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 ?

Dynamic JDBC Credentials and using ADF Region ERROR

Hi,
I used solution by Steve Muench, Dynamic JDBC Credentials (for ADF Faces Rich Client)
(129. 11g Dynamic JDBC Credentials for Model 1, Struts, Trinidad, and ADF Faces Rich Client 11.1.1.0.0 06-AUG-2008), but it works not correct in case of using ADF Dynamic Region (or simply ADF Region).
I have added in ViewControllerJSFRichFaces a page (main.jspx) including ADF Dynamic Region consisting of 2 simple tasks flows. Action of the Login button, if login and password are correct, redirect to main.jspx
There are to cases.
1) Login and password are correct:
In this case all work fine.
2) Login and password are not correct:
It does not work. redirect to login.jspx does not occur as it is expected, but the following page (main.jspx) is loaded, herewith thrown exception: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.
I would be very grateful you for help.

Hi,
hard to say from your description if this is a bug or an implementation problem. Note that errors that occur in regions are not handled by the exception handler of the the parent page and require special handling within the region. In other words, if the problem is in the region then it needs to be handled in here. I think the right strategy here is to not show the region until a valid connection exist. Is the login performed from the parent page ?

Encountering error while working with Dynamic Regions.

Hi All,
I am a beginner in ADF and on a quest to learn ADF. Sometimes I am struggling in the process. Now, when I am working with Dynamic Regions, encountered problem below
Step 1 : Created a simple department TaskFlow with Department Form
Step 2: Created a Simple employee TaskFlow with Employee Details
Step 3: Created a Main page with oracle 2 column layout
Step 4 : Dragged and dropped department TaskFlow on to main page second facet as Dyanmic region . Created a bean as RegionBean
Step 5 : Dragged and dropped department TaskFlow as Command Link on the first facet
Step 6 : Dragged and dropped employee TaskFlow as Command Link on the first facet
The page runs and shows department information when it renders. But when I click on employees command link, at first it shows employees table with no data and says "ACCESS DENIED ". Then if I click on either department or employee command link, it errors out with below info

Please help me !!!!!!
Thanks

Hi Shay Shmeltzer ,
Thanks for your quick reply. Below is response for your queries
What scope did you specify for the bean? View Scope
Also which browser are you using? Firefox
Thanks for the link. I started to build dynamic region after taking a look at the video
What else do you think might be the issue
Thanks

Error in Dynamic Regions load

Hi! I'm new in ADF. My problem is:
I use a Tree like a menu. When we click on tree node, on the right of the page will display form with some Data Control ( I use Dynamic Regions to contain form with Parameter input text and table).
1. When I click on tree node, the Dynamic Regions display form and auto fetching data in table without Parameter input and get error.
2. If Dynamic Region has some button. When I click on it, Region will load back to default region and don't show data to table. How to pass it?
Please help me, thanks in advance!

Hi, actually your question doesn't provide lot of hook points 1) I understand the task flow you load in the region does not take a parameter. I don't know though what the error is because you don't tell us anything about it. I assume however that the bean you use to switch between regions is in request or backing bean scope. The scope of the bean should be in view scope 2) This sound like the same problem. The bean you use to switch between regions is in request or backing bean scope. Change it to view scope and you should be okay Ps.: Make sure the bean is really only used to switch between regions and does not hold JSF component binding references Frank

Issue while deploying dynamic region to stand alone server

Hi,
In my application there is one page I have panel splitter, where i have drag and dropped menu-taskflow as regionModel, and created dynamic region on second facet panel.
<af:region value="#{bindings.menutaskflow1.regionModel}" id="r1"/>
<af:region value="#{bindings.dynamicRegion4.regionModel}" id="r2"/>
I have created application level class to handle dynamic region loading.
This settings are working fine when i run application with integrated web logic server, When I deployed my application to stand alone server, its giving me exception as
java.lang.IllegalStateException: The expression "#{bindings.menutaskflow1.regionModel}" (that was specified for the RegionModel "value" attribute of the region component with id "r1") evaluated to null.
This is typically due to an error in the configuration of the objects referenced by this expression.
If it helps, the expression "#{bindings.menutaskflow1}" evaluates to "null".
If it helps, the expression "#{bindings}" evaluates to "null". Now using an empty RegionModel instead.

Problem with bounded task flow: binding lost?

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 in Popup - clientListener problem?

