Question

在我点击页面中的“保存”后引入验证后，没有任何反应。在页面中，我有“保存”和“取消”。我将“immediate = true”设置为取消按钮，这样就不会执行任何验证并返回上一个视图。当我点击保存时，执行验证并正确显示错误，但是如果/当我输入正确的输入（以便验证没有错误），而不是处理数据并返回到上一页，没有任何反应...

我错过了什么吗？

这里有一些代码片段：

查看：

<f:metadata>
  <f:viewParam name="mode" value="#{roomDetailController.model.mode}"/>
  <f:viewParam name="dbId" value="#{roomDetailController.model.dbId}"/>

  <f:event listener="#{roomDetailController.processCommand}" type="preRenderView"/>
</f:metadata>

...

<tr>
  <td>
    <h:outputLabel value="#{msg.roomFormFieldRoomName}:"/>
  </td>
  <td>
    <h:inputText id="roomName" value="#{detailModel.afterObject.roomName}" disabled="#{detailModel.mode == detailModel.viewMode}">
      <f:validateBean/>
    </h:inputText>
    <h:message for="roomName" style="color:red"/><br/>
  </td>
</tr>
<tr>
  <td>
    <h:outputLabel value="#{msg.roomFormFieldRoomIPs}:"/>
  </td>
  <td>
    <h:inputText id="roomIPs" value="#{detailModel.afterObject.roomIPs}" disabled="#{detailModel.mode == detailModel.viewMode}">
      <f:validateBean/>
    </h:inputText>
    <h:message for="roomIPs" style="color:red"/><br/>
  </td>
</tr>

...

<!-- SUBMIT BUTTON -->
<h:commandButton
  styleClass     = "waiButton"
  value          = "#{commonButtonSubmit}"
  action         = "#{detailController.submitAction()}"
  rendered       = "#{detailModel.mode != detailModel.viewMode}"
/>

<!-- CANCEL BUTTON -->
<h:commandButton
  styleClass = "waiButton"
  value      = "#{commonButtonCancel}"
  action     = "#{detailController.cancelAction()}"
  immediate  = "true"
  rendered   = "#{detailModel.mode == detailModel.cancelMode or detailModel.mode == detailModel.editMode or detailModel.mode == detailModel.multiEditMode or detailModel.mode == detailModel.createMode}"
/>
...

控制器：

...
// Action: "submit" clicked
public String submitAction()
{
  detailModel.setCommand( DetailModel.Command.SUBMIT );
  return null;
}

// Action: "cancel" clicked
public String cancelAction()
{
  if ( detailModel.getEditMode().equals( detailModel.getMode() ) )
  {
    detailModel.setMode( detailModel.getViewMode() );
    return null;
  }
  else
  {
    // Multi Edit Mode
    return appendUrlParameter( getListViewName(), FACES_REDIRECT_TRUE );
  }
}
...

问题解决了。如上所述它与验证无关。

Bean验证没有任何影响
