Dynamic Region Title
Hello,
I'm attempting to create a generic survey like application that can have a number of possible questions and instructions. I would also like for the region title of certain regions to be dynamic, or rather equaling the value of some item on the page. I did some digging on Google and found that this was apparently possible in Apex 3, but I'm currently working in Apex 4. Does anyone know of a way to do this?
Thanks

(I changed my handle but it's still displaying the number !!!!)
Edited by: 965010 on Oct 12, 2012 7:31 AMI don't know when it is executed. I've just created page item P4_POSITION and made it as SQL query.
Actually, value in the P4_POSITION_ID item is from POSITION_ID in EMPLOYEE table, which contains primary key EMPLOYEE_ID and has foreign key - POSITION_ID,
POSITION_ID is a primary key of POSITION table, which contains POSITION_NAME.
What I made is I created link from page 3 using EMPLOYEE_ID to redirect to page 4. There are all items in the page 4, which are in the EMPLOYEE table. But I need to show POSITION_NAME from POSITION table. So I created page item P4_POSITION as I mentioned before.
Do I need to create dinamic action or process before handling Region title?

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.

How to change a region title based upon the input parameter?
Hi All,
I need to change the region's title dynamically based on the value of a select list in another region.
Can anyone help me in this?
Regards,
Sakthi.Hi,
You can use &P1_ITEM_NAME. (including the & and the .) in a region title - this string will be replaced by the value from the page item called P1_ITEM_NAME, so change the name to suit your page item

Page Template Popup with Dynamic Region TaskFlow
Hi.
I have a Page Template that is used extensively in my application to provide a consistent explorer panel containing tree links to various pages in the application. I'm trying now to enable users to edit configuration via a tree link. I would like to implement this as a Popup in the page template which contains a dynamic region that contains a bounded Task FLow (so I can control the transaction for the edit activity). I'm running into all manner of issues...
The Tree node is defined as follows:
<f:facet name="cognition_model_view.viewRepListVO">
<af:group id="pt_g4">
<af:commandImageLink id="pt_ot15" text="#{node.Viewname}"
action="callRouter"
actionListener="#{backingBeanScope.templateBacking.viewsGoActionListener}"
icon="/pics/folder-icon.png"
shortDesc="View: #{node.Viewdesc} | Filter: #{node.Filtername}"
partialSubmit="true"/>
<af:commandImageLink id="pt_ot16"
icon="/pics/edit1.png"
shortDesc="Edit View Config"
partialSubmit="true">
<af:setPropertyListener from="#{node.Appname}"
to="#{backingBeanScope.templateBacking.editViewAppName}"
type="action"/>
<af:setPropertyListener from="#{node.Viewname}"
to="#{backingBeanScope.templateBacking.editViewName}"
type="action"/>
<af:setPropertyListener to="#{backingBeanScope.templateBacking.editViewType}"
from="#{node.Sourceview}"
type="action"/>
<af:showPopupBehavior popupId="::pt_p_edView"
triggerType="click"/>
</af:commandImageLink>
</af:group>
</f:facet>The property listeners are to hold values that will be passed as parameters to the region's task flow.
The Popup is defined here:
<af:popup id="pt_p_edView" contentDelivery="lazyUncached"
popupCanceledListener="#{backingBeanScope.editPopupTFHandler.cancelPopup}"
popupFetchListener="#{backingBeanScope.editPopupTFHandler.showPopup}"
binding="#{backingBeanScope.editPopupTFHandler.editPopup}">
<af:panelWindow id="pt_pw1"
title="#{backingBeanScope.templateBacking.editViewName} - Edit View Configuration"
contentHeight="250" contentWidth="500" stretchChildren="first" modal="true">
<af:region value="#{bindings.dynamicRegion1.regionModel}" id="pt_r1"/>
</af:panelWindow>
</af:popup>The taskflow binding for the template is as follows:
<taskFlow id="dynamicRegion1" taskFlowId="${backingBeanScope.editPopupTFHandler.dynamicTaskFlowId}" xmlns="http://xmlns.oracle.com/adf/controller/binding">
<parameters>
<parameter id="inputApplicationName" value="#{backingBeanScope.templateBacking.editViewAppName}"/>
<parameter id="inputViewType" value="#{backingBeanScope.templateBacking.editViewType}"/>
<parameter id="inputViewName" value="#{backingBeanScope.templateBacking.editViewName}"/>
</parameters>
</taskFlow>The managed bean to hold the dynamic taskflowId (editPopupTFHandler) is referenced in the adfc-config.xml file at "backingBean" scope, and looks like this:
public class editPopupTFHandler {
private String taskFlowId = "/WEB-INF/editViews/editViewsTF.xml#editViewsTF";
private String emptyTaskFlowId = "";
private String currentTaskFlowId = taskFlowId;
private RichPopup editPopup;
public editViewPopupTFHandler() {
public String getDynamicTaskFlowId() {
return currentTaskFlowId;
public void cancelPopup(PopupCanceledEvent pce) {
currentTaskFlowId = emptyTaskFlowId;
public void showPopup (PopupFetchEvent popupFetchEvent) {
currentTaskFlowId = taskFlowId;
public void setEditPopup(RichPopup editPopup) {
this.editPopup = editPopup;
public RichPopup getEditPopup() {
return editPopup;
}If I don't define the bean at backingBean scope, I get a Target Unreachable error from any page using the template.
When I attempt to use the link to the popup, the popup displays but the region content does not. Is this a scoping issue?
Additionally, after pressing combinations of the 2 commandimagelink components, the first link stops submitting... this may be a side-effect of the region display though?
Again, as I'm quite new to ADF I don't know how to overcome or avoid these issues, or whether there is a better method to achieve an edit capability in a popup window from a page template.
Thanks for your help. I'm using JDeveloper 11.1.2.1.0 by the way.Hello again. I've managed to get the dynamic region displaying once I restarted JDeveloper and re-created the Region and backingBean. This has happened before - is JDeveloper known to get "confused" (like me!) in this way?
There are still issues though. The backingBean contains a PopupCanceledListener as follows:
public void cancelPopup(PopupCanceledEvent pce) {
System.out.println("CANCEL POPUP - Current Task FLow now empty");
currentTaskFlowId = emptyTaskFlowId; // where emptyTaskFlowId = ""
System.out.println("CANCEL currentTaskFlowId = " + currentTaskFlowId);
}Simple enough, but the dynamicTaskFlowId is not holding its cleared value. Subsequent call to the getter shows a non-null value...?
The Popup has the ContentDelivery="lazyUncached" and ChildCreation="deferred". The TaskFlow Binding has Refresh="default" and activation="deferred". With these property values the Popup is displays the correct value on its first use but then keeps that same value on any subsequent selection. I don't know whether this is because of the TaskFlow not correctly resetting or something else...
Can anyone help me please. This is beyond frustrating. The behaviour of these various property settings is not at all predictable for me... Thanks. -
I notice that when you create a report, you can only enter a static title but I want the title to be dynamic (based on SQL). What's the best way to do this AND have it displayed over the report table ? Create a "Display Only" item? Create a one line report that displays the title?

