Can't fork to Task ------------------ Key: JBPM-2287 URL: https://jira.jboss.org/jira/browse/JBPM-2287 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jBPM 4.0.0.Beta2 Environment: JBPM 4.0 Beta2 with JBoss 5.0 Windows XP Reporter: Oliver Lauer Hi, I can't fork to a or several tasks. I get the following exception: 19:33:30,514 INF | [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd@1075056 org.jbpm.api.JbpmException: unsuppported extension org.jbpm.jpdl.internal.model.JpdlExecution at org.jbpm.pvm.internal.model.ExecutionImpl.getExtension(ExecutionImpl.java:1108) at org.jbpm.jpdl.internal.activity.TaskActivity.execute(TaskActivity.java:48) When I debug the source code I see the last method called is the following which always throw an exception: public <T> T getExtension(Class<T> extensionClass) { if (extensionClass == null) { throw new JbpmException( "extensionClass is null. and this execution doesn't support extensions"); } throw new JbpmException("unsuppported extension " + extensionClass.getName()); }
