hello,
i'm new in the jbpm world and trying to understand how it works,
while trying to end a taskinstance by using taskinstance.end();
i keep getting the exception "this token is locked by token"
my method
public void completerTask(long id) {
JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
JbpmContext jbpmontext = jbpmConfiguration.createJbpmContext();
TaskInstance task = jbpmontext.getTaskInstance(id);
task.end();
jbpmontext.close();
}
org.jbpm.JbpmException: this token is locked by token[34]
