----------------------------------------

Jean-Marc,

Both me and Mario tested this and it is working fine for us in master. Test case I used:


    @Test
    public void testExpressionConstraints4() {
        String drl = "package org.drools\n" + 
                     "rule R1\n" + 
                     "        dialect \"mvel\"\n" + 
                     "    when\n" + 
                     "        Mailbox( owneremail == 'bob at mail' || owneremail == 'john at mail' )\n" + 
                     "    then\n" +
                     "end\n" + 
                     "rule R2\n" + 
                     "        dialect \"mvel\"\n" + 
                     "    when\n" + 
                     "        Mailbox( ( owneremail == 'bob at mail' ) || ( owneremail == 'john at mail' ) )\n" + 
                     "    then\n" + 
                     "end\n";
        KnowledgeBase kbase = loadKnowledgeBaseFromString( drl );
        StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

        ksession.insert(new Mailbox("foo at mail"));
        int rules = ksession.fireAllRules();
        Assert.assertEquals( 0, rules );

        ksession.insert(new Mailbox("john at mail"));
        rules = ksession.fireAllRules();
        Assert.assertEquals( 2, rules );
    }

Can you please double check that you got all the proper jars in the classpath?

Thanks

> Such expressions in LHS do not compile anymore :
> C( f == "a" || f == "b"  )
>    
> ==> compiler says :    Predicate ' f == "a" || f == "b" ' must be a Boolean expression
> Note that this does not work any more :
> C( ( f == "a" ) || ( f == "b" ) )
