11g TP2 ADF Task Flows and Transaction Management

I'm wondering how ADF Task Flow Transaction Management works vis-a-vis database sessions and using stored procedure calls in an environment with connection pooling. I haven't written the code yet but am looking for a better understanding of how it works before I try.
Example:
I create a bounded adf task flow. I set the "transaction" property to "new-transaction" and the "data control scope" to "isolated".
As the task flow is running, the user clicks buttons that navigate from page to page in the flow. Each button click posts the page back to the app server. On the app server a backing bean method in each page calls a stored procedure in a database package to modify some values in one or more tables in the database. The procedure does not commit these changes.
Each time a backing bean makes a stored procedure call will it be in the same database session? Or will connection pooling possibly return a different database connection and therefore a different database session?
If the transaction management feature of the adf task flows guarantees me that I will always be in the same database session then I don't have to write any extra code to make this work. Will it do that or not?

I don't know if it is documented in the adf documentation currently available for 11g TP2 but what you ask for is a normal transaction management with connection pooling and i can't imagine it is not implemented in ADF BC layer like it is in JPA or other persistence layer.
A transaction will always be executed in the same session. Normally your web session will stay in the same session even you start more than one transaction. You don't have to write any code to manage the session pooling. It is a good practices to customize it at the persistence layer during installation depending on your infrastructure.
Take a look into Fusion Developer Guide ... i'm sure you will find some better explanations about this.

ADF task-flow and transactions

Hi All,
I have created a web application using ADF and JDeveloper 11.1.1.4. The ADF web application has two pages 'Search' and 'Edit'. The 'Search' and 'Edit' are page fragments. I have two bounded task flows 'search-flow.xml and 'edit-flow.xml'. The search and edit functionality has been created as dynamic regions by dragging the task-flows onto the JSF page.
The bounded search-flow.xml has page flow from search ----> edit(Parent Action component)
The bounded edit-flow.xml has page flow as *-->edit----> search(Parent Action component)
User comes from login page to the search page. On search page users can choose to search for records and edit individual searched records or create a new record using 'CreateInsert' button. Either way users end up on the edit page.
On the edit page, users see a form to fill or modify. They have the choice to navigate back to search page using 'Search' button or commit changed record using 'Save' button or create new record using 'Create' button
The application is functioning 90% as expected, only problem is the transaction management part if the user does not care to save each time the edit is made.
Say for instance, on search page user press ' CreateInsert' button which takes the user to edit page and then without saving the new record user presses 'Search' button which takes the user to search page and so repeated goes back and forth cycle.
In such cases the transaction never ends, The primary key for each new record is retrieved from the DB sequence only on persisting to database. A place holder like negative integer is used for the primary key temporarily till new record is persisted to database.
As per best practices, I am using the checkUncommittedDatabehavior which prompts the user when navigation is done away from the edit page i.e. without saving on pressing the 'Search' button on edit page. User can choose 'OK' or 'Cancel' which comes bundled with the ADF checkUncommittedDatabehavior property. Even after selecting OK the new record does not seems to be rollbacked (Issue 1).
eg:, if the user performs the cycle(i.e navigating between search and edit pages without commit/save) 'n' times, new entity records are created with primary keys -1, -2, -3, -4 ........ so forth. As I said earlier a proper sequence number for the primary key is assigned only if a record is persisted to the database.
Now on the 'n+1' cycle the user fills the records and clicks commit, it comes up with a error 'primary keys with nulls from previous uncommitted record (i.e; 1,2,3, .....n) creation.
I guess the transaction management is not happening correctly and not completing during these cycles (1, 2...n) Note: I am not using 'Task Return' components in my bounded ADF task flows, just commit operation 'Save' button in edit page and checkUncommittedDatabehavior.
Also, in search-flow.xml I have following configured under 'Behavior' tab Transaction ---> No Controller transaction and ' Share data controls with calling task flow checked
in edit-flow.xml, these configurations are in place under 'Behavior' tab Transaction ---> Always begin new transaction and ' Share data controls with calling task flow checked and Critical checked and 'task flow rentry' as reentry-outcome dependant.

