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 return redirect to page?
Hello, I am using JDeveloper 11.1.2.3.0
I have build a task flow (bounded task flow) in my application and I want to redirect on task flow return, to another page from the application. This page is not part of the flow. From what I am reading till now everything I found is to call another task flow on return, but I do not need this. I just need to redirect to a specific page. Can anyone help on this?
Thank youThanks but is there no possibility at all to navigate to another page within the aplication (not of the same task flow)? I was thinking something like FacesContext.getCurrentInstance().getExternalContext().redirect("Page1") on action method on a button of the page; But I am getting an error saying that can not find the Page1.

Print JTable with Multiple pages and rows
I took the printing example at http://java.sun.com/developer/onlineTraining/Programming/JDCBook/advprint.html#pe and modified it a bit to include the following:
1) To Print Multiple pages
2) To wrap lines that is too long for the column
3) To print with a more proffesional style, so that it doesn't look like a screen capture is printed
4) To align the numbers to the right and center column headings

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

HelenHi 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

Create ADF Task Flow for Human task outside of SOA Composite
Hi,
Is there any way you can create ADF Task Flow form (for the task Details to be display in worklistapp) for a Human task out side of the SOA Composite applicaiton?. I know we can create ADF Task flow form for task details based on Human Task in SOA composite application. But I dont want to do that. I dont want to keep any association between Human task and ADF Task Flow.
If there is a way to do this, How can we assiciate this ADF Task flow form with worklist applicaiton?
Thanks

Is this possible to display standard JSR-286 data in ADF Task Flow WCP Page
Below is my scenario,
I have one Webcenter page. Portlet-A (standard JSR-286 based portlet) consumed from WSRP Registration process and Taskflow-B ( with Fragments ) consumed as region from ADF library jar.
On the submit of an Drop down menu/submit button in Portlet-A , I want display selected data in Taskflow-B.
Please help me out.Hi Yannick,
Thanks a lot for the information. It worked.
The portlet data can be accessible using bindings, but parameter name can be different.
Meanwhile I have got one more scenario, where the Portlet and Task Flow placed in different pages of WCP Application. On change of data in the Portlet the application should navigate to another page where the Task Flow placed and displays selected data.
Basically I can not use any button for navigation. The navigation should happen once I do some action in Portlet.
Is this possible? If yes can you please let me know the steps?
Thanks in advance!

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, AlIt 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! -
How do I create a single PDF file with multiple pages?
Hi, I occasionally need merge several jpg images into a single pdf file with multiple pages (one Jpg per page). I have tried doing this on Preview, and by selecting all the pages I want to include in my document and trying to save to Pdf through the "Print" function, but every time it only saves the first page.
Can anyone tell me if there is a way to save multple-page pdf files without having to purchase a specific program (i to this too infrequently to justify the cost)?
Thanks very much,This works for me...
Open first image in Preview View > Sidebar. Drag the other images into Sidebar, then select all.
From File menu > print selected images. Choose PDF > Save as PDF

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.Hi,
I am not aware of a public API for this

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! -
ADF Task Flow based on HumanTask - Region withiin Task form
Hello All,
Was wondering if anybody here has sucessfully used region in their human task forms? I really like the idea of regions and after going through the tutorial here* I tired to implement it.
Following are some additional details of the issue I'm facing.
I have created a UI project based on a human task. The main <human task>_taskFlow.xml is bounded and non-fragmented. I then dropped 'view' component within this task flow and create a blank jspx page underneath. I then dragged and droped another bounded and fragmented task flow (which is also a train) on to this jspx page. The 2nd task flow has some jsff pages in a train. When I deploy run this bpm project,I can't see train form within the region and I get following Null Pointer Exception on the server:
java.lang.NullPointerException

Create Custom ADF Task Flow for BPM
Hi,
I'm working an project on BPM and I'm required to create a custom ADF task flow with multiple views based on the human tasks in BPM. Since I'm new to ADF, could some one please give me some pointers?
Thanks,
DebojitHi,
You have to implement your own custom worklist screens for such a subject. As you know the OOTB worklist screen shows the logged-in users' assigned, etc. tasks. You have to implement the API of SOA workflow.
You can check Mark Nelson's blogs on Redstack to accomplish this. Hope this is the answer of the problem you are looking for. -
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.
ThanksHi 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
<permission>
<class>oracle.adf.controller.security.TaskFlowPermission</class>
<name>/WEB-INF/oracle/iam/ui/sample/homepage/tfs/hello-world-tf.xml#hello-world-tf</name>
<actions>view</actions>
</permission>
