ADF Bouded Task Flow

Hi All,
Does anybody know how to get programatically the default activity in the boudned task flow?
I am using JDeveloper 11g TP3.
Regards,
JavaDeVeLoper

Hi,
taskflows have a defined entry point, which means that you URL reference the taskflow as a whole and not the default activity. By design, bounded taskflows don't allow to explicitly call a view activity contained in it. I think the developer guide is pretty well written in this regard.

ADF train task Flow display name comonent value from bundel

hi
i have som problem with adf bounded task flow train.
i build a bounded task flow as fragment and train and i add display name component to each view , but how i can give the display name value from a view controller bundel .
regards mohammad.j.yaseen

1). Select the component for which you want to set the attribute to a bundle
2). In the property inspector, click the context menu next to the attribute you want to pick from a bundle (the thing that looks like a "V" next to the field"
3). Choose "Select Text Resource..." from the resulting menu

How to Call an ADF Bounded Task Flow Located in Another Web Application

Hi.
I'm working in JDev 11G TP3.
I've read the section from the 11G documentation on Working with Task Flow Activities,
specifically the section 15.5.3 on How to Call an ADF Bounded Task Flow Located in Another Web Application.
I've followed the instructions but still can not seem to call another task flow in another application correctly.
Can someone send a small example specifying how the (TaskFlow Reference) section
should be filled in, and just a general simple outline of process to set the whole process up.
Thanks

Your EL for the remote-app-url needs to return something like this
"http://www.acme.com:80/myapp/faces/adf.task-flow"
where "http://www.acme.com:80/myapp/faces" is the root of the url you'd normally use to access the remote application.
I filed two bugs:
bug 6944247 to improve the documentation
bug 6944246 to fix the fact that you currently have to specify the 'adf.task-flow' part. You shouldn't need to do that. But doing so for now will get it to work.

ADF Security, Task Flow as a region in a page resource grant

JDeveloper 12c (12.1.2); Application uses ADF form based security, external LDAP provider (Active Directory)
After sign-in page (upon successful authentication/authorization) user is forwarded to a page that executes VO method prior to render. I am new to task flow concept and am told to achieve this like:
- create bounded task flow, with method call activity (execute exposed AM method that calls VO method, runs custom SQL) and view activity as page fragment.
- then drop the above task flow into a page as a region
In ADF security setup, I gave resource grant task-flow to certain application role. Started the application, login and got 403 error. Then went back and gave resource grant 'view' to the actual page that contains task flow. It worked fine.
So the question is, when protecting application (implemented with task flows) with ADF security, I thought it is enough to grant those task flows to whatever application roles (groups) and inherently any page that uses that task flow(s) (as a region) will be protected?
From this test, it seems that I have to assign each page (that has task flow as a region) to application roles individually?

Hi,
any page that is contained in a bounded task flow is protected by the task flow permission grant, this is correct. If this is not what you see, please file a bug with support or send me a simple reproducible test case please. My mail address (replace all < name > with the described symbol.
frank <dot> nimphius <at> oracle <dot> com
The test case will need to be in a ZIP file nemaed to "unzip" and should be able for me to run stand alone (please no database scripts to run prior to try the test case)

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-registry>- in the "ok" ADF Library there was only one XML namespace declaration

Call adf bounded task flow library programatically

I have a master application where I have one page with a region where all the task flows are going to be aggregated as tabs. Each task flow represents a module and is in a separate application. I add the adf library to the master application for bounded task flow "Module1".
This is my code that works if the bounded task flow is in the master application:
TaskFlowBindingAttributes tfAttr = new TaskFlowBindingAttributes();
tfAttr.setId("Module1");
tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/module1.xml","module1"));
taskFlowList.add(0, tfAttr);
List<UIComponent> tabs = this.getPanelTab().getChildren();
for (int i = 0; i < tabs.size(); i++) {
RichShowDetailItem tab = (RichShowDetailItem)tabs.get(i);
tab.setDisclosed(false);
RichShowDetailItem tab = (RichShowDetailItem)tabs.get(index);
tab.setDisclosed(true);
But if bounded tak flow is in separate application the code doesn't work, it shows a blank page and i have defined a page with some panel boxes. So how shoud i call the bounded task flow programatically??.
I am working with Jdeveloper 11.1.2.3.0, thank you

Yes I see it in the component palette. I found the problem, I see in the task-flow-registry.xml that the path for the bounded task flow is: "module1.xml" and not "WEB-INF/module1.xml". What sould be the correct path?.

