@ron I'm still a little unclear about what you want to see in the OSGI chapter. There are support for tree automatically handled TornadoFX artifacts: Applications, Views and Stylesheets. They are all covered in the guide already. If I understood you correctly you wanted to see an example of how to create one bundle with an application and one bundle that contributes a View to that application, right? I feel like this is covered, so I need some more help to understand what you're after, sorry 🙂
