I'm trying to visualise a binary tree which I wrote. In order to do so, I have been attempting to use Eclipse's GEF (Graphical Editing Framework), and followed steps found here:

However, I keep getting stuck at this page:

Can anyone offer some help here?

    Something strange is wrong here. I can't get this page to behave like this at all, there should always be an error message displayed when next + finish are disabled. – greg-449 Mar 16 '17 at 08:28
  • ;_; really? maybe I installed something strange – umop apisdn Mar 16 '17 at 08:53
  • I know there are some Eclipse dialogs with this kind of bug. Did you try to click on checkbox and radio buttons even if they seem to be already set? – Mathieu Garcia Mar 18 '17 at 22:14
  • @MathieuGarcia yup, I tried those, too (they worked). Had no idea what was going on at all, eventually I uninstalled every single thing I had installed to Eclipse (RCP, plug-in development, GEF etc. etc.) and did my visualisation by another method, so this is not an urgent issue now, but I do hope to still figure out why someday... – umop apisdn Mar 19 '17 at 08:39
