Dynamic regions and taskflow in an adf library 11g

Hi,
I am facing a small issue. I have a an adf view project that uses an ADF Library containing a task flow. This view project has the following.
1. A main page (with a splitter panel) that has two buttons (showpage1 and showpage2 as dynamic region links) which display a message from either of these pages in a dynamic region in the page. These two pages have their separate bounded task flows.
This works great, i can click on either of these buttons and the dynamic region displays the default views of these task flows one at a time.
2. When i add yet another button for a bounded task flow that comes from the above-mentioned adf library things break. Now i am able to only display the view from the 3rd taskflow by clicking the corresponding 3rd button. Clicking on showpage1 and showpage2 buttons do not show corresponding taskflows/views.
I can send you my sample project right away if you wish.
Thanks,
The only difference seems to be that the following info. is added in web.xml when I start using the adf library's task flow.
<filter>
<filter-name>ADFLibraryFilter</filter-name>
<filter-class>oracle.adf.library.webapp.LibraryFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ADFLibraryFilter</filter-name>

</servlet-mapping>

Hi Can you send across your sample app where you are using the library and the ADF library as well to [email protected]? I'll take a look and letyou know. Thanks.

How to use a menu model with a dynamic region and a task flow parameter

I am using JDeveloper/ADF 11.1.2.1
I have a menu model that changes which task flow is displayed in a given dynamic region using a backing bean. That works fine. I would like to be able to pass parameters to that task flow based on which menu item is clicked. For example: i have a task flow which shows a page where input fields are used to filter a table. Depending on the value of the task flow parameter I want to change which input fields are displayed. So i will have multiple menu items which refer to the same task flow but have a different set of parameters. I have tried using request scope variables and setting them in the backing bean for the dynamic region which works until the query is submitted at which point the request scope has changed and the value is no longer available. I have tried a number of other 'creative' approaches but have not gotten anything to work. Anyone done this before? Or have an idea on how to solve it?

Frank,
I did a fair bit of digging based on your suggestions and some things I found in your Oracle Fusion Developer's Guide book and I came up with something that works really well. It is fairly elegant but requires code. It would be nice if something like a setPropertyListener could be rolled into the menu model. That would make my solution completely declarative.
Here is my solution:
My task flow requires a the value #{pageFlowScope.type} to be set. My application has a dynamic region that is changed on the fly using a menu model. The region uses a backing bean (mainRegionManagerBean) which is in the viewScope to manage what taskflow is shown in the region. There are multiple menu items in the menu model that point to the same task flow but pass different values to the #{pageFlowScope.type} parameter. So i wired the menu items up to different methods in the mainRegionManagerBean which set the value for me. See the relevant code below.
I would be very interested in the feedback from someone with more experience than I on my solution. Maybe there is a more elegant way...
In the backing bean there is a primary method that was created by generating a dynamic region link which sets the task flow id and then other methods which call it and set the relevant parameters. (JSFUtils is a helper class i wrote to centralize some common tasks):
public String shipmentTraceMasterTaskflow()
taskFlowId = "/WEB-INF/taskflow/master/shipmentTraceMasterTaskflow.xml#shipmentTraceMasterTaskflow";
JSFUtils.setValue("pageFlowScope.type", "");
return null;
public String shipmentTraceProNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "pronumber");
return null;
public String shipmentTraceBOLNumber()
shipmentTraceMasterTaskflow();
JSFUtils.setValue("pageFlowScope.type", "bolnumber");
return null;
In the menu model (notice that these reference the different methods from above):
<itemNode id="itemNode_ProNumberTrace" label="ProNumber Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceProNumber}" focusViewId=""/>
<itemNode id="itemNode_BOLNumberTrace" label="BOL Number Trace" action="#{viewScope.mainRegionManagerBean.shipmentTraceBOLNumber}" focusViewId=""/>
On the page:
<af:region value="#{bindings.dynamicRegion1.regionModel}" id="r1"/>
In the pagedef:
<taskFlow id="dynamicRegion1" taskFlowId="${viewScope.mainRegionManagerBean.dynamicTaskFlowId}" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding" Refresh="ifNeeded">
<parameters>
<parameter id="type" value="#{pageFlowScope.type}"/>
</parameters>
</taskFlow>

