<span>Hi there,<br><br>I want to work with declared facts, inside drl file, but when i set </span><span><span class="bold highlight search-highlight">drools</span>.agent.newInstance property to false, it seems that drools won&#39;t work with this specific fact.<br>
<br><br>My code stops working when i put this two lines, <br><br></span><span>KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
</span><br><span>aconf.setProperty(&quot;<span class="bold highlight search-highlight">drools</span>.agent.newInstance&quot;, &quot;false&quot;);
</span><br><br><span>And it works fine when i remove these lines.</span><br><br><span><br>So, I&#39;ve read that this property is related to new instances of KnowledgeBase when resources changes...
