Interesting. I wonder if @Greg Dove<mailto:[email protected]> has time to look at this. He’s been through more of these scenarios than I have.

Le dim. 17 mai 2020 à 08:19, Alex Harui <[email protected]<mailto:[email protected]>> a écrit : Hi Nicolas, Looks like you are using the Jewel component set, so you may need to add ContainerDataBinding to the screens. Different MXML files can have different binding implementation for performance reasons and there may not be one specified by default for PAYG reasons. You can do that by adding the ContainerDataBinding bead to the MXML files for screens where you have binding expressions in the same way you added ApplicationDataBinding to the main app, or if Ecran1Class is only used as the top tag in an MXML file, then it should be safe to just add the ContainerDataBinding bead in the Ecran1Class constructor. public function Ecran1Class() { super(); addBead(new ContainerDataBinding()); } } HTH, -Alex From: Nicolas Aguttes <[email protected]<mailto:[email protected]>> Reply-To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Saturday, May 16, 2020 at 10:31 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: Binding question/issue Good morning all. I am new to Apache Royale and I don't know how to make binding work I have my main program which call some screens (ecrans.*) each screen has its applicationScript where I define some constant that I would link to bind to the view, it compiles, but the binding doesn't work and shows undefine value.
