Hi,
Well, i think i didn't explain my problem very well.
The problem wasn't with the repeater, but the repeater parent.
let's say my application is like this
<mx:Panel id="displayScreen">
<mx:Repeater id="rep">
<mx:Button id="toto"/>
<mx:TextInput id="tata"/>
</mx:Repeater>
</mx:Panel>
I have to code a very generic code, which doesn't need to know the
component ids, even if they have some.
I made a method which need to know to component parent that need to be
match with the datas.
let say my method is fillFields(parent:UIComponent, datas:XML). then
i'll use it like this
fillFields(displayScreen, datas).
the method will check the parent childs, and recursively will find all
the component in the dispalyScreen and check in the XML document if
there is a data for the component.
Some guys will tell me to use the databinding, but the datas that i
receive from my httpService isnt well formed, that's why i have to
manually match datas with components.
Now the problem is that when i'll call the fillFields method on the
panel (like in the example), the getChildren method of the panel wont
give the repeater like a child. If i want to know the repeaters in the
panel, i have to use the mx_internal namespaced method childRepeaters.
I managed to change the way i use the repeater, and i created a custom
component which is a box with the repeater inside. This way the
getChildren method will be able to get the box and pass it the datas.
This make me create the repeater in ActionScript, what's a real pain.
I overrided the addchild method and used this one
override public function addChild(child:DisplayObject):DisplayObject {
var descriptorProps:Object = {};
descriptorProps.type = UIComponent(child).descriptor.type;
descriptorProps.id = UIComponent(child).descriptor.id;
descriptorProps.propertiesFactory =
UIComponent(child).descriptor.propertiesFactory;
descriptorProps.events = UIComponent(child).descriptor.events;
descriptorProps.effects = UIComponent(child).descriptor.effects;
descriptorProps.document = UIComponent(child).descriptor.document;
_repeater.childDescriptors.push(new
UIComponentDescriptor(descriptorProps));
return _repeater.addChild(child);
}
And now i have a problem with the initializeRepeater method. all the
component i use are Box-based, and i have this error now

Repeater will automatically build an array of references to the
instances. Access them using myId[n].

Encapsulate the reformatting functionality in that component. Pass
in a reference to the entire currentItem via a public property.
Implement the property as a setter function so you can invoke the
formatting when it changes. Be aware that setters can fire before the
children are created.
