[flexcoders] Problem with showing dynamic combobox

[timgerr]

Hello all,
I an running into a problem, when I create a Actionscript ComboBox
like this:

[Bindable]
public var respArray: Array = [
{label:""},{label:"Yes"},{label:"No"},{label:"N/A"},{label:"No
Responce"}];

var cb1:ComboBox = new ComboBox();
cb1.id = 'cb1me';
cb1.dataProvider = respArray;
addChild(cb1);

All is displayed correctly

But when I add the labelField like this
var cb1:ComboBox = new ComboBox();
cb1.id = 'cb1me';
cb1.dataProvider = respArray;
cb1.labelField  = 'Please Select';
addChild(cb1);

When this is displayed the ComboBox displays:
[Object Object]
[Object Object]
[Object Object]
[Object Object]


Why is the labelField  messing up my array?

Thanks,
