I can reproduce that error with Foo and Bar, running Jess7.1a1, due to
some null pointer exception in the eval. But the documentation for the
Jess function call says: The functor call may be omitted if the
method being called is non-static. I guess that means that the call,
as tried by Henrique,
Note that I said Bar and then Foo, but of course I meant Foo and then
Bar. If you run these and get an error, let's see it! Nobody's showed
me an actual trace yet.

Here is another check on the effect of bsave/bload. I define this function:
(deffunction ppallfunctions ()
(bind ?sb (new StringBuffer))
(bind ?it ((engine) listFunctions))
(while (?it hasNext)
(bind ?f (?it next))
(bind ?class (call ?f getClass))
(?sb append ?class) (?sb
This is surprising:
(deffunction ppallfunctions ()
(bind ?sb (new StringBuffer))
(bind ?it ((engine) listFunctions))
(while (?it hasNext)
(bind ?f (?it next))

The same problem occurs when running bin/jess, and (most likely) with
any other of the import-ed things. Statics of some classes are
automatically (imports are in jess/scriptlib.clp) defined as
functions, and that's why there are some exceptions to the rule stated
in the documentation on

Thanks for your persistence. It turns out that this issue has already
been reported and fixed for the next release, and that's why I
Userfunctions don't really have a pretty-print representation. In
general, the output of PrettyPrinter is Jess code, and since most
Userfunctions are classes defined in Java, there isn't any way to
sensibly implement visit(Userfunction).
