Panel Tabbed within dynamic region

Hi Every body
I have 3 dynamic region each region has a panel Tabbed when run the page the first region work fine when navigate between tabs (af:showDetailItem) , the second region it does't work when navigate between tabs it's like frozen just first tab (af:showDetailItem) open and the same thing with the third region ?
any help?!
I'm using JDev 11.1.1.3.0

Hi,
the managed bean that holds the dynamic region TaskFlowId is in backing bean scope by default. Change the bean scope to viewScope and also change all the EL references to the bean accordingly (on the page and the task flow binding in the PageDef file)

How To create new Tabs in Dynamic Region

Hi to All,
Im a newbie please help me .Consider I have a two buttons or links on left side of Panel splitter and on right side im having Region/Dynamic Region.My aim is by clicking first button a new Tab should be appeared inside which a bounded task flow fragments get launched dynamically in the Region or Dynamic Region.And by clicking the second button a new second Tab next to the previous Tab should be displayed with another different fragments gets launched/displayed inside the second Tab.
Please give me tutorial links or suggestions to fullfill this...Thanks in Advance
Regards,
Navin

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.

Panel Tabbed with regions

Hi
I have Panel Tabbed with two items inside - both contains regions inside (static - not dynamic).
        <af:panelTabbed id="pt1" partialTriggers="t1">
          <af:showDetailItem text="Item 1" id="s1">
            <af:region value="#{bindings.emp.regionModel}" id="r1"/>
          </af:showDetailItem>
          <af:showDetailItem text="Item 2" id="s2">
            <af:region value="#{bindings.dept.regionModel}" id="r2"/>
          </af:showDetailItem>
        </af:panelTabbed>Logging initializers and finelizers for task flows inside these regions I noticed that both are triggered when I enter on the page with Panel Tabbed. Only task flow on selected item should be loaded - em I right ? Is there any property to set "loading on demand" regions in Panel Tabbed ?
Kuba

Hi,
depends on the JDeveloper version you are on. For example, you can set a task flow binding (in pageDef) to deferred loading in which case it does what you want it to do. Early JDeveloper 11g R1 releases did not have this feature, in which case the behavior is as you see it. So you may need to check your JDeveloper version, and if it is an upgraded JDeveloper 11g application, check the deferred setting on the task flow binding

Best approach -Tabs based ADF Tree left side navigation with Dynamic Regions with out UI Shell

Hi,
Somebody can help for the best approach to implement the following requirement.
Req: When the user select the ADF Tree left side navigation menu, each menu will open as multiple tabs(Dynamic Tabs) in right side content area with out UI Shell Template.
I completed the
Step-1: From the Model project, I can able to render ADF Tree in the using view and view links. I can get the adf tree which is having 3 menu items. Each menu item having 2 sub menu's.
I took each menu item as one(1) taskflow, each taskflow will have two(2) fragments.
Total I have 3 task flows as Menu Items and 6 fragments for sub menu's.
Step-2: My question is How do I implement Tab based the ADF tree navigation (left side area to dynamic regions in content area) through dynamic regions? Please provide the steps in view layers.

Than ks for your response.
This is working fine for ADF Tree navigation with dynamic regions if the taskflow having only one fragment. if the taskflow having more than one fragments, this will not work. The following conditions are always satisfies one page fragment of either "employees" or "departments" task flow. If the "employees" task flow have 2 page fragments, it's not work even you pass parameters through routers.
public TaskFlowId getDynamicTaskFlowId() {
if (currentTaskFlowID == null ||
currentTaskFlowID.equalsIgnoreCase(“employees”)) {
return TaskFlowId.parse(employeetaskFlowId);
if (currentTaskFlowID != null &&
currentTaskFlowID.equalsIgnoreCase(“departments”)) {
return TaskFlowId.parse(departmetaskFlowId);
return TaskFlowId.parse(employeetaskFlowId);
My question is "Same use case with Dynamic Tabs" when the user click on any adf tree node.

