Hi there,<br>
<br>
I&#39;m experiencing the same problem using Drools 5.1.1<br>
Whats the status on this?<br>
<br>
By the way. It also doesn&#39;t work the other way round with<br>
<br>
   not (exists(X(y != z)))<br>
<br>
which is basically the same as<br>
<br>
   forall($x : X()<br>
          X(this == $x, y == z)<br>
   )<br>
<br>
If this is still a problem, how can I surpass this to get expected results?<br>
Thanks in advance.<br>
<br>
Oliver<br>