Dynamic Regions and parameters - issue

Jdev 11.1.1.6
I have a main page that contains a dynamic region. I want to pass parameters to the region.
Note that I have successfully created parameters for a NORMAL region inside a "parent" form. With a normal "child" region in a "parent",
1. Open the "child" taskflow, click on the whitepace, go to overview, then paraemeters and define a parameter name and value, ex: InputParam and #{pageFlowScope.InputParam}.
2. Open the "parent" form, click on the region, go to bindings, and edit the region. You see the parameter you specified, InputParam and you can enter a value. This value will come from the parent.
3. Set refresh to if needed.
However,
With a dynamic region containing more than one "child" taskflow, I am getting an error. I do everything the same above.
However, when I have the taskflow selected on the bindings tab of the parent form, and click on the structure window, parameter node, The ID text field is surrounded by orange, and a message displays that the reference to "InputParam" is not found.
How are the name or id values specified for a dynamic region? How does one map a parameter from the parent to the "child"? Do you need to put this into a bean?
Thanks,
Stuart

1) Parent A tasflow contains Child B taskflow.
2) Child B expects a parameter called 'inputParameterChild'
3) This will be defined inside the child B taskflow with 'java.lang.String' and value as '#{pageFlowScope.inputParam}'
4) When you click the child B taskflow in parent A taskflow you will see the parameter expected by child B as 'inputParameterChild'
5) Now you can pass the value as '#{pageFlowScope.inputParam}' , here you should have the inputParam set in the bean or in the parent taskflow as explained in step 2 and 3
are you still facing the issue?

Dynamic region bugs and bad documentation

I cannot get the second taskflow to behave correctly in a dynamic region.
Here's my scenario:
In the pursuit of resusablilty, I have two taskflows that are coming from ADF Library Jars into a master application.
Both taskflows have their own associated application modules, which appear as data controls in the master project.
Following the instructions in the Fusion Developers guide, I create a dynamic region and dynamic links.
After swapping to the second task flow, when I click on a different table, I get an error that a target is unreachable:
Target Unreachable, 'RoleId' returned null
For more information, please see the server's error log for an entry
beginning with: Server Exception during PPR, #1{code}
I posted the problem originally under this thread: [dynamic region errors
and got a response that I didn't understand -- both taskflows have data-control-scope = shared.
In contrast to the problem using a dynamic region, if I build a different page in the master application and use each taskflow as *separate* regions (via a tabbed panel), they work fine.
So it doesn't seem there is anything wrong with the taskflows per se, but rather something in the dynamic region switching mechanism that is broken.
I'd appreciate hearing from anyone who has had similar problems or anyone who knows of a solution.
In exasperation, lili5058
UPDATE
Sorry for the earlier rant. I figured out the reason for the odd behavior and it has to do with the code generated by the wizard. This code isn't so much wrong as it is short-sighted. Here's the code generated for the managed bean by the wizards for creating a dynamic region and dynamic link that is put into *backingBeanScope*:
{code:java}package view.beans;
public class DynamicRegionBean {
private String taskFlowId = "/WEB-INF/taskflow1.xml#first-taskflow";
public DynamicRegionBean() {
public TaskFlowId getDynamicTaskFlowId() {
return TaskFlowId.parse(taskFlowId);
public String firstTaskflowtaskflow() {
taskFlowId = "/WEB-INF/taskflow1.xml#first-taskflow
return null;
public String secondTaskflowtaskflow() {
taskFlowId = "/WEB-INF/taskflow2.xml#second-taskflow";
return null;
}{code}
The user is taken to the second task flow by clicking the link that executes the secondTaskflowtaskflow() handler, however, any subsequent requests take the user back to the first taskflow, i.e., the one assigned to the private instance variable, since that's how the wizard wrote the code. This explains why the table on the second taskflow displayed "Fetching Data . . .". The table's content delivery was set to lazy, so when the browser issued the AJAX request to get the data for the table, the task flow switched back to the first one and thus making the data unavailable. Changing the the content delivery attribute value to immediate, brings up the data initially, but any subsequent work on that taskflow routed the user right back to the first taskflow.
I ended up fixing the problem by adding the TaskFlowId (data type) to the pageFlowScope map, so it would be remembered across requests until the user deliberately requests a different taskflow.

