Task flow inside panelTabbed

I need to design an application whose home page is a panelTabbed with four tabs.
Clicking on every tab has to show a different page flow (task flow). I need every page or view in the task flow to appear inside the panelTabbed.
I have tryed to create the main page as a paneltabbed with four showdetailitem and then try to put the four different page flows as a childs of every showdetailitem but I don't know how to do it. Trying to drag and drop the page flow inside the showdetailitem Jdev displays a context menu suggesting to choose a "Task flow call as button" or Link, but what I need is to directly execute the task flow in the showdetailitem and display the application as soon as I click in the tab corresponding every showdetailitem.
Thank you.

You are using 'Bounded Taskflow with Pages'.
In order to create regions, you should create *'Bounded Taskflow with Page fragments'.*

Calling a bounded task flow (that uses fragments) from another application

Hello,
I'm currently having difficulties calling a task flow located inside another application.
I have application Console which is my main application in which I would like to run other applications within. Inside this Console I have it divided into splitter windows and inside them I have regions. My goal is to be able to call a task flow from another application inside one of these regions but so far I'm having no luck.
My first problem occurred when I created a 'local' task flow to make a call to another application's task flow. When I set the properties to the task flow call, it gave me an error that it could not find the .XML file for that task flow when I ran the Console application. I then proceeded to copy that .XML from the remote application into the Console's WEB-INF directory and I seemed to get a bit farther. The error I get now is saying that I cannot run a task-flow that uses fragments. It's essentially trying to run that task flow as an entirely new page instead of inside the region that it's bound to. It's NOT a dynamic region (although that's the end goal here). So I then changed the other application's task flow to simply display an entire page rather than fragments inside a region and voila, it works..... kind of.
To recap how I was able to call another application's task flow inside the Console:
- I had to manually copy the task flow xml file into the Console WEB-INF directory
- I had to change the task flow so that it didn't use fragments
- I have called the task flow but I lose my console page entirely, no more regions or splitters so I'm back to square one.
If anybody has any suggestions, hints, tips or anything, send them this way and I will be forever greateful.
Thanks,
Mark

Thanks for your response Frank.
Unfortunately the problem seems to be greater than that. I've been able to package task-flows into a jar library and tried importing them that way with no luck.
I'm simple trying to call an external task-flow to run inside a region which is inside a splitter panel that I call my console.
Any other ideas ?

How to pass parameter through URL to bounded task flow with page fragment

I want to pass parameter to Bounded Task Flow With Page Fragment trough URL
as I start this taks flow with router and according to this Param I will rout the user.
I added input param to taks flow named direction and make the task flow called URL invoke url-invoke-allowed
<input-parameter-definition id="__41">
      <name id="__42">direction</name>
      <value>#{pageFlowScope.direction}</value>
      <class>java.lang.String</class>
    </input-parameter-definition>but I don't know how to add this to the JSPX that I will add the bounded task flow Inside.
and How to pass this from URL

Hi,
url-invoke-allowed is only required if the task flow itself is directly accessible from a browser (which is not the case at all if the task flow uses page fragments). To pass input parameters to a task flow that is embedded in a region and that has input parameters, you define the input parameters on the taskFlow Id that is created in the PageDef file of the containing page. To learn ADF task flows, have a look at the videos below. They also contain a sample for passing parameters to a region

Make region/Task-Flow visible/invisible inside the page created in composer mode.

Environent_
JDeveloper 11.1.1.6.0
Webcenter Sites version : 11g R1.
Problem statement_
Below example is to demonstrate the usecase to make region visible/invisible inside the page created in composer mode.
The problem with this case is the 'Show Component' property does not automatically evaluate its expression even after using the contextual event.
We want the region to be refreshed at run-time just like it works with design time pages using Refresh, RefreshCondition attributes in pageDef.
My Usecase_
I have two task flows dragged in Webcenter Customized Page.
First contains Employee list and Second contains selected employee's manager name.
By default when page loads second task-flow/Dragged-Box should be hidden.
When I select employee from first box, then immediately second box should be appeared with manager name.
In the case when If Employee does not have manager, second box should be disappeared. Whole page should not be refreshed only the second box should be refreshed and hide.
Regards,
Niraj

Hi Jiri,
Thanks for your prompt reply..
While referencing the taskflow in any page will create a region and makes entry in pageDef for that page.
In the PageDef of that page I am using Refresh and RefreshCondition attributes of the taskflow tag in order to refresh the taskflow based on certain condition or parameter change.
I want to achieve the same in run-time environment using composer mode. where I have the control over page but do not have pageDef (visually where I can go and add the attributes Refresh and RefreshCondition manually)
I would be obliged if someone can help on this.
Thanks
Regards,
Niraj

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 return values from task flow in af:region ?

