Bounded task from unbounded task

can i call bounded task from unbounded task ?
when i drop n drag bounded task flow definition file into unbounded task flow i am seeing an X mark which saying "An unbounded task flow refer to pages and therefore can't call bounded task flow"
Please suggest?
Thanks

I did same things
below is my unbounded task flow ,i have added button in home.jspx with action is "request" so that on click of button ,my bounded task flow call.
home.jspx -------------(request)-------------------->bounded_task_flow
so when i called home.jspx it is running fine,but when i press button whose action is request ,i am getting same error.
Thanks

Bounded vs. Unbounded task flows

I have read the appropriate doc (Ch 13 in the Fusion Dev Guide for OADF) regarding bounded vs. unbounded task flows. Am still somewhat confused by the differences. For a bounded task flow the doc says: 'Has a single entry point.' When I build a bounded task flow (JDev 11.1.1.0) with multiple views I can enter the task flow at ANY of the jspx pages. This is not what I call a single point of entry.
Please explain what is meant by the above statement as opposed to an unbounded task flow.
THANKS - Casey

Casey,
no you can't. Please have a look at the diagram if it shows a green circle around one of your activities demarking the entry point. Don't confuse running a JSPX page from running a taskflow. Taskflows don't own the pages! Taskflows reference the pages. This means that you can call the JSPX page directly, but its not within the context of a bounded taskflow, but implicitly added to the unbounded taskflow. So you may want to use ADF Security and grant no permissions to JSPX pages to prevent users from directly calling a JSPX page. Bounded taskflows are not a mean to protect pages from access.

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?

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?

Task 1 calling a Task 2. Task 2 home in Task1. Can I do this?

Hi,
I am using JDev11.1.1.2.0 and ADF 11g.
I have 2 task flows. 1 unbounded and another bounded. I am calling the bounded from unbounded task.
The bounded tasks have many screen having same event i.e. "Master page". This master page is in unbounded task. How do I call this back from the bounded task? Better how to work on this?
Thanks in advance.

Hi,
have a look at the parent-action that you find in the Component palette when you the selection to "All pages" with the task flow opened. In your bounded task flow you create a wildcard flow that points to the parent-action element so that you can call it from everywhere in the bounded task flow
See: http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/taskflows_activities.htm#BABEFIBC

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.

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

Hi,
have a bounded task flow which represents the main flow of the application,
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:
10.4.5 404 Not Found
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 ?
regards.

Problems with breadcrumbs in TP4 be bounded and unbounded Task-Flows

Project scope
JDev 11g TP4
jspx - template
jsff - breadcrumbs
jspx - forms (using the template)
bound and unbound task-flow
.) all forms (and template) are in the unbound task-flow (adfc-confi.xml)
.) one form can be called with an parameter from another form - problem solved with an bound task-flow (task-flow-definition.xml) - it works very good
With "Create ADF Menu" (on adfc-confi.xml) the JDev create
root_menu.xml
<control-flow-rule> entries in adf-config.xml
<managed-bean> entrie in adf-config.xml
The code from the breadcrumbs.jsff looks like
<af:breadCrumbs value="#{root_menu}" var="rootMenuNode"
                  id="BreadCrumbs">
    <f:facet name="nodeStamp">
      <af:commandNavigationItem text="#{rootMenuNode.label}"
                                action="#{rootMenuNode.doAction}"
                                icon="#{rootMenuNode.icon}"
                                destination="#{rootMenuNode.destination}"
                                rendered="#{rootMenuNode.rendered}"/>
    </f:facet>
</af:breadCrumbs>
I have now two problems:
1.) by navigation between the pages(in the definition of the unbound task-flow (adfc-confi.xml)) the breadcrumb displayed only the current page but not the history way.
2.) after call the form with an parameter (need bound task-flow (task-folw-definition.xml)) all breadcrumb informations are cleared - nothing is displayed
can anybody help?

Hi,
the generated menu model only works for unbound flows. You can call a bound flow from such a menu, but this doesn't show breadcrumbs within the bound taskflow. For this you need to specify that the bound taskflow creates a breadcrumb model and then it will only show what is within. Have a look at the taskflow section in the developer guide.