Refreshing icons to right of region title
Hi,
I have a number of icons to the right of my region title. These may well be for adding a new record, deleting all records etc.
The deleting all records icon is only shown if there are actually records shown in the report region, i.e. there are records to delete.
Using Skillbuilders modal page popup, I populate a record, and this uses the refresh region which means the region now shows the record. However, as discussed in numerous other discussions, the region title does not get refresh. I know I could use jQuery to change the region title, however I wish to effectively refresh the region title so that the delete all records icon appears if it was not already there.
So my senario is,
1. No records shown in report, so delete all records icon not displayed.
2. Use presses add record icon, and using modal page plugin, a new record is added.
3. Close modal page refreshes the region so that new record is displayed.
4. THIS IS THE PROBLEM - I need to refresh the region title as well so that the delete all records icon is now shown.
Any ideas?
Thanks,
Jeremy.Jezzer
Use the After Refresh event on the region to fire your dynamic action.
Using a javascript expression as when condition you can use a "add class" "remove class" to display or hide the delete icon.
Notice that the delete icon must always be rendered on the page to be able to show it after a region refresh.
I have done something similar in this demo. Change the number of rows in the regions to change the colour of the tabular form when it becomes below a threshold.
Nicolette -
I've read through numerous posts on how to use &MY_ITEM. in a region title to make it dynamic. I'm sure this is what I need but I have a little different situation and since I'm new to HTMLDB, I hope someone can assist.
I have 2 regions on the page in a parent/detail relationship. The 2nd region has a query that joins 2 tables one of which returns a column that is not updated by anything on the page, it is just PRODUCT_DESC (a product description). The product ID comes from the first region via a Select list with redirect item. The report region then dynamically runs its query and returns the needed information. What I would like to see is the PRODUCT_DESC put into the Region title so I don't have it listed as a separate column in the report output.
I've tried creating a hidden item and setting its value to the product_desc db column but that is not working. I imagine I may need some computation or process but those are still kind of foreign to me so I'm looking for some assistance.
Thanks,
BrianThanks for your time Scott
The code is as follows:
DECLARE
v_SelectStmnt VARCHAR2(2000);
v_app_offline VARCHAR2(1);
v_app_offline_message VARCHAR2(100);
BEGIN
v_SelectStmnt := 'SELECT NAME';
v_SelectStmnt := v_SelectStmnt||' , OCCUPATION';
v_SelectStmnt := v_SelectStmnt||' FROM TBL_EMPLOYEES';
wwv_flow.debug(v_SelectStmnt);
RETURN v_SelectStmnt;

