Hi Sebastian & all, I have set up a quick start project (see https://github.com/cat1000/FutureProgressBar <https://github.com/cat1000/FutureProgressBar>). Please read the readme.txt file contained in the package <pages> to get an overview over the goals and the open questions.
Basically, I am using a Future-Task to load data from a long-running service and in the meantime would like to display the loading progress via a progressBar. This basically is working. However, after the loading has finished, the panel is not reloaded. Thanks a lot for your help!
