BPEL Human Workflow - dynamic Outcomes

Hello All,
While designing human task, I can pretty much provide XPATH everywhere, but I couldn't provide xpath for outcomes.
Is it possible to provide dymanic outcomes?
- I am not sure how does Worklist App figures out set of outcomes, I didn't it as part of task input.
I appreciate your help.
Thanks,
Chintan

Alright, it is certainly getting interesting to me, and would really appreciate if somebody provide any insight to this issue.
- I saw that TaskLink input (initialTaskInput), does have property called parallelOutcomeCount in systemAttributes, which decides type of outcomes to worklist application.
q.1: Why I am not able to override this attribute (parallelOutcomeCount )? I tried to put my own value right before the INVOKE operation, still it didn't work, it got over-ridden by BPEL engine?
q.2: I don't see any ASSIGN activity to assign parallelOutcomeCount, I do see assign activity for assign system and payload activity generated during Human Workflow. How do they get set? Is there is any interceptor concept?
Really curious, because it there is any hidden way to set such variable, I would love to use such framework for many different purposes.
Thanks!
Chintan

  • Exposing BPEL Human Workflow Activities in ADF

    Hi All,
    I want to have a clear idea on best practices/ ways on
    "How to expose BPEL human workflow processes in ADF".
    Do I need to create an ADF application where I can consume BPEL datacontrol.
    or Do I need to manage ADF datacontrols with BPEL databases and create VO EO and create datacontrol.
    What could be the best practice on exposing BPEL Human workflow in ADF.
    Waiting for reply.
    Regards,
    Hoque

    Hi Hoque,
    you can create direct an ADF Task Form Projekt from your HumanTask Wizard. Cehck out this two links:
    Implementing an Oracle ADF Task Flow for a Human Task - 11g Release 1 (11.1.3)
    http://docs.oracle.com/cd/E28271_01/dev.1111/e10224/bp_tutorialhwf_.htm
    Never access the SOA Suite databases directly, it is a bad practice.

  • Cancel Task in BPEL human workflow

    All,
    We have a requirement to cancel the task for the user using human work flow. The worklist should be deleted for the user. Let me know if oracle human workflow provides an opertaion option to cancel the task like reassign,initaiate etc.
    Regards,
    M.Rajesh

    Ronald,
    By cancel means i need the worklist entry for the given taskid to be deleted or marked as cancel so that the user will not be able to process the task. The BPEL process should have a human task process defined like updatetask which will cancel the task.
    Let me expalin our scenario.
    We have an assignment which has different status like new,reassign,cancel. Using a switch we check for the required status and if the status is new we call the initaiate task. Similarly if the status is cancel we need to cancel or delete the task for the user.

  • BPEL human workflows: How to carry task parameters to another flow

    Hi all
    i want to split the flows to make it maintainable. i have 8 humantasks including flow and when i split this, it will share 3-5 humantasks in each of them. i want to carry the task details from first flow to second one(History,payload and comments). Actually according to customer these 8 humantasks make 1 business task together so they want to see the history of all in one thread(assume that you track only 1 task). So what is the best way to carry task details from one flow to other one?
    Thanks

    Hi,
    Since the human task out is in a global variable by default you can copy the output of previous tasks in the assign of every next human task. I do not know if this also will be posible for the history. This is could be task dependend. If you have trouble copying the output directly to the input in case of e.g. arrays, you could also use a self defined global variable that holds the information needed in between human tasks.
    Kind Regards,

  • Differences in Oracle Service Bus, BPEL and human workflow

    Hi Everyone,
    I am newbie, don't know if its the right place to post this thread.
    I want to prepare paper on differences in Oracle Service Bus, BPEL and human workflow, can anybody help me.
    Till now i came to know all these things are very different, no poit comparing them but still need differences
    Thanks in advance:
    Vikas

    Basic difference:
    BPEL : It is used for orchastrating different processes. Its heavyweight and stores instances (stateful)
    OSB : It is used for routing data between the applications
    Human Workflow : It is used to handle scenarios where manual intervention is necessary.

  • 10.1.2. to 10.1.3 Human workflow task migration issue

    Hi all,
    I am currently looking at the possibility to migrate our 10.1.2 bpel processes, containing human workflow task, to 10.1.3.1.0 Everything seems to migrate smoothly except the human workflow functionality.
    The initateTask invoke action returns the following error in the 10.1.3.1 console when I ran an 10.1.2. bpel process containing a human workflow task:
    [2006/12/04 03:01:00]

    I know that in 10.1.3 the human workflow mechanism is heavily changed and now is invoked by using other services (TaskService) than the services used (TaskActionHandler process)in 10.1.2. In 10.1.2 the TaskActionHandler was a separate build-in bpel process used for interaction between a bpel process and the human workflow. This process is not present in the 10.1.3.1 installation, so that is causing my error. Moreover, in 10.1.3 the interaction between a bpel process is and the human workflow is not done by invoking a separate bpel process (TaskActionHandler) but by invoking a java wsif service TaskService..(Correct me when I'm wrong or not complete)
    My question now is how can I migrate my 10.1.2 human workflow task to 10.1.3.1 without manually rewrite the task scopes to 10.1.3...According to the fragment below copied from the JDeveloper 10.1.3.1 help files it should be possible. Maybe, there's is a way to deploy the needed processes manually?
    Oracle BPEL Process Manager Workflow Services 10.1.2 and 10.1.3.1.0 Compatibility
    For release 10.1.3.1.0, the workflow wizard has been replaced by a Human Task editor. This editor enables you to specify task settings such as task outcome, payload structure, task participants, assignment and routing policy, expiration and escalation policy, notification settings, and so on. You cannot use the Human Task editor to edit 10.1.2-based workflows. To use any new 10.1.3.1.0 functionality, the task scope of the workflow must be manually migrated to use the new workflow metadata. Note also that this is the last release in which you can deploy workflows designed with 10.1.2.
    Kind regards,
    Tom Hofte

    Hi Clemens,
    Thanks for your quick response. The Taskmanager and the Taskactionhandler are indeed not deployed so I will do that automatically.
    Still one question/remark left:
    You noticed that you still have to complete the tasks using the old worklist app. . So if i'm correct, you have to use the deprecated 10.1.2 worklist api or build-in worklist app. The 10.1.2 worklist app is not deployed in my 10.1.3 installation. However, 10.1.3 only contains the new worklist app. Is there also a way to deploy it manually?
    Writing this down it al looks a bit clumsy to me. Is it not a better option to invest some time in migrating all tasks scopes manually to 10.1.3, because as far as I can see the human tasks are causing the main issues concerning migration? After this you have a 10.1.3 compliant system. I wonder what your opinion is on this issue.
    Kind regards,
    Tom

  • More information about additional human workflow task methods needed

    The typical human workflow task only uses the initiate method of the Task service, although there are many methods available. I would like to have my BPEL process reinitiate or renew a task if not completed properly or not approved by a separate task outcome, but am running into difficulties getting it working properly.
    Where can I get more information on how to use the additional methods, or specifically how to re-assign a task that was already completed to the same user to re-complete?

    Here is the error in the BPEL domain log file. To reproduce this, I initially had 2 separate tasks. I then changed the second one to call reinitiateTask instead of initiateTask, and changed all variables and paths appropriately. I changed the second tasks Assign activities to perform a copy operation of the first task results global variable into the reinitiateTask local variable, then copied the URI path to the second task file so it would force it to use the second task metadata, then copied over the title so the task would display appropriately for the manager, and this is what resulted:
