    Ronald,

    In my tests, it works if you use a simple constraint. The problem only happens with constraints that use semantic code.
    I tracked down the problem and it is in the LogicTransformer that is used when an "or" CE is present.

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

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.
Regards,
Michal
