Question on Task flow return

Hi ,
I have the following questions on Task flow return:
i) I have a Task flow 1 (TF1) . I call Task Flow 2 (TF2) from TF1 using openMainTask method to open TF2 in a new tab. In TF2, I have a task flow return activity. What is the expected behaviour of Task flow return in this case?
ii)The End Transaction of task flow return in TF2 is 'commit'. The Transaction behaviour is 'Use Existing Transaction if possible' . Is it possible to set the End Transaction to default (none). When I try to set it to default none, it errors out. I have a bean code on the Save and Close for commiting the data and I do not want the Task flow return to commit again.
iii)Which method is internally called on Commit of a task flow return?
Thanks !

Hi,
if the task flow shares the DataControl with the calling task flow then the transaction mode can be none. If the task flow is isolated (not sharing a DC) then the task flow must commit or rollback

  • ADF task flow return redirect to page?

    Hello, I am using JDeveloper 11.1.2.3.0
    I have build a task flow (bounded task flow) in my application and I want to redirect on task flow return, to another page from the application. This page is not part of the flow. From what I am reading till now everything I found is to call another task flow on return, but I do not need this. I just need to redirect to a specific page. Can anyone help on this?
    Thank you

    Thanks but is there no possibility at all to navigate to another page within the aplication (not of the same task flow)? I was thinking something like FacesContext.getCurrentInstance().getExternalContext().redirect("Page1") on action method on a button of the page; But I am getting an error saying that can not find the Page1.

  • Task Flow Return Listener not fire when FK association fields set manually

    Guys and Gals,
    I've spent two solid days on this and I'm not sure why my task flow return listener is not firing.
    I start by selecting a row in a table. I then click a "Convert" button which converts the Quote document into a Sales document. I then press Submit which commits the data and the task flow exits. At this point my task flow return listener should fire. It does not. This return listener would, in theory, refresh the visible Quotes table and update the selected Quote's status to "Closed".
    The Quote's "Closed" status is a transient attribute which is calculated by looking at the Sales' document Qty attribute. If the Quote Qty = Sales Qty, then the status is closed. This can be measured by utilizing an association where
    Sales' BaseRefDocId = Quotes' OrderId
    Sales' BaseRefRowId = Quotes' RowId
    Setting these two row attributes represent the association linking a Quote document row to a Sales document row.
            nvp.setAttribute("BaseRefDocId", baseRow.getAttribute("OrderId"));     // Take the Quote Id and put in the Sales' Id ref field
            nvp.setAttribute("BaseRefRowId", baseRow.getAttribute("Row_Id"));    // Take the Quote Row Id and put it in the Sales Row Id ref field
            targetRow.createAndInitRow(nvp);                                                    // Insert the new referenced row into the Sales' DocumentAfter two days of running tests, it is the code above that keeps the return listener from firing and the transient attribute from refreshing on the page. These fields are not mandatory, but are necessary for the Quotes status to change to closed. Simply leaving these lines of code out allows my task flow return listener to refresh correctly, albeit with an incorrect Quote status.
    My expression language statements, however, evaluate correctly irregardless of table refresh. If I refresh the table manually, the status will then display the correct value. All other methods of manipulating the table function correctly i.e. task flow return statements work.
    I'm pretty sure it has something to do with some kind of silent association / view link error blocking the task flow from firing behind the scenes.
    Does anyone have any ideas? Using JDev 11.1.2.1.0.
    Will

    Hi Frank,
    Yeah, I thought it was really weird as well. I banged my head up against the wall again today and finally managed to semi-fix the problem.
    The "Convert" table toolbar button has a "Disabled" attribute that I've been setting with something like #{bindings.QuoteIterator.currentRow == null}. If I take this out, everything works fine. However, if I put it in, the task flow will not return. What's screwy is that I have several of these "Quote" tables for other data collections such as Sales, Deliveries, Invoices, etc. About half of them fire a task flow return with the "Disabled" attribute set for the convert button, and the other half don't. They all return a task flow return if I just set "Disabled" to false.
    At three days and counting, this is really an issue I just don't get, and I'm not sure if I could reproduce the problem to submit it to support because everything appears just fine and I've been digging for days.

  • Bounded task flow task-flow-return to unbounded task flow throws 404

    I'm using an unbounded task flow (adfc-config.xml) to call a bounded task flow (task-flow-definition). All navigation in the bounded task flow works well, data is committing. (I am omitting many of the pages from the bounded task flow to keep this post shorter. If I can get this first page to return to the unbounded task flow, I can copy it forward.)
    My problem is when running from the unbounded task flow, I cannot seem to configure the bounded task flow to return to the login page inside the unbounded task flow, which called it, without a 404 error.

