Examples for reading & writing appData

Example of update appData

    private function updateData():void
   {
       var dr:DataRequest = container.newDataRequest();
       dr.add(dr.newUpdatePersonAppDataRequest("VIEWER", "testdatakey1", 'test'));
       dr.send(updatePersonAppDataCallback);
   }
   
       private function updatePersonAppDataCallback(dataResp:DataResponse):void
       {
               Alert.show("updatePersonAppDataCallback().  \n dataResp.hadError()=" + dataResp.hadError()
               + "\n dataResp.getErrorMessage()=" + dataResp.getErrorMessage());
             
       }

Examples of fetch appData

        private function fetchData():void
       {
               var dr:DataRequest = container.newDataRequest();
               //var idSpec:IdSpec = container.newIdSpec({ com.nextgenapp.opensocial.IdSpec.Field.USER_ID : "VIEWER"});   // does not work.  has compile error.
               //var idSpec:IdSpec = container.newIdSpec({ "USER_ID" : "VIEWER"}); // do this instead.
               var idSpecParam:Object = {};
               idSpecParam[com.nextgenapp.opensocial.IdSpec.Field.USER_ID] = "VIEWER";
               var idSpec:IdSpec = container.newIdSpec(idSpecParam);
       dr.add(dr.newFetchPersonAppDataRequest(idSpec, ["testdatakey1"], null), opt_key);
       dr.send(fetchPersonAppDataCallback);
       }
       private function fetchPersonAppDataCallback(dataResp:DataResponse):void
       {
               trace("fetchPersonAppDataCallback()");
               Alert.show("fetchPersonAppDataCallback()");
               if (dataResp.hadError()) {
                       Alert.show("error: " + dataResp.getErrorMessage());
               }
             
               var appData:Object = dataResp.get(opt_key).getData();
               Alert.show("appData=" + appData);
             
               // appData should have a member (user's id).  inside that, it should have a member
             
               var appDataDisplay:String = "";
               for (var propNameLevel1:String in appData) {
                       appDataDisplay += ("\n" + propNameLevel1 + " : " + appData[propNameLevel1]);
                       for (var propNameLevel2:String in appData[propNameLevel1]) {
                               appDataDisplay += ("\n----" + propNameLevel2 + " : " + appData[propNameLevel1][propNameLevel2]);
                       }
               }
             
               Alert.show("appData expanded=" + appDataDisplay);
       }
