Bounded task flow not executing in a default view activity.

Hi,
I am practising Region to Region Interaction between two bounded taskflows in an unbounded task flow.
I will just illustrate the theme:
*Unbounded task flow[ DEfault view activity(view1)]*
view1 contains Bounded task flow task 1 and task2.
task 1 contains fragment frag1 .
task 2 contains fragment frag2. I want to establish communication between task 1 and task2 through contextual events.
I have created managed bean seperately for each bounded taskflow bean1 in task1 and bean2 in task2 which are in session scope that is frag1 vaues are maaped to bean1 and frag 2 values are mapped to bean2.
I completed full flow of creating contextula events and event map too. I was stuck with errror.
So I created an application only with default view activity containg boundsed taskflow and fragments and respective beans without contextual event and event map , so that i can make sure atleast my basicview is executing properl;y. But I failed to have result.
Error is shown below:

The error logs point to an error in your EL that references the frag1 bean. Firstly, rather than use session scope you must consider using pageFlowScope for your managed bean.

  • 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

  • Role Grants to Bounded Task Flow not Recognized on standalone WLS 10.3

    Jdeveloper 11G Build 1188
    Weblogic 10.3
    I receive this error
    oracle.adf.controller.security.AuthorizationException: ADFC-0619: Authorization check failed: '/WEB-INF/menuflow.xml#menuflow' 'VIEW'.
    This occurs before and after security migration.
    I have spent 4 days on this problem and read and re-read Jdeveloper and Weblogic docs and all the blogs I could find as well as this forum.
    The security works fine using Integated WLS.
    It seems to me that the roles in Jazn and the roles I setup in Weblogic are NOT being associated
    I followed step by step the blogs concerning security migration, weblogic standalone install, weblogic setup as to rolls and groups, etc.
    Before I go through every step I took, I would like to know If anyone has received this error.
    Chuck

    Hi Frank,
    I copied the <jazn-policy> section from the jazn-data.xml to system-jazn-data.xml and it is working
    So as expected something wrong with the migration...I will check what
    Thanks

  • ADF : Can we skip the default activity of ADF train in bounded task flow.?

    Hi All,
    I'm a newbie for ADF and JDev. Started learning from the documentation provided for ADF, I'm trying to create a bounded task flow which has a train component and every train stop should be enabled/skipped programmatically. I'm able to skip the train stops after reading the content provided at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/82-programmatically-navigate-trains-396873.pdf.
    But I'm not able to skip the default train stop which is the first activity call in my case upon initialization.
    Below are the steps I've followed :
    1. Created a viewController project and created a bounded task flow in it with Train component enabled.
    2. Added 4 views with train component marking the first view as default activity call.
    3. As per the document I mentioned above, I added managed bean files to skip the train stop programmatically.
    Now when i run the task flow, I'm able to skip the train stops number 2/3/4 but I'm not able to skip the stop number 1(first stop which is the default activity) on initialization.
    As per ADF documentation, for a bounded task flow there must be a default activity assigned which will always be called first when we enter the bounded task flow. So that means, default activity will always be called upon initialization of that bounded task flow and never be skipped programmatically.? or else if there is a way to skip the default activity, then please let me know the documentation/steps to do this.
    Thanks in advace.
    Edited by: 1004973 on May 9, 2013 2:52 AM

    Thanks Timo. Your idea resolved my issue. :)
    I've created a new page in my bounded task flow which I've made as a default activity for that bounded task flow. Then I applied navigation through router and based on some condition I'm now able to move my control to my desired train stop. By this design I can do other customization on train button(Back/Next).

  • How to create a page-definition for bounded task-flow?

    I should be able to create a page definition which declare all bindings required for a bounded task flow.
    How do I do it in JDeveloper 11.1.1.2?
    How do I navigate to the page definition when I am in the bounded task flow "Diagram tab"?

    I found out the following:
    1. To create a page-definition file for a bounded task flow
    Right click on the "Default" activity (not a view activity) of the bounded task flow, select "Create Page Definition" from the context menu.
    2. To go the page-definition file for a bounded task flow
    Right click on the "Default" activity (not a view activity) of the bounded task flow, select "Go to Page Definition" from the context menu.
    My new question is:
    In JDeveloper 11.1.1.2, how do I create page-definition for a bounded-task-flow if all activities are view activities (page fragments) ?
    How does JDeveloper I want to create page-definition for the task-flow instead of create page-definition of the page fragment or the page?

