I cant seem to trace out the data field of my list component.

Here is what I have adding to my file list:

```auto
filelist.addItem({label: file.name+" - "+(Math.round((file.size/1024)))+" KB", data: selectedFileArray*});

```

and now I want to trace the datafield so I did

```auto
var uploadWhat = filelist[currentIndex].data;
    trace(uploadWhat);

```

I get this error:

```auto
ReferenceError: Error #1069: Property 0 not found on fl.controls.List and there is no default value.
    at uploaderas3_fla::MainTimeline/startUpload()

```
