I'm creating an expert system in CLIPS, The user will use the system
interfacing through GUI in Java.
Obviously, I use the library CLIPSJNI.

My expert system involves planning scuba diving (I'm creating for academic
purposes, I love SCUBA, and so...).

To begin with, I have relied on the AutoDemo example (
I have changed some things.

Now, my project is still at the beginning, but already has a bugs. You can
try my project and notice the bug: if I play SmartPlan.java, if I do a
choice and I press NEXT ("Successivo", I'm italian ^^), and after I go back
to some screen (with "Precedente") and change my choice to another... the
system does not display the correct next screen! I believe that the problem
is in scuba.clp.

My project is here: https://github.com/gioce90/SCUBA_Diving_ExpertSystem

Can you help me?