  • 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

  • Bounded Task Flow is not rendering

    Hi all,
    I am very new to ADF. I have a problem related to bounded task flows. I created bounded task flow with two simple steps like ViewX.jsff and EditX.jsff. Then I created a jsf page and put a splitter into main frame. On the left side of splitter, the master data of X is placed as read-only table. And in the right side of the splitter, I draged and dropped bounded task flow. It is render properly in jdeveloper editor, however when i run the page, bounded task flow is not displayed. I did some solution research about this problem in the forum. I implemented ADF Authentication and Authorization with HTTP Basic Authentication. I dont want a login form. I gave grants to anonymous-role and authenticated-role but it is still not working.
    Indeed, I dont want to implement a security procedure at the moment. However, if i disable security, application throws an error message about permissions. Also, is there a way for running bounded task flow while security is not enabled?
    Jdev Version: 11.1.2.2 JSF 2.0
    Sorry for bad English.
    Regards.
    Anil.

    Hi,
    I have already given grants to Bounded Task Flow. However it is still not displaying when i run the page.
    If i disable security, i am getting the following error log when i run a page with bounded task flow.

When the bounded task flow is invoked, I am presented with a dialog which contains a "404 Not Found" error. I thought that I had this right based on what I read in the developers guide:
    1. In my unbounded task flow, create a task-flow-call activity
    a. Set the "Run As Dialog" behavior to "true"
    b. Set the "Display type" to "inline-popup"
    2. Add a named control flow which associates a view activity to the task-flow-call activity.
    3. In the related view activity page, add a command control with the "action" set to the name of the control flow, and "useWindow" set to "true".
    4. In my bounded task flow, add a view activity which points to the JSF document (jsfx) that I want to display in the dialog.
    5. I add a task flow return activity to my bounded task flow, and a control flow that associates the view activity with the return activity.
    6. In my page fragment, I add a cancel button which invokes the control flow from the view activity to the return activity.
    Run
    When I click on the command button which invokes the bounded task flow as an inline pop-up, and I see an inline pop-up which contains the 404 page not found error.
    I must be missing something fundamental here. I've scanned all the doc and the forum, but I don't see it. Will someone please point it out to me?
    Cheers

    I appreciate the response, but I am actually building an ADF application that I am running in the JDeveloper embedded WebLogic Server. These instructions are for deploying a task form composite app to a standalone WLS.
    I'm just trying to run a bounded task flow in a dialog as described here: http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/taskflows_dialogs.htm#BABBAFJB
    However, I get the 404 Not Found error when I invoke the bounded task flow from a command control. The dialog appears, but the default page of my bounded task flow is not in it.
    Seems like this has to be a simple problem to fix. Anyone?
    Thanks

  • Can not commit when using region in bounded task flow

    Hi All
    I am using Jdeveloper 11g R2 (11.1.2.3) & Weblogic 10.3.5.0
    I have 2 bounded task flow in my application (A and B)
    Each contain a fragment with few tabs (using af:panelTabbed)
    I have another common functionality in this 2 bounded task flows
    So I create another bounded task flow and add it as a region in tabs in task flows A and B
    But when I am going to the common tab and insert record and commit using task flow commit it is not commit records in database
    Is something wrong ? Any ideas how I can fix it?
    Regards
    Mohsen

    Hi Frank
    I am using below code for commit (from TaskFlowUtils class)
    public void commitTaskFlow() {
    getDataControlFrame().commit();
    public DataControlFrame getDataControlFrame() {
    BindingContext bindingContext = oracle.adf.controller.binding.BindingUtils.getBindingContext();
    String dataControlFrameName = bindingContext.getCurrentDataControlFrame();
    DataControlFrame dataControlFrame = bindingContext.findDataControlFrame(dataControlFrameName);
    return dataControlFrame;
    Your comment was too helpful , I change data control scope to shared and it is working now
    One more related question:
    Is adding bounded task flow into another fragment as region an advised approach?
    Thanks a lot

  • How to pass a parameter to a bounded task flow?

