Description

Steps to reproduce:
1. Add a ButtonBar Component containing a single Object inside the data provider.

<mx:ButtonBar id="bb" x="22" y="31">
<mx:dataProvider>
<mx:Object toolTip="test"/>
</mx:dataProvider>
</mx:ButtonBar>

Actual Results:

Error: ERROR: The dataProvider of 'bb' must not contain objects of type flash.display.DisplayObject.

Expected Results:

it should say something like 'Unsupported dataprovider type', or if the narrative style of the current error is to be preserved, "The dataPRovider of 'bb' must be either a ViewStack or an Array".

Workaround (if any):
