Changing dataprovider for buttonbar

[chris_d_k <ck...@christiankiefer.de>]

Hi,

I have a button bur with a lot of elements, defined like this:
var iconObj:Object;

var icon1:SpriteVisualElement = new Icon1();
icon1.width = trousersIcon.height = 50;
iconObj1= {icon: icon1, label: ""};

in one case I want to add more items, in another less ...

When I add 2 of the items to the dataprovider and change to 3 and back to
the 2 it works.


When I add 9 of the items to the dataprovider and change to 9 others I get
an error.
When I add 10 of the items to the dataprovider and change to 9 others I get
an error.

var collection1:ArrayCollection = new ArrayCollection([iconObj1, iconObj2,
iconObj3, ..., iconObj9 ]);
collection2:ArrayCollection = new ArrayCollection([iconObj1, iconObj2,
iconObj3, ..., iconObj9 , iconObj10]);

The error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of
the caller.

How can I fix this?

It sounds like icon or button is being re-used and setting to null removes all of them before adding.

When I do the following before changing the dataprovider, it works:

buttonBar.dataProvider = null;
buttonBar.validateNow();

Am I doing somthing completely wrong or is that as supposed?
