How to catch exception with Task Switch Gateway component

Hi all,

When I started the task in the task list. I often got the exception:

RequestException: The task with identifier '846' was already finished or does not exist (Session identifier is '45').

But I want to catch this exception and show a friendly dialog to the user.

I am looking forward to hearing any ideas from you

Instead of linking the task directly you could execute dialog logic when a user tries to resume a task. Within this dialog logic you check if the task still has the correct state. (E.g. by using the workflow api: TaskQuery.create()....) If the task state is correct, you redirect to the real task-pickup URL, otherwise you show a nice dialog, that somebodey else finished the task.