    Is the task-flow-return the ONLY way to pass values from the bounded to the unbounded task flow?
    Or is it possible to use a control-flow-case inside the bounded task flow like this, that refers to the unbounded task flow to navigate from the bounded back to the unbounded task flow?

  • Region not refreshing while reentry in task flow using task flow return

    Hi,
    Use Case :
    1) I have a task flow TF1 displayed as a region in page fragment Page1. Task flow has certain input parameters. It displays a data in table which is surrounded by Panel Box which is expanded if certain input parameters are set otherwise disclosed
    2) From Parents screen we have a button , on click of that button I am navigating to a different task flow TF2 , adding some data and coming back to screen Page1 through task flow return activity.
    3) Task flow TF1 should be refreshed with new data which is being set on through a bean variable.
    Task flow TF1 is not being refreshed. (I have tried setting the refresh property to 'If Needed')
    Please Suggest.
    Best regards,
    Anu

    Hi,
    Thanks for the response. Query is being execute in the backend. But region is not being refreshed even after change of parameter.

  • Calling task flows return activity from Jspx page.

    Hi ,
    Using JDev11.1.1.6
    I have created template for home page, drag and dropped the task flow(Main Task flow) as region.
    Main task flow contains other 2 taskflows with control flows and other 2 taskflows contains Task flow return activity to navigate back to Main task flow.
    I need to call task flow return activity from jspx page.
    How it can be acheived? can you please suggest me.
    Thanks and Regards,
    Raj Gopal K

    Hi,
    My use case is to close the child task flow and navigate back to main task flow. This should be done through homePage.jspx(whch contains main task flow).
    What i have done:
    Having page template which has logout and home page links. Use this template to create homePage.jspx, Next drag the main task flow to create a region inside the homePage.jspx.

  • How to call page in adfc-config from bounded-task-flow return?

    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. I dont know if this can be done, but do you have any idea on how to achieve something like this?
    Thank you

  • Task flow return-Current Record pointing issue.

    Hi friends
    Newbie in ADF (basically from .net back ground)...........I am in the process of developing my first module.
    I have a task flow where a master detail records are displayed ..When I click "Edit" it is calling a edit task flow where the editing of master/detail tables are performed .When I click "New" a blank record is created and it is calling same edit task flow.
    my problem is when the child task flow exits and returns to the parent it is not pointing to the current record I edited...This is true if return either by commit or cancel.
    My data control is shared , parent task flow does not have any transaction and child always starts a new transaction.
    What is the ideal solution to point to the current record when I return?.
    Thanks .
    Ashraf

    Below is updated bean code
    ViewObject VO;
    FacesContext fctx = FacesContext.getCurrentInstance();
    DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
    DCIteratorBinding iter = bindings.findIteratorBinding("Delmast1Iterator");
    VO = iter.getViewObject();
    Key currKey = iter.getCurrentRow().getKey();
    Row[] rows = VO.findByKey(currKey, 1);
    if (rows.length == 1) {
    System.out.println("row found");
    VO.setCurrentRow(rows[0]);
    iter.executeQuery();
    iter.setCurrentRowWithKey(currKey.toStringFormat(true));
    iter.setCurrentRowWithKeyValue(iter.getCurrentRow().getAttribute("SaleId").toString());
    If my child task flow does not have a commit or rollback the above code works fine...But I am beginning a transaction in my child flow(edit flow) so it is a must to have commit/rollback.
    Is there any other options experts ?..Please guide me.
    Thax.

  • Best way to refresh page after returning from task flow?

    Hello -
    (Using jdev 11g release 1)
    What is the best way to refresh data in a page after navigating to and returning from a task flow with an isolated data control scope where that data is changed and commited to the database?
    I have 2 bounded task flows: list-records-tf and edit-record-tf
    Both use page fragments
    list-records-tf has a list.jsff fragment and a task flow call to edit-record-tf
    The list.jsff page has a table of records that a user can click on and a button which, when pressed, will pass control to the edit-record-tf call. (There are also set property listeners on the button to set values in the request that are used as parameters to edit-record-tf.)
    The edit-record-tf always begins a new transaction and does not share data controls with the calling task flow. It consists of an application module call to set up the model according to the parameters passed in (edit record X or create new record Y or...etc.), a page fragment with a form to allow users to edit the record, and 2 different task flow returns for saving/cancelling the transaction.
    Back to the question - when I change a record in the edit page, the changes do not show up on the list page until I requery the data set. What is the best way to get the list page to refresh itself automatically upon return from the edit-record-tf?
    (If I ran the edit task flow in a popup dialog I could just use the return listener on the command component that launched the popup. But I don't want to run this in a dialog.)
    Thank you for reading my question.