ADF Bounded Task Flow

I have created a bounded task flow which has the following activities: Method Call (default activity and it calls a custom method in a request scoped backing bean), a controlFlow to a jsf page, a controlFlow to a Task Flow Return.
Here is the xml code for the Bounded Task Flow:
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<task-flow-definition id="fromviewprojlist-task-flow">
<default-activity>retrieveProjInfo</default-activity>
<managed-bean id="__5">
<managed-bean-name>backing_ViewProjList</managed-bean-name>
<managed-bean-class>com.dairynet.pts.controller.backing_ViewProjList</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
<method-call id="retrieveProjInfo">
<method>#{backing_ViewProjList.retrieveSingleProjData}</method>
<outcome>
<fixed-outcome>toSummary</fixed-outcome>
</outcome>
</method-call>
<view id="summary">
<page>/projectRequest/projSummary.jsf</page>
</view>
<task-flow-return id="tfrViewProjList">
<outcome>
<name>tfrViewProjList</name>
</outcome>
</task-flow-return>
<control-flow-rule id="__1">
<from-activity-id>retrieveProjInfo</from-activity-id>
<control-flow-case id="__2">
<from-outcome>toSummary</from-outcome>
<to-activity-id>summary</to-activity-id>
</control-flow-case>
</control-flow-rule>
<control-flow-rule id="__3">
<from-activity-id>summary</from-activity-id>
<control-flow-case id="__4">
<from-outcome>toViewProjList</from-outcome>
<to-activity-id>tfrViewProjList</to-activity-id>
</control-flow-case>
</control-flow-rule>
</task-flow-definition>
</adfc-config>
I am calling this bounded task flow from a commandLink that is in an ADF table (partial code of the jsf page that has the commandLink):
<af:table value="#{bindings.VProjectlistQryVO1.collectionModel}" var="row"
rows="#{bindings.VProjectlistQryVO1.rangeSize}"
emptyText="#{bindings.VProjectlistQryVO1.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.VProjectlistQryVO1.rangeSize}" rowBandingInterval="0"
filterModel="#{bindings.ImplicitViewCriteriaQuery.queryDescriptor}"
queryListener="#{bindings.ImplicitViewCriteriaQuery.processQuery}"
filterVisible="true" varStatus="vs"
selectedRowKeys="#{bindings.VProjectlistQryVO1.collectionModel.selectedRow}"
selectionListener="#{bindings.VProjectlistQryVO1.collectionModel.makeCurrent}"
id="resId1" width="100%">
<af:column sortProperty="#{bindings.VProjectlistQryVO1.hints.ProjShortDesc.name}"
filterable="true" sortable="true" width="169"
headerText="#{bindings.VProjectlistQryVO1.hints.ProjShortDesc.label}"
id="resId1c1">
<af:commandLink action="fromviewprojlist-task-flow" id="cl1"
text="#{row.ProjShortDesc}"/>
Here is my code in the adfc-config.xml file related to the page calling the bounded task flow and the bounded task flow:
<control-flow-rule id="__7">
<from-activity-id>masterList</from-activity-id>
<control-flow-case id="__5">
<from-outcome>fromviewprojlist-task-flow</from-outcome>
<to-activity-id>fromviewprojlist-task-flow</to-activity-id>
</control-flow-case>
</control-flow-rule>
<control-flow-rule id="__6">
<from-activity-id>fromviewprojlist-task-flow</from-activity-id>
<control-flow-case id="__9">
<from-outcome>tfrViewProjList</from-outcome>
<to-activity-id>masterList</to-activity-id>
</control-flow-case>
</control-flow-rule>
When I click the commandLink where the action is the bounded task flow (fromviewprojlist-task-flow), it does not go into the method I am specifying in the Method Call activitiy (the default activity) within the task flow. It does not error out, but it does not go anywhere. My objective is to go to the custom backing bean method so I can get some value of the row in the table I clicked on, then use this value to successfully load the projSummary.jsf page
I am new to this, and I can't figure out what I'm missing. I appreciate any ideas you may have to help me resolve this.
Thanks!

I did as you suggested, but I see nothing in the console that indicates it's trying to run the bounded task flow. It's like it ignores it. No error, just redisplays the page I'm calling the bounded task flow from.
Previously, in another application, I created a bounded task flow with the default activity which was a Method Call activity, but I dragged and dropped a createInsert operation onto the Method Call activity from the Data Control. This worked fine (for creating an inputForm).
With this bounded task flow that is giving me problems, I'm not referencing the Data Control at all, I'm just referencing the method in the request-scoped backing bean. Is there something I don't have "wired up" correctly so that it's not even finding the bounded task flow the action attribute of my commandLink is referencing?
I'm not referencing the model (or an application module) at all, but should this matter? It seems like it should just find my backing bean method, run it, and carry on!

