Ne sait pas pourquoi le RPCDataServiceAdapter peut afficher une erreur. Il y a une partie du script liée à l'erreur.Erreur DataAdapter
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);
}
Mais l'erreur DataAdapter suivant apparaît
TypeError: Error #1009: Cannot access a property or method of a null object reference.

sont

line 172 <mx:LinkButton label="Add" click="addUSER(event);"/>
Si je comprends la pile d'erreur correctement , Je pense que ces lignes déclenchent les erreurs du dataService qui est
at _Super_NormaluserService/getAllNormaluser()[C:\Users\School\Adobe Flash Builder 4.6\FYPadminSideV3\src\services\normaluserservice\_Super_NormaluserService.as:244]
Comment cela est-il possible? et que dois-je faire?
Je découvre que si je n'appelle pas adduser.mxml dans la fenêtre pop-up, l'erreur ne s'affichera plus. et la adduser.mxml se présente comme suit

Que se passe-t-il à l'autre extrémité de la requête RPC? Et cela arrive seulement parfois - pas à chaque fois? – ethrbunny
Cela se produit uniquement lorsque j'appelle le formulaire adduser.mxml la fonction addUSER. et à l'autre extrémité de la requête RPC est un script PHP. – Samuel
