Sorry that Jess doesn't do a better job of reporting this error in a
sensible way. The message "Bad index -3 in call to get() on this
vector..." when defining a rule always means you've tried to match a
nonexistent slot; usually it's a typo. The rule testbeans2 above is
trying to match a slot named "link", but there is no such slot in any
of your defclasses: there is, though, one named "links", as I've shown
in Test1Intf above.