ADF Mobile : task-flow navigation takes at least 500 milliseconds

hi
While navigating the CompGallery sample application [1] I noticed that navigation between (what looks like) simple pages/views was rather slow.
Surely, this can be caused by different things (possibly the device, the app implementation, the framework, ...).
To review this, I tried to build a simple example application using JDeveloper 11.1.2.3.0
at http://www.consideringred.com/files/oracle/2012/NavigationTimeMApp-v0.01.zip
and as APK at http://www.consideringred.com/files/oracle/2012/navigationtimemapp-v0.01.apk
It has a bounded task-flow with two views that allow to navigate to each other.
see the screenshot at http://www.consideringred.com/files/oracle/img/2012/navigationtimemapp-20121025.png
It has a simple TimerBean that allows to get an idea about how much time navigation requires:
public class TimerBean
     protected long fStartTimerMillis = 0;
     public void startTimer(ActionEvent pActionEvent)
          fStartTimerMillis = System.currentTimeMillis();
     public String getTimerInfo()
          if (fStartTimerMillis == 0)
               return "no timer info yet";
          long vMillisAgo = System.currentTimeMillis() - fStartTimerMillis;
          return "timer started " + vMillisAgo + " milliseconds ago";
}It allows for the following scenario (sc1):
- (sc1-a) start the app
- (sc1-b) click the "do goSecondView using a_TimerBean" button, which will navigate to "secondView" showing something like "timer started 621 milliseconds ago"
- (sc1-c) click the "do goFirstView using a_TimerBean" button, which will navigate to "firstView" showing something like "timer started 537 milliseconds ago"
- (sc1-d) if you care to stop the app, try a "Force stop" on the "App info" via "Apps" in the Android settings
On my HTC Sensation Z710e I always get at least 500 milliseconds for each navigation.
questions:
- (q1) Anyone who wants to try scenario (sc1) and share his observed navigation times?
- (q2) Which navigation times can be expected for simple navigation in ADF Mobile apps (like in scenario (sc1))?

But, I don't see a big improvement, maybe about 50 milliseconds improvement per navigation (so, about 450 milliseconds instead of about 500 milliseconds).
... so page navigation performance (and overall UI performance) is primarily dictated by JS performance by the web engine on the device. ...How can I determine (in the app) which "JavaScript / web engine" a device uses?
At the end of the day, the actual performance of your application will be largely dictated by how you access data and the complexity of your screen. ...Sure, but I explicitly avoided those aspects here to have some kind of "base line" behaviour before introducing other complexities (that can slow things down).

WebCenter/ADF Bounded Task Flow Permissions 11.1.1.4

Hello All,
I'm seeing some strange behavior related to permission on bounded task flows within a WebCenter Portal Application created with the 11.1.1.4 WC extensions.
I created a bounded task flow and added a view activity and a return activity to it. I have provided "Administrator", "anonymous-role", and "authenticated-role" application roles with view permissions for the task flow resource in "jazn-data.xml". I also added the page related to the view activity in the bounded task flow to my page hierarchy file "page.xml", and provided users with view permissions there.
What I'm seeing is that anonymous users can view pages in this bounded task flow just fine, but authenticated "Administrator" role users cannot.
Am I missing a configuration setting somewhere?
Thanks

Certainly... I've uploaded the sample application here: http://rapidshare.com/files/456317758/WebCenterTestApp.zip
To make this simple, I've used the OOB, pre-configured, Web Center Portal application template with default project files. Run the "home.jspx" page. I've removed the customization panel and added a button command whose action invokes the control flow to the task flow call activity for the bounded task flow. The task flow has a single page, and I have it being displayed as an inline pop-up... just for fun.
Before you login, click on the button to see how the anonymous user can view the bounded task flow page. After you return from the task flow, login and verify that the admin user sees the app auth error page in the dialog instead.
I've configured one admin user in jazn-data.xml: myadmin/myadmin1
Cheers

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?

Passing parameter from task flow to another ADF Taskflow

Hallo everyone, I have a case :
1. I have ADF Bounded Task Flow, it contains two main elements - page P1 and another ADF Task Flow call - C1
2. Page P1 has an atribut employee number as command image link,
this command will call C1 and passing empNum as parameter
3. C1 containts two page fragment , Pf1 and Pf2. Default activity is Pf1
4. Ineed to pass parameter empNumb available in P1 into ADF Task Flow call C1..
Is it possible when I click command image link, then it will call Pf2 in C1 ?
Please help.
Regards,
samantha

Hi Samantha,
You mean to say, u want to skip the default activity Pf1 in C1?
And for passing parameters use Add a parameter in your taskflow. (put the empnumber in pageflowscope and pass that as a parameter to the new taskflow C1).
Thanks

