Timer Boundary Event and User task assignee

I want to send an email reminder to each user task assignee (multiinstance task) after a given period a time. A Timer Event is bound to the user task and triggers a service task (AlfrescoScriptDelegate) that should send an email to the user task assignee.My problem/question: Task object is not ava

There is no task because you are not executing a task listener - only the ScriptTaskListener class will have the "task" variable set as a global variable in JavaScript. Also, you could not have accessed the assigned user from the task variable anyway, since the task you are executing the JavaScript in isn't a user task (it is a service task) and as such does not have an assignee. You would need to execute a task query via the low-level Activiti RuntimeService to find and access the user task to which your boundary event is attached.

Thanks axel, very clear.

So is there any simple way to send a reminder email to user task assignee after a given period of time ?

If you are asking "so simple I don't have to code anything", then no. Otherwise it is quite easy - implement your JavaScript service delegate, use the root scope object "workflows" (WorkflowManager) to query for active tasks in the current workflow - maybe filter for the previous task ID if you have parallel execution paths - and then use the email action to send the mail. For an easy implementation the Alfresco "workflows" root scope object may suffice - I usually don't use it because it hides quite a bit of information that I usually need, but for a reminder you may not need such internals...

Ok thanks I'll try this way.

Just one thing: could you please explain "maybe filter for the previous task ID if you have parallel execution paths" ?

(I'm not 100% sure how to deal with paths to get previous task...)
