I'm using drools-camel 5.4.0.Final. ksession is stateful, I'm in STREAM mode, and rules are fired with fireUntilHalt(). My test route is: from( "direct:test-message" ).to( "drools://node/ksession1?action=insertMessage" ); I'm sending my objects into the engine like so: template.sendBody( "direct:test-message", new Person( "Bob" ) ); template.sendBody( "direct:test-message", new Person( "Jim" ) ); I have two rules that I'd like to fire in a specific order (1a followed by 1b). If I define rule1a first in my drl it fires first as I would expect (with or without a salience specified). But if I define rule1b first, that fires first even though rule1a has a higher salience. Here are my two rules / test cases and the results: *Scenario 1 (rule1a first first as I want it to):* rule += "rule rule1a salience 100 \n"; rule += " when \n"; rule += " $m : Message( body.class == Person.class, $body : body ) \n"; rule += " $p : Person() from $body \n"; rule += " then \n"; rule += " System.err.println( \"rule1a: Just found person \" + $p.getName() ); \n"; rule += "end\n"; rule += "rule rule1b\n"; rule += " when \n"; rule += " $m : Message() \n"; rule += " then \n"; rule += " System.err.println( \"rule1b: Just found message \" + $m.getBody().toString() ); \n"; rule += "end\n"; *Output:* rule1a: Just found person Bob rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@b49448 rule1a: Just found person Jim rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@f4e9d3 *Scenario 2 (rule1b fires first even through rule1a has a higher salience):* rule += "rule rule1b\n"; rule += " when \n"; rule += " $m : Message() \n"; rule += " then \n"; rule += " System.err.println( \"rule1b: Just found message \" + $m.getBody().toString() ); \n"; rule += "end\n"; rule += "rule rule1a salience 100 \n"; rule += " when \n"; rule += " $m : Message( body.class == Person.class, $body : body ) \n"; rule += " $p : Person() from $body \n"; rule += " then \n"; rule += " System.err.println( \"rule1a: Just found person \" + $p.getName() ); \n"; rule += "end\n"; *Output:* rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@1133fd6 rule1a: Just found person Bob rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@ca425c rule1a: Just found person Jim Something simple I'm sure. Any pointers to get my salience working?

Thanks for the reply Mark! However, in my test situation I'm never sending Person objects, only Message objects. The payload of the message contains the Person object. In my application there will be other types of payload objects though. In my test, Rule1a looks for messages containing persons: > rule += "rule rule1a salience 100 \n"; > rule += " when \n"; > rule += " $m : Message( body.class == Person.class, $body : body ) \n"; > > rule += " $p : Person() from $body \n"; > rule += " then \n"; > rule += " System.err.println( \"rule1a: Just found person \" + > $p.getName() ); \n"; > rule += "end\n"; I tried your suggestion and rule1b never fired because Person never exists in memory (only messages that contain persons). My goal is to have a "catchall" rule that catches all messages that haven't been "caught" by other rules. So every message in evaluates at least one rule to true. I figured rule with constraint "when Message()" with a low salience would do that. Since 1a and 1b both evaluate to true in my test, I figured adjusting the salience would adjust the firing order. Thanks for any insight you can offer!!! - Ladd -- View this message in context: http://drools.46999.n3.nabble.com/Why-does-it-seem-like-salience-is-being...

I appreciate you trying to reproduce this W!! I wonder what's different between my test and yours. With the attached test classes and 5.4.0 I'm getting this output: rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@16274ea rule1a: Just found person Bob rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@186b2ca rule1a: Just found person Jim And every once in a while this output: rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@1dfee20 rule1a: Just found person Bob rule1a: Just found person Jim rule1b: Just found message org.apache.camel.component.bean.pojomessage.Person@14a4067 Thanks for the time guys!! - Ladd http://drools.46999.n3.nabble.com/file/n4018685/SalienceTest.java SalienceTest.java http://drools.46999.n3.nabble.com/file/n4018685/DroolsCamelTestSupport.java DroolsCamelTestSupport.java -- View this message in context: http://drools.46999.n3.nabble.com/Why-does-it-seem-like-salience-is-being...

I just tried the same test using 5.3.0 and got the same results. Rule1b fires first. -- View this message in context: http://drools.46999.n3.nabble.com/Why-does-it-seem-like-salience-is-being...

Many thanks to Edson, Wolfgang, and Mark. Edson, your solution of modifying the drools-camel component to call fireAllRules() after each insert did the trick. My salience values are now being honored. Thanks guys!! - Ladd -- View this message in context: http://drools.46999.n3.nabble.com/Why-does-it-seem-like-salience-is-being...