    What if you have the bean which has refresh method as TF param? Call that method after you save the data. or use contextual event.

  • Code for return from task flow

    Hi,
    I came across this TaskFlowUtils which contains utility methods related to task flow.
    Is there any method which will cause return from task Flow. I can't find the same.
    I do not want to return via Task Flow return activity.
    Regards,
    Nikhil

    Nikhil, which jdev version do you use?
    What is your use case?
    Are you referring to the class TaskFlowUtils Chris Muir developed and which is available through ADFEMG?
    If yes, this class is more to inspect the current task flow. It contains some methods to control the task flow (commit, rollback), but is not meant to navigate.
    It is essential to understand how task flows work, if they are called using a task flow call activity or if they are run in a region. A task flow run in a region is not meant to return. It always run once it initiated. There are patterns how regions communicate with their parent or other regions.
    So the question is what do you want to do?
    Why do you want to return from a task flow and why don't you want to use the task flow return activity?

  • Task flow question

    I have couple of jsf pages in adfc-config. Also, I have a bounded task flow. I want to invoke this bounded tf after users entered data in those unbounded tf pages. Thank you.

    One way to accomplish this is by calling the task flow programmatically from a backing bean. This can be done by calling ControllerContext.getTaskFlowURL() to retrieve the task flow URL and return it as an action. Here is some sample code that you will need to adapt:
    // return your task flow URL action
    public String getYourTaskFlowAction() {
        // if you are passing parameters to the task flow, add them
        Map<String,Object> parameters = new HashMap<String,Object>();
        parameters.put("yourParameter",yourParameterValue);
        TaskFlowId taskflowId = TaskFlowId.parse("/task-flows/YourTaskFlow.xml#YourTaskFlow");
        String taskflowUrl = ControllerContext.getInstance().getTaskFlowURL(false, taskflowId , parameters);
        // returning the URL, will invoke the task flow
        return taskflowUrl;
    }In order for this to work, you will also need to set the task flow URL Invoke property to url-invoke-allowed.
    Another way would be to call the bounded task flow via a Task Flow Call directly from your unbounded task flow.

  • UI Shell - how to allow ADF Library Bounded Task Flow to close itself

    Hi Richard
    Further to my other post, we're having lots of fun with the UI Shell, it's making mockups very easy.
    Question for you though based around the functionality defined in the UI Shell whitepaper. Say we've created our UI Shell application, and rather than wanting to create the bounded task flows in the app (ie.first, second, third), we create them as standalone bounded task flows deployed to ADF Libraries, and imported into our app separately.
    In the UI Shell examples bounded task flows are opened & closed via the UI Shell's own components (say the navigation page items or toolbar buttons), that call the methods in the Launcher bean (_launchActivity & closeCurrentActivity). It's fairly simple to rewrite the launcher helper methods in the launcher bean to call an imported ADF Library bounded task flow to open it as an activity, just referencing the correct task-flow.xml file.
    However as you know a bounded task flow has a "Default Activity" entry point and one or more "Task Flow Return" exit points. What I haven't been able to work out is how when the bounded task flow exits via a task flow return, can we call the closeCurrentActivity method in the Launcher bean? The UI Shell code examples demonstrate closing a bounded task flow by menu options/or similar outside the bounded task flow in the UI Shell, but it would seem reasonable if the bounded task flow exited via a "Task Flow Return" we should be also able to close the activity tab too.
    (....and as extension, before we even do that potentially call the checkState/isDirty() method to stop the user closing the activity too, but again driven by the bounded task flow attempting to exit).
    I could imagine inserting code into the bounded task flow finalizer to close the activity tab, but this pushes the UI Shell tab activity management logic into our standalone ADF Library bounded task flows which isn't ideal, especially if we want to later reuse them in another app which doesn't use the UI Shell.
    Any suggestions welcome.
    Thanks & regards,
    CM.

