Intelligent Discovery Assistant not visible in rapidminer-studio 6

Hi,
I've just downloaded rapidminer studio 6 and installed the Intelligent Discovery Assistant through the MarketPlace. On startup, it does not ask me to download/install flora2 & XSB unlike rapidminer 5.3. I had a previous installation of rapidminer 5.3 so I just gave the path to flora2 & XSB which I used before. When I restart rapidminer, I see this stacktrace below in the console. Same thing happens if I download the latest flora2 & xsb version (0.99.5 from http://flora.sourceforge.net/download.html).

Looks like some serious code bug - trying to inherit from a final class. IDA works for rapidminer 5.3 though. Can anyone help?

Hi,
it looks like that extension makes use of some strange magic and is no longer compatible with RM Studio 6. It was developed as part of the elico research project, so I have some doubts it will be adapted to RM 6..