Hi Frank,
I checked the DB sequence is setup correctly. I have also modified the problem description above for better understanding.
2. When users press OK, navigate to a commit method activity (just drag and drop the commit operation).
-- When user presses OK, I need to rollback instead of commit to make users lose the unsaved work and controller should navigate to the search page. Here, the message panel with Cancel and OK is shown automatically with the <af:checkUncommittedDataBehavior/> property, I thought the framework will do the rollback for me. If I need to do rollback manually, how to do it, because I cannot see the JSF related source code for the <af:checkUncommittedDataBehavior/> dialog box. Please suggest what to do
3. If they press cancel, have the return activity rolling back to the save point taken when the user entered the bounded task flow (edit task flow)
-- If they press cancel, user stays on the same page, so I will leave future action to the user. This bit is working fine in my app.
Thanks

What is difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
Best regards!

Creation an ADF Task Flow Based on a Human Task

Hello!
While creating ADF Task Flow Based on a Human Task, I can't bind New TaskFlow to task, which I choose in Dialog.
Details:
I Have:
BPM Project with PackageCreation.task
ADF Project in Same Application
I do:
1. in Application Navigator right click on ADF Project -> New -> Web Tier -> JSF -> ADF Task Flow Based on a Human Task
in creation Dialog I choose PackageCreation.task and Don't change name of New TaskFlow (automatically JDeveloper set this name to PackageCreation_TaskFlow)
I have After that:
new ADF Task Flow and my old PackageCreation.task.
Question:
Why my Task don't bind to created ADF task Flow based on it?
I think, that while creating ADF Task Flow Based on a Human Task it has to change my task, writing some thing like This (inside xml):
<taskFlowFileLocation>file:/D:/JDeveloper/mywork/SalesQuoteLab/EnterQuoteUILab/public_html/WEB-INF/EnterQuoteDetails_TaskFlow.xml</taskFlowFileLocation>
That xml element is creating in xml of *.task, while making auto-generation form for human task in BPM Project.

Juan C,
I use JDeveloper 11g Release 1.
May be I didn't explained my question correctly.
taskdetails1 is creating, and in Data Controls I have objects of my BPM Human Task Payload.
But in that file "PackageCreation.task" in source I can't find any link to instantly created TaskFlow.xml in my UI project.
So, I have
NEW project "PackageCreationUI" with PackageCreation_TaskFlow.xml in it (and TaskDetails1 file too).
AND Did't Changed PackageCreation.task in BPM Project.
If I use *"BPM form creation wizard"*, after creating project and TaskFlow in it I see Changes in PackageCreation.task in BPM Project, something like that:
<taskFlowFileLocation>file:/C:/JDeveloper/mywork/testApp/PackageCreationUI/public_html/WEB-INF/PackageCreation_TaskFlow.xml</taskFlowFileLocation>

How to get the logged in userId value in adf task flow

Hi,
I have created an adf task flow and deployed the same in application as an adf library.
Now I need to get the Logged in User ID value in the adf task flow which I created.
Based on this userid I need to run query to fetch the data related to the user from the database.
Please help/guide me to solve this issue.

3 different ways to retrieve the username (not sure what you mean by user ID) :
http://mahmoudoracle.blogspot.be/2012/06/adf-get-current-logged-user-name.html#.USI_c-h8zIo
Also provide your JDev version.
Basicly, you should use the groovy expression in a view criteria (it's the fastest and easiest way) and call that view criteria whenever you need it.
That's if you are using ADF BC of course.

Get the id or namespace of container of ADF Task flow

Hi,
I have an ADF Task flow and I put it inside either a region in a jspx page or portlet page. And I want to refer to the component in the adf page fragment in javascript by its id.
How do I dynamically detect the id of the container of the ADF task flow?
For portlet, I know there might be renderResponse.getNameSpace(). But I can't find way to do with jspx page. Should it be (HttpServletRequest)FacesContext.getCurrentInstance().getRequest().getAttribute("Some attribute name? ");
Any one has done it?
Thanks a lot.