How to filter View Objects on Main Page - Unbounded Task Flow

Hi All,
Version: 11.1.1.4
I have a scenario where I am trying to filter the Employee information by EmployeeID and show their related Items. I can do this if I encapsulate Employee and / or Items in bounded task flows and expose their view Criteria in methods that I am setting on the App Module. I could also add the bind variable to the View Object queries. The problem I am having is that I want to display a pop up based on the item they select. My issue is that I can't seem to figure out how to either grab the item row selected and pass it to the pop up (Can't create a control flow from a page fragment to a page - which as far as I can understand the pop up in the task flow has to be a page and not a page fragment) or drop the employee view object and item view object on the main page and have them be filtered.
So basically two issues:
1. If I use the Employee and Item bounded task flows and place them as regions on the main page then I am having difficulties passing the row selection (item selected) and pass it to my pop up window (another task flow).
2. If I place the employee and item view objects on my main page the original methods I am using to filter the data are not getting called at all. I have tried placing them in the adf-config task flow prior to my main page view and going into my main page page def and adding them as method calls in the binding.
I am sure I am doing something wrong or maybe even creating an invalid approach, but I should be able to filter my employee and item data on load within my unbounded task flow or use the data within my bounded task flows and generate a popup with data I am collecting from my item row.
As always greatly appreciate the feedback....still really ignorant with ADF.
--S

I figured out the issue Shay. I didn't have my pageFlowScope value set on the task-flow-call. So I had the parameter name and value set on the input of my downstream bounded task flow, but when I add the control to call the task flow I didn't have the task-flow call value set. That piece was not intuitive to me. It makes sense that it would have to know how to pass the value.....just wasn't sure where it should be set.

Modify unbounded task flow for login process

I wonder if I can use the unbounded task flow for login process. I have a login page, a home page and a change password page. As per the requirements, I need to show the login page first, if user password is expired, I need to show change password page, after user save the new password, I show the home page. If user password is not expired, then we go to home page directly.
I have modified the unbound task flow adfc-config.xml. I have created a method call, which references a method in my managed bean to check the redirect page. I have created a router, which would go to change password page or the home page based on different outcomes. But the problem is, every time when I run the application, it always goes to the home page directly, even when the user password is already expired. I have set up break point at the checking redirect page method in my managed bean, looks like it never got called.
Did I miss any steps here? Please advise. Thanks.

A method is not a runnable object in your pageflow - so you can't start from it.
You need to start from a page when your run your project.
One option - convert your flow to be a bounded flow with the method as a default URL and then run it.

Secure page unbounded task flow

i need to secure access to jspx pages in a unbounded task flow. what is the best way to achieve this using jdev 11.1.15 ?
as of now any user is able to access any jspx pages by typing a URL after logging in.
Edited by: 963798 on Dec 17, 2012 4:06 AM

You can't stop users from accessing pages defined in the unbounded taskflow as, by design, all pages in an unbounded taskflow are accessible from anywhere in you application. So all you can do is add the pages you want to secure to bounded taskflows, add resource grants to the taskflow (remove them for the actual pages/jspx), configure the taskflows so they cannot be invoked from a url and add the taskflows to the unbounded taskflow (just drag and drop them to the unbounded taskflow or change you view activity to a taskflow call). Hope this helps.

Including the unbounded task flow pages to a template content region

I have a template with a left and content region.All the pages are linked through an unbounded task flow. On clicking on the left menu options I need to include the unbounded task flow views to the content region. Is there any way to accomplish this ?
jsp:include is a way to do this ?. I need to change the pageview onclicking on the left menu .It should work like an iframe in html.That means somehow I need to invoke http://127.0.0.1:7101/RMEWebApps-PlsSuiteWeb-context-root/faces/test through the jsp include or using some other mechanism in the content region
How can I do this ?
Thanks

This is an integration project. We do have an application already using unbounded task flow.We have some other projects as well using regions and bounded task flows. We need to create a frame work so that we can navigate to different projects from the main project.
What should be the best design approach for integration
1) Import ADF lib jar files of other projects to main project.Create an unbounded task flow linking all unbounded task flows and create a menu out of that which will link to different projects in the main project
2) Convert all unbounded task flows to bounded task flows and link the pages.Import ADF lib jar files of other projects to main project.Create a region in main project and dynamically change the region by refreshing it.

