Re: [rules-users] error when referening LHS->exists block var in RHS
That is expected behavior.
This is because quantifier CEs like "exists", "not" and
"forall" will
evaluate multiple facts at once. So, if your rule has 5 foos in the working
memory, which one would you expect to print?
If you want to print each of them, remove the "exists"... if you want to
print all of them, use "collect" instead of "exists".

I get $foo can't be resolved error for following rule. Some guidance is
appreciated to reference $foo without error.
Rule "Foo rule"
when
exists( $foo: Foo())
then
System.out.println($foo);
end
Thanks in advance.