How to deploy a new ADF task flow in OIM 11g R2

Hi,
I have created a new ADF task flow.
Now I need to deploy the same in OIM 11g R2, so that when I click on a link it will call my new ADF task flow.
Please help me in identifying the steps required to deploy the adf task flow.
Thanks

Hi Durga,
Thanks for sharing the post. I think I am facing the same issue which you were facing.
I have already done these steps but still not able to get my custom page on click of a link which I created in OIM self service page :
1. I have created the adflibHomepagePortletsUI.jar as an adf library using Jdeveloper and copied it to oracle.iam.ui.custom-dev-starter-pack.war --> WEB-INF/lib folder after unpacking it.
2. have updated the custom-catalog.xml file inside oracle/adf/rc/metadata folder with the below lines :
<folder name="Sample Folder" id="sampleFolder">
<contents>
<resource id="helloWorld" name="Hello World"
description="Hello World Taskflow Reference"
repository="application.classpath"
path="adflibHomepagePortletsUI.jar/ADF_TaskFlow/WEB-INF+oracle+iam+ui+sample+homepage+tfs+hello-world-tf.xml#hello-world-tf">
<attributes>
<attribute value="coreDefault" attributeId="attr.background" isKey="false"/>
</attributes>
</resource>
</contents>
</folder>
3. repacked the war file and copied it in OIM_HOME/server/apps directory
4. Restarted the OIM server.
5. entered the following lines in jazn-data.xml present in user_projects\domains\idmdomain\servers\oim_server1\tmp\_WL_user\oracle.iam.console.identity.self-service.ear_V2.0\6bddg\META-INF\jazn-data.xml

<name>/WEB-INF/oracle/iam/ui/sample/homepage/tfs/hello-world-tf.xml#hello-world-tf</name>
<actions>view</actions>
</permission>
5. Login to self service console.
6. Click on the custom link who's actionListener is pointing to bean which is launching the taskflow created in the above steps.
7. On Click of the link a new tab gets open with blank page.
Please help me in knowing the step which I am missing in order to solve this issue.
Many thanks once again.

Single adf task flow portlet with multiple pages and paramter from url

Hi ,
I have made a adf task flow portlet with a parameter.
I have made a portal applcation and added multiple pages . in each of the page I am consuming that portlet through wsrp2.
I have mapped the task flow parameter in page bindings of the pages with #{param.code}. where code is the get parameter.
I have edited navigatinoal template so that when i click the pages , code parameter also get added in the url.
issue
When I run the applcation and visits first page with get parameter i get the right result. but when i click the on the other page which has some other value for the same get parameter , it doesnt display the value. But the other page shows me correct value if I go this page first but the later page doesnt display any value.
thanks

ADF Task Flow: Browse and Edit pages

Hi,
My application includes two pages, a Browse page and an Edit page. The Browse page provides the list of departments (read-only table) and allows you to select a department from the list to edit the department details (form).
How can I develop this common scenario using ADF task flows? Important - I need to display Browse and Edit on two different jsf pages.
Thanks, Al

It should be pretty easy.
1) Create your browse and edit page
2) drop them onto a task flow
3) Connect the pages with navigation cases.
4) Set the ACTION property of a button on the browse page to reference the navigation case that goes to the edit page
5) Hook up the reverse to go back to the browse page
Done!

Why Dev Guide says "create a separate project for each ADF task flow ..."

