RE: [flexcoders] Throwing error on doDrag

[Alex Harui]

Is it undefined?  Maybe there's no data in the ADG yet?

Subject: [flexcoders] Throwing error on doDrag

 

I just don't understand what is going on here. I have the following code

var dragChild:UIComponent = UIComponent(event.currentTarget);


var ds:DragSource = new DragSource();

ds.addData(dragChild.parent, 'dragParent');

ds.addData(dragChild, 'dragChild');


var proxy:UIComponent = UIComponent(event.currentTarget);

var bitmapData:BitmapData = new BitmapData(proxy.width, proxy.height);

bitmapData.draw( proxy );

var bitmap:Bitmap = new Bitmap( bitmapData );

var image:Image = new Image();

image.source = bitmap;

// Call the DragManager doDrag() method to start the drag. 

DragManager.doDrag(dragChild, ds, event, image);

The problem throws an error on the last line saying
A term is undefined and has no properties

And then opens up the AdvancedDataGrid.as file and shows me this line.

public function get firstVisibleItem():Object
{

--> return listItems[0][0].data;

}

Why am I getting an error thrown, and why is it being thrown in the
AdvancedDataGrid.as file. I am not doing anything with the
AdvancedDataGrid. Just using Panels, Canvas, Vbox, and UIComponent.

If I comment out all the addData lines there is no error thrown, so it
has
something to do with what I'm putting in the Datasource. I also checked
those variables and they seem ok.

Any ideas?
