How to change field (due date) on _another_ issue after some event in current issue?

[Vadim Pinchuk]

Hi guyz , In our workflow , 1 user can only have 1 task in time, and we have very intensive flow of new tasks. Every new task must "move" dates to chain of user tasks.

for example. Let Today is 1 September 2013

Bill has 2 serial tasks in plan.

- Task 1
started: 1 Sep 13
est: 2 days
deadline : 3 Sep 13
priority : major

- Task 2
started: 3 Sep 13
est: 4 days
deadline : 7 Sep 13
priority : major

Booom! We have new critical task!

- Task 3

started: asap!!
est: 3 days
deadline : asap!!
priority : critical

We assign in to Bill, and we want to auto change dates of all his current and future tasks to next days.

We want something, after that we would have this result :

Bill have assigned to 3 tasks:

- Task 3
started: 1 Sep 13
est: 3 days
deadline : 4 Sep 13
priority : critical

- Task 1
started: 5 Sep 13 [!!!auto changed!!!]
est: 2 days
deadline : 7 Sep 13 [!!!auto changed!!!]
priority : major

- Task 2
started: 8 Sep 13 [!!!auto changed!!!]
est: 2 days
deadline : 10 Sep 13 [!!!auto changed!!!]
priority : major

You are going to need code to do this. Find or write a listener that listens for any event where the assignee might be changed runs a filter for "assigned to <new assignee>" and makes the appropriate changes

(I said "find", but I very much doubt anyone has written one that will do this. I'd look at the script runner for doing this as well)
