[flex_india:26830] Re: Flex error

[swap]

I am using only java.

The destination name I am using is the same.
This is my mxml code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
preinitialize="viewConcentration.getListElements()" layout="vertical"

                        public var collection:ArrayCollection;


                        public function resultHandler(event:ResultEvent):void
                        {
                                collection=new ArrayCollection();
                                expenseArrayCol=event.result as ArrayCollection;

                                for (var key:String in obj)
                                {
                                                 var data:String = obj[key] ;

                }

                 private function displayField(data:Object, field:String,
index:Number, percentValue:Number):String {
                        var temp:String= (" " + percentValue).substr(0,6);

And this is the java method i am trying to call:

public List getListElements(){
                System.out.println("i am inside getListelements");
                List rows = new ArrayList();
                Map pieValues=new HashMap();
                concentrationMap = (Map<String,EnumConcentration>)
FlexContext.getFlexSession().getAttribute("Concentration_Map");
                if(concentrationMap.size() > 0){
                        EnumConcentration concen;
                        for (Iterator it = 
concentrationMap.keySet().iterator(); it.hasNext
();)
                        {
                                concen = 
(EnumConcentration)concentrationMap.get((String)it.next
());
                                pieValues.put(concen.getEnumName(), new 
Double(concen.getAmtPct
()));
                        }
                }
                rows.add(pieValues);
                return rows;
        }
