Hi Sebastian, I am using a heuristic for an optimization problem and this takes about 5-10 seconds. So it might be a good idea to use a future task to run this service, which receives the data (list of object) in the end. In the beginning, I would like to initialize the model with an empty list so that the page is displayed fast, and in parallel execute a future task; as soon as the service has some results, exchanging the model against the data returned.
I have looked at the example described here: https://gist.github.com/jonnywray/636875 <https://gist.github.com/jonnywray/636875> The future is called correctly, but how can the component/panel be updated via the onPostSuccess(AjaxRequestTarget target) method? By the way, what is the difference when setting the model via constructor (e.g. new Panel(id, model)) or via setDefaultModel method? With the first, the default model is still null.
