Hi there guys.
I'm designing a system in which I intend to use JBPM 3.2.10 as the
process execution engine. This system should act as a platform
over which developers will install processes developed as clients
demands, but this system will also provide means for the end users
to access a task list and execute tasks that are given to them.
I've been able to design almost everything of that platform but
I'm having serious problems to design the whole user authorization
module. For you to understand the problem I must explain 2 things:
an important feature of this platform (responsibility delegation)
and how I need task assignment to work.
Responsibility delegation is a feature with which an user 'A' will
be able to allow another user 'B' to execute tasks initially
assignable to user 'A'. This delegation may be programmed to start
on a particular day and may or may have an expiration date. So,
user A may go on vacations while user B is responsible to do user
A's tasks while he's out. It's not allowed to user B delegate
tasks to user C while also handling user A tasks.
The task assignment scheme is based on roles and groups in such a
way that tasks should only be assigned to users that have a
certain role inside a group he works on. It is possible that many
users have the same role in a certain process but this task should
only be executed once. This is important to work this way because
that's how my company models processes: assigning them to roles
and then people to roles. Also, this model helps a lot to
implement the responsibility delegation feature, since I only have
to 'lend' to user B his delegator's roles and groups.
The problem is I'm not being able to understand how I can use
JBPM's data model to apply those concepts, at least not with the
material I found in the web. Of course, the delegation feature I
must design it myself and I see no problem with that (it's done
already). But while the jbpm identity model works great to me,
after studying JBPM's concepts such as Swimlanes, Pooled actors
and Task Instances, I couldn't understand how I'll relate an user
with the tasks he should be able to execute, considering that each
task's roles. Can someone shed some light on JBPM's models or
provide references that would help me design this feature?
Abraços,
Ramiro Pereira de Magalhães
