Activity and process finish with custom assignment manager

[DS-22]

Hello,

I have a problem with automatic modes. I have added my own assignment manager
(actually just getAssignments part for I don't quite understand how to use
UserGroupManager, which is unfortunte because it could have been extremely
helpful). Once I added it, Shark started behaving differently - none of
activities that have automatic start and finish modes are actually completed
automatically. I was under implression that regardless the assignment manager,
it should work as set however there is something that I don't see. I can't find
much in the docs either.

As a matter of fact, I have tried examples with runTS.bat on my Windows
machine. If I don't have my assignment manager set, everything works as
expected - activities are created and finished by the engine. However if I
uncomment the line in the config and use
XPDLStraightParticipantMappingAssignmentManager, no more automatic finishes -
the example stops after the first activity is created.

Could someone please explain what is going?

DS

Hi,

I assume these are not automatic activities which are not being executed
but the manual ones, otherwise we have a big problem :-).
If you are executing runTS to test your new AssignmentManager, be aware
that it creates and executes a processes for user "admin".
In the case of Standard or XPDLStraight assignment manager, when you
create processes as admin user and when there are no participant
mappings when Standard assignment manager is used, all the assignments
will go to this "admin" user, and thus at the end of the test all the
processes will be finished.
If your assignment manager generates assignments for a user(s) different
than "admin" (at least for the manual activities at a beginning of the
process), the processes will never get finished since admin will not get
any assignments in his worklist.

Greetings,
Sasa.

Hi, thanks for the quick response.

Yes, that makes sense. One thing is that I am still logged in as admin so I'd
think I should be acting on behalf of any user, which seems not to be the case.
Appart from ability to create process instances, if even that, what can admin
do that a regular user doesn't?

And another only a user may accept and complete an action whereas I'd really
love to have an ability to be able to accomplish the same thing being a part of
user group that activity performer is assiciated with.

Thank you,

DS

Hi,

actually, being user with username "admin" doesn't mean anything for
runTS (ManualTest example). It means for Swing client application
depending on configuration...when you specify the admin group, all the
users belonging to this group are able to see other users' worklists.
Even in that case, it is not recommended that user admin acts on a
behalf of another user in a sense to accept their workitems...
Anyway, being admin means nothing to the core engine but it can mean
something to the applications built on top of the engine.

runTS(ManualTest) logic is to instantiate processes and get the worklist
of user admin...so it will not see or execute workitems from other
users' worklists.

The implementation of the logic to be able to accept/complete activities
of the user if you belong to the same group is also out of the scope of
the core engine.
In some implementations we assign the activities to the groups. From the
core engines' point of view, a group is just another user/resource in
the system (and thus there is a worklist maintained by the shark for
this group resource). From the applications' point of view, when real
user logs in, the worklist for the user is retrieved by querying shark
for the worklists of all the groups this user belongs to, plus for the
worklist of himself.
When user accepts an activity, application calls shark's API to reassign
activity from the group to this user, when it rejects we reassign from
this user to the group...

Sasa.