WHEN OTHERS THEN
SELECT APP_OFFLINE
, APP_OFFLINE_MESSAGE
INTO v_app_offline

Can't view filtered VO properly in a dynamic region
Hi all,
I am using Jdeveloper 11.1.1.0
I have a view object (myVO) that has some view criterias (FilteredVO1, FilteredVO2, ecc.)
In myPage I have a dynamic region in which I can view different fragments. These fragments contain filtered data (FilteredVO1, FilteredVO2, ecc.), but I always see all the data (myVO)
If I run the application module, in FilteredVO1, FilteredVO2, ecc. I see the data properly (I see the filtered data, not all the data).
Also if I run a normal page (without fragments) with a panel tab for every FilteredVO, I see the filtered (and not all) data.
In myPageDef I have set the property "refresh" on "ifNeeded".
What's the problem? Any suggestions?
Thanks
AndreaHi Andrea,
Why do you want to set the refresh parameter? Is your task-flow has any parameters set..? Refresh parameter should be used only when you want the dynamic region to respond based on task-flow parameter. Otherwise, the dynamic region can automatically refresh based on different task-flow selection. So, precisely if you reset this param to default, it should work as expected provided these fragments uses different task-flows. See this document section [16.2 Creating ADF Dynamic Regions|http://download.oracle.com/docs/cd/E15051_01/web.1111/b31974/taskflows_regions.htm] for more info.

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>

How to escape special characters in a region title
I have created a drill down report where the second report is filtered by a value chosen in the first report. I am using &Pn_field. syntax to pass the name of the select value to the region title of the second report. Some of the returned values have a ':' in them and therefore the text does not print after the ':'. How do I escape the ':' in the region title?
regards
Paul PPaul,
I think your question is "How do I use f?p URL syntax to pass data values to a page where the data includes a colon?" (Please correct me if that's not the issue.) The answer is, you can't. Same with commas. HTML DB reserves those two characters for the f?p request syntax. You'll have to save the string into the item before the page branch. There is no restriction on what characters can be used in a region title, it's just HTML-formatted text, except that you must escape anything that looks like HTML unless you want the browser to treat it as HTML. There are restrictions, however, on what characters you can pass in URLs in general and you must take care to escape them properly, e.g., ?, &, whitespace.
And do speak up if I've missed the point.

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

Issue with refresh of task flow in dynamic region
Hi All,
I am using Jdeveloper version 11.1.1.6. In my fusion application I am facing an issue with the task flow refresh in the dynamic region. In my application, I have one task flow in which the side navigation command links are there and on the right side it has a dynamic region which is used to display the respective task flows on click of navigation links. Now two of the links actually call the same task flow in dynamic region but for different purpose. One for creating a record and another one for modifying the record. The default activity of that task flow has a page fragment that has couple of fields. One a drop down and another one a text field for searching the accounts against which the record is to be created or modified. On click of the navigation link, I set the task flow id to be displayed and refresh the dynamic region. Now the issue is with those two links which shows the same task flow. Let's say I searched for a record by putting some value in input text and then went on to modify flow using the modify navigation link. Then the value that I entered in search input text in the create flow stays and does not go away. I found out the cause for the issue and this is happening because of the immediate = true on the navigation command links. Now I cannot remove that because of the obvious reason that then it will start throwing exceptions for the mandatory fields when I am in middle of any flow. Is there any way to achieve it.
Please help as this is quite urgent. I can also upload the sample application if anyone needs it.
Regards
Ajaytry to put RefreshCondition in the pageDef file for that particular task Flow and try to make that condition to true only when you switch between edit or add. While switching, make sure that the mapped bean properties should also point to respective values i.e. either empty for new or holds some value for edit.
So, when ever the above condition returns true, task flow gets refreshes and it will holds only the current values not the old values.
i hope this will resolve your issue. -
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.

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?
