primefaces rowEdit仅当事件成功时才更新表的事件

Question

我正在调用rowEdit事件，并且仅当事件成功执行数据库更新时才想刷新表。以下是我的代码。

XHTML

<p:dataTable id="xobjTable" var="xobj" value="#{xListView.xListResponseObject}" 
           scrollRows="20" scrollable="true" liveScroll="true" scrollHeight="600" 
           rowKey="#{xobj.X}" 
           selection="#{xListView.selectedObject}" selectionMode="single" 
           style="margin-top: 20px; margin-bottom:20px" editable="true"> 

         <f:facet name="header"> 
          Search Results 
          <p:spacer width="20"/> 
          <h:commandLink id="csv"> 
           <p:graphicImage value="csv.png" width="24"/> 
           <p:dataExporter type="csv" target="xobj" fileName="xListSearch" /> 
           <p:tooltip id="toolTipFade" for="csv" value="Click on CSV to download entire table as a csv file. " /> 
          </h:commandLink> 
         </f:facet> 
         <p:ajax event="rowEdit" listener="#{xListView.onRowEdit}" update=":xListform:xobjTable" /> 
         <p:column headerText="X" style="width:60px;text-align: center">

           </f:facet> 
           <f:facet name="input"> 
            <h:selectOneMenu value="#{xobj.active}"> 
             <f:selectItems value="#{xListView.activeList}" /> 
            </h:selectOneMenu> 
           </f:facet> 
          </p:cellEditor> 
         </p:column> 
         <p:column headerText="Location" style="width:160px;text-align: center"> 
          <p:cellEditor> 
           <f:facet name="output"> 
            <h:outputText value="#{xobj.location}"/> 
           </f:facet> 
           <f:facet name="input"> 
            <p:inputText id="location" value="#{xobj.location}" /> 
           </f:facet> 
          </p:cellEditor> 
         </p:column> 
         <p:column headerText="State" style="width:160px;text-align: center"> 
          <p:cellEditor> 
           <f:facet name="output"> 
            <h:outputText value="#{xobj.state}"/> 
           </f:facet> 
           <f:facet name="input"> 
            <p:inputText id="state" value="#{xobj.state}" />

         </p:column> 
         <p:column headerText="x Country Code" style="width:160px;text-align: center"> 
          <p:cellEditor> 
           <f:facet name="output"> 
            <h:outputText value="#{xobj.xCountryCode}"/> 
           </f:facet> 
           <f:facet name="input"> 
            <p:inputText id="xCountryCode" value="#{xobj.xCountryCode}" /> 
           </f:facet> 
          </p:cellEditor> 
         </p:column> 
         <p:column headerText="xrarier" style="width:160px;text-align: center">

           <f:facet name="output"> 
            <h:outputText value="#{xobj.carrier}"/> 
           </f:facet> 
           <f:facet name="input"> 
            <h:selectOneMenu value="#{xobj.carrier}"> 
             <f:selectItems value="#{xListView.xarrierList}" /> 
            </h:selectOneMenu> 
           </f:facet> 
          </p:cellEditor> 
         </p:column> 
         <p:column style="width:32px" headerText="Edit" rendered="#{allTabs.isShow(xListView.title)}"> 
          <p:rowEditor /> 
         </p:column> 
         <p:column style="width:160px;text-align: center" rendered="#{allTabs.isShow(xListView.title)}" headerText="Delete"> 
          <p:commandButton id="deleteDid" actionListener="#{xListView.deletexy(xobj)}" 
              icon="ui-icon ui-icon-trash red" title="Delete" update="@form"> 
           <p:confirm header="Confirmation" message="#{xListView.finalDeleteMessage}" icon="ui-icon-alert" /> 
          </p:commandButton> 
         </p:column> 
        </p:dataTable> 

下面是事件方法

public void onRowEdit(RowEditEvent event) { 
     xListResponseObject editObject = (xListResponseObject) event.getObject(); 
     logger.debug("Coming to edit the row."); 
     String editXYStatus = xListDAO.editxy(editObject); 
     if (editxyStatus.equals(SUCCESS_RESPONSE)) { 
      FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "INFO", "X/Y edit successful!"); 
      FacesContext.getCurrentInstance().addMessage(null, msg); 
     } else { 
      FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, "INFO", "X/Y edit failed :" + editxyStatus); 
      FacesContext.getCurrentInstance().addMessage(null, msg); 
     } 

    } 

我想发生这样的更新，只有当rowEdit事件更新数据库。 我可以在我的方法中有一个布尔值集并访问p：ajax中更新的数据吗？

Answer 1

添加到结束你SUCCESS_RESPONSE

RequestContext.getCurrentInstance().update("form:npaobjTable"); 

或任何你的表真正的ID是。

我遇到了同样的问题。 URL下方将解决您的问题。 。

实际响应：

public void onRowEdit(RowEditEvent event) { 
     NpaListResponseObject editObject = (NpaListResponseObject) event.getObject(); 
     logger.debug("Coming to edit the row."); 
     String editNpaNxxStatus = npaListDAO.editNpaNxx(editObject); 
     if (editNpaNxxStatus.equals(SUCCESS_RESPONSE)) { 
      FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "INFO", "NPA/NXX edit successful!"); 
      FacesContext.getCurrentInstance().addMessage(null, msg); 
     } else { 
      FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, "INFO", "NPA/NXX edit failed :" + editNpaNxxStatus); 
      FacesContext.getCurrentInstance().addMessage(null, msg); 
      FacesContext.getCurrentInstance().validationFailed(); 
     } 

    } 

加入FacesContext.getCurrentInstance（）validationFailed（）;最后在失败的情况下。
