Does anyone have an idea regarding following in TornadoFX?
If there are multiple instances of the same Fragment, but with different state and data, is it possible to have different instances of the Controller for each of those Fragments?

Where are you instantiating your controllers now then?

So if I have multiple Fragments and for each I'm getting Controller from the Scope, it will always be the same Controller, which won't work properly as every Fragment must deal with own state and data. So what I'm doing (a bit hacky, but not critical for now) is that for each Fragment I instantiate a new Controller
