Multiple HTTP Requests in for loop response handling

Question

i am working on stock market portfolio. a user saves his stock name , buy price ,etc .i've added this details in database.but while viewing his portfolio he should even get the current price of d stocks he has added. while retrieving i fetch all data from database set them in a bean and for each stock i make a HTTP Request. in result handler i event set the current price into the bean. Problem is my entire application is displayed with all the CurrentPrice fields with null.
private function selectContacts():void
    trace("select before");
    stmt.sqlConnection = this.isDbConnected(conn);
    stmt.text = "SELECT * FROM stocks_t";
    stmt.addEventListener(SQLErrorEvent.ERROR, sqlError);
    stmt.addEventListener(SQLEvent.RESULT, sqlResult);
    stmt.execute();
    trace("select after");
private function sqlResult(res:SQLEvent):void{
    httpServ = new HTTPService();
    data1 = stmt.getResult().data;
    stockList = new ArrayCollection();   
    for(var d:int=0;d<=data1.length-1;d++)
        myPortfolioBean = new MyProtfolioBean();
        httpServ.url = 'http://quote.yahoo.com/d/quotes.csv?s='+data1[d].stockName+'&f=snl1a';
        httpServ.method = 'GET';
        httpServ.addEventListener(ResultEvent.RESULT,yDataResult);
        httpServ.addEventListener(FaultEvent.FAULT,yDataFault);
        httpServ.showBusyCursor= true;
        httpServ.send();
        myPortfolioBean.stockNameB = data1[d].stockName;
        myPortfolioBean.buyB = data1[d].buy;
        myPortfolioBean.quantityB = data1[d].quantity;
        myPortfolioBean.totalQuantityAmountB = data1[d].totalQuantityAmount;
        myPortfolioBean.profitB = data1[d].profit;
        stockList.addItem(myPortfolioBean);
public function yDataResult(evt:ResultEvent):void
    var s:String = evt.result as String;
    var a:Array = s.split(",");
    //To add to a form or individual fields
    lastTraded =  a[2].toString();
    lastTradedFloat = parseFloat(lastTraded);
    myPortfolioBean.currentB = lastTradedFloat;
    stockList.addItem(myPortfolioBean);
    //stockList.addItem({current:lastTradedFloat});
the yDataResult() is called after the entire datagrid is displayed on screen as a result of which the CurrentPrice in datagrid column in null. Eg: user has added google ,yahoo,apple( CurrentPrice  is null for all three values) after some time three more rows (as a result of call to yDataResult) with CurrentPrice xx.xx displayed. I want merged results.

Answer 1

hello ,
"CurrentPrice" is "lastTradedFloat" sorry for the ambiguity.
and u got my problem but there is an issue ..
all the results are set using "sqlResult" except the "lastTradedFloat" which is set in "ydataResult".
but i confused with HTTP ResultEvent Execution.
first "sqlResult" method is called arrayCollection is populated. then result is displayed on screen.( lastTraded value is null then)
then "ydataResult" executes again manipulating data in arraycollection.
what i want is data in "sqlResult" and "ydataResult" to be set sequentially then callin my display page . such that display is correct.
