Problem in  Human Task Flow

Hi,
I have created a bpel having a human task component.
The human task component input schema is :
<emp>
<empid>
<empid>
<empid>
<empid>
<status
<emp>
The empid is an array.
When i test my bpel it successfully created the human task.
I have created the "Auto Generate Task Flow" from human task component .(Creates a project and deployed with the SOA Application)
But when i click on the human task instance in the worklistapp it does not display the data.
Can anyone please tell me the reason of this kind of behaviour ?
Thanks and Regards,
Sachin Thakkar.

There's probably a problem within your assign activity. Check the domain log as Eric suggested. You can find it @:
$ORACLE_HOME/bpel/domains/<your_domain>/logs/domain.log

  • Human Task Flow conflict on Data Controls generation

    Hi, I have two distinct human tasks in one process. When I use new-> JSF-> ADF task flow from Human task to create the task flow for the second task to the same public-html/web-INF folder as the first one, after the generation, the data control for the first human task flow will disappear from the data control window.
    I am trying to rebuid my old app into a new app. Although I can create two distinct human task flows in my old app, no luck in the new app. Both apps use JDev 11.1.1.5 and on the same machine. Anybody can give me some hints on the issue?
    Thank you

    Juan C,
    I use JDeveloper 11g Release 1.
    May be I didn't explained my question correctly.
    taskdetails1 is creating, and in Data Controls I have objects of my BPM Human Task Payload.
    But in that file "PackageCreation.task" in source I can't find any link to instantly created TaskFlow.xml in my UI project.
    So, I have
    NEW project "PackageCreationUI" with PackageCreation_TaskFlow.xml in it (and TaskDetails1 file too).
    AND Did't Changed PackageCreation.task in BPM Project.
    If I use *"BPM form creation wizard"*, after creating project and TaskFlow in it I see Changes in PackageCreation.task in BPM Project, something like that:
    <taskFlowFileLocation>file:/C:/JDeveloper/mywork/testApp/PackageCreationUI/public_html/WEB-INF/PackageCreation_TaskFlow.xml</taskFlowFileLocation>

  • Participate in the same DB Transaction within Human Task Flow ADF screen.

    Functionality:-
    I have a ADF workflow screen generated from a Human Task flow, and for the business reason I run through the ADF Iterator and get the attribute values and persist within a table using an Application Module.
    I am using the Application Module, and creating as below:-
    String amDef = "model.TestAM";
    String config = "AppModuleLocal";
    TestAM service = (TestAM)Configuration.createRootApplicationModule(amDef,config);
    Now, the issue is when I call the saving mechanism within the above AM client interface, it expects a commit, and this transaction doesnt participate in the same transaction as workflow process, so can anyone let me know how to get hold of the transaction handler and make this persistence to participate within the same one workflow transaction.
    Cheers,
    Saran.

    Hi,
    don't see how the transaction can be shared between the two. Any reason you don't use a DataControl for the ADF BC access and instead use client code creating a root application module?

  • How to know which stage has been completed in Human task flow.

    Hi All,
    I have one human task flow where there is three participants. Participant A, B and C and all are in sequence.
    When User B approves the task, i need to do some business logic. when user B approves the task, it will be assigned to User C. I have defined call back events. There i can use task assigned condition to do my business logic.
    My question is that how i can get to know that Task assigned to user C. Because it is a call back event and will be triggered when it will be assigned to A or B. I have tried to user the function previousOutcomeUpdatedBy to check whether it previous user was B or not. but in my case it is coming as workflowsystem.
    instead of User B it is using workflowsystem
    User:workflowsystem; State:OUTCOME_UPDATED; Outcome:CONFIRM
    I am not aware, why workflow system is coming in picture.
    do any one idea, how to solve this use case.
    Regards,
    Sunil

    You can get the status from back end tables.
    Check in SOA INFRA tables. Below is the list of human work flow tables.

  • Dynamic participant block in Human task flow

    Hi All,
    I am working on human task flow and got stopped on below use case.
    I have two participant block let say A and B. I want to assign participant A depends on flat inside task flow parameter. If Flag is Yes, then it should assign to A and on approval of A it should complete the task flow. But if Flag is NO, then it should first assign to B, on approval from B, it should again assign to A and after that it should complete the task flow.
    I tried to use dynamic role assignment but there i am not able to define above use case. Dynamic rule is saying you can assign A or B depends on some rule(task flow parameter) but my requirement is little different.
    If Flag is Yes,
    - assign to A -> on approval -> complete the task flow.
    If Flag is No
    - Assign to B -> on approval from B -> assign to A -> on approval from A -> complete the task flow.
    I want to build this logic inside single human task flow.
    Please help.
    -Sunil

