How to get transitions BPM activities with PAPI?

Question

Hi:
I wonder if you can get the transitions of the activities of a process with PAPI. And how do you get?.
Also, if you can get the expiration time of each activity, and process in general, and how to get those times.
I hope you can help me and your prompt response.
Greetings.

Hi Eduardo,
Not sure how you'd get the transitions for an activity using PAPI, but here's how you could get the deadline for a work item instance.
Once you get your instance in the "for" loop below you'd use the PAPI variable "PREDEFINE_DEADLINE". As you know, there is an activity deadline (created by having a Due transition coming out of an activity) and a process deadline (created by setting the predefined variable "deadline" somewhere inside the process). This PAPI logic below uses the instanceInfo's three methods getDeadline(), getProcessDeadline() and getActivityDeadline() to retrieve the instance's deadline, process deadline and activity deadline respectively. Know you know this, but the "deadline" variable stores the time of the either the activity or process deadline that will expire first (e.g. if the due transition coming out of an activity will fire in 5 minutes and the process deadline won't fire for another 30 minutes, the PAPI getDeadline() method returns the activity deadline's time of 5 minutes in the future).
If the activity does not have a Due transition, the getActivityDeadline() method returns a null value. Similarly, if the process's "deadline" predefined variable has not been set, then the getProcessDeadline() method returns a null value. If both the activity and the process deadlines are null, then the getDeadline() method also returns a null.
This PAPI logic assumes that you've already done a search and have a list of instances in your "instances.toArray()":
     for (InstanceInfo ii : instances.toArray()) {
       // this gets the deadlines
       Time dl = (Time) ii.getDeadline(); 
       Time adl = (Time) ii.getActivityDeadline(); 
       Time pdl = (Time) ii.getProcessDeadline();
       System.out.println("deadline: " + dl
                             + "\nactivity deadline: " + adl
                             + "\nprocess deadline: " + pdl);
       // this gets the role where the work item instance
       //    is currently is sitting
       System.out.println("role name: " + ii.getRoleId());
       // this gets the name of the activity where the
       //    work item instance is currently sitting
       System.out.println("activity name: " + ii.getActivityName());
. . .Hope this helps,
Dan
