Hi again Wolfgang:<div><br></div><div>Thank you for your quick answer. getFactHandle is the method I needed.</div><div><br></div><div>Concerning the second question, I'm using Drools 5.1.1 and yes, I imported AlarmFact. Below you can find the relevant lines of the drl file, in which the 'real name' of AlarmFact is MDSVHechoAlarma:</div>

Hello everybody:<div><br></div><div>I have two question related to queries:</div><div><br></div><div>First one, the one in the subject, I have a query which retrieves facts which have to be modified and updated in working memory. I've seen that the StatefulKnowledgeSession.update() method has the fact handle as input. Is it possible to set the fact handle to null? If it isn't, how can I get the fact handle using the fact retrieved with the query?</div>
<div><br></div><div>Second one, related to writing, I though of parameterizing the query using the fact pattern, something like this, </div><div><br></div><div><div>query "alarmExists" (AlarmFact key)</div><div>
$alarm : AlarmFact(key1 == key.key1,</div><div> key2 == key.key2,</div><div> key3 == key.key3</div><div> )</div><div><br></div><div>end</div></div><div><br></div>
<div>
<br></div><div><br></div><div>but the rule compiler doesn't accept this sintax. Is it a requirement that query parameters are basic java types or is there a way to write this query using more complex Object parameters?</div>
<div><br></div><div>Thank you for your time.</div><div><br></div><div>Best Regards,</div><div><br></div><font color="#888888"><div>Manuel Ortiz.</div><div><br></div>