    Hi Zaloa,
    Can you pls try this.This should work.
    1. Go to Edit Task Definition page and add a Parameter of type string(default).
    2. Now come to the human task dialog( the one you get on double clicking the human task activity) and add a value to the parametr you just added(string)using the search light .This value should be the variable containing the value of the asssigne which you want to add dynamically.
    3.Now again go to the Edit Task Definition page and select the Assignment policy and select the expression path builder.
    4. You should be able to see the parameter you just added under task:payload. select this . now your assigne is dynamically added.
    Pls let me know if you need further details. Hope this helps.
    Thnks

  • Human task flow call back events with external web service

    Hi All,
    I have a requirement to call webservice inside human task flow. I have three participant in my human task flow. Let suppose A, B and C. When A approves then task will be assigned to B and when B approves it will go for C.
    My requirement is that, when A approves , then i need to call one external webservice to update database. For this i have enabled call back events from human task flow.
    In this way i got while loop inside my BPEL. In onTaskAssigned operation i am now trying to call external web service. My requriment is to call external service and get data from service. After getting response from the webservice, i want to assign it to next participant.
    But in this case, when user B approves, it goes to onTaskAssigned block and i am able to make external web service also but mean time, it has been assigned to User C which i do not want.
    I want Human task flow to wait for the web service response then only assign it to next participant.
    Please help.
    Regards,
    Sunil

    Hi Sunil
    Have you tried using WebServices Adapter. The usecase seems pretty straight forward. You have a WebService that has some code and some Operations to update some Database. First thing, I hope you have methods/Operations defined with request and response xsd for each operation.
    Now you define the main master payload, that should have all elements specific to your process and also few elements to store the output coming from each operation. Because response of each operation may need to go to other Task and get saved in the Payload also.
    You have like 3 Tasks. To complicate, I will assume that each Task can either Approve or Reject. And last 2 Tasks gets data from payload, previous task and also output from the WebService Operation (method).
    Task A -> Xor Gateway (Approve/Reject) -> If Approve -> Call WebServices Adapter -> Task B -> Xor Gateway(...) -> ......
    At each intersection, you can map the attributes for incoming and outgoing. Based on WebServices output also, you can have Another XOR Gateway and decide to send to Task B or do something else. So combinations of outputs of each service (task or webservice adapter) and XOR gateways, you can have a decent control on the overall flow.
    Note: I am hoping the webservices is Synchronous where you get the response immediately.
    Let me know if I am missing something.
    Thanks

  • Problem in Human Task in BPEL

    I have a BPEL process with eight human task.Ater the last human task in the switch block i have added one assign activity and one mail activity in the "APPROVED" case. I have deployed the process and ran it. The flow got stuck in the last human task receive call back step and not proceeding to next switch, but i have already approved the task from worklist.
    I have added oned one BAM sensor in that receive step and the sensor was set on "completion". BAM has received the data that ""receive completed".so it seems like that the receive actiivity gets completed but not showing in the BPEL visual flow also not proceeding further.
    After that I removed the assign activity and mail activity and tested it once..it worked fine..
    It looks strange to me....

    This is a problem with switch inside a switch.
    When I replaced the switch in the human task with other activities, it works fine.
    It throws a problem just having a process starting with a switch and a workflow within one part of the switch

  • Warning after creating Human Task Flow in ADF project

    I'm using JDev 11g and have created my SOA Composite containing a Human Task.

  • Complete Task with Payload Problem  -- no Human Task Drop Handler

    I'm reading section 26.4.1 of Developer’s Guide for Oracle SOA Suite 11g Release 1 (11.1.1) E10224-01 where it refers to figure 26-5 Human Task Drop Handler for Creating the Task Display Form of section 26.4 Creating a Task Display Form.
    I've generated taskDetails1.jspx. I highlight Task as in the figure and right click in askDetails1.jspx (design tab) but I don't get a Create JSF page dialog as in the figure.
    I get a dialog with Insert Before Show Detail Spacer ... etc (no Create /Human Task/Complete Task with payload etc)
    Do I need to position within a particular element ? or is this a bug ? wrongly documented?

    Hi Diana, thanks for your reply.
    You're probably right about 2 different error messages.
    To the 1st one: I'm sure that status task is Assigned (to me). I received an email and I also reply on that email.
    To error log: I found out that error log appears when I enable email endpoint on Complete Task service. But I managed to solve this problem. I set wrong user. Now I have here the same user as is written in login-config.xml so log seems to be ok.
    So I created new task and tried to complete it via email. Now I receive email with another error:
    LiveCycle ES has tried to process your request and encountered the following error:
    com.adobe.idp.dsc.provider.service.email.impl.EmailProviderException: Error getting user context
    This response to your original email
    Subject:RE:Task Assignment - Process: WorkFlowClient/Test. Task 92 has been assigned to you.