    Hi,
    We are facing issue while passing parameter from a bounded task flow to another bounded task flow and then showing the passed parameter in a jspx page.
    We have a caller task flow with following component:
    1. A jspx page
    - In this jspx we have a text box have its value as #{pageFlowScope.inputvalue}.
    - Also we have a command button which has its "Action" as the control flow that leads to the "called" task flow.
    2. A bounded task flow named "called".
    So, we call the "called" task flow on the button click in the jspx page.
    Also, in called taskflow we have a jspx page where we are using a output label to show the parameter passed from caller task flow to the called task flow.
    We performed the following steps to set the parameter passing from caller task flow to the called task flow.
    1. Select the input text component on the JSF page.
    2. In the Property Inspector, enter a value for the input text component. You can specify the value as an EL expression, for example #{pageFlowScope.inputValue}.
    3. In the Application Navigator, double-click the name of the called task flow to open its diagram.
    4. Click the Overview tab for the called task flow.
    5. Click Parameters and expand the Input Parameter Definition node.
    6. Click the Add icon next to Input Parameter Definition.
    7. In the Name field, enter a name for the parameter, for example, inputParm1.
    8. In the Value field, enter an EL expression where the parameter value is stored and referenced, for example, #{pageFlowScope.inputValue}.
    9. In the Class field, enter a Java class for the input parameter definition. If you leave the Class field empty, its value is by default implicitly set to java.lang.String.
    10. In the editor, open the diagram for the calling task flow.
    11. In the Application Navigator, drag the called ADF bounded task flow and drop it on top of the task flow call activity that is located on the calling task flow. Dropping a bounded task flow on top of a task flow call activity in a diagram automatically creates a task flow reference to the bounded task flow.
    12. In the Property Inspector for the task flow call activity, click Parameters and expand the Input Parameters section.
    13. Enter a name that identifies the input parameter.
    14. Enter a parameter value, for example, #{pageFlowScope.parm1}.
    Now when we try to fetch the value of parameter using #{pageFlowScope.parm1} in the jspx in called taskflow, its not giving the desired value.
    We even tried to set the to and from parameter of the jspx in called askflow. But no success.
    Can anyone let us know if we are doing smething wrong or exact steps to configure passing of parameters to a bounded task flow and retrieving it in a jspx page will also help.
    Thanks in advance.

    Hi Tushar,
    In step# 14, the value should be "#{pageFlowScope.inputValue}" (should be the same as the value in step#2) .

  • 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.

  • Bounded-Task-Flow Page Fragment Control Flow Help

    jDeveloper: 11.1.1.0.2
    I am having an issue trying to figure out the correct way to use control flow cases between a bounded-task-flow with page fragments and an unbounded-task-flow page. We have taken the approach in our application to have a few shell / container pages to host bounded-task-flows made up of page fragments to facilitate re-usability and to speed up development. There are 4 or 5 shell pages on the applications unbounded-task-flow. As of now, we have about 20 page fragments that are implemented as bounded-task-flows. These fragments don't do much now, meaning there is only a single fragment in each bounded-task-flow. The issue I am having is trying to invoke a control flow navigation action from one of the fragments to load a different shell page.
    For Example, shellPage1.jspx contains fragment-flow-1 as a region. In my adfc-config.xml I have shellPage1.jspx and shellPage2.jspx, with control flow cases "toShell1" and "toShell2" respectively connecting the two pages. I have a link's action bound to the "toShell2" within the fragment that makes up fragment-flow-1. When the application is run, shellPage1.jspx and its fragment are displayed. But clicking on the link in the fragment ("toShell2") does absolutely nothing. It does not navigate me to the shellPage2.jspx as expected. What am I doing wrong here or do not understand?
    If the fragment is included as a JSP include, and not a bounded task flow include, everything works as expected. This is not desirable as we then need to copy the fragment's pageDef into the shellPage's pageDef to get the DataControls to function.
    If the faces-config.xml is used instead, and a JSF navigation case is used, it will also work as expected. This is not desirable because we really don't want to be mixing adcf-config and faces-config.
    So I am really stumped here.... Thanks in advance!

    Hi there:
    In your case, the adfc-config.xml has the control flow case between shell pages. And the task-flow-N.xml or your-task-flow.xml for each page fragment by default doesn't inherit control flow case from their containing shell page. In your case, in the page fragment task-flow.xml, you should add a "Parent Action" to flow to shell page2 for example. The outcome of "Parent Action" would be "toShell2" if calling from ShellPage1 page fragment.
    Is this 'Correct' or 'Helpful' for you? Please mark it as so if it does.
    Good luck,
    Alex

  • Call a bounded task flow from within another bounded task flow

    Hello
    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.

