Error while calling DYnamic shell task flow from unbounded login activity

Hi All,
MY problem-Hi ,
In my case I have alogin page in undounded task flow which calls dounded task flow.
My bounded task flow uses dynamic tab shell.And if login is successfull user will be directed to welcome page where default welcome tab shell is open.
When i run my application i m receving tabConetxt null pointer excetion.
As per my knowledeg i know how to pass tab context reference from 1 task flow to other.But not sure how should i pass tab context from Login View activity to welcom taskflow
follwing exception occurs when i click on login link

  • Calling a bounded task flow from  an unbounded task flow

    How can I navigate from an unbounded task flow to a bounded task flow....
    My situation is as follows:
    In the adfc-config.xml, I have a view activity ADMhome, Wildcard as well as a task-flow-call, admTaskFlow.  A control flow goes from the wildcard to ADMhome while another control flow goes from the wildcard to task-flow-call.
    I have a bounded task-flow "adm-task-flow" with two view actitivies: AdmListView and AdmPageView with AdmListView as the default activity. A Control flow goes from the AdmListView to AdmPageView, all pointing the page fragments
    I created another page ADMregion which is a  (jsf) where I dragged the adm-task-flow onto.
    When I ran the application, the home page displayed properly but when I clicked on a command button to invoke the "adm-task-flow", the application will not responded.
    When I looked at the log message, It gave this message:
    <TaskFlowCallXmlImpl> <parse> ADFc: /WEB-INF/adfc-config.xml:
    <TaskFlowCallXmlImpl> <parse> ADFc: Failed to parse element 'task-flow-reference'.
    <ActivityXmlImpl> <parse> ADFc: /WEB-INF/adfc-config.xml:
    <ActivityXmlImpl> <parse> ADFc: Activity metadata could not be parsed. [Activity Type, ID] = ['task-flow-call', ' admTaskFlow '].

    Thanks for this clarifications...
    I created a view activity in the adfc-config-xml and called the page (ADMregion) where the task flow was embedded. It worked well..
    Another clarification I want is this, when do I use a task flow call to call a task flow?  My thinking and my understanding was that when you create a task flow, you use a task flow call to invoke the task flow.
    Pls another aspect I want you to guide me is on calling a java class from jsf and jsff pages. Being new in these technologies, I have having some difficulties navigating and putting all of them together. My problem is this:
    I created a java class under the view package of Application Sources in the View Controller of my Application. The java class returns a value. I designed a jsff form with input fields and and command buttons. I want when I clicked on a command button to take a parameter from the input field and pass it to the java class, the after processing, the java class returns a value which I will place inside one of the input fields in my jsff form.

  • Error while deploying the ADF task flow project based on a SOA human task

    Hi,
    I created a SOA project with a BPEL process containing Human task, deployed it and could able to test it successfully. I created ADF task flow project based on the Human task created in the earlier project and tried to deploy it. It is giving the following error. The idea is to display the task details in BPM worklist.

    Apart from these, I have Model and View Controller projects in the application. If I create the ADF task flow based on a Human task in another sample application, it works fine. Only in this application, it does not work. Not sure what this error is. Any ideas?
    Thanks,
    Manoj

    What I suggest is go into EM and undeploy this composite and all versions. (Only if you don't want the existing ones). Then redeploy your process. This will avoid the version conflict and create a new version. 1.0. Then the next time you try and deploy you need to either specify a new version or check the box to say the version can be over written.
    cheers

  • Error while runtime customization for task flows in jdev drop6 build 11

    Hi,
    I am using jdev drop 6 build 11. I am trying to build a webcenter application in which I want to drag and drop task flows at runtime. I am able to add the ADF components at runtime. I am also able to expose the task flow at runtime on the UI after creating my own catalog. But if I try to add the task flow by dragging it, it gives an unhandled exception and it shows that no metadata found for metadata object for the task flow. And after this error I am not able to add the ADF components as well. It gives the same error. This is the error I get:

