Can somebody explain how to use the Deadline Activity property? I have the case that I will need to instantiate a process and set a variable, let say start_date, to the date that this process was instantiated. After that in one of its activities, say Activity1 I want to make a deadline such that if (start_date+2days) have passed it will move to the next activity if not triggered manually? Is this possible to be done and if so how?
A:
Set the deadline to Synchronous and enter as condition something like:
var d = new java.util.Date(start_date.getTime() + WAIT_TIME_OUT);
d;
where start_date is of type Date and WAIT_TIME_OUT is in milliseconds. WAIT_TIME_OUT can be a process- or package-level WRD with initial value (some kind of constant), or just a numeric value - it is your choice.
Fill in the Exception name with some meaningfull string, for example
TimeToContinueException
Then set two outgoing transitions:
- By exception ("TimeToContinueException");
- By condition - the normal activity completion.
If you need exactly the process start date, you can use the Shark supplied value PROCESS_STARTED_TIME instead your own variable start_date.
