[rules-users] DSL matching return wrong DRL

Hi everebody, I've a quiestion about DSL: I have the next DSL: [when][]Get month = $month: Month(); [when][]Get month summer = $month: Month(id in (6,7,8,9)); [then][]Print months = System.out.println("Month: " + $month.getId()); And the next Rule: rule dsl2drl_1 when Get month summer then Print months; end When the ksession fires we get the error: DSLR: [10,20]: [ERR 101] Line 10:20 no viable alternative at input 'summer' in rule dsl2drl_1 But It works ok if I change the first DSL from : - Get month = $month: Month(); to ('s' is added in 'month' word) : - Get months = $month: Month(); What could be the problem? I use Drools 5.0.0.CR1 and jdk1.5.0_16 I attached a small project for test. Thanks -- Luis Enrique Silva Valdivieso Cel. 00 51 1 991546707 Casa 00 51 1 4476616