    I am using Jdev 11g Release 1 and need help with the following issue...
    Here's an outline of my application..:
    1. There is a main .jspx page with icons to choose different paths.
    2. Each icon denotes a bounded task flow with TRAIN.
    3. Upon clicking on any icon, you get into a series of TRAIN STOPS.
    4. On one of the TRAIN STOP there is a button to ADD NEW which shows a popup that is tied to another bounded task flow with TRAIN STOPS.
    5. This taskflow 2 calls a method as its default activity.
    The issue is when I click on ADD NEW, the popup displays empty. I even put break points on the method and it doesn't even go to the method. The input parameters on the method have been checked so I know that is not an issue. Any clues as to why it won't open the popup..?
    Any help will be greatly appreciated.

    i guess there is something corrupted in the definition file that is created for the method action in your taskflow.. can u cross check that..What do you mean? How do I cross check this...? Please help
    and also check if the DataBindings.cpx has the correct reference of the method definiiton file..Did this..all references point correctly
    or otherwise can u drag and drop the method again on to the taskflow and try.. if this time it had created all entries correctly.?Tried it ...doesn't work =(

  • Passing Parameters to Bounded Task Flow from JSPX

    Hi All,
    1. Created a JSPX page using UIShell template.  This page contains 4 UI Components (InputComboBoxListOfValues) in SingleObjectContextArea.  Created a Managed Bean for this page and capture the selected value in ValueChangeListner and added the value to pageFlowScope.
    2. Created Unbounded Task Flow, dragged the JSPX page.
    3. Have a existing Bounded Task Flow with page fragments, it has MethodCall activity which is expecting inputParameter values from JSPX.
    4. To call the Bounded Task Flow from Unbounded Task Flow (has JSPX page) created 2nd JSPX page using UIShell template.
    5. Dragged the existing Bounded Task Flow into 2nd JSPX page, in context menu selected Region.  This Region is created in SingleObjectContextArea of UIShell.
    6. When dragged its asking about inputParameter mapping of Bound Task Flow.
    7. Configured the inputParameter value which are coming from pageFlowScope.
    8. Dragged the controlFlow from 1st JSPX to 2nd JSPX page to complete the Navigation.
    9. When running the Unbounded Task Flow, it showing 1st JSPX with LOV.
    10. Selected the values and clicked on Submit Action.
    11. Its now showing 2nd JSPX which contains Bounded Task Flow.
    12. But its displaying empty records table.  (Note: I am passing parameters to MethodCall inputParameters as pageFlowScope, My DB has displaying records based on inputParameters when tested it from OrcleSQLDeveloper)
    Could any body help me on this issue.
    My Code Snippets of Data Binding of 2nd JSPX page which has Bound Task Flow as a regionModel.:
    <taskFlow id="TaskFlow1"
                  taskFlowId="/WEB-INF/oracle/apps/TaskFlow1.xml#TaskFlow1"
                  activation="deferred"
                  xmlns="http://xmlns.oracle.com/adf/controller/binding">
          <parameters>
            <parameter id="PartnerKeyType" value="#{pageFlowScope.PartnerKeyType}"/>
            <parameter id="PartnerKey1" value="#{pageFlowScope.PartnerKey1}"/>
            <parameter id="InteractionPartnerRole"
                       value="#{pageFlowScope.InteractionPartnerRole}"/>
            <parameter id="BusinessProcessName"
                       value="#{pageFlowScope.BusinessProcessName}"/>
          </parameters>

    Hi
    first of all Can you get the pageFlow scope variable in taskflow?which you are passing from jspx page?
    if you are able to get the Lov value in Taskflow try refresh taskflow on changing the LOV.
    you need to add input parameter type as boolean,change the parameter from false to true when the LOV value changed.
    now use refreshifNeeded property in pagedef bindings file

  • Calling a bounded task flow (that uses fragments) from another application

    Hello,
    I'm currently having difficulties calling a task flow located inside another application.
    I have application Console which is my main application in which I would like to run other applications within. Inside this Console I have it divided into splitter windows and inside them I have regions. My goal is to be able to call a task flow from another application inside one of these regions but so far I'm having no luck.
    My first problem occurred when I created a 'local' task flow to make a call to another application's task flow. When I set the properties to the task flow call, it gave me an error that it could not find the .XML file for that task flow when I ran the Console application. I then proceeded to copy that .XML from the remote application into the Console's WEB-INF directory and I seemed to get a bit farther. The error I get now is saying that I cannot run a task-flow that uses fragments. It's essentially trying to run that task flow as an entirely new page instead of inside the region that it's bound to. It's NOT a dynamic region (although that's the end goal here). So I then changed the other application's task flow to simply display an entire page rather than fragments inside a region and voila, it works..... kind of.
    To recap how I was able to call another application's task flow inside the Console:
    - I had to manually copy the task flow xml file into the Console WEB-INF directory
    - I had to change the task flow so that it didn't use fragments
    - I have called the task flow but I lose my console page entirely, no more regions or splitters so I'm back to square one.
    If anybody has any suggestions, hints, tips or anything, send them this way and I will be forever greateful.
    Thanks,
    Mark

