delegate usertasks at users absence

Hi all,I have a question about task delegation. It's more about the way to do it, if ppl are on holidays or get ill. The last topic I found here about that problem was more than 1 year ago, but I think there is no API to handle it comfortable implement yet, isnt it?So what should be the best way to

You could use, for example, a process that allows you to fill in who is replacing you when you're on holiday. and what time you're leaving and what time you'll be back. The process has intermediate timer-events and some service-tasks. The timers fire when the start-date is reached, querying all tasks assigned to user X and "delegating" or setting assignee to user Y. Same for end-time, where the assignee is reset.

The above will cover existing processes. For new processes, you'll have to use a slightly modified "assignment" model (use an expression ${assigneeBean.getAssigneeOrReplacement()} or use an assignmentListener on the task that checks if the chosen employee is currently available. If not, assign it to it's replacement (which is stored in another system/db possibly). By using a BPMNParseHandler, you can add that special "assignment" task-listener to all processes deployed in the engine without having to define the listener in all of your BPMN XML's.

Thanks for your quick and helpful reply. I think its a pretty good solution to define a new process which deals with the whole delgation instead of a task on every process. I neglected that solution somehow…So if a user logs in, he can start that new holidayprocess and everything will be handled for him. And if somebody gets ill its good to have that task listener to check in db if he is available. I will adopt your advices.

Thank you very much.

Hi again,

I came to one problem which I cant explain myself. I added candidateUsers to my Usertask in the bpmn.-file and want to check them in a UserTaskListener-Implementation with delegateTask.getCandidates(). But it is always empty. If I use delegateTask.addCandidateUser("Worker1"); before, it contains that 1 element. It just dont work by defining it in the process definition.

Any suggestions what I'm doing wrong?

[SOLVED]

I was using the Listener with assign event, instead of create.

Greetings,
Tom
