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 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.

  • 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.

  • How to invoke different pages/bounded task flows from Radio Group faces control ?

    Hi,
    I am quite new to JDeveloper and Java. Trying to call three different pages/bounded taskflows depending upon the each selection of radio buttons in Radio Group of 3 Radio buttons.
    Advance appreciation for hints/guide line for doing the same.

    Hi,
    I can't code it for you, but the way it works is that you create navigation cases to the pages and task flows. Then you set autosubmit=true for the radio group component and define a value change listener. The value change listener then would do the navigation following the navigation case names determined by the radio settings.
    To implement this I suggest to
    1. create a hidden command button with its action property pointing to the same managed bean handling the value change event (just double click the button to create the managed bean method)
    2. In the value change listener, change the navigation case returned by the action method
    3. In the value change listener you call
      ActionEvent ae = new ActionEvent(   (RichCommandButton)valueChangeEvent.getUIComponent().findComponent("button_id"));
      ae.queue()

    and How to pass this from URL

    Hi,
    url-invoke-allowed is only required if the task flow itself is directly accessible from a browser (which is not the case at all if the task flow uses page fragments). To pass input parameters to a task flow that is embedded in a region and that has input parameters, you define the input parameters on the taskFlow Id that is created in the PageDef file of the containing page. To learn ADF task flows, have a look at the videos below. They also contain a sample for passing parameters to a region

    Hello everybody, I am using JDeveloper 11.1.2.3.0
    I have in my adfc-config some pages and one bounded-task-flow (with pages, not page fragments). I call the bounded task flow from one of my pages but I want that when I return from the bounded-task-flow to redirect the page to another page rather than the page that called it.

  • Doco/functionality mismatch: Adding a Bounded Task Flow to a Page

    Hi JDev team
    With JDev 11g TP4 and the latest published ADF Guide in hand, under section 14.3 "Adding a Bounded Task Flow to a Page", subsection "To add a bounded task flow containing pages to a JSF page:" it notes that when you drag n drop a bounded task flow from the App Navigator into a JSF page you get the choice of creating a button or link. I don't get this option, instead I can create a region or a dynamic region in the drag n drop submenu.
    Cheers,
    CM.

    Chris,
    note that it says "containing pages", not "containing page fragments". If your taskflow contains page fragments "jsff" then the choice is a region, if it is pages (jspx) then the choice is button or link to launch the taskflow.
    Let me know if this still doesn't work for you

  • Run bounded task flow as start point in an unbounded task flow

    Hi,

    how can I call the bounded task flow from the adfc-config.xml unbounded task flow directly , in other words to be the first activity to run ?
    I can not have a first page calls my bounded task flow?
    thanks

    hi,
    thanks for replying,
    I am testing exactly what u have posted, but I receive the HTTP 404 error :
    From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

    The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
    If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead.
    The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism,
    that an old resource is permanently unavailable and has no forwarding address.where does the flow supposed to go upon reaching a return activity
    The case is simply as follows,
    my task flow represents a simple transaction, starts in the main activity, finishes with a return activity , how can I set the task flow to re-enter the cycle again , upon reaching the return activity, if I am not using an unbounded task flow ?

  • Bounded Task Flow as Dialog - 404 Not Found

    I am attempting to call a bounded task flow as an inline dialog from a view activity in my unbounded 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?

    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

  • 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:

    (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

  • Can ADF Faces Dialog Framework be used in a Bounded Task Flow ?

    Jdev. 11.1.1.4
    I have read chapter "19 Using Dialogs in Your Application" in the Jdev documentation.
    There explains that there are mainly two methods to open dialogs in ADF:
    The first (point 19.2) is calling a bounded task flow from a view activity (for example). This system can only open modal windows.
    The other is using the ADF Faces Dialog Framework and it seems to be more general. In point "19.3.1 How to Define a JSF Navigation Rule for Opening a Dialog" it is explainied the way to achieve this but the explanation begins with "In the adfc-config.xml file, create a page flow for".
    does this mean that I can not use this technology inside a Bounded task flow ?
    I have tried and it seems that it doesn't work.
    Currently we are using af:showpopupbehaviour to open popups, but this doesn't work with task flows and I don't like this.

    does this mean that I can not use this technology inside a Bounded task flow ?ADF Faces Dialog Framework can be used in both unbounded and bounded taskflows.
    I have tried and it seems that it doesn't work.The command commponent outcome must begin with "dialog:" and the command component tag must have useWindow="true", for example:
    <tt><af:commandButton action="dialog:toEdit" useWindow="true" .../></tt>
    Currently we are using af:showpopupbehaviour to open popups<af:showPopupBehaviour> can be used to open inline popups, but it has nothing to do with the Dialog Framework. Inline popups and the dialogs of the Dialog Framework are two different things.

    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!

  • Pass parameter from one jsff to other in bounded task flow

  • 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) .
