Description

Steps to reproduce:
Create a two-way bind on a RadioButtonGroup and try setting it's selection property to null.

Actual Results:
The first RadioButton in the group will be selected.

Expected Results:
No RadioButton in the group will be selected.

Workaround (if any):
None.

I've done this as an Air app and in a browser. All the same.
Flex SDK: 3.2.0.3958, 3.2.0.4331

Demo MXML file attached.

When a single direction bind is applied, in either direction, clearing of the RadioButtonGroup works like it should.
When no bind is applied, clearing of the RadioButtonGroup works like it should.
The order of establishing the two-way binds makes not difference.

Another strange side effect of the two-way bind is that the first radio button is selected. Of course, nothing should be selected unless specified.
