Hi,

I have an expression where I am comparing a Boolean to a String which I would expect to fail but the expression always returns true. Is this expected behaviour?

I modified the Drools HelloWorldExample and changed the status from an int to a boolean.

import org.drools.examples.HelloWorldExample.Message;

rule "Hello World"

when

        m : Message( status == "hello", message : message )

    then

        System.out.println( message );

end

public static class Message {

public static final boolean HELLO   = false;

public static final boolean GOODBYE = true;

private String message;

private Boolean status;

public Message() {}

public String getMessage() { return this.message; }

public void setMessage(final String message) { this.message = message; }

public boolean getStatus() { return this.status; }

public void setStatus(final boolean status) { this.status = status; }

}

final Message message = new Message();

message.setMessage( "Hello World" );

message.setStatus( Message.HELLO );

final StatefulSession session = ruleBase.newStatefulSession();

session.insert( message );

session.fireAllRules();

Thanks very much,

Len
