Hi, I have following rule that should never fire, but it does :) package com.sample import com.sample.DroolsTest.*; rule "ruleThatShouldNeverFire" when Message( eval("somethingDifferent".equals(message)) ) # this should never match SomeBeanA( ) or SomeBeanB( ) then System.out.println( drools.getRule().getName() + " fired and shouldn't" ); end stateful ruleSession with following insertions: Message message = new Message(); message.setMessage( "Hello World" ); workingMemory.insert( message ); workingMemory.insert( new SomeBeanA() ); workingMemory.insert( new SomeBeanB() ); It behaves the same way if we use predicates or retun values: #Message( msg : message -> ("somethingDifferent".equals (msg)) ) # this should never match #Message( message == ("somethingDifferent".equals (message)) ) # this should never match It looks like the AlphaNode is missing from the Rete network. Tested with Drools 4.0.3. Java build 1.5.0_11-b03. Any ideas if this is a bug or am I doing something wrong? Thanks.

One question do you get different reslts if you do the folowing for the first rule: Message( message == "somethingDifferent" ) # this should never match All I did was eliminate the eval and the explicit call to equals On Nov 21, 2007 4:05 AM, Michal Bali <michalbali(a)yahoo.ie&gt; wrote: > Hi, > > I have following rule that should never fire, but it does :) > > package com.sample > import com.sample.DroolsTest.* ; > rule "ruleThatShouldNeverFire" > when > Message( eval("somethingDifferent".equals(message)) ) # > this should never match > SomeBeanA( ) or SomeBeanB( ) > then > System.out.println( drools.getRule().getName() + " fired > and shouldn't" ); > end > > stateful ruleSession with following insertions: > Message message = new Message(); > message.setMessage( "Hello World" ); > workingMemory.insert( message ); > workingMemory.insert( new SomeBeanA() ); > workingMemory.insert( new SomeBeanB() ); > > It behaves the same way if we use predicates or retun values: > #Message( msg : message -> ("somethingDifferent".equals > (msg)) ) # this should never match > #Message( message == ("somethingDifferent".equals (message)) > ) # this should never match > > It looks like the AlphaNode is missing from the Rete network. > > Tested with Drools 4.0.3.
