Well, I recently described how to find facts and get fact slots on
this very list: see the archive:
http://www.mail-archive.com/[email protected]/msg00396.html
As far as specifically what you're asking, jess.Context is an
execution context - basically it holds the active variables for a
block of code. It can't be used to refer to the facts that activated a
rule, although that's an interesting idea, and one that I might have
to look at in the future. The only reason you get one in a
Userfunction is so you have access to global variables and the Rete
object itself. Context also keeps track of the names of things that
are executing, so they can be displayed in error messages.
I can't think of any way of doing this without making some mods to
the engine itself.
