Bonjour, J'ai cet exemple mxml très simple.Modules de chargement flexibles L'événement READY n'est pas déclenché, pourquoi?
flex avec l'aide du Générateur sdk flex 3.4.0 si le module est à distance comme http://edofiles.s3.amazonaws.com/calculator.swf
L'événement READY est jamais tiré, je ne comprends pas pourquoi.
Avez-vous le même comportement?
code original est de http://lowpitch.com/blog/modulemanager-and-imoduleinfo-loading-flex-modules-dynamically/#comment-4396
Des indices?

vous pouvez essayer addEventListener sur null info, voir ce qu'il se passe –
