Hello,

Does anyone know why rule "GoodBye2" below does not compile, but rule "GoodBye1" does compile using Drools 4.0.0? The only difference is the "not". Shouldn't this be valid?

Thanks,
-Chris

package com.sample

import com.sample.DroolsTest.Message;
import com.sample.DroolsTest.Foo;
import java.util.List;

rule "Hello World"
   when
       m : Message( status == Message.HELLO, message : message )
   then
       System.out.println( message );
       m.setMessage( "Goodbye cruel world" );
       m.setStatus( Message.GOODBYE );
       update( m );
end

rule "GoodBye1"
   no-loop true
   when
       m : Message( status == Message.GOODBYE, message : message, $foos: foos )
       Foo(id == 10) from $foos
   then
       System.out.println ( message );
       m.setMessage( message );

end

rule "GoodBye2"
   no-loop true
   when
       m : Message( status == Message.GOODBYE, message : message, $foos: foos )
       not Foo(id == 10) from $foos
   then
       System.out.println( message );
       m.setMessage( message );

end