Hello,
I'm working in Jdeveloper 11.1.1.2, following the popup/region pattern found at: http://www.oracle.com/technology/products/adf/patterns/11/popupregionpattern.pdf to have a dynamic region in a popup. I already have a working implementation on one of my pages, but the exact same implementation on another page is giving me issues. Whenever I add an af:clientListener component to my popup, the table in the same panelCollection stops rendering its rows. The column headers display, but there's no text of any type in the rows. If I delete the af:clientListener, my page works perfectly.
Here's my popup code thus far:
<af:popup id="awdPU" contentDelivery="lazyUncached"
launcherVar="source" eventContext="launcher">
<af:setPropertyListener from="#{source.attributes.saId}"
to="#{pageFlowScope.currentSaId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.saId}"
to="#{pageFlowScope.currentSchlrId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.appId}"
to="#{pageFlowScope.currentAppId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.aidYear}"
to="#{pageFlowScope.currentAidYearId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.theAction}"
to="#{pageFlowScope.currentAction}"
type="popupFetch"/>
<af:setPropertyListener from="#{viewScope.popupDynamicRegionBean.popupTaskFlowId}"
to="#{viewScope.popupDynamicRegionBean.dynamicTaskFlowId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.orgId}"
to="#{pageFlowScope.currentOrgId}"
type="popupFetch"/>
<af:panelWindow id="pw1" title="Awarding">
<af:region value="#{bindings.dynamicRegion1.regionModel}"
id="dynam1"
regionNavigationListener="#{viewScope.popupDynamicRegionBean.regionNavigated}"/>
</af:panelWindow>
<af:serverListener type="serverPopupClosed"
method="#{viewScope.popupDynamicRegionBean.swapEmptyTaskFlow}"/>
<af:clientListener method="popupClosedListener"
type="popupClosed"/>
</af:popup>
and here is my working, completed dynamic region + popup code:
<af:popup id="awdPU" contentDelivery="lazyUncached" launcherVar="source"
eventContext="launcher">
<af:panelWindow id="window" title="Awarding" modal="true" closeIconVisible="false">
<af:region value="#{bindings.dynamicRegion1.regionModel}" id="dynam1"
regionNavigationListener="#{viewScope.popupDynamicRegionBean.regionNavigated}"
inlineStyle="background-color:transparent;"/>
</af:panelWindow>
<af:setPropertyListener from="#{viewScope.popupDynamicRegionBean.popupTaskFlowId}"
to="#{viewScope.popupDynamicRegionBean.dynamicTaskFlowId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.saId}" to="#{pageFlowScope.currentSaId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.appId}" to="#{pageFlowScope.currentAppId}"
type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.aidYear}"
to="#{pageFlowScope.currentAidYear}" type="popupFetch"/>
<af:setPropertyListener from="#{source.attributes.theAction}"
to="#{pageFlowScope.currentAction}" type="popupFetch"/>
<af:clientListener method="popupClosedListener" type="popupClosed"/>
<af:serverListener type="serverPopupClosed"
method="#{viewScope.popupDynamicRegionBean.swapEmptyTaskFlow}"/>
<af:clientAttribute name="action" value="makeAward"/>
<af:clientListener method="adjustPopupSize" type="popupOpening"/>
</af:popup>
Does anyone know of any reason a client listener would have this kind of impact on my page? I've tried other types/methods and it just seems like if an af:clientListener is there, it won't work.
Thanks!

Hi,
I came across this type of problem. what the javascript method u r calling it may contain some errors or if the clientListner not able to find the method which u r calling in the jspx file that will behave like that only.
keep one alert begining of the script method(popupClosedListener) and check it whether it is calling or not. Better related serverListner should be after the ClientListner.

Input Date does not work correctly In dynamic region

Hello everyone.
I created a view with a dynamic region. When switch to a region with Input Date components, if I click the "Choose Date" button, this region will exit to default region without any error message.
The component works well in default region but not in regions switched by Link.
I tried it in a completely new application and i am sure there is no any problem except the component and the region themselves.
SO, if someone tied doing this and know what cause it and how to fix it?
Edited by: 1007000 on 2013-5-20 下午8:49

Well, i find out the problem. I set the managed bean of the region backing scope, and Input Date is a server-side component. So the taskflow id will lost when i click the Choose Date button.
change the scope to pageflow, and it works.

Dynamic Region Issues

Jdev 11.1.1.5 - JDK 1.6_31
I have put a dynamic region on a page with 4 taskflows defined as the regions. Each taskflow is a train.
I have a bean that controls the loading (the default bean) with a load for each screen.. ie public .. myRegion1, etc... in addition to the getDynamicTF that is created by default.
public TaskFlowId getDynamicTaskFlowId() {
return TaskFlowId.parse(taskFlowId);
public String myjobFlow() {
taskFlowId = "/WEB-INF/myJobstaskFlowCall.xml#myJobstaskFlowCall";
return null;
Everything works fine - the pages load and all is OK - until I select a tab in one of the regions.
This will cause the generation of the event to get the taskflow from the bean. (getDynamicTaskFlowId)
because the bean is backing scoped - it does not know the current taskflow (lost when the bean is destroyed)
I tried to change the scope - but I get a controller error saying the backingBeanScope.DynamicRegionBean cannot be found!
can anyone tell me the location of the controller file - or how to change the scope - or how to get around this issue.

