I have an existing process definition deployed (jbpm-jpdl-3.2.2.jar). As
expected, there are new requirements for which we need to add to the process
definition. I would like to modify the existing process definition rather than
deploy a second version.
Otherwise, I will need to write a program to convert all of the existing
process instances to the new version.
While our process is complex (lots of nodes, decisions, wait states and sub
processes), I'm hoping modifying the process definition is a doable programming
exercise.
Basically, I want to modify a couple of current wait states to include new
outbound transitions and then new processing paths (nodes/decisions/wait
states).
Sorry for the long lead up to my questions. First, since I am only adding to
the process definition and not modifying (removing/renaming/deleting) anything
that currently exists, will I be safe to just "add" the new stuff to the
process definition table (created using POJOs and hibernate - not directly
inserting into the table)? I was thinking of loading the process definition
and then "adding" nodes (of the correct type) via the api (I'm assuming there
is an api to do this).
Or will I also need to modify all of the existing process instances?
Basically what we are doing is modifying the current flow:
start -> node -> node -> wait --A--> node --> etc...
--B--> node --> etc...
To add a third transition:
--C--> node --> etc...
So any "open" process instance can execute the C transition from the wait state
(if that is where the PI is waiting).
TIA,
Chris....