Hi!
I'm working with a taskFlow that is rendered inside a popup using the "popup inside a region pattern" (http://www.oracle.com/technology/products/adf/patterns/popupregionpattern.pdf), but now this taskFlow has an input parameter and a return value definition. So the question is how to get a value returned by this taskFlow thas is called inside a region?
Any suggestion?
Thanks in advance!

Hi,
write the value to a shared memory scope like session and read it in the regionNavigation listener. If you follow the paper you refer to then the listener determines of the viewId is null, this a return happens. It wuld then look in the memory scope for the return value.
Another option would be to use an object that you pass as an argument to the task flow you open in the popup. Then you change the object you passed in, which then makes the return information available in teh calling flow. The object you pass in would have to be in a shared scope too

How to add portlets to the task flow page

I am using WebCenter space and I want space users to be able to put the portlets into their group space pages.
All the portlets are under portlet folder in the catalog. However, our requirement was to have a custom folders.
For example, the user administration portlets have to be in something like "user administration" folder and report portlets have to be in something like "report" folder.
By "extending WebCenter Spaces" White Paper, I can create a custom folders and then I can put custom task flows. However, it doesn't say anything about the portlets. I opened SR with Oracle but so far I don't have the answer from Oracle.
So I tried to add portlet into task flow pages after registering the portlet producers. However, it gives me the error portlet unavailable. Do I need additional steps to do this? I need help...

Thank you.
However it is not showing in the catalog.
I used the WSRP producer connection name as provider and id from the portlet.xml file.
rss is my WSRP producer connection name from EM and the id is numeric in my portlet.xml file.
I can see the folder but I cannot see anything inside of the folder.

Oracle ADF task flow setup failing- deployment issue

Hi Experts,
We are facing issue while deploying the ADF taskflow to Oracle webcenter portal/application server.
We will need your help to get any pointers from your Oracle network to help resolve.
Details of issue are as below.
Please help ASAP.
Problem Statement: Issue in the ADF taskflow while it is deployed on Oracle Webcenter Portal/Application server (the ADF taskflow is fetching data from PL/SQL procedure using table/record objects as OUT parameter, which is running fine in Jdeveloper).
Problem Description:
From ADF task flow we are invoking a PL/SQL procedure, which is returning a PL/SQL objects as an OUT parameter, some of these objects are of TABLE TYPE and one of RECORD TYPE. We are invoking this oracle procedure and fetching the object using jdbc. The object to which we are mapping this PL/SQL object is a custom java type object. We are using Jdeveloper 11.1.1.4 and Oracle ADF for this and we are able to successfully fetch the object using the code snippet #1 attached below.
However, when we deploying the same code, i.e. the above ADF task flow in the Webcenter Portal server 11.1.1.4, inside the Webcenter portal application, it doesn’t work and give the below error, error snippet #2 below.
Options tried: Initially we were using oracle.sql.STRUCT to handle the PL/SQL object, we tried changing this to weblogic.jdbc.wrapper.Struct and also java.sql.Struct, however we are still getting same error.
The objective is to get the data from PL/SQL procedure in objects (record, table) as OUT parameters in ADF taskflow deployed on Oracle webcenter portal/application server.

Accessing Human Task Payload from ADF Task Flow

Hi
Using jDeveloper 11g TP4 SOA...
The scenario is this:
1. We have created a Human Task which has parameters accountId and accountType in the payload.
2. We have then created a Task Flow based on that human task.
3. Inside the web folder with task flow we have *4 task display forms* (jspx pages).
4. In the task flow we have the 4 pages and then a router
5. Now we want the router to look in the payload of the human task and based on the accountType redirect to the correct task display form.
Problem: We can't access the human task data control from the router in the task flow.
Does anyone have some insigt into how we can read the accountType from the payload and then pick the correct task display form?

Hi victor,
i'm using a SOA(OSB) based task service, but i think that you have to use a "task service" (or something like this) to update your task
this is my routine
public Task updateTask(Task task) throws Exception {
TaskServiceContextTaskBaseType taskUpd =
new TaskServiceContextTaskBaseType();
taskUpd.setWorkflowContext(getWorkFlowContext());
taskUpd.setTask(task);
return taskService.updateTask(taskUpd);
where taskService is the port of my proxy.
Hope this help

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.