Hi,
instead of using backingBeanScope use viewScope..
and change expression wherever necessary like
in page and more important in pageDef file..
like
from
backingBeanScope.bean to viewScope.bean
Hope this helps..

Using facelets and javascript in dynamic regions

Hello
I'm using JDeveloper 11g 11.1.1.4.0.
In the JDeveloper's documentation I found that there is the best parctice to use facelets.
Now, I have next problem.
I use dynamic region iside xhtml (facelets) page. Inside that dynamic region there is a view (jsff).
The problem is that I can't use any custom JavaScript in that jsff.
I tried next thing:
            <trh:script id="trhs1">
                <af:resource type="javascript">
                  testm = function (event) {
                  alert('qqq');
                </af:resource>
           </trh:script>
<af:clientListener method="testm" type="dblClick"/>If that task-flow is placed inside jspx (not facelets) page, then all works.
If that task-flow is placed inside xhtm (facelets) page, I have an error from browser that javascript's 'testm' method is not defined.
I checked source code of the result html-page, and my javascript code really doesn't exists there.
I can fix it by moving javascript code from the taskflow's jsff to surrounding xhtml page or using jspx page, but, maybe, there is another solution?

Thank for replay, Shay
I found that in Web User Interface Developer's Guide for Oracle ADF, 2 Getting Started with ADF Faces, Section 2.4, "Creating a View Page":
Best Practice: Use Facelets to take advantage of the following:
The Facelets layer was created specifically for JSF, which results in reduced overhead and improved performance during tag compilation and execution.
Facelets is considered the primary view definition technology in JSF 2.0.
Some future performance enhancements will only be available with Facelets
Now I have facelets page with dynamic region, it works.
I've decided to use facelets because of the forthcoming JDeveloper with JSF 2.0 and for performance improvements described above.
Do you think it's better to use jspx?
I have not found any limitations for facelets in Web User Interface Developer's Guide for Oracle ADF and Fusion Developer's Guide for Oracle ADF

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";
private String AdminTaskFlowId = "/WEB-INF/Admin-flow.xml#Admin-flow";
private String currentTF = "home";
public SearchFlight() {
public TaskFlowId getDynamicTaskFlowId() {
if (this.getCurrentTF().equalsIgnoreCase("home"))
return TaskFlowId.parse(SearchtaskFlowId);
else
return TaskFlowId.parse(AdminTaskFlowId);
public void setCurrentTF(String currentTF) {
this.currentTF = currentTF;
public String getCurrentTF() {
return currentTF;
When i click the admin link in home.jspx the admin_login.jsff page is opening.After entering the credentials and clicking login button it is going to the search page of search task-flow not to the welcome.jsff.
The admin_login.jsff is

Dynamic region table with binding problem

Hi. I'm using jdev 11.1.1.3 and ADF full stack.
My app uses single page approach with ADF libraries and a dynamic region to show content. Main page includes a menu bar which is created on session startup and is used to load task flows from libraries.
I have a class to provide some table functionality like CRUD, multi-row delete, etc and I need to reuse with every table included in libraries.
To do this, in main web app I have a managed bean to hold table binding and to provide this common functions to all fragments if needed.
I think it must be in request scope as fragment changes.
Here's the problem: when I navigate to a fragment which contains a table with binding, first time goes well,
but next time table, when fragment changes,new table displays without header or without data.
If I go to another fragment without binding and return to a fragment with problem, it displays well. With fragments without table binding, it works OK.
I've tried changing scope of this 'general' managed bean, but same thing. If I put a bean for each fragment, it works OK.
So, how can I 'share' this managed bean through every table? Any suggestions? is it possible?
Please, help me ....
Thanks,
DEMR.

I am seeing a similar problem in my app. I have a main menu that drives a dynamic region. If the task flow that gets displayed in the dynamic region also contains a dynamic region, when the inner dynamic region is refreshed to point to a second task flow, the page does not render correctly. The errors we have seen include data in tables not being displayed in some cases, and PPR errors in other cases. In both cases, if the inner dynamic region is replaced (by a single bounded task flow with navigation logic in a template, for example) the errors go away. There appears to be issues involved with including a dynamic region within a dynamic region.
Have you made any progress on solving your issue?