Navigate betwen bounded task flows

Hi,
I build ADF UI for BPM. In my application I have a few bounded task flows (allowed url invoked) coresponded with human tasks, and inwoked form BPM Workspace. Unbounded task flow or any start page for application is unused. In my case, user invokes bounded task flow, but should have possibility to navigate to another bouded task flow directly. What is the best way to perform this navigation ? How to do it prorammatically ?
Kuba

When you want to invoke another taskflow from the current taskflow -- you could use task flow call activity if it is an one-off case.
But if you have same scenario across all of the taskflows in the same applications, i would have to exit the current taskflow and invoke the other taskflow.
This is a well defined pattern and documented in the following post:

How to filter View Objects on Main Page - Unbounded Task Flow

Hi All,
Version: 11.1.1.4
I have a scenario where I am trying to filter the Employee information by EmployeeID and show their related Items. I can do this if I encapsulate Employee and / or Items in bounded task flows and expose their view Criteria in methods that I am setting on the App Module. I could also add the bind variable to the View Object queries. The problem I am having is that I want to display a pop up based on the item they select. My issue is that I can't seem to figure out how to either grab the item row selected and pass it to the pop up (Can't create a control flow from a page fragment to a page - which as far as I can understand the pop up in the task flow has to be a page and not a page fragment) or drop the employee view object and item view object on the main page and have them be filtered.
So basically two issues:
1. If I use the Employee and Item bounded task flows and place them as regions on the main page then I am having difficulties passing the row selection (item selected) and pass it to my pop up window (another task flow).
2. If I place the employee and item view objects on my main page the original methods I am using to filter the data are not getting called at all. I have tried placing them in the adf-config task flow prior to my main page view and going into my main page page def and adding them as method calls in the binding.
I am sure I am doing something wrong or maybe even creating an invalid approach, but I should be able to filter my employee and item data on load within my unbounded task flow or use the data within my bounded task flows and generate a popup with data I am collecting from my item row.
As always greatly appreciate the feedback....still really ignorant with ADF.
--S

I figured out the issue Shay. I didn't have my pageFlowScope value set on the task-flow-call. So I had the parameter name and value set on the input of my downstream bounded task flow, but when I add the control to call the task flow I didn't have the task-flow call value set. That piece was not intuitive to me. It makes sense that it would have to know how to pass the value.....just wasn't sure where it should be set.

How to pass a parameter to a bounded task flow?

Hi,
We are facing issue while passing parameter from a bounded task flow to another bounded task flow and then showing the passed parameter in a jspx page.
We have a caller task flow with following component:
1. A jspx page
- In this jspx we have a text box have its value as #{pageFlowScope.inputvalue}.
- Also we have a command button which has its "Action" as the control flow that leads to the "called" task flow.
2. A bounded task flow named "called".
So, we call the "called" task flow on the button click in the jspx page.
Also, in called taskflow we have a jspx page where we are using a output label to show the parameter passed from caller task flow to the called task flow.
We performed the following steps to set the parameter passing from caller task flow to the called task flow.
1. Select the input text component on the JSF page.
2. In the Property Inspector, enter a value for the input text component. You can specify the value as an EL expression, for example #{pageFlowScope.inputValue}.
3. In the Application Navigator, double-click the name of the called task flow to open its diagram.
4. Click the Overview tab for the called task flow.
5. Click Parameters and expand the Input Parameter Definition node.
6. Click the Add icon next to Input Parameter Definition.
7. In the Name field, enter a name for the parameter, for example, inputParm1.
8. In the Value field, enter an EL expression where the parameter value is stored and referenced, for example, #{pageFlowScope.inputValue}.
9. In the Class field, enter a Java class for the input parameter definition. If you leave the Class field empty, its value is by default implicitly set to java.lang.String.
10. In the editor, open the diagram for the calling task flow.
11. In the Application Navigator, drag the called ADF bounded task flow and drop it on top of the task flow call activity that is located on the calling task flow. Dropping a bounded task flow on top of a task flow call activity in a diagram automatically creates a task flow reference to the bounded task flow.
12. In the Property Inspector for the task flow call activity, click Parameters and expand the Input Parameters section.
13. Enter a name that identifies the input parameter.
14. Enter a parameter value, for example, #{pageFlowScope.parm1}.
Now when we try to fetch the value of parameter using #{pageFlowScope.parm1} in the jspx in called taskflow, its not giving the desired value.
We even tried to set the to and from parameter of the jspx in called askflow. But no success.
Can anyone let us know if we are doing smething wrong or exact steps to configure passing of parameters to a bounded task flow and retrieving it in a jspx page will also help.
Thanks in advance.

Hi Tushar,
In step# 14, the value should be "#{pageFlowScope.inputValue}" (should be the same as the value in step#2) .
