Hi Nicolas and welcome, here's a blog post about data binding that can help you with it:
https://royale.apache.org/binding-the-text-property-of-a-jewel-textinput-to-update-a-text-label/ At the end it links to the Royale Data Binding Docs page too. You can check as well TDJ source code where data binding is used heavily https://royale.apache.org/tourdejewel/ https://github.com/apache/royale-asjs/blob/develop/examples/jewel/TourDeJewel thanks Carlos El dom., 17 may. 2020 a las 8:19, Alex Harui (<[email protected]>) escribió: > Hi Nicolas, > > > > Looks like you are using the Jewel component set, so you may need to add > ContainerDataBinding to the screens.
