EnvironmentNotAvailableException when using IWorkflowListener.

Lam Nguyen — Mon, 22 Jan 2018 05:12:12 -0500

Hi All,

We are trying to detect expired tasks by implementing IWorkflowListener. We have same way to detect newly created task, every thing is working fine with create task listener but we are facing environment not available with expired task listener (both listeners are accessing the Ivy environment).

We detects newly created task by checking status WorkflowEventKind.EVENT_CREATE_TASK_BY_JOINED_TASKS and expired task is WorkflowEventKind.EVENT_CHANGE_TASK_TIMEOUT_TIMESTAMP.

My questions are:

What is the different of those states (WorkflowEventKind) when it's fired? Is there any way to access Ivy environment outside request? for example ivy global variable?

Thanks, Lam Nguyen

Ivy TaskState change listener

ToanLC — Tue, 09 Jan 2018 02:39:17 -0500

Hi all,

In our application, we need to detect when task state is changed. For example when user login to Ivy Admin UI and delete a user, tasks belong to that user will change state to UNASSIGNED.

We tried to use IWorkflowListener but it didn’t work .

In Ivy, is there any way to listen to this event?

Thanks a lot.

When does the state of task change from resumed to suspended?

For example, a user is working on a task and closes the windows, when does the state of task change from resumed to suspended?

Different behaviour in TaskState in Task Switch Event (Gateway) and User Task

Genzer Hawker — Tue, 02 Aug 2016 12:45:42 -0400

Hi Ivy Team

According to the published document, the User Task is specified

The User Task element calls a User Dialog in a new Task. Thus, it combines the behavior of a Task Switch Event and a User Dialog.

Given the following process:

If I run StartTaskSwitchEvent, a new task will be created. If I run the task, the MainDialog will be opened. At this point, the TaskState of the ITask is already RESUMED.

However, if I run StartUserTask, a new task will be created. If I run the task, the MainDialog will be opened. The strange thing is, the TaskState is still SUSPENDED. Only if I exit the MainDialog and reach the next step (SecondDialog), its state is updated to RESUMED.

Could you explain this behavior?

P.S: Tested on Axon.ivy Designer 6.2.0.