Region in panel tabbed throws exception

hi!
I have a Jsff page with a panel tabbed having two showDetailItem and each showDetailItem has region. Both region activation property is set to Conditional with corresponding EL for Active attribute. The region in first tab is loaded succesfully, and same thing with the region in the second tab. But when I get back to the first tab I got this Exception
<RegistrationConfigurator><handleError> Server Exception during PPR, #1
java.lang.NullPointerException
     at oracle.adfinternal.view.faces.taglib.region.IncludeTag$RelocatedFacet.restoreFacet(IncludeTag.java:900)

     at oracle.adfinternal.view.faces.taglib.region.DynamicIncludeTag.doStartTag(DynamicIncludeTag.java:109)
All the backing beans of the regions are in request scope.

I had isolated the problem, it is not the region.. it's the pageTemplate so I post another thread for this.
Cannot use the same page template in panel tabbed

Panel Tabbed Inter-Region Communication - jdev 11.1.2.3

Hello:
I have a page with panel tabbed. In each showDetailItem (TAB) there is a bounded task flow (BTF from ADFLib) that needs to receive employeeID.
The employeeID is used as a bind variable for each VO query shown in the tab. When the user clicks on a new tab, I want to receive the employeeID
in the BTF and set the bind variable in the VO and then let the BTF execute the query so when the tab doscloses it shows the VO results based on the new employeeID.
Note: it is the clicking of a tab that should accept the employeeID and set the bind variable so when the VO executes it correctly displays the results of the query in the newly opened tab. Currently I am using BTF Input Parameters to get the employeeID, which works ok. But how do I set the VO bind variable to the new employeeID before the BTF executes? Note: I know how to set VO bind variables with:
getParmsMap().put(bindVar, employeeID)
which I tried setting in the BTF Initializer. But this does not work. It seems ADF is processing somehow and does not like when I try to process my query within it's normal ADF lifecycle of disclosing the tab.
So when a new tab is selected to be opened, I need to accept the new employeeID, set the bind variables of the VO, before the ADF lifecycle kicks in to display the newly opened tab. When the tab is finally displayed by ADF, the VO query results should show the results based on the new employeeID.
How can I make this happen?
Any articles or sample code would be greatly appreciated.
Thanks much.

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.

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
Andrea

Hi 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.

.js update of spry accordion panel tab data for countdown functionality

Hi,
First off I must say I really love the work done on CS3 and
the Spry Framework - loads of examples and nicely implemented!
Questions in a nutshell:
Can I change spry generated data on the fly so I can run a
.js counter function to dynamically update accordion panel data?
What event do I look for to fire a .js init function to see my new
spry widget (onPostLoad isn't working for me, but I'm a newbie!)?
* spry accordion
* {expire} dataset data is SQL DATETIME
* js countdown function CD_Init() searches DOM for specific
element IDs 'countdownN' and uses innerHTML to update counter at
specific interval
* observer onPostLoad seems to be calling CD_Init before
accordion DOM is loaded.
Verbose questions:
I am trying to tweek the output of a Spry Acoordion and
wanted to add a third party js counter to my accordion panel tab
and am having a bit of difficulty. The js code uses an innerHTML
statement to keep the counter going and supports multiple counters
(which I need to use one counter per tab). I build the multiple
counter id from the ds_RowID field which is where the parent div
element where the js changes the innerHTML. Can I do this? The .js
searches for elements w/ an ID of "countdownN", N = instance # and
a date format of '2007-09-08 00:00:00 GMT+00:00' and updates the
div's text with the countdown time. My {expire} record below is an
SQL DATETIME which is the correct format for this countdown.js
function (with the GMT-05:00 appended).
The relavant code is:
<div id="specialDisplay" spry:region="dsSpecials">
<h3>Click on a special below from our <em>LIVE
FEED</em> to see all the up-to-the-moment
exciting packages available!</h3>
<div id="AccordionSpecials" class="Accordion">
<div class="AccordionPanel" spry:repeat="dsSpecials">
<div class="AccordionPanelTab"
onclick="dsSpecials.setCurrentRowNumber('{dsSpecials::ds_RowID}')"
spry:hover="AccordionPanelLabelHover"><?php echo '<div
id="countdown' .'{ds_RowID}'. '">';?>{expire}
GMT-05:00</div>{dsSpecials::name}</div> 
<div class="AccordionPanelContent">
<div spry:state="loading"><img
src="./i/ajax-loader.gif"/></div> 
<div spry:state="error"><span spry:content="Error
loading data..."></span></div> 
<div id="details" spry:state="ready"
spry:content="{detail}"></div> 
</div> 
</div> 
<script type="text/javascript">