    Thanks for your response Frank.
    Unfortunately the problem seems to be greater than that. I've been able to package task-flows into a jar library and tried importing them that way with no luck.
    I'm simple trying to call an external task-flow to run inside a region which is inside a splitter panel that I call my console.
    Any other ideas ?

    Sir,
    Can we call a task-flow from a bean in adf?
    Regards

    you can do this using taskflow call activity
    check - Oracle ADF World: ADF Task Flow Call Activities
    http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_activities.htm#ADFFD21945
    you can pass input parameter map and dynamic taskflow reference from managed bean
    check -https://blogs.oracle.com/DavidGiammona/entry/dynamically_assign_task_flow_c
    Or if you want to use dynamic region to swich between taskflows

    Thanks in advance....

    hi
    sorry to say this
    i have not much time to play 20-20 chat. please elaborate you usecase. you can get you answer within a post
    but we will use router when we have some condition.if you are using router. you should use some "condition" what is that?
    but in both the child tab,i just have to fill the form.ok. i hope that you are using af:table in parent TF. in child tab you are using af:form
    before commiting or at the time if commiting you should get the data's in af:form. if am right means you should have association/viewlink between those eo's/vo's
    if you have means while commiting the parent table iterate over the rows show in child tab - af:form
    it will show the both the child panel.go to panettab render poerpty rendered say as condition {yourparenttableiteratoecount ge 0 ? true : false}
    or else as you said, make router condition {yourparenttableiteratoecount ge 0} show the child TF.
    from the answer you may understood.(just a hope)

  • 11gR2 error: call a bounded task flow with method call as default activity

    hi all,
    We migrated several applications to the JDev 11g R2.
    There are 2 applications that contain a bounded task flow where we define Method Call as default activity.
    We need invoke specific actions before opening the page.
    They run well with 11gR1.
    But with *11G R2*, I can’t call directly this task flow with the following URL:
    http://127.0.0.1:7101/MyAPP/faces/adf.task-flow?adf.tfId=my-flow-def&adf.tfDoc=/WEB-INF/flows/my-flow-def.xml
    Message:
    *<SecurityUtils><invokeURLAllowed> ADFc : impossible to call directly the task flow '/WEB-INF/flows/ my-flow-def.xml #my-flow-def' with the help of URL*
    (original message: <SecurityUtils><invokeURLAllowed> ADFc : impossible d'appeler directement le flux de tâches '/WEB-INF/flows/ my-flow-def.xml #my-flow-def' à l'aide de l'URL.)
    Any idea?
    Thanks for you help

    Hi,
    Have a look at the task flow properties, in PatchSet1, a new feature "invokeURLAllowed" is added that prevents bounded task flows from being URL accessible for security reasons. You can swithc this feature on and off
    Frank
    Ps.: I though that bounded task flows that you call from a URL generally needed to have a viewActivity as the default activity

  • Button Actions are not working -invoking task flow from other project regio

    Hi
    I have a project using a mani.jspx file having a regions and the region is updated with different views based on a router condition in my bounded task flow. Everything working fine with in the project. I have a seperate project in my application having an index.jspx and region in it. I created the ADF lib jar file of the first project and imported to this project. I could invoke the task flow in the first project to the region in the index.jspx file in the seconed project.But none of the action managed bean method attached to the buttons in this view are working.The methods are not getting called on clicking on button and no error in the backend console of Integrated weblogic server.Any body can help what could be the issue ?
    Thanks

    The issue that is happening when I refreshed the region with task flow from the project I imported.If I load the taskflow from the imported project on first time rendering all my managed bean actions are executing but if I load a different flow initially and change the taskflow Id imported from other project none of the managed actions are working.