Unbounded task flow with pageflowscope

Hi,
In my application, I have create unbounded task flow for each menu. For each menu task flow I have created a pageFlowscope bean. When I try to use this bean in any request scoped bean called from within the UTF, I get the pageFlowSCoped bean instance as null.
PageFlowScoped bean declared in UTF:
<managed-bean id="__3">
<managed-bean-name>uiManager</managed-bean-name>
<managed-bean-class>oracle.test.UIManager</managed-bean-class>
<managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>
This UTF has a jsf page which consists of few BTF’s. In one of these BTF, I have a fragment page for which I have used request scoped bean. In this bean, the instance of uiManager is coming as null.
BTF where requestScoped bean declared:
<managed-bean id="__1">
<managed-bean-name>EmployeePage</managed-bean-name>
<managed-bean-class>oracle.test.employee.EmployeePage </managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property id="__13">
<property-name> uiManager </property-name>
<property-class> oracle.test.UIManager </property-class>
<value>#{pageFlowScope. uiManager }</value>
</managed-property>
Inside EmployeePage.java:
private UIManager uiManager;
public void setUiManager(UIManager uiManager) {
this.uiManager = uiManager;
public UIManager getUiManager() {
return uiManager;
Can anyone please let me know what is wrong with this?
Thanks in advance.

Hi,
This UTF has a jsf page which consists of few BTF’s. In one of these BTF, I have a fragment page for which I have used request scoped bean. In this bean, the instance of uiManager is coming as null.Yes it will because each taskflow has its own flow. So when you refer pageFlowScope inside BTF the framework will look in its own flow i.e in BTF to find uiManager hence you get null. Which is present in page flow,
So in that case what you can do is have a inputParameter in BTF that has variable called uiManager of type UIManager.
when dragging and dropping it in page of UTF specify the inputparameter as #{pageFlowScope.uiManager} what you have mentioned as
<managed-bean id="__3">
<managed-bean-name>uiManager</managed-bean-name>
<managed-bean-class>oracle.test.UIManager</managed-bean-class>
<managed-bean-scope>pageFlow</managed-bean-scope>
</managed-bean>And thus you can access the uiManager the way you except.

How can I move a task from a Summary Task to another Summary Task in the same task list?

Hey, I tried to move tasks through the SP UI from one Summary Task to other in the same task list, but I didn't find possibility for it.
Then I spent time to learn the SP Client Object Model and now I can read tasks form the list. I see every task has a "FileRef" and a "FileDirRef" field. If I think right these fields show the relation between list elements for example between
a Task and a Summary Task elements.
I changed these fields' values and I tried to Update the ListItem but I got this error message: "Invalid data has been used to update the list item. The field you are trying to update may be read only."
I really need to move tasks what were created below a wrong Summary Task so please explain a method or pattern how I can do this. (I can create a new Task below to any Summary Task and I can set field values but I hope there is a way to really move tasks (I
mean I should change the right field values somehow.).
I can reach the Task List both on the server and client side so I'm very interested in every solution. PowerShell solution is also good for me.
I'm using SharePoint 2010 SP2.
Thank you for your answer and your time. :)
Csaba Marosi

Hi,
According to your post, my understanding is that you want to move a task from one summary task to another in the same task list.
We can do it like this:
We can create a Gantt View for this task list, then copy your tasks inside a summary task, then navigate back to the other summary and paste, then go back to original and delete.
Here is another way for your reference:

Send Email from approval task form

In my reusable workflow, I have added an approval action. Everything works perfectly. What I want is - When approver comes to approval form, he should be able to send notification email to the initiator (From that form) that he has started working on that document.
What I have tried - I have added a button clicking on which will submit the form to initiator.
But it fails. possible reason - when I create a data connection in workflow's infopath form to submit form as email, I am getting following warning
"Domain trust form templates cannot be sent as email attachments. to fix this problem, modify the form option to change the security level of form template to restricted".
I also tried to update status field and wait for it to changes in workflow and send an email from sp designer workflow. it didn't work.
Please help or suggest any other possible way to achieve this functionality (Send Email from approval task form to initiator).

Hi mry,
I could reproduce on my SharePoint 2013 on-premise based on your another
post.
Based on the the following article, SharePoint workflow cannot use the InfoPath form in restricted mode which doesn't allow the data connection, but as your image warning message shows sending InfoPath form as mail attachments will need restricted level.
http://msdn.microsoft.com/en-us/library/office/ee526352.aspx
You can consider to send a mail to initiator in "Whe a Task Completes" step when you click button approved/rejected, and construct the current task form link format as follow,