Hi,
chances are you are hitting a bug. But this is hard to say from here. If you want, we can further track the issue down. I suggest you exclude the use of ADF libraries and verify that the scenario works if the two taskflows work in the mentioned scenario of they are both defined in the project itself. If this works then it seems like a bug that should be filed. Can you verify this ?

Problem with taskflows within the Dynamic region

Hi,
I am creating a application which have two bounded taskflows search-flow and admin flow.In admin-flow taskflow i have two jsff pages admin_login and welcome.whenever we click login button present in login.jsff it should navigate to welcome page.I have created the control flow case (from outcome is welcome).I have created a Home.jspx in adfc-config.xml.Using the splitter i divided the page into two facets.In facet 1 there are two command links search, admin.In the second facet i have dropped search flow as dynamic region and written the following beanclass.
package com.Search;
import oracle.adf.controller.TaskFlowId;
public class Search {
private String SearchtaskFlowId = "/WEB-INF/Search-fllow.xml#Search-fllow";

else
return TaskFlowId.parse(AdminTaskFlowId);
public void setCurrentTF(String currentTF) {
this.currentTF = currentTF;

How ADF save client state for dynamic region

Hi,
I am wondering what is the best value for "org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS"?
Our application uses one single dynamic region to render a lot different user menu items outside the region, each menu item corresponds to a bounded taskflow. So if user clicks the back button, user will always goes back to login page.
Moreover, when the content of the dynamic region change (taskflow id change), is the client state of the previous taskflow UI's state of the region still tracked by adf? Looks like not necessary but I just want to confirm.
env: jdev11.1.2.1
Many thanks.

Hi,
when you switch a dynamic region then the task flow displayed in the region is discarted and no client state other than the current is saved. Each change of the dynamic region changes the current view Id but does not replace it

Navigate to initial task flow in dynamic region with JDeveloper 12c

I have a home page with a dynamic region and three links and I am working with page fragments. The initial bounded task flow is "btfInicio".
The requirement is that in each bounded task flow I have to implement a close button to return to the initial bounded task flow. This is my code:
My Bean for my home page.
public class AdministradorActividades extends DataControlBean {
    private HashMap parametrosGenerales = new HashMap();
    private String taskFlowId = "/WEB-INF/btfInicio.xml#btfInicio";
    private RichRegion regionPrincipal;
    public String gestionarDatosClinicos() {
        taskFlowId = "/WEB-INF/datosClinicos/btfDatosClinicos.xml#btfDatosClinicos";
        refrescarRegion();
        return null;
    public void refrescarRegion(){
        AdfFacesContext adfContext = AdfFacesContext.getCurrentInstance();
        UIComponent region = findComponentInRoot("rPrin");
        adfContext.addPartialTarget(region);

                  parametersMap="#{pageFlowScope.managerRegion.parametrosGenerales}" Refresh="ifNeeded"/>
I have tried this inside a fragment from my bounded task flow "btfdatosClinicos" where I have a button , but doesn't work. The home page is not refreshed:
        AdfFacesContext adfContext = AdfFacesContext.getCurrentInstance();
        AdministradorActividades admActividades = (AdministradorActividades) adfContext.getPageFlowScope().get("managerRegion");
        admActividades.setTaskFlowId("/WEB-INF/btfInicio.xml#btfInicio");
        UIComponent region = findComponentInRoot("rPrin");
        adfContext.addPartialTarget(region);
If I Implement a control flow case inside my bounded task flow "btfdatosClinicos" to "btfInicio" then I can see the page fragment that correspond to the bounded task flow "btfInicio", but if I clic one of the three links, then the action event is not executed.

Hi Miguel,
I think you are complicating the requirement without needing. Why would you put the back button inside your other taskflows? This would be useful just if you are calling those from another bounded taskflows.
Look what you can do;
You can create your links for dynamic regions. Cool. But in your decorative box, in the top facet, you can drag a drop the btfinicion and display it as a link (yes, this will be your back button). and that's it. You don't need to mess with partial triggers or refrescar regiones methods.
Let me know if this doesn't impact your requirement.
By the way, en que pais trabajas?
Saludos

