[Edson Tirelli (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBRULES-1519?page=comments#action_12403795 ] 
            
Edson Tirelli commented on JBRULES-1519:
----------------------------------------

To reproduce, I used the following rule:

rule "test alpha composite constraints"
when
    Person( eval( age == 25 ) || ( eval( name.equals( "bob" ) ) && eval( age == 30 ) ) )
then
    results.add( "OK" );
end