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.

ADF Task Flow Question.

Hi everyone,
Is it possible to call an unbounded task flow from a bounded task flow?
Let me explain.
I have created a template, with an af:navigationpane on top. Inside it, I have placed three
commandNavigationItems: the first two go to simple views.
The third one goes to a page inside of which there's a tabbed panel with multiple detailItems: each of those contains a region made with page Fragments (so, each of one corresponds to a bounded task flow, which doesn't have a return)
Now, If I navigate inside one of those bounded task flow, whenever I try to navigate away from then (using the top navigation bar), I get a "ADFC-02005: Task flow definition not found". I guess it's because the action is defined ony inside the main adfc-config. Is there a way to accomplish what I'm trying to do, or did I completely misunderstood how Task Flows are even supposed to work?
Thanks in advance.
FS.

Very Interesting.
I would say you can call unbounded from unbounded, never tried this. What does the documentation say about calling other taskflows.
If you call an unbounded from a bounded you can't return to this bounded taskflow.
A page fragment bounded taskflow is a page fragment and it only controls that small part of the jsf page. you should use the output parameters of this bounded taskflow so you can interact from this page fragment to the rest of the page.

Best Practice - Bounded Task Flows, Regions and Nested Application Modules

Using JDev 11.1.1.3; understand that it's generally considered good practice to just have 1 root application module servicing model content / services for each page. In our application, we've used a number of bounded task flows and page fragments deployed as af:region's into pages as either a) views targeted in page-flow navigation, b) tab panel content inside a regular jspx, or c) af:popup / af:dialog content. As it stands, we've not engaged nesting of the application modules for this embedded region content, so these regions are no doubt instantiating new AM's if/when invoked. Should the AM's servicing these embedded regions be deployed nested within the root AM's, and then if so, does this change the way that the jsff / fragment content is actually developed (currently as per any other jspx using the DataControl pallete). Or are the best-practice directives talking about a page as being the design-time / declarative composition of content rather than the run-time aggregation of page + fragments ... in which case the fact that our embedded fragments are not using nested AM's is unlikely to concern.
Thanks,

Probably a better question for the ADF EMG: http://groups.google.com/group/adf-methodology?hl=en

Task-flow for inserting record in a popup

Hi all,
I am using Jdeveloper 11.1.1.0.
I have a page with a lot of panelTabbed that displays a lot of data of a table.
I would like to have a button that show a popup and launch a task-flow for inserting data in the table in more steps.
I have created:
1) one fragments for every inserting step
2) a bounded task-flow having an activity (createInsert before the activities (fragments) to insert a new record), with a task flow return (cancel and commit) to save or rollback the data.
3) obviusly, a button that show the popup for inserting a new record. I have inserted the task-flow defined in 2) as a region in the dialog of my popup.
When I launch my page:
1) I see an empty form (instead of seeing the first record)
2) the data inserting on the popup are not saved
3) the second time I try to launch the popup, I see nothing, only the OK button of the dialog.
I know, in the new version of Jdeveloper it is possible to insert a task flow in a popup, but is it possible, in the previous (my) version?
Thanks
Andrea

1) You are seeing an empty form because you are probably calling CreateInsert method of your data control. You should call it only if you are going to create a new record. Also, if this is a new record, you should not show the tabs below. In my case, i am doing like this:
There are 3 pages, ListPage, CreatePage and Edit Page.
User first enters to List page (because it is the default activity in taskflow), to list Master records in a table. There are also 2 buttons, Create and Edit. If Create button is clicked, CreateInsert method is invoked and then CreatePage is called. In create page, there are only 1 form of Master's attributes. After user commits, taskflow redirects the page back to ListPage.
If user selects a row in list page then press Edit button, EditPage is called, but without calling a CreateInsert method. You don't have to invoke any methods if your table in ListPage has a SelectionListener (which is set by default).
in launch listener, you can run a method like this:
public void saveState(LaunchEvent launchEvent) {
DCIteratorBinding ib = ADFUtils.findIterator("YourMasterIterator");
RequestContext requestContext = RequestContext.getCurrentInstance();
//we save key.
String key = ib.getCurrentRow().getKey().toStringFormat(true);
requestContext.getPageFlowScope().put("yourKey", key);
and in return listener:
public void loadState(ReturnEvent returnEvent) {
RequestContext requestContext = RequestContext.getCurrentInstance();
if (null == requestContext.getPageFlowScope().get("yourKey"))
return;

You can find ADFUtils.java and JSFUtils.java in Store Front Demo project and some other sample projects.
2) About the X button... This is the biggest problem of inline-popups. As far as i learned from people in this forum, it is not possible to remove that if you use an inline-popup. And it does not invoke returnListener. But, it does a rollback! I think it is a big problem and i am hoping to find a solution too. Using a popup component instead of inline-popup as dialog can be a workaround.

