Example 1 with BaseTaskListener

use of org.activiti.engine.delegate.BaseTaskListener in project Activiti by Activiti.

the class ListenerNotificationHelper method executeTaskListeners.

public void executeTaskListeners(UserTask userTask, TaskEntity taskEntity, String eventType) {
    for (ActivitiListener activitiListener : userTask.getTaskListeners()) {
        String event = activitiListener.getEvent();
        if (event.equals(eventType) || event.equals(TaskListener.EVENTNAME_ALL_EVENTS)) {
            BaseTaskListener taskListener = createTaskListener(activitiListener);
            if (activitiListener.getOnTransaction() != null) {
                planTransactionDependentTaskListener(taskEntity.getExecution(), (TransactionDependentTaskListener) taskListener, activitiListener);
            } else {
                taskEntity.setEventName(eventType);
                taskEntity.setCurrentActivitiListener(activitiListener);
                try {
                    Context.getProcessEngineConfiguration().getDelegateInterceptor().handleInvocation(new TaskListenerInvocation((TaskListener) taskListener, taskEntity));