Open popup in dynamic region once region changes flows

I need to open a popup in a flow if boolean is set to true in the pageFlowScope bean of the dynamic flow bean used in a dynamic region. The parent page/flow is configured in the adfc-config.xml and is controlled by a session bean.
So the scenario is the main page has links to several different pages, each of which has a mean of editing a widget. The Widget edit page has a Tree object that lists the items by user defined categories. Double the tree widget opens a popup with the editor section for that particular widget. These widgets rely on each other and if there is a problem in a contained widget, then I provide a clickable link to go to that object. I'm able to get the main page to change regions to the correct widget flow.
Once I get to the new widget control flow, the tree is displayed as usual and in the pageFlowScope bean I've set a boolean and populated the widget definition for display. Unfortuately, I have found a way to open the popup.
I've tried a phase listener calling a method in the parent page. However, I'm not able to find the pageFlowScope bean by any means. I've set the pageFlowScope bean into the session and get it in the phaseListener method, but all attempts to show the popup seem to go into the great void. I've even added a button with the actionListener to pageFlowScope.myBean.showPopup, but can trigger the action event for that either.
Using: JDeveloper 11g. Not using BC. Any help would be greatly appreciated.

Thank you. That worked.
I have one more question. How can I change the task flow in the dynamicRegion from another taskFlow. For example: I have taskFlow1 loaded into the dynamic region and I want on a button click from taskFlow1 to load taskFlow2 into the dynamicRegion. Is it possible?

Dynamic Region: what am I doing wrong?

Jdev. 11.1.2.3.0
I have been having problems with dynamic regions.
I have two adf forms; mainPage.jsf and mainRegion.jsf. I have also two adf forms (page fragments), employee.jsff and department.jsff, I have also two bounded task flows; employee-task-flow and department-task-flow. In the mainPage.jsf, I have two buttons, employee and department.
What I want to achieve is that when a user clicks the department button, the department-task-flow will be rendered on the mainRegion and when the employee button is clicked, the employee-task-flow will be rendered.
In the mainRegion.jsf, I dragged the department-task-flow on to it and I choose dynamic region. I also dragged the employee-task-flow and I choose dyanmic link. The department button is bound to this method#{TestRegionManagedBean.departmenttaskflow} while the employee button is bound to this #{TestRegionManagedBean.employeetaskflow}.
When I ran the application, the mainPage displays, however, when I clicked on any of the buttons, it does not display anything.
This is the managed been:
package view;
import oracle.adf.controller.TaskFlowId;
public class TestRegion {
private String taskFlowId = "/WEB-INF/department-task-flow.xml#department-task-flow";
public TestRegion() {
public TaskFlowId getDynamicTaskFlowId() {
return TaskFlowId.parse(taskFlowId);
public String employeetaskflow() {
taskFlowId = "/WEB-INF/employee-task-flow.xml#employee-task-flow";
return null;
public String departmenttaskflow() {
taskFlowId = "/WEB-INF/department-task-flow.xml#department-task-flow";
return null;

Try as follows
public void launchPage(String taskFlowId) {
    getDynamicTabRegion().setTaskFlowId(taskFlowId);
    refreshCurrentPage();
protected DynamicTabRegion getDynamicTabRegion() {
    FacesContext fc = FacesContext.getCurrentInstance();
    DynamicTabRegion dynamicTabRegion =
        (DynamicTabRegion)fc.getApplication().evaluateExpressionGet(fc,
                                                                    "#{viewScope.dynamicRegion}",
                                                                    Object.class);
    return dynamicTabRegion;
private void refreshCurrentPage() {
    FacesContext context = FacesContext.getCurrentInstance();
    String currentView = context.getViewRoot().getViewId();
    ViewHandler vh = context.getApplication().getViewHandler();
    UIViewRoot x = vh.createView(context, currentView);
    context.setViewRoot(x);

ADF Library Jar: Bundle-Classes-Information for Declarative Component

Hi,
when we deploying some adf-taskflows as a adf library jar we can add some content with technical namings and user friendly strings.
see the good adf code corner example: [url http://www.oracle.com/technetwork/developer-tools/adf/learnmore/52-taskflow-in-lib-169195.pdf]Advanced Tip: Customizing the ADF Task Flow name in the ADF libray (Page 16)
Is this also possible for declarative components?

