[rules-users] Drools Flow: Problem with Human Task

Hi, I'm stuck on this "simple" problem for two days now and I couldn't find the answer anywhere. I have a simple ruleflow (Start -> Human Task -> End) and when I start the process it breaks like this: **************************************************************************** [2010:04:102 15:04:971:exception] Uncaught exception on Server java.lang.NoSuchMethodError: org.drools.util.ChainedProperties.<init>(Ljava/lang/String;)V at org.drools.task.service.SendIcal.<init>(SendIcal.java:73) at org.drools.task.service.SendIcal.getInstance(SendIcal.java:67) at org.drools.task.service.TaskServiceSession.addTask(TaskServiceSession.java:138) at org.drools.task.service.TaskServerHandler.messageReceived(TaskServerHandler.java:88) .... **************************************************************************** I'm using drools 5.1.0M1 and the "drools.email.conf" is in the META-INF directory. Mina server is started without problems. I've ran out of ideas, please help...
