[rules-users] GWT Console - Drools Flow problems.

1.)Creating processes in Eclipse. They work. 2.)Exporting them to Guvnor - I can see them, everything is OK. Then I try to start GWT-Console. When I log in, I get this: - URL: 'http://localhost:8080/gwt-console-server/rs/tasks/admin' - Action: 'org.jboss.bpm.console.client.task.LoadTasksAction' - Exception: 'class
