Hi everybody,<br><br>It is possible to use a final global variable into the LHS part of a rule?<br>Since the final global variable is in fact a global constant I think it will be ok to use it in some predicate expression or into an eval of a rule.<br><br>But I get this ugly exception, when I'm trying to use my global in the LHS part of the rule:<br><br><span style="font-family: courier;">Exception in thread "main" org.drools.RuntimeDroolsException: java.lang.NullPointerException</span><br style="font-family: courier;"><br>I mention that when I use the same global variable in the RHS part of the rule, everything works fine, and I'm getting the appropriate results.<br><br>Best regards,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Oana<br>&nbsp;<br><p>&#32;