Hi,
We have a BPM process application which is having a few human tasks. The form for each of the human tasks is similar. We’d like to be able to share some page fragments or code between them and create single web application to handle all the human tasks for this BPM process application. Then I found the following in the Oracle document “Developer’s Guide for Oracle SOA Suite 11g Release 1 (11.1.1.4.0)”:
“If the SOA composite contains multiple human tasks, create a separate project for each ADF task flow associated with each human task.”
I wonder if we have to do that and if so, what is the reason.
Do you have any clue? Please help.
Thanks a lot,
Helen

Hi Helen
1. I do not know the reason why they mentioned like separate project for each human task. NO, this is not required and we can have just one UI Project like MyTaskForms and have all the JSPs in this same project for each Human Task.
2. On our side, we have like 10 Human Tasks, all using the same Payload. So we have 10 .task file. For the very first .task file, we used Auto Generate Project and gave project name like OurAppTaskForms. The reason we did this is, so that it adds all the required dependent libraries, tag libs etc properly. For all remaining 9 .tasks file, we did NOT use auto generate. Instead we used standard New -> JSF From Human Task and select one task at a time and follow the steps. These steps are covered in the online documentation. At the end in our BPM App, we have just one UI Project with all the 10 screens.
3. ALSO, all the 10 screens have some common data. This we put in a reusable JSF Fragment page. And associated a custom Managed Bean for this to set and get values from this fragment and also some Actions for some buttons in the JSF. Then we included this JSF in each taskform jsf file, uisng the include tag. We added this include tag, somewhere in the top. So all screens share common jsf fragment page.
4. We can refine the above stuff further. As per above, we still have 10 JSF screens for each one of the 10 .tasks. Ofcourse all these 10 jsf have same common jsf fragment. BUT instead of 10 individual jsf screens, we can have only ONE Jsf screen also. Refer online docs for the details. The challenging part is, since we have only one jsf, there may be some bussiness stuff, validatoin stuff to take care of in custom ValidationCallback Handler classes. Say for Task1, we had to show some buttons, but NOT for Task2. So we had to handle this logic. Also in validation call back, we can always get each Tasks, title also. So we can workaround this issue also. We are in the process of doing this right now. But first 3, we already did and they are working fine.
My personal suggestion is first go with single jsf fragment and include in all tasks jsp files. Any changes to common elements need to make only in one place i.e fragment page.
Thanks

How to use task flow's transaction options with session's user data

Hi.
I have custom extension of ApplicationModuleImpl class:
package test.model
imports...
public class CustomAppModuleImpl extends ApplicationModuleImpl {
    public static final String SESSION_VAR = "MySessionVar";
    public CustomAppModuleImpl() {
        super();
    @Override
    protected void prepareSession(Session session) {
        super.prepareSession(session);
        System.out.println("######## " + this.getClass().getName() + ".prepareSession() called. AM isRoot() = " + isRoot());
        Hashtable userData = session.getUserData();
        if (userData == null) {
            userData = new Hashtable();
        userData.put(SESSION_VAR, "Useless");
    @Override
    protected void create() {
        super.create();
        System.out.println("######## " + this.getClass().getName() + ".prepareSession() called. AM isRoot() = " + isRoot());
}Inside userData I store some useful session-based values (here is just an example ;) ).
Within Model.jpr I defined that every Application Module I create must extends this CustomAppModuleImpl :
   <value n="oracle.jbo.extends.appModule" v="test.model.CustomAppModuleImpl"/>
...I have one AM with one view:
package test.model;
import oracle.jbo.server.ViewObjectImpl;
// ---    File generated by Oracle ADF Business Components Design Time.
// ---    Wed Mar 07 20:22:11 CET 2012
// ---    Custom code may be added to this class.
// ---    Warning: Do not modify method signatures of generated methods.
public class AppModule1Impl extends CustomAppModuleImpl {
     * This is the default constructor (do not remove).
    public AppModule1Impl() {
     * Container's getter for EmployeesView1.
     * @return EmployeesView1
    public ViewObjectImpl getEmployeesView1() {
        return (ViewObjectImpl)findViewObject("EmployeesView1");
}Now I have BTF (bounded task flow, with default properties) and I call that task flow on a button press. With default properties ( Transaction: <No Controller Transaction> ) I get preferred values from session's userData within Entity Object.
Code snippet inside that entity implementation looks like:
        DBTransaction dbt = getDBTransaction();
        System.out.println(getClass().getName() + " entity lives AM: " + dbt.getRootApplicationModule().getClass().getName());
        if (dbt.getSession().getUserData() == null) {
            System.out.println(CustomAppModuleImpl.SESSION_VAR + " -> NULL");
        } else {
            System.out.println(CustomAppModuleImpl.SESSION_VAR + " -> " + dbt.getSession().getUserData().get(CustomAppModuleImpl.SESSION_VAR));
...And as I mentioned output is correct:
test.model.EmployeesImpl entity lives AM: test.model.AppModule1Impl
MySessionVar -> UselessNow the trickiest part. As soon as I change property of called task flow Transaction to something else that +<No Controller Transaction>+, e.g. Always Begin New Transaction, code snippet from task-flow.xml :
    <transaction>
      <new-transaction/>
    </transaction>
..This session stuff begin to act unpredictably. Session's userData is now null. And Output looks like:
test.model.EmployeesImpl entity lives AM: oracle.jbo.server.ApplicationModuleImpl
MySessionVar -> NULLWhy in the world ADF uses oracle.jbo.server.ApplicationModuleImpl instead of test.model.AppModule1Impl or at least my defined test.model.CustomAppModuleImpl ?!?
Is this a bug? Or maybe a feature?