    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 =(

  • Can I reference page-flow bean from a bounded-task-flow page-fragment?

    I have a view activity implemented as page fragment in my bounded task flow.
    I declare a page-flow scope managed-bean in adfc-config.xml to do some initialization for the bounded-task-flow:
    <managed-bean id="__23">
    <managed-bean-name id="__22">TaskFlowBean</managed-bean-name>
    <managed-bean-class id="__21">view.backing.TaskFlowBackingBean</managed-bean-class>
    <managed-bean-scope id="__20">pageFlow</managed-bean-scope>
    </managed-bean>
    In my bounded task flow, the default activity is a method-call activity which call the page-flow bean method
    <method-call id="initFlow">
    <method>#{pageFlowScope.TaskFlowBean.initFlow}</method>
    <outcome id="__27">
    <fixed-outcome>showPanel</fixed-outcome>
    </outcome>
    </method-call>
    But JDeveloper (11.1.1.2) show a warning "Refereneed pageFlowScope not found" at the "Diagram" view of the flow definition.
    The fixed outcome of the default activity is to render a page-fragment which also reference the page-flow scope bean method getPanelTitle():
    <af:panelBox text="#{pageFlowScope.TaskFlowBean.panelTitle}" id="pb1">
    <f:facet name="toolbar"/>
    </af:panelBox>
    At runtime, the page fragment was rendered properly except the panel box title is missing. No other error is reported
    When I debugged the application, the bean methods initFlow() and getPanelTitle() didn't get call as the program didn't stop at the breakpoint set in the bean methods.
    The page fragment was rendered properly except the panel box title is missing.
    When I change the scope to backing bean, both initFlow() and getPanelTitle() get called but under a different backing bean.
    As the bean attributes set by initFlow() were not no longer set when getPanelTitle() was invoked even though the methods were invoked in the correct order.
    Why can't I use a page-flow scope bean within the bounded task flow?
    On further debugging, I noticed the bean was not created when it is set to be page-flow scope. I put a debug message in the constructor... never get called.
    When should a page-flow scope bean be created to be accessible on entry to a bounded task flow?
    Edited by: Pricilla on Apr 29, 2010 3:16 PM

    Please check the scope of the pageFlow from the manual.
    pageFlowScope is only available for the pages/views in that taskflow and not in the included taskflows.

  • ADF Bounded Task Flow

    I have created a bounded task flow which has the following activities: Method Call (default activity and it calls a custom method in a request scoped backing bean), a controlFlow to a jsf page, a controlFlow to a Task Flow Return.
    Here is the xml code for the Bounded Task Flow:
    <?xml version="1.0" encoding="windows-1252" ?>

    I am calling this bounded task flow from a commandLink that is in an ADF table (partial code of the jsf page that has the commandLink):
    <af:table value="#{bindings.VProjectlistQryVO1.collectionModel}" var="row"
    rows="#{bindings.VProjectlistQryVO1.rangeSize}"

    When I click the commandLink where the action is the bounded task flow (fromviewprojlist-task-flow), it does not go into the method I am specifying in the Method Call activitiy (the default activity) within the task flow. It does not error out, but it does not go anywhere. My objective is to go to the custom backing bean method so I can get some value of the row in the table I clicked on, then use this value to successfully load the projSummary.jsf page
    I am new to this, and I can't figure out what I'm missing. I appreciate any ideas you may have to help me resolve this.
    Thanks!

    I did as you suggested, but I see nothing in the console that indicates it's trying to run the bounded task flow. It's like it ignores it. No error, just redisplays the page I'm calling the bounded task flow from.
    Previously, in another application, I created a bounded task flow with the default activity which was a Method Call activity, but I dragged and dropped a createInsert operation onto the Method Call activity from the Data Control. This worked fine (for creating an inputForm).
    With this bounded task flow that is giving me problems, I'm not referencing the Data Control at all, I'm just referencing the method in the request-scoped backing bean. Is there something I don't have "wired up" correctly so that it's not even finding the bounded task flow the action attribute of my commandLink is referencing?
    I'm not referencing the model (or an application module) at all, but should this matter? It seems like it should just find my backing bean method, run it, and carry on!