    Body:Complete

    Attachments:
    And to the last point: email endpoint is set up with TestPOP3@mydomain and user receiving email has jpetrla@mydomain. I use Lotus Notes as email client, I tried another account with gmail, but the result was same.
    Now I really don't know to do...

  • Problem with Human Task(hw_services)

    Hi,
    We are facing a problem using the Human Task in a BPEL process.
    When we add a human task and for any BPEL process in Jdeveloper and tried to add a new user to it no Realm is getting selected.
    And when we try to lookup for users getting an error message
    ' Identity Service Client Error
    BPMIdentityService has client error
    Contact oracle support if error is not fixable'
    We're using the default settings for security on dev server.
    Our SOA suite configured on HP-UX machine and using Oracle XE DB which is on Windows XP machine.
    This is working fine with other configurations working on Windows machines.
    And other interesting thing we found is,When we open the em console we didn't find any webservices unders 'hw_services'
    ( IdentityConfigServicePort,IdentityServicePort IdentityService, TaskMetadataServicePort TaskMetadataService,TaskQueryServicePort TaskQueryService,TaskServicePort are not there)
    seems our hw_services are not configured properly. Everything else is working fine.
    Please help advice as it is very urgent...
    Thanks in advance...
    -Sri

    Hi Marc,
    Thank you very much for the reply.
    WorkList Application's URL mentioned in the wf_config.xml is working fine and we are getting the login page.
    But the SOAP endpoints mentioned in wf_client_config.xml for other webservices like Identity Services are not working. Getting HTTP 404 Not Found error message
    We didn't face any other problems with the config.
    Please help advice whether any other details are needed to solve this issue....
    Thanks again...

    Please Help me out..!!!
    Thanks in Advance

    Its due to JDeveloper installation or cache issue...
    I uninstalled completely and installed again. I am able to create Human Task now. Maybe it helps someone.

  • Oracle JDev 11.1.1.5 Human task flow form generation

    Hi all,
    JDev crashes when I try to "createForm" from a human task element.
    I get .... java.lang.NoClassDefFoundError: oracle/adf/library/rc/dependencies/NameResolver
    Is this class contained in the ojdbc jar? if so, why do I need it?
    Any thoughts?

  • Human task flow validation

    Hi,
    how can I do validation before user can do an action on my task. for example when user click on "accept" i want that do a validation to see whether the payload is set correctly or not.
    Thanks

    I figured out the solution. Drop selectonechoice to the page and click finish. Right-click on the component and select bind to an ADF control. From there you set the attribute to be bound and the drop down source from a data source.

  • Problem reentering task flow in dynamic region

    Hi All,
    I have problem with reentering task flow in dynamic region.
    JDeveloper/ADF 11.1.2.3.0
    Use Case:
    Application contains bussines modules(implemented as bounded task flows) displayed in dynamic region.
    In some modules, default activity is Method Call activity which performs some validations(input parameters, state of records in db, etc.)
    and if some conditions are not satisfied, shows message to the user and exits module (navigates to Task Flow Return activity).
    Problem:
    If user tries to start the same module again, nothing happens(message is not shown).
    If user choose some other module and after that start first module, message is shown(so I suppose this means that task flow was correctly exited first time but dynamic region state was not refreshed).
    Current implementation info:
    Dynamic region has attached regionNavigationListener which resets taskFlowId variable in dynamic region bean if regionNavigationEvent.getNewViewId() == null but this listener is not called if Method Call activity directly navigates to Task Flow Return activity.
    (if user navigates to Task Flow Return activity from button on some page, this works as expected)
    Also, I tried to reset taskFlowId variable from task flow finalizer and to programatically refresh region binding, but this still doesn't work.
    So, am I missing some point about refreshing dynamic region or this is bug in ADF?
    Thanks,
    Dario

    I don't have any popup.
    There is only page which contains dynamic region.
    This dynamic region can be empty or can contain one of business modules(bounded task flows) which are invoked from menu.
    In some cases business module must exit(by invoking task flow return activity) immediately after invocation(because some business validations fail).
    In this case, module will show message to the user.
    Problem is that if user call the same module again, nothing happens(message is not shown) because regionNavigationListener(which only purpose is to reset taskFlowId variable when business module exits) is not triggered when Method Call activity(which is default activity in BTF) navigates to Task Flow Return activity.
    Also, I tried to use Router activity instead Method Call, but problem still exists(regionNavigationListener is not triggered).
    Obviously, regionNavigationListener is called only if navigating from page(or fragment) and this is probably a bug in ADF so I opened SR.