    And we're back again.... what's a couple months between friends?
    So it turns out after testing our app ([email protected], so close) that we've hit a bug with this approach.
    Our current app allows one BTF to be open in the UI Shell at any one time. Our menu options automatically open one BTF at a time by the user (max one open), and close the previous BTF. However we have some "special" BTFs that require the user to explicitly close the BTF, which in turn makes use of the regionNavigationListener solution I described earlier in this post.
    However we discovered a bug when we do a complete cycle of the 15 embedded regions within the UI Shell.
    Say we:
    1) Open a normal BTF in region 0
    2) Open another normal BTF in region 1 (our solution automatically closes the previous BTF)
    3) We then open another BTF (again the previous BTF is closed) in region 2, yet this a "special" BTF requiring the user explicitly to close it. Upon the user closing the BTF - this results in the regionNavigationListener being called and the removeTab() method called to close down the BTF in the UI Shell
    4) The user then open/closes multiple normal BTFs, one by one, rotating through regions 3, 4, 5 .... eventually back to 1 again
    5) Then the bug occurs - on opening any BTF back in region 2 (as part of the complete cycle of all regions), the tab for the region 2 opens, correct title, and via debugging the Tab.class has all the right settings including taskFlowId, but the tab is incorrectly empty
    doh!
    I've managed to track a symptom of the problem down that may explain what's happening.
    Each time a tab is rendered with a BTF, the Tab classes getBinding() method returns a reference to the binding required for the current BTF. However for some reason on the complete cycle, for "r2" it returns the binding for the previously user-closed BTF from step 3 above, even though we called the TabContext.removeTab() method.
    What I haven't been able to work out is how the bindings get turned on/off dynamically for each BTF being invoked. Presumably for some reason on step 3, the BTF's bindings aren't being correctly removed from r2 even though we called TabContext.removeTab().
    If anybody has any brain waves about what's going on and how to fix this problem, your help appreciated.
    Regards,
    CM.

  • Af:table filter date format : task-flow navigation issue

    hi
    When trying to use the date format configured on the Entity Object, with Format Type as Simple Date and Format as "dd-MM-yyyy", there seems to be a problem when using task-flows.
    The approach involves an explicitly configured attributeValues binding to use in f:validator and af:convertDateTime components in the af:inputDate in the filter facet, as discussed in the forum thread "af:table filter date format"
    at af:table filter date format
    I used JDeveloper 11.1.1.3.0 to create the example application
    in http://www.consideringred.com/files/oracle/2010/TableFilterDateFormatIssueApp-v0.03.zip
    - The page filterEmp.jspx shows expected behaviour, the filter uses the configured date format and there is no problem when navigating to another page and back.
    see the screencast at http://screencast.com/t/CtQ9rsVFH3k
    - The page menuBTFPage.jspx allows for some navigation after using the filter resulting in the filter showing a date in the wrong format, using scenario (sc1)
    -- (sc1-a) : run menuBTFPage.jspx
    -- (sc1-b) : on "menu-btf : menu", click the "do go-filter-emp-btf" link
    -- (sc1-c) : on "filter-emp-btf : filterEmpFragment", filter on HireDate using "10-03-2005"
    -- (sc1-d) : click the "do goReturnSuccess" button
    -- (sc1-e) : back on "menu-btf : menu", click the "do go-filter-emp-btf" link again
    -- (sc1-f) : back on "filter-emp-btf : filterEmpFragment", see the HireDate filter value in the wrong format as "2005-03-10"
    -- (sc1-g) : click the "do goReturnSuccess" button again, which results in an error "The date is not in the correct format."
    see the screencast at http://www.screencast.com/t/ORHauBd3oQ
    questions:
    - (q1) Can the behaviour in scenario (sc1) be reproduced?
    - (q2) Why is the filter value in the wrong date format in step (sc1-f)?
    - (q3) What can be done to have the filter value consistently in the configured date format, so that errors as in step (sc1-g) can be avoided?
    many thanks