Swap task flow in dynamic region from menuitem in menubar

Hello,
I have a dynamic region and two task flows. I have action listeners that swap the task flows into the dynamic regions. When these action listeners are tied to buttons, everything works as expected, but if i attach them to menuitems on a menubar, despite the fact the the listener is executed (based on log file debugging), the task flow in the region does not change.
Can anyone please give me an idea why, and exactly how someone can swap a task flow in a dynamic region from a menuitem.
I'm using Jdeveloper 11.1.1.0.1
Thanks

Hi,
My guess is that the region is not added to the list of partial targets. Add a partialTrigger on the region pointing on the menu item.
p.s. Code snippet would really help to get a more precise answer here

TP4 reusing ADF library migration problem

Hello,
I have an application containing multiple Business Components and View Controller projects.
Common functionality is shared as ADF library between view controller projects. The applicatio was created with TP3 and is working just fine. When ported to TP4, it seems that part of the functionality shared as ADF library is not working.
To be more specific: the login page is using a backing bean to check the authentication details against the database. The following code is working properly:
        appModule =
                (ApplicationModule)((DCBindingContainer)getBindings()).getDataControl().getApplicationModule();But, when accessing the BC module from a phase listener using the following code:
        DataControl dc = event.getLifecycleContext()
            .getBindingContext()
            .findDataControl("SharedModuleDataControl"); DataControl is null.
The same phase listener is working properly when used within the project it was created (and not as imported ADF library)
Once again, this is happening with TP4, with TP3 everything is working fine.
Thanks,
Florin Marcus

Gabrielle,
The root of the problem is that JDeveloper makes a copy of the adf-faces-impl.jar in the WEB-INF\lib directory in your project directory. So what was happening is the project contained to old version of this library that still referenced the "selected" attribute. When you built and then ran the project against the new runtime libraries that no longer had this "selected" attribute, the error occurred.
So the solution to this problem would be for JDeveloper to not copy these libraries into your project directory or to detect that the version has changed and warn you or prompt you to copy the libraries again.

How to make changes in an existing adf Library

Hi,
I am having an adf library, I am looking to make some changes in that adf library and put it back into the project.
Please let me know how to make a jdeveloper project from the existing adf library,as I not having the original project from which this library was created.
Please help..
Thanks

Hi Timo,
I have created an adf project and have created an adf library using the same.
Now when i am creating the adf library using the same project its giving me some errors, so looks like I have done some changes in the original project which might be causing the issue.
So this is the reason I was looking for an option to rebuild the project using adf library files.
I need to do some changes in jsf file of the deployed adf library.
Thanks again for your help

Please give me tutorial links or suggestions to fullfill this...Thanks in Advance

thank you for your response,I want a slightly different need consider two links on Left side and Global Tabs (two tabs Tab1,Tab2 containing page Page1,Page2 which is inside View activity view1,view2 in the unbounded task flow) on the right of panel splitter.By clicking the second button/link ,I want to open the Second global tab (assume default First global tab is opened) and to launch the fragments automatically.In other words I want to open the different global Tab and to launch the fragments automatically by a single click. By using "action" option we can navigate to different page by this we can open the other global tabs but the actionListener (EL to backing bean)did not get into action i.e., not loading the fragments into the loaded page.

PDF rendering with PL/SQL dynamic region

The problem with the reporting is:
- if you want flexible, enhanced reports you can't use the report engine
- PDF output works only with the report engine
Means: At the moment you can't do enhanced, printable reports with HTML DB without using OAS & Developer.
Is there some possible way to generate custom xml from dynamic regions and pass it to the render JSP ?
Is this XmlHttp object in "htmldb_pdf.js" generating the xml output all by its self or does the HTML DB engine something in the background?
Will there be enhanced PDF support in future versions of HTML DB ?
Greetings,
Jochen

Hello,
Even though it's based on the report engine the xml feeds actually output page items and session items into the xml feed. By using these you can build some very robust/complex pdf's than just a report, it's just matter of using a different xslt.
There is no easy way to include the output of a custom region. But if you wanted to do some javascript hacking you could use javascript to splice in some custom xml,from plsql or wherever into the xml feed before it posts to fop server. When I have some time I'll post an example of this on HTML DB Studio.
HTML DB itself produces the xml it, it is just another output from our reporting engine.
XmlHttp is a javascript object it's used to pull the xml feed from the report engine without reloading a page and then posting the xml to the server to render the fop.
As for the servers used our howto is just written using the servers we have on hand, but any server that can run Apache Fop should work.
Thanks,
Carl
