Hi,

you should use Exclusive gateway. Behavior is different.
http://www.activiti.org/userguide/#bpmnExclusiveGateway

only one sequence flow is selected when using the exclusive gateway. In case multiple sequence flow have a condition that evaluates to true, the first one defined in the XML (and only that one!) is selected for continuing the process. If no sequence flow can be selected, an exception will be thrown.
