Hi all,
I’m stuck on this for over two days and cant find an answer.
I’m trying to create a datagrid using an arraycollection as the dataprovider.
The collection holds Guest objects.
The data grid recognizes the data but nothing is showen.
can please someone help, I dont know whats wrong.

thers the code:

<?xml version=“1.0” encoding=“utf-8”?>
<mx:Application xmlns:mx=“http://www.adobe.com/2006/mxml” layout=“absolute” creationComplete=“init()”>
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import Data.Guest;

 [Bindable]
 private var guestsA:ArrayCollection; 
 
 private function init():void
	  {
	   	 guestsA = new ArrayCollection();
	     guestsA.addItem(new Guest("baba",3,"bride","father","family"));
		 guestsA.addItem(new Guest("gala",3,"groom","father","family"));
		 guestsA.addItem(new Guest("shala",3,"groom","mother","friend"));
		 guestsA.addItem(new Guest("fala",3,"groom","father","family"));
		 //guestsA.addItem({title: ADD_TASK});			 
	  }
	  
	   ]]&gt;        
&lt;/mx:Script&gt;

&lt;mx:DataGrid id="myDG" width="100%" height="100%" dataProvider="{this.guestsA}"&gt;
&lt;mx:columns&gt;
	 &lt;mx:DataGridColumn headerText="Name" dataField="name"/&gt;
	 &lt;mx:DataGridColumn headerText="Number of poeple" dataField="numOfPeople"/&gt;
	 &lt;mx:DataGridColumn headerText="Side" dataField="side"/&gt;
	 &lt;mx:DataGridColumn headerText="Inner Side" dataField="innerSide"/&gt;
	 &lt;mx:DataGridColumn headerText="Category" dataField="category"/&gt;
&lt;/mx:columns&gt;
&lt;/mx:DataGrid&gt;

</mx:Application>

and the Guest object:

package Data
{
[RemoteClass]
public class Guest
{
//Class Veriables
private var name:String;
private var numOfPeople:int;
private var side:String;
private var innerSide:String;
private var category:String;
private var tableNum:int;
private var apArrivel:Boolean;

	public function Guest(name:String, numOfPeople:int, side:String, iSide:String, category:String)
	{
		this.SetName(name);
		this.SetNumOfPeople(numOfPeople);
		this.SetSide(side);
		this.SetInnerSide(iSide);
		this.SetCategory(category);
		//this.SetTableNum(tableNum);
		//this.apArrivel = apAr;
	}
	
	public function toString():String
            {
                    return this.name + " " + this.numOfPeople + " " + this.side + " " + this.innerSide
                    + " " + this.category;
            }
