() {
    return lists;
}

public void setLists(List<TestData> lists) {
    this.lists = lists;
}
 }

 package web.bean.test;

 public class TestData {
private String name;
private double value;
private boolean editable;

public TestData(String name, double value, boolean editable) {
    super();
    this.name = name;
    this.value = value;
    this.editable = editable;
}
public TestData() {
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public double getValue() {
    return value;
}
public void setValue(double value) {
    this.value = value;
}
public boolean isEditable() {
    return editable;
}
public void setEditable(boolean editable) {
    this.editable = editable;
}


 }

将ajax事件调度程序放在rowEditor的一侧并使用@all引用。

<p:rowEditor>
  <p:ajaxStatus update="@all" listener="#{testBean.onRowUpdate}"/>
</p:rowEditor>
