Hello, Since it's not the same problem as the old one, i post a new topic on this, i hope this way to do enter in the ToS.
I created a component Box-Based, which contains a repeater and some other attributes. Since my english isn't perfect i'll post part of the code i produced and tell you what's the problem now. public function Prep() { super(); _repeater = new Repeater(); _repeater.dataProvider = _dataProvider; super.addChild(_repeater); } override protected function createChildren():void { this.creationPolicy = ContainerCreationPolicy.NONE; super.createChildren(); _repeater.childDescriptors = this.childDescriptors; } private function fillInternalFields():void { if(_dataProvider != null) { _repeater.dataProvider = _dataProvider; _repeater.initializeRepeater(this.parent as IContainer,true); } } the fillInternalFields() is a method called when i set the datas of the component. i get an error in the createReferenceOnDocument method as it's set here TypeError: Error #1034: Echec de la contrainte de type : conversion de [EMAIL PROTECTED] en mx.controls.Button impossible. at mx.core::UIComponent/createReferenceOnParentDocument()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\UIComponent.as:8199] at mx.core::Container/createComponentFromDescriptor()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\Container.as:3648] at mx.core::Repeater/createComponentFromDescriptor()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\Repeater.as:734] at mx.core::Repeater/createComponentsFromDescriptors()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\Repeater.as:786] at mx.core::Repeater/initializeRepeater()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\core\Repeater.as:529] at com.probtp.fwg.components::Prep/fillInternalFields()[C:\Code\CC_Views\PB19664_IG_ClientLeger-project_Dev1_View1\vob0003-vob\IG_ClientLeger-project-component\IG_Core\src\com\probtp\fwg\components\Prep.as:72] where the line 8199 is r = parentDocument[id] = []; In the debug mode, r = null, parentDocument[id] = null . Any suggestions on what to do here will be welcome please.