Hi Deniz,
thank you for you reply.
My task flow is sharing data controls with its caller, because main page displays updatable record, while the button launch a task flow in the popup to create a new record of the same table.
I have understood what you are saying (save the current key when I launch the popup and restore the key when I return from the popup), but:
1) when I enter in the main (caller) page, I see an empty form, and not the first record of my table. Why?
2) the returnListener works even if I close the dialog with the "x" (in the up-right angle of the dialog) or only with its buttons?
3) where can I find the code/links/examples/guides to implement launchListener and the returnListener for my button?
Thank you
Andrea

JDeveloper 11.1.1.5.0 ADF Library task-flow not shown

fyi
Please consider the example application created using JDeveloper 11.1.1.5.0
at http://www.consideringred.com/files/oracle/2011/TestsInADFLibraryApp-v0.01.zip
(in the context of forum thread "JUnit test classes in ADF Library")
At some point, working with that application in JDeveloper 11.1.1.5.0, I used the deployment profile "adflibTestsInADFLibraryApp-ViewController-dp" to create the ADF Library "adflibTestsInADFLibraryApp-ViewController.jar" wich seemed to have an issue.
When in a File System Connection on the Resource Palette, that ADF Library did not show the task-flow(s) it contained.
But, I can no longer reproduce this. If I now try to do the same, the ADF Library seems to be OK. The only thing I can think of that changed, is that JDeveloper has been restarted (a day later).
Showing both ADF Libraries in File System Connections on the Resource Palette illustrates this
at http://www.consideringred.com/files/oracle/img/2011/task-flow-not-shown-jdev111150.png
When I looked inside the ADF Libraries, the respective "task-flow-registry.xml" files were somewhat different:
- in the "broken" ADF Library there were lots of XML namespace declarations
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<task-flow-registry xmlns="http://xmlns.oracle.com/adf/controller/rc">
<task-flow-descriptor xmlns:ns0="http://xmlns.oracle.com/adf/controller/rc" ns0:path="WEB-INF/btf/browse-employees-btf.xml" xmlns:ns1="http://xmlns.oracle.com/adf/controller/rc" ns1:id="browse-employees-btf" xmlns:ns2="http://xmlns.oracle.com/adf/controller/rc" ns2:type="task-flow-definition" xmlns:ns3="http://xmlns.oracle.com/adf/controller/rc" ns3:uses-page-fragments="true" xmlns:ns4="http://xmlns.oracle.com/adf/controller/rc" ns4:library-internal="false" xmlns:ns5="http://xmlns.oracle.com/adf/controller/rc" ns5:train="false"/>
<task-flow-descriptor xmlns:ns0="http://xmlns.oracle.com/adf/controller/rc" ns0:path="META-INF/adfc-config.xml" xmlns:ns1="http://xmlns.oracle.com/adf/controller/rc" ns1:id="" xmlns:ns2="http://xmlns.oracle.com/adf/controller/rc" ns2:type="" xmlns:ns3="http://xmlns.oracle.com/adf/controller/rc" ns3:uses-page-fragments="false" xmlns:ns4="http://xmlns.oracle.com/adf/controller/rc" ns4:library-internal="false" xmlns:ns5="http://xmlns.oracle.com/adf/controller/rc" ns5:train="false"/>
</task-flow-registry>- in the "ok" ADF Library there was only one XML namespace declaration
<?xml version = '1.0' encoding = 'UTF-8'?>
<task-flow-registry xmlns="http://xmlns.oracle.com/adf/controller/rc">
<task-flow-descriptor path="WEB-INF/btf/browse-employees-btf.xml" id="browse-employees-btf" type="task-flow-definition" uses-page-fragments="true" library-internal="false" train="false"/>
<task-flow-descriptor path="META-INF/adfc-config.xml" id="" type="" uses-page-fragments="false" library-internal="false" train="false"/>
</task-flow-registry>- (q1) How can these not shown task-flows (or its different task-flow-registry.xml file) be explained?
many thanks
Jan Vervecken

Thanks for your reply Chris.
