Error adding a dynamic region
I have a region I created that I loaded into the MDS, its location is: /oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN
I am trying to dynamically add it to a generic stackLayout region that I have in my page whose id is DynamicStackRN.
In the processRequest method I have the following code:
OAStackLayoutBean oaStack = (OAStackLayoutBean)webBean.findIndexedChildRecursive("DynamicStackRN");
OASubTabLayoutBean SiteTabsRN = (OASubTabLayoutBean)createWebBean(pageContext, oaStack, "/oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN", "SiteTabsRN");
oaStack.addIndexedChild(SiteTabsRN);
It never makes it to the third line, and on the second it forwards it to my page and I get an error at the top stating:
Could not create web bean, could not find item metadata Item Name: (/oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN); Region: (DynamicStackRN)
What am I doing wrong here?
Thanks,
Greg
Are you getting the error in jdeveloper or in the envrionment? If you are getting the error in the environment verify whether the region is present in the MDS repository. You can use the exec jdr_utils.printdocument('/oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN') for verifying. try adding the region to the project if you get the issue in Jdeveloper.

Adding a dynamic region/dataset after page loads
I am trying to dynamicaly add a new spry driven select box
after the page has loaded to allow n select boxes to be displayed.
My initial spry select is as below and works fine.
<div id="orgDiv">
<div id="orgDiv0" spry:region="dsOrg[0]">
<select id="selOrg0"
onchange='_addOrg(this.options[this.selectedIndex].value);'>
<option>--- Select --- </option>
<option spry:repeat="dsOrg[0]"
value="{CHILD_ID}">{STR_TEXT} </option>
</select>
</div>
</div>
The onchange for the select triggers a JS function to add a
new spry region div and select box to the page. All fine so far,
the only problem is I need to initialise the new spry region as it
has been inserted after the initial Spry.Data.initRegions();
Theinitial spry region renders correctly but the javascript
added node (second one) hasn't been initialised by spry:
<div id="orgDiv0" class="">
<select id="selOrg0"
onchange="_addOrg(this.options[this.selectedIndex].value);">
<option>--- Select --- </option>
<option value="2">Group PLC </option>
<option value="3">GSD </option>
<option value="4">Country </option>
</select>
</div>
<div id="orgDiv1" spry:region="dsOrg[1]">
<select id="selOrg1"
onchange="_addOrg(this.options[this.selectedIndex].value);">
<option>--- Select --- </option>
<option value="{CHILD_ID}"
spry:repeat="dsOrg[1]">{STR_TEXT} </option>
</select>
</div>
If I call Spry.Data.initRegions(); it just zaps the contents
of my dynamically added div:
<div id="orgDiv1" class=""/>
Not so good...
Is there a way to use the API to initialiase a new spry
region using a new dataset after the page has loaded?Are you getting the error in jdeveloper or in the envrionment? If you are getting the error in the environment verify whether the region is present in the MDS repository. You can use the exec jdr_utils.printdocument('/oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN') for verifying. try adding the region to the project if you get the issue in Jdeveloper.

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? -
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 !!!!!!
ThanksHi 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

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

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);
REGIONMAP.put(UIManager.Screen.EMPLOYEE_SEARCH,
"/WEB-INF/searchEmployees-flow.xml#searchEmployees-flow");
REGIONMAP.put(UIManager.Screen.DEPARTMENT_TREE,
"/WEB-INF/departmentTree-flow.xml#departmentTree-flow");
private UIManager _uiManager;
public TaskFlowId getDynamicTaskFlowId(){
return TaskFlowId.parse(
REGIONMAP.get(_uiManager.getSearchScreenFocus()));
public void setUiManager(UIManager _uiManager){
this._uiManager = _uiManager;
6.
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:

ThanksHi
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.

Client Side Error Message in Notification Region
Hi,
Is there any way I can display my client side validation in NOTIFICATION region.
My Scenario,
In my application, I have dynamic Apex Items (Generating Using APEX_ITEM API).
I have added client side validation (Javascript) when users clicks the button and I am showing my error message in alert window. (which is working fine). But now my customer wants to display the error message in Notification region instead of ALERT message.
Can anyone help me to solve this issue. Thanks in Advance..
Regards
Balaji SHi
Yup, just create a div in the page template in the right place to hold your messages and give it an id like...
<div id="noteArea"></div>Now in you javascript, rather than using alerts, you can use
var noteObj = document.getElementById('noteArea');
noteObj.innerHTML = 'my message with any HTML needed';Is this what you mean?
Cheers

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.

Edited by: lili5058 on Feb 7, 2009 5:06 PMHi,
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 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,
Stuart1) 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.

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

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

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? -
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8:49Well, 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. -
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?

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
