>             Project: Apache Flex
>          Issue Type: Bug
>          Components: mx: ComboBox
>    Affects Versions: Adobe Flex SDK 3.5 (Release)
>         Environment: Affected OS(s): Windows
> Browser: Internet Explorer 7.x
> Language Found: English
>            Reporter: Adobe JIRA
>             Fix For: Apache Flex 4.11.0

> Steps to reproduce:
> 1. Create a mx:ComboBox on a panel and bind a data provider to it
>  ... 
>  [Bindable] public var comboBoxDataArray:ArrayCollection = null;
>  ...
>  <mx:ComboBox labelField="name" dataProvider="{comboBoxDataArray}"  width="130"></mx:ComboBox>
> 2. Create 2 ArrayCollection-s of id, name pairs 
>  ...
>  var peopleArray:ArrayCollection = new ArrayCollection(
> 		                [{id:"1", name:"Bob"},
> 		                 {id:"2", name:"Fred"},
> 		                 {id:"3", name:"Petey"}]);
>  ...
>  ...
>  var animalArray:ArrayCollection = new ArrayCollection(
> 		                [{id:"4", name:"Dog"},
> 		                 {id:"5", name:"Cat"},
> 		                 {id:"6", name:"Bird"},
> 		                 {id:"7", name:"Fish"}]);
>  ...
> 3. First assign one ArrayCollection at runtime and then assign the second ArrayCollection,
also at runtime. You can trigger this with a button and you can swap back and forth if you
want...
>  
>  Actual Results: Using Flex SDK 3.5.0 the content of the dropdown (the list) is not updated
correctly after swapping/assigning between the two array collections. 
>  
>  
>  Expected Results: In Flex SDK 3.2.0 and 3.3.0 it works correctly and the dropdown is
updated.
>  
>  
>  Workaround (if any): Downgrade the SDK to a previous version (have not tried this in
3.4.0)