ADF dynamic region - Browser is blank

Hi All,
I am following a hands-on practice in Oracle JDeveloper 11g Handbook. I have created two bounded task flows named "searchEmployee-flow.xml" and "departmentTee-flow.xml". I want to call these task flows from af:commandLink in a dynamic region. In the Choose Managed Bean for Dynamic Scope dialog I have provided following steps:
1. Click New (green “+”) to add a managed bean. Set Bean Name as “searchScreenBB,” Class Name as “SearchScreenBean,” and Package as “tuhra.view.backing.” Click OK. Click OK.
2. I wrote UIManager class to switch page fragments:
package tuhra.view;
public class UIManager implements Serializable
public enum Screen {EMPLOYEE_SEARCH, DEPARTMENT_TREE}
private Screen searchScreenFocus = Screen.EMPLOYEESEARCH;
public void setSearchScreenFocus(String focus) {
this._searchScreenFocus = Screen.valueOf(focus);
public void setSearchScreenFocus(UIManager.Screen focus){
this._searchScreenFocus = focus;
public UIManager.Screen getSearchScreenFocus() {
return _searchScreenFocus;
3.
I opened adfc-config (under Page Flows in the Application Navigator). On the Overview tab, selected Managed Beans and added a bean (using the green “+”) and fill in Name as “uiState,” Class as “tuhra.view.UIManager,” and Scope as “session.”
4.
Updated SearchScreenBean.java to read as in the following code listing (without the line numbers).
package tuhra.view.backing;
import java.util.HashMap;
import oracle.adf.controller.TaskFlowId;
import tuhra.view.UIManager;
public class SearchScreenBean {
private static final HashMap<UIManager.Screen,String> REGIONMAP;
static {
REGIONMAP = new HashMap<UIManager.Screen,String>(2);

To have JSF inject the UI manager value, I switched back to the adfc-config.xml editor and locate the Managed Beans area on the Overview tab and performed folliwing steps as told in book:
6.1. Select the searchScreenBB bean and then click Add (green “+”) in the Managed Properties: searchScreenBB table. Set the managed property Name to “uiManager” (to match the setUiManager() method in the bean), the Class to tuhra.view.UIManager, and the Value to “#{uiState}.”
6.2. Now that the logic to switch the screens is in place, you can define how the UI will activate the change in searchScreenFocus values. You could of course use a custom method in SearchScreenBean, but using a af:setPropertyListener is simpler. In the employeeSearch.jspx file, locate the af:commandLink that surrounds the “Search for Employees” image.
6.3. Drop into the af:commandLink a Set Property Listener (Operations panel). Set From as “#{'EMPLOYEE_SEARCH'},” To as “#{uiState.searchScreenFocus},” and Type as “action.” Click OK.
6.4. Repeat the preceding step for the “View by Department” link. This time, fill in From as “#{'DEPARTMENT_TREE'}.”
6.5. Click Save All.
When I run the form as directed, It is blank and is giving following error messages:

Hi
This error occurs on account of the scope of backing bean Taskflow id not set up correctly and taskflow id leads to null pointer exception.
Open EmplloyeeSearch.jspx - go to bindings. click taskflow - dynamic region in binding. Set the property as follows:
#{backingBeanScope.searchScreenBB.dynamicTaskFlowId}
This should resolve the issue.

Dynamic Regions w/Train Component

I'm working on a web app (JDeveloper 11g) where one page has a dynamic reqion with a task flow associated with it that sets the fragment for the view. Most of the fragments for this region use a page template with a train component. Navigation using the train component mostly works fine- the fragment is replaced by a new fragment each time a train link is clicked.
However, one fragment contains another dynamic region. I tried to set the scope of the bean managing this region to viewScope, but I get a popup message in the browser "viewScope.myManagedClass.dynamicTaskFlowId" is invalid" when I click the train component link for the fragment. I get a similar error if I set the scope of the bean to session or pageFlow. Only when I set the scope to backingBean or None do I avoid the error message.
But then another problem occurs. One of the fragments in the flow for the inner region has a panelAccordion with several showDetailItems consisting of selectManyCheckboxes. The panelAccordion doesn't list anything, and locks up if I try to open or close any showDetailItem. This behavior is similar to when the scope for the bean managing the flow is not set to viewScope or higher.
In stepping through the code, I noticed that the outer region's flow code runs after the inner region's trigger event code that sets the inner region's taskFlowId, but before the inner region's flow code, so the inner region's taskFlowId setting is lost. I tried throwing the setting into session context and retrieving it, and that almost works. If I actually select any of the selectManyCheckboxes, they are lost once I move to a different fragment in the inner region.
Does anybody have any ideas on how to I get this page working, alternatives to the approach I'm taking, settings I should check, and/or any reference material I could consult?
Thanks in advance!

Hi,
However, one fragment contains another dynamic region. I tried to set the scope of the bean managing this region to viewScope, but I get a popup message in the browser "viewScope.myManagedClass.dynamicTaskFlowId" is invalid" when I click the train component link for the fragment.
Is the managed bean defined in the metadata definition of the bounded taskflow that you load ? Note that bounded task flows are only initializing their managed beans when they are loaded. If you define the managed bean in the parent bounded task flow then the viewScope also is the one of the parent flow. Appears as if this is the problem you describe