    hi
    First a short summary of relevant aspects of service request 3-2190488381:
    - development has reviewed bug 10193260
    - development identified some code where a pattern was not applied and started fixing the problem
    - out of the blue, development asked "Will clearing out the filter field completely when moving out of ataskflow be an acceptable behavior ?"
    - I pointed out some concerns (even in a phone call with development), but development did not see any alternative not "perceived to be very risky because of the current design", so the question whether the clearing-all-filter-fields approach would be acceptable became superfluous.
    - following this, bug 10193260 suddenly became an enhancement request (for reasons I still don't understand)
    - a workaround was suggested (for behaviour not perceived as a bug), "Clearing the search fields during taskflow exit in the backing bean (in the app)." for which I also received a modified version of my example application TableFilterDateFormatIssueApp-v0.04.zip with an implementation of the suggested workaround
    As an exercise to try an understand the suggested workaround (an because my example application seemed to have been modified using the currently yet-to-be-released JDeveloper 11.1.1.4.0) I re-implemented it in the example application
    at http://www.consideringred.com/files/oracle/2010/TableFilterDateFormatIssueApp-v0.05.zip
    It has a filter-emp-workaround-btf task-flow with a method-call activity on a managed-bean method, responsible for clearing the search fields, resulting in behaviour where the error "The date is not in the correct format." does not occur,
    as can be seen in the screencast at http://screencast.com/t/Nq7TkkRQ
      public void clearFilterFields()
        BindingContainer vBindingContainer =
          BindingContext.getCurrent().getCurrentBindingsEntry();
        DCBindingContainer vDCBindingContainer = (DCBindingContainer)vBindingContainer;
        DCDataControl vDCDataControl = vDCBindingContainer.getDataControl();
        ApplicationModule vApplicationModule = vDCDataControl.getApplicationModule();
        ViewObject vViewObject = vApplicationModule.findViewObject("EmployeesVOVI");
        ViewCriteriaManager vViewCriteriaManager = vViewObject.getViewCriteriaManager();
        vViewCriteriaManager.clearViewCriterias();
        vViewObject.clearCache();
      }Because the managed-bean method requires access to the ADF Model binding layer to get to the View Object instance used for the filtered table, the method-call activity has a page element configured in DataBindings.cpx referring to the same usageId as the page element for the page fragment showing the filtered table. So that both the method-call and view activity depend on one and the same Binding Container (e.i. PageDef file).
    The method-call activity, responsible for clearing the search fields, would need to be called before each task-flow-return activity.
    As there can be multiple view activities with multiple filtered tables in a bounded task-flow, would that result in multiple method-call activities responsible for clearing search fields (all to be called before each task-flow-return activity)?
    It looks like a more general/generic approach is desirable for the suggested workaround to be feasible.
    - (q5) Does the suggested workaround imply (as bug 10193260 is not a bug) that all bounded task-flows with filtered tables should implement it to avoid errors about formatting?
    thanks

  • Problem with ADF security and task flow calls

    Hi.
    I am using JDeveloper 11.1.2.0.0.
    I encountered a problem when tried to apply ADF security to my application.
    The way to reproduce the problem:
    1. Create new Fusion Web Application;
    2. Import Business Components from Tables from any existing schema and add at least one table to the ApplicationModule.
    3. Create "welcome page" (for instance, welcome.jsf). Add a button with fixed action outcome "test".
    4. Create test page, for instance, test.jsf. Drag and drop any view object from Data Controls onto the page and create a form with navigation controls. Add a button with fixed action outcome "return".
    5. Create bounded task flow, name it "test", drag and drop our test page on it - the page will be the default activity. Add a task flow return activity. Add a control flow case from the default view activity to the return activity, set From Outcome property to "return". So our return button should cause the task flow to exit.
    6. Open adfc-config.xml in diagram mode and place our welcome page on it. Then drag and drop the test task flow to create a task flow call activity. Add a control flow case from welcome page to task flow call activity, set the From Outcome property to "test". So our test button should call the test task flow.
    7. Configure application to run the unbounded task flow starting with Welcome view activity.
    At this point all works as expected: when application runs, the welcome page is displayed with test button. Pressing the test button results in displaying the test page, return button leads back to the welcome page.
    Now let's configure ADF Security.
    Run the ADF Security configuration wizard, choose ADF Authentication and Authorization.
    On the second page select Form-Based Authentication, check the Generate Default Pages flag.
    On the third page choose No Automatic Grants.
    On the next page keep the Redirect Upon Successful Authentication unchecked. Press Finish.
    Open jazn-data.xml to configure roles, users and resource grants:
    1. Create application role test-role.
    2. Grant the test-role privileges to view the test task flow.
    3. Create user and grant him the test-role.
    Now we have the public available welcome page and the test page with restricted access.
    When application runs, the welcome page is displayed as expected. Pressing the test button redirect us to auto-generated login page. After successful authorization the test page is displayed. But nothing happens if we click now the return button for the first time. When we click the return button once more, the application crushes with Error-500 and message "Target Unreachable, identifier 'bindings' resolved to null". The exact error trace depends on UI control bindings, but looks like this:
    javax.el.PropertyNotFoundException: //C:/Users/DUDKIN/AppData/Roaming/JDeveloper/system11.1.2.0.38.60.17/o.j2ee/drs/Test1/ViewControllerWebApp.war/test.jsf @10,120 value="#{bindings.Id.inputValue}": Target Unreachable, identifier 'bindings' resolved to null

    (the rest of lines skipped).
    Any suggestions?

    The welcome page is public available since it does not have appropriate PageDef file.
    Login page comes not from the welcome page, it comes after attempt to access the test page. So after the login succeeded the test page appears, because redirect to welcome page after successful login is not configured. I do not need to return the welcome page at this moment, I need to go to the test page.
    It seems the task flow call stack to be destroyed after redirect to login page.