ADF BC alwyas has a transaction opened even if the ADFc setting is No Transaction. So if you explicitly ask for a new transaction I assume that the ADF BC data control creates a new transaction without re-executing your AM initialization codes. Looks as if it uses an internal AM instance for this just to hold the transaction. However, worth filing this as a bug - assuming you reproduced this with a later version of either JDeveloper 11g R1 or R2

This is answered in SOA forum: Re: Why Dev Guide says "create a separate project for each ADF task flow ..."

Is ADF task flows available in jdev 10.1.3.3.

Hie
I was just wondering if ADF task flow is available in jdeveloper 10g? if yes then how can i use it?
Vik

Vik,
transactions are handled in the current version as well. In JDeveloper 11 however you can add an isolated transaction context. In fact the use of page regions and page fragments is unique in JDeveloper 11 (though we had regions in JDeveloper 10.1.3 as well, but not supported).
You can work with subviews in JSF to include other parts of a screen, but this is not the same as using Jeveloper 11 taskflows. So I guess the answer is no you need to have JDeveloper 11

Apart from these, I have Model and View Controller projects in the application. If I create the ADF task flow based on a Human task in another sample application, it works fine. Only in this application, it does not work. Not sure what this error is. Any ideas?
Thanks,
Manoj

What I suggest is go into EM and undeploy this composite and all versions. (Only if you don't want the existing ones). Then redeploy your process. This will avoid the version conflict and create a new version. 1.0. Then the next time you try and deploy you need to either specify a new version or check the box to say the version can be over written.
cheers

Why : Data Control entry not expandable/empty - ADF Task flow based on HT.

Hi All,
I've hoping to create an ADF Task flow based on a human task. I have a stand alone ADF application within the ViewController of which I am attempting to create this task flow. The resultant data control entry doesn't seem to be expandable.
Questions
1. When creating an ADF Taskflow based on a human task, should it always be within a project in the same application as the SOA components?
2. If no, is the resultant human task data control empty or not expandable because the xsd for the HT is based on the MDS? I have configured all the MDS connections within my application.
JDev : 11.1.1.4
Thanks
PP

Hi,
Answers :-
1. No, it is not necessary that your ADF Taskflow based on Human Task should be in the same application where the SOA Project Resides. But for the deployment of that ADF Taskflow you will need the SOA Project.You can add that project whenever you want to deploy.
2. It might be the cause due to the MDS Configuration .
Do one thing , while creating the ADF Taskflow based on Human Task , you do select the .task file via the file system not from the MDS.
If you will select the .Task file of your soa project then it will ask you to name the Taskflow, just name the taskflow as you want and say ok.
After creating the taskflow, it will add a lot of xml files in your project and it will create a data control of it.
Hope it helps!!

Shah
