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()); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
