不知道为什么 RPCDataServiceAdapter 会弹出错误。有一部分脚本与错误相关。
public function normalusercontactdatagrid_creationCompleteHandler(event:FlexEvent):void
{
getAllNormaluserResult.token = normaluserService.getAllNormaluser();
}
protected function addUSER(event:MouseEvent):void
{
var win:IFlexDisplayObject =PopUpManager.createPopUp(this, addUser, true) as IFlexDisplayObject;
PopUpManager.centerPopUp(win);
var e:FlexEvent;
normalusercontactdatagrid_creationCompleteHandler(e);
}
但显示以下数据适配器错误
TypeError: Error #1009: Cannot access a property or method of a null object reference.

第 80 行、第 93 行和第 172 行的错误
是
line 80 getAllNormaluserResult.token = normaluserService.getAllNormaluser();
line 93 normalusercontactdatagrid_creationCompleteHandler(e);
line 172 <mx:LinkButton label="Add" click="addUSER(event);"/>
如果我正确理解错误堆，我认为这些行会触发 dataService 中的错误，即
at _Super_NormaluserService/getAllNormaluser()[C:\Users\School\Adobe Flash Builder 4.6\FYPadminSideV3\src\services\normaluserservice\_Super_NormaluserService.as:244]
这怎么可能发生？我该怎么办？
我发现如果我不在弹出窗口中调用 adduser.mxml ，错误将不会再次显示。adduser.mxml 如下所示
