<br> That is expected behavior. <br> <br> 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? <br>
<br> If you want to print each of them, remove the "exists"... if you want to print all of them, use "collect" instead of "exists".<br><br> []s<br> Edson<br><br><div class="gmail_quote">

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