Bounded Task Flow Navigation Issue

Hi,
I'm using Studio Edition Version 11.1.2.3.0.
I have a main page with a panel splitter. The right side has a dynamic region and the left side contains links to launch a bounded task flow in the dynamic region.
One of my task flows is a search form and has a call to another bounded task flow when I click on a command link in the table.
My issue is if I want to return to search form, clicking on the dynamic task flow link doesn't render the search page.
I have a bean for my dynamic task flow and the taskFlowId variable shows the url of my search page, but the navigation does not happen.
Is there something that needs to be reset for this to work?

Hi Frank,
Sorry about being vague.
I've compiled a little project using the hr sample db that duplicates my issue.
Let me know if you have issues downloading it.
I can provide the project via email if needed.
Change your db connection to whatever you've defined for the hr db. I have mine running on a slave machine.
If you click on "Search", search for an employee and then load the employee details by clicking on the employee id link in the table, the region navigates to the employee details page.
However, if you click on "Search" again, the region does not navigate to the search page, it stays on the employee details page.
I'm hoping it's just a setting in the properties for the task flow or the page fragment, but I can pen some code if needed.

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

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) .

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.

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).

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

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?
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<task-flow-definition id="task-flow-definition">
<task-flow-call id="adfc">

I've tried every conceivable way to navigate from the bounded task flow, to the unbounded task flow, and the only consistent thing I receive is a 404. Is this a security issue?

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.

Can't create an ExecuteWithParams activity in a bounded task flow

I'm trying to replicate the application in the demo, Passing Parameters to a TaskFlow on the URL - http://www.youtube.com/watch?v=3cklxe1qq5I
I created a ViewObject named PagerByLastName which has an iterator with the generated name, PagerByLastName1Iterator
(in Data Controls, a node is created for PagerByLastName , named PagerByLastName1
PagerByLastName1 has query with a parameter and binding variable for the parameter.
Next, I created a bound task flow and tried to drop an ExecuteWithParams from within PagerByLastName1 onto the bounded task flow.
However, in the Edit Action Binding dialog that opens, the Data Collection section is read-only and I'm unable to select a data collection to create
the ExecuteWithParams activity.
A warning message appears as I try to drop ExecuteWithParams -
"WARNING: IteratorNameNotFound--AppModuleDataControl1.PagerByLastName1"
However, the iterator name should be PagerByLastName1Iterator
Known issue? Is there any workaround?

The ViewObject does have both a query and bind variable defined for the parameter in the query.
The query is

I DnD the ExecuteWithParams node to the task flow and the Edit Action Bindings dialog opens, but I cannot select a data collection, the collections are collapsed

Best Practice - Bounded Task Flows, Regions and Nested Application Modules

Using JDev 11.1.1.3; understand that it's generally considered good practice to just have 1 root application module servicing model content / services for each page. In our application, we've used a number of bounded task flows and page fragments deployed as af:region's into pages as either a) views targeted in page-flow navigation, b) tab panel content inside a regular jspx, or c) af:popup / af:dialog content. As it stands, we've not engaged nesting of the application modules for this embedded region content, so these regions are no doubt instantiating new AM's if/when invoked. Should the AM's servicing these embedded regions be deployed nested within the root AM's, and then if so, does this change the way that the jsff / fragment content is actually developed (currently as per any other jspx using the DataControl pallete). Or are the best-practice directives talking about a page as being the design-time / declarative composition of content rather than the run-time aggregation of page + fragments ... in which case the fact that our embedded fragments are not using nested AM's is unlikely to concern.
Thanks,

Probably a better question for the ADF EMG: http://groups.google.com/group/adf-methodology?hl=en

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

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,

And we're back again.... what's a couple months between friends?
So it turns out after testing our app (d@mn, 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.

Call a jsff page in an bounded task flow.

Hi,
Am using jdeveloper 11.1.1.6.0
I have a bounded task flow named welcomeTF.xml which calls another bounded task flow named LeadsTF. The LeadsTF bounded task flow contains 3 jsff pages(named lv.jsff, lv1.jsff, lv2.jsff).
WelcomeTF(Bounded TaskFlow)------------------------------------>LeadsTF(Bounded Task Flow).
When my user runs the jspx page the Welcome page(from WelcomeTF) renders which has 3 buttons (named Button1,Button2,Button3). These 3 buttons should call the LeadsTF Bounded task flow but with different jsff pages.
Button1 -------------------------------> LeadsTF(lv.jsff)
Button2 -------------------------------> LeadsTF(lv1.jsff)
Button3 -------------------------------> LeadsTF(lv2.jsff)
How can i achieve this? Please help me with the samples.
Regards,
Prasad K T.

You can define a TF parameter for the LeadsTF and use this parameter to route the navigation to either lv.jsff, lv1.jsff or lv2.jsff when entering this TF:
Add a TF parameter (e.g. call it "InitialTarget" and map it to #{pageFlowScope.initialTarget})
Add an ADF Router activity as a default activity in LeadsTF
Configure the router activity to navigate to the appropriate JSF fragment depending on the value of #{pageFlowScope.initalTarget}
Make the buttons in the parent TF set different values of the TF parameter when calling the LeadsTF

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

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.

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 =(
