Invoke task flow from backing bean?

Hi,
Is there a way to invoke task flow from a backing bean? If yes, how?
Thanks in advance

Thanks Frank. I am not an expert with ADF so please bear with me if my questions doesn't make sense. Basically what I am trying to achieve is this.
I have a taskflow and I am currently in a ui page which displays a page fragment inside this task flow. In this page, on click of a button, I need to call another task flow and show it in a adf popup. Is this the case referred in the pdf document that you pointed out?
Thanks

Can we call a task-flow from a bean in adf?

Sir,
Can we call a task-flow from a bean in adf?
Regards

you can do this using taskflow call activity
check - Oracle ADF World: ADF Task Flow Call Activities
http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_activities.htm#ADFFD21945
you can pass input parameter map and dynamic taskflow reference from managed bean
check -https://blogs.oracle.com/DavidGiammona/entry/dynamically_assign_task_flow_c
Or if you want to use dynamic region to swich between taskflows

Button Actions are not working -invoking task flow from other project regio

Hi
I have a project using a mani.jspx file having a regions and the region is updated with different views based on a router condition in my bounded task flow. Everything working fine with in the project. I have a seperate project in my application having an index.jspx and region in it. I created the ADF lib jar file of the first project and imported to this project. I could invoke the task flow in the first project to the region in the index.jspx file in the seconed project.But none of the action managed bean method attached to the buttons in this view are working.The methods are not getting called on clicking on button and no error in the backend console of Integrated weblogic server.Any body can help what could be the issue ?
Thanks
Suneesh

The issue that is happening when I refreshed the region with task flow from the project I imported.If I load the taskflow from the imported project on first time rendering all my managed bean actions are executing but if I load a different flow initially and change the taskflow Id imported from other project none of the managed actions are working.
Thanks

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

Populating a parameter of a task flow from a different task flow

I have created a BPM process, where two human activities are there. Two human task consist of two task flows. I have inserted some data into table using store procedure from first task flow and passed the id (unique id of table) through BPM process data object into the second task flow. Now I want to start the second task flow with execute with Parameter attribute(where customized query been written on the view object to find details from table) and find the inserted row in the second task flow using the id and show it in a jspx page.
Please help.

You can pass managed bean as input parameter to your BTF, or you can use contextual events, or ...
Maybe I didn't understood you description correctly, but if you use only one dynamic region, then you can't call BTF2 from BTF1.
If you have two regions, one displays BTF1 and second displays BTF2, then this is possible.

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 we call two task flow from another task flow

Hi everyone,
i have a issue. I have a tab(p1),under that tab i have created two tab(p1 and p2).i have to create task flow for p1 and p2 .In both ,p1 and p2, i am doing some operations. then i have to call both the task flow under another task flow(p1).what should be the steps i have to take to do that.
My version is 11.1.1.6
please respond as soon as possible.
Thanks in advance....

hi
sorry to say this
i have not much time to play 20-20 chat. please elaborate you usecase. you can get you answer within a post
but we will use router when we have some condition.if you are using router. you should use some "condition" what is that?
but in both the child tab,i just have to fill the form.ok. i hope that you are using af:table in parent TF. in child tab you are using af:form
before commiting or at the time if commiting you should get the data's in af:form. if am right means you should have association/viewlink between those eo's/vo's
if you have means while commiting the parent table iterate over the rows show in child tab - af:form
it will show the both the child panel.go to panettab render poerpty rendered say as condition {yourparenttableiteratoecount ge 0 ? true : false}
or else as you said, make router condition {yourparenttableiteratoecount ge 0} show the child TF.
from the answer you may understood.(just a hope)

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 =(

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

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

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