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

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?

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.

Why do we want use 'Data Flow Task' to 'Data Flow Tast' in Control Flow?

I found an example in my company's SSIS package folders. In Control Flow, it has one data flow connected to the other. Both of them are importing data from flat file and then exported to database. I think these two are kind of at the same level and cannot
see any reasons to conncect them together.
Thanks & Happy Thxgiving,
Gavin

Hi Gavin,
Just as Arthur said, if there is no relationship between those two data flow tasks, we don’t have to connect them together. If they connect together, maybe there are some relationship between them.
According to your description, both of the data flow tasks are importing data from flat file and then exported to database. It seems that there is no direct relationship between them. Another possibility is that there is a precedence constraint between them.
The precedence constraint can be based on a combination of the first execution results and the evaluation of expressions. We can check the issue by double-check the connection string between them.
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,

How to use a managed bean in a bounded task flow without definig it in adfc-config

Dear all
I create a bounded task flow without page fragments (the pages are jspx), i created a jspx page with a button that its action has bounded to a managed bean function.
i defined the managed bean on the corresponding bounded task flow, but it does not work.
But there is no problem when i define the managed bean in adfc-config.xml.
can anybody help me with this problem.
is it possible to use jspx page with backing bean in bounded task flows, without defining the beans on adfc-config?
Thank you very much

Dear Timo
I use jDev 11.1.1.6 and the scope is Request.Although when i use task flow page fragment and create jsff pages, there is no problem.

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?
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

How to pass parameter through URL to bounded task flow with page fragment

I want to pass parameter to Bounded Task Flow With Page Fragment trough URL
as I start this taks flow with router and according to this Param I will rout the user.
I added input param to taks flow named direction and make the task flow called URL invoke url-invoke-allowed
<input-parameter-definition id="__41">
      <name id="__42">direction</name>
      <value>#{pageFlowScope.direction}</value>
      <class>java.lang.String</class>
    </input-parameter-definition>but I don't know how to add this to the JSPX that I will add the bounded task flow Inside.
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

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

Reuse Task flows without Page fragment

Hello,
I ve seen some examples with task flows being resued inside regions and using page fragments.
However , my requirement is little different and would like some inputs on this.
I have an authentication module to be used in different ADF applications.
I have a login page(not a page fragment) and a router and task flow return activity in the resuable bounded task flow.
We are having a managed bean to check authentication and we have a page flow scope variable which marks success or failure and hands it over to router which inturn routes to task flow return if successful, else routs it back to login page if failure.
When i use this BTF in a consuming task flow(BTF) and add the module as an ADF library, everything is fine except it is not lauching a welcome page upon success and just stays on the same login page.
I have the ADF security on with the redirect page given upon successful authentication as the welcome page.
The welcome page is in the consuming application and not part of the authentication module itself.
In the consuming task flow, i have a control case from the Authentication task flow call activity to the welcome page and the control case rightly given success as outcome automatically bcos of task flow return in the consumed task flow.
Any input to launch the welcome page upon successful authentication is greatly appreciated.

Hi,
you cannot authenticate users in a bounded task flow and expect to redirect you successfully. The redirect only happens if authentication is handled by the ADF Security authentication servlet redirecting the call. So your bounde task flow needs to return an outcome and your consuming application should have a wild card navigation case defined that then redirects to the welcome page

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?

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

Drag and drop a bounded task flow in a jspx page

Hi!!
I am using jdeveloper 11.1.2.1 I had created a Bounded task flow which contains a jsff
page.While i am trying to drag and drop this Bounded task flow as a region in jspx page
am getting the error as
Cannot create a region from a taskflow containing facelets fragements in a
jspx page.

see the difference between JSP XML documents and Facelets-
http://oracleadf-java.blogspot.in/2013/05/beauty-of-adf-taskflow-difference-bw.html
both are different view technology.
Always Remember if
fragment is .jsff (JspXML type)-- main page must be of JSP XML type (.jspx )
fragment is .jsff (Facelets typee)-- main page must be of Facelets type (.JSF)

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

How to add many bounded task flow just on one only .jspx page?

Dear all
I will explain you what I do and What I want to do.
I created one jsf page template called "baseTemplate". It contains only one panelSpliter with horizontal layout . In the first face I created 10 commandLinks as a menu. the second facet contains the facet ref.
My task is now to create 10 task flows.
What i do is:
1- create bounded task flow name it "taskFlow1" and add all the views and page navigations that I want.
2- double click the views and create them as page fragment and design the layout.
3- create .jspx page name "task1.jpx" based on "baseTemplate".
4- dragging and dropping "taskFlow1" into "task1.jspx" as a region
5- repeating steps from 1 to 4 with "task2.jspx" till "task10.jspx"
in this way i created 10 "jspx" pages for each task flow
What i want to do is:
I want to create just one and only one ".jspx" page and drag all task flows on it. And when clicking on any command link from the menu , the corresponding task flow is invoke.
Is this a way to do this.
Thank you in advance.

of course, there is.simply in the unbounded Task flow drag your task flow as task flow call and specify the outcome, and make the action of your command link
the outcome you specify, of course you will navigate to the default activity of the bounded task flow also you could open your task flow as lightweight dialog
as frank do in his example

Trains and Fragment Based bounded task flows

The Problem:
I am trying to create a bounded task flow based on fragments using a train. I have created the train and it is showing up on my page. Unfortunately, when I click next on the af:trainButtonBar the UI does not update. If I navigate off the page and come back to the page containing the train the UI is on the next task in the task flow and the train is updated but it is not happening through partial page rendering. Does anyone have an idea why the UI is not updating? Here are some of the file contents:

Master-detail table where detail is in a bounded task flow

Dear all,
Iam pretty much new to ADF 11g. I have the following question.
I have a search form(using af:query) created from the View Criteria of a view. The search results are displayed in a master-detail table, since my view has the following form in the data control:
MasterView ->DetailView
I would like that the detail table be part of a page fragment of a region of a bounded task flow. And of course, the detail table should be refreshed every time another row is selected in the master table.
Is this feasible? Because I find difficulties in the following areas:
1. How to pass a parameter to the bounded task flow that will display the detail table?
(I suppose that I will need to build a new view to display the DetailView. In the WHERE clause I will have to pass the id of the row clicked in the master table.
2.How passing the variable to the bounded task flow of the detail table be implemented when clicking the row of the master table? In similar examples I have seen, e.g. in the ADF Code Corner, there is always a submit button that sets a pageFlowScope variable.
Is my approach feasible or it needs a lot of ADF twisting?
Edited by: dimitris74 on Sep 12, 2011 6:20 AM

Hi,
If you have two different regions in your page for master and details and you want to refresh the child table based on your master row selection then you can use the contextual actions. Raise an event whenever you select a row and send your master-table id as the payload. Have a handler method at the detail page and execute some logic to get the rows for the selected master record.
I hope it helps you.
Thanks,
Lakshman
