Hello,
the following rule
(defrule Simple-not-test
(Test fact ?class)
(not (and (Simple (OBJECT ?o&:(call ?o IsClass ?class)) (name ?name)
(class ?c))
(bla (OBJECT ?o1))))
=>
...
)
causes an error with Jess 6.08, which seems to me not correct (??):
Simple-not-test: +1+1+1=1+1+1+2+2+t
Exception in thread "main" Jess reported an error in routine
ReteCompiler.eval
while executing (batch itm.clp).
Message: Unbound variable found in funcall: _2_o parsing defrule
Simple-not-test&1 .
Program text: ( batch itm.clp ) at line 1.

Funny is that this problem does not appear, if I change the order of the
two sub-rules in the (and ...) which would be the workaround. But I
don't know yet, whether it really works due to the problem I posted
earlier ...
