Hi there,

I want to work with declared facts, inside drl file, but when i set
drools.agent.newInstance property to false, it seems that drools won't work with this specific fact.


My code stops working when i put this two lines,

KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.newInstance", "false");

And it works fine when i remove these lines.


So, I've read that this property is related to new instances of KnowledgeBase when resources changes...


c&p from: http://grepcode.com/file/repository.jboss.org/maven2/org.drools/drools-api/5.0.0.M4/org/drools/agent/KnowledgeAgentFactory.java

aconf.setProperty( "drools.agent.newInstance",
                          "true" ); // resource changes results in a new instance of the KnowledgeBase being built,
                                    // this cannot currently be set to false for incremental building


Hence, why is this property changing the behaviour of the rules?
