Is it possible to call a task flow present in 1 ADF Mobile Application to another ADF Mobile Application?

In ADF Mobile, I want to call a task flow present in application1 to a different application2 on click of a button. Is it possible?

Hi,
This is my code to call the package.
String amDef = "model.service.DAFService";
String config = "DAFServiceLocal";
ApplicationModule am =
Configuration.createRootApplicationModule(amDef, config);
     CallableStatement cstmt = null;
     String stmt = "begin call CP_DAF_PKG.DAF_PROCESS(?,?,?,?,?,?,?,?,?); end; ";
     cstmt = getDBTransaction().createCallableStatement(stmt,0);
But in this case, I am getting
oracle.jbo.InvalidOwnerException: JBO-25301: Application module is not a root app module but has no parent
I understand the reason for this error. I need to call the
createcallableStatement from the application module that I have above.
Something like am. (call the package)
But not sure about any method which does that..
Please let me know if you know the way to solve it.
Thanks,
Venki

Calling bounded task flows imported as ADF libraries

Hello,
I have a main application referencing many bounded task flows included in ADF libraries.
Is there a way to make the application not throwing exceptions if one of these libraries including the called task flow is not found?
The first question is how to catch the exception "Caused by: oracle.adf.controller.ControllerException: ADFC-02001"
The second problem is that once an exception is thrown , the only way to make the application work again with that task flow is to redeploy the whole application with the missing library in the proper place.
It seems it is not possible to just add the library at run-time.
Redoplying an application also seems to invalidate all the current open sessions.
Could you give me suggestions or best practice on making the main application more indipendent from the libraries?
Thanks.

Hello Frank,
It seems there's no way to catch the exception thrown when dinamically calling a bounded task flow in a (missing) library. In facts, I added the single page of the main application as default exception handler activity. I also tried to catch ALL exceptions in the Launcher class below, but I had no luck at all. Task flows are called dinamically from this common piece of code (appropriate for the UI Shell template):
try {
if (newTab) {
TabContext.getCurrentInstance().addTab(title, taskflowId);
} else {
TabContext.getCurrentInstance().addOrSelectTab(title,
taskflowId);
} catch (TabContext.TabOverflowException toe) {
toe.handleDefault();
} catch (ControllerException ce) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (RuntimeException re) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (Exception e) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
I also tried to call the task flow in a remote application, but TabContext.getCurrentInstance().addTab(title, taskflowId) expects the taskflowid to be part of the main application, not of the remote app, since addTab() always add a "/" before the taskflowid String passes as parameter.
So again my question: is there a way to profit by the dynamic features coming along with the UI Shell template, where task flows can be really referenced and called each time at run-time, no matter if libraries containing these task flows are present or not when deploying the caller application?
I also repeat that from the tests I have done it looks like I can deploy the caller application without the referenced ADF libraries in their place (containing taskflows that should be called at run-time on user actions), but the problem in this case is that after that moment there's no way to fix the problem by just adding the missing library, that is you cannot place the library where it is expected to be and expect the caller to work after next call; this will just not work until next deploy of the calling application when libraries are in place . We also don't want completely separate web applications. We need task flows integration with the chance to modify and deploy these taskflows as ADF libraries at run time, separately from the caller of the taskflow, without needing to restart/deploy the caller application everytime a libraries changes or a missing library is added.

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

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)

How to call the task flow one region from another region?

I have page with 3 regions (column wise) named as start, center, end.
currently I having task flow for middle(i.e, center) region which have panelCollection to perform view, create, & delete functions.
Task flow:-
From(action)To
View(create)Create
Create(Done)Execute (Execute is a method call)
Execute(*)View
View(self)Execute
By press create button on Center page, task flow takes to the Create page(in Centre region) but all other regions(start, end) remains same.
I have a usecase where we have a commandLink on Start region to show the View page on Center region. but it is not able to achieve when we move to Create/Edit page.
Plz help me out to built the same.
Thanq

Hi!
First, I'm not sure that your page layout is adequate. The regions are not intended to be navigated from outside. Yet, they can send navigation action to the container (page on which the region is placed) through Parent Action taskflow element. Also, you can investigate Contextual Events that can be raised by region, but I'm also not sure that this can be easily used for cross-region navigation.
I would suggest you to reconsider you page layout. You can use dynamic regions (which are populated by taskflow based on menu selection or click on actionLink or s button). This way, in the Start facet you place a navigation menu (links), which are connected with dynamic region in Center. If you want to reuse a navigation links (in Start), you can put all this in page template and reuse it over and over again.

Hi Arun,
In my task flow i am calling a jspx page as a popup,
through my jspx page I can do all these operations,
but the problem is when I am trying to call a method written in the Backing bean of that page, at that time only the method is not getting the bindings.
Create insert operation is there in the bindings....

ADF Task Flows

Hi Experts, would like to ask if it's possible to CALL a task flow from another task flow? or is it possible to merge 2 or more task flows.
Just thinking if it's possible to re-use a taskflow or a page since we have a lot of common pages..
Thanks...

And to be clear, note the use of the words "bounded task flow". You need to clearly understand the difference between "unbounded task flows" and "bounded task flows". "Task flow" is the generic name for both types, and from your original post it's not clear which type you've used.

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.

ADF Task Flow: Using Task Flow Call as Application Entry Point

In our product we have a task flow structure very similar to the Fusion Order Demo application, but we are having serious trouble reproducing the documented functionality of ADF Task Flows.
Specifically, we cannot use a task flow call as an entry point for our application, which is very important for us to achieve.
The [Developer s Guide|http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/taskflows.htm#ADFFD1634] states about the [demo application|http://www.oracle.com/technology/products/jdev/samples/fod/index.html] :
"A Fusion web application always contains an ADF unbounded task flow, which contains the entry point or points to the application. Figure 14-3 displays the diagram for the unbounded task flow from the Fusion Order Demo Application. This task flow contains the Home, *MyOrders*, *checkout*, registerUser, and updateUserInfo *view activities, which are all entry points to the application*."
"The checkout-task-flow activity in Figure 14-3 is a call to an ADF bounded task flow."
When we run the Fusion Demo Application, we are only able to use home, updateUserInfo and register as entry points.
We cannot enter the application through any of the task flow call activities (MyOrders and checkout) as the documentation suggests.
What are the reasons for this and how do we fix it, so we can use task flow call activities as application entry points?
Thanks.
Edited by: Rune Glerup on Oct 9, 2009 2:51 AM
The forum did not display the link to "Developer's Guide" because the link contained the single quote char '. Single quote char removed.

Is what you mention here the case in the Fusion Order Demo application?
If the task flow call activities cannot be used as entry points, why is it stated in the documentation?
How do we solve this, so that the task flow call activities (including parameter bindings) can be used as entry points, like the documentation suggests?

Is it possible to call a task flow present in 1 ADF Mobile Application to another ADF Mobile Application?
