I install using the ant install.demo.noeclipse. Everything is ok next: ant start.demo.noeclipse and the whole starts and Everything is ok I run google chrome and I type: localhost:8080/drools-guvnor in default package create new "new BMPN Process". I put on the process: Start -> Activities (Task) -> end The properties tab for: process - simulation -> Base Currency: USD process - simulation -> Base time unit: minutes Task -> Type: None Task -> name: Task1 Task -> simulation -> Cost per time unit: 50 Task -> simulation -> Currency: USD Task -> simulation -> Distribution Type: random Task -> simulation -> Processing time (max): 10 Task -> simulation -> Processing time (min): 8 Task -> simulation -> Staff availabity: 2 Task -> simulation -> Time unit: minutes Task -> simulation -> Working hours: 8 I click the validate process, message: There are not validation error I click Run simulation: Number of instance: 2 iterval: 2 Interval Units: minutes and I click "Run simulation" get the message: Simulation engine did not return results.
