我有問題更新其他行在同一datatable當一行更新使用primeface數據表單內編輯ajax rowEdit。
但未能通過ajax調用更新其他行。 ajax響應僅返回已更新的相同行數據。Primefaces數據表單內編輯以更新同一數據表中的其他行與ajax rowEdit事件處理
的代碼如下：
<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testBean就：
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;
}
}
Ajax響應體：