</script>
</div> 
</div> 
I got the nice countdown.js script from
http://andrewu.co.uk/clj/countdown/
which allows N # of counters/page. I have updated this code to
start checking for a zero based index that I generate utilizing the
spry ds_RowID.
I have added an observer to run the countdown's
initialization function (to hopefully find all the "countdownN"
element instances) under my dataset declarations:
var observer = { onPostUpdate: function(notifier, data) {
CD_Init() ; } };
Spry.Data.Region.addObserver("AccordionSpecials", observer);
Also tried to add the observer to a div surrounding the
according w/ the "spry:region" specified.
But, alas, I see the correct expire instance in my tab, but
it looks like the counter is only firing before the actual data is
loaded (i.e. I used FF's webdeveloper and set a break on the
CD_Init function and it's breaking before the actual accordion is
there - I see the dataset placeholders in my window for the
accordion. When I continue, the accordion is generated, but my
countdown isn't working because it looks to be firing before the
DOM is updated w/ the accordion elements.
Sorry for the long speil; I'm really a .js neophyte and just
starting w/ spry - so I'm not even sure if I can/should change the
HTML generated from spry. If not, is there anyway that I can have a
countdown timer for each accordion's tab panel's associated
{expire} data field? Any ideas and suggestions are greatly
appreciated!!
Thank you also for this forum - some great gems for
development here!

Sorry - the previous post is way too long.
Is it possible to tie in a javascript update function (a
counter update) to an element generated by a spry widget (a dataset
value that generates spry accordion tab text) so that the accordion
tab gets updated by the javascript function running under a
setinterval?
I've tried firing the javascript init function with an
observer on the accordion's onPostUpdate event, but it's getting
fired before the spry data is loaded. Is this something that's
possible? Sorry for my lack of javascript expertise! Relying on the
real experts here!
Thanks for any advice/pointers.

Panel tabbed is not working in the page fragments used in a bounded task fl

Hi,
I tried creating a simple page fragment with a panel tabbed as below
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
xmlns:f="http://java.sun.com/jsf/core">
<af:panelStretchLayout id="psl1">
<f:facet name="center">
<af:panelTabbed id="pt1">
<af:showDetailItem text="showDetailItem 1" id="sdi1"/>
<af:showDetailItem text="showDetailItem 2" id="sdi2"/>
<af:showDetailItem text="showDetailItem 3" id="sdi3"/>
</af:panelTabbed>

</f:facet>
</af:panelStretchLayout>
</jsp:root>
Then in an unbounded task flow, I added the bounded task flow which is just created above. when I run this page, the page is loaded but the tabs doesn't switch. When I click on the other tabs, it doesnt change, it is always active only in the first tab.
Is this a bug in adf, or am I missing something?
Can someone please help?
Thanks,
Sudarsan M

Hi Vinod,
Thanks for responding.
I want a page fragment with tabbedPanel to be loaded in my dynamic region. As I am facing this issue, I tried very simple example of creating a page fragment with a tabbedPanel of 3 tabs.
1. added this page fragment in an bounded task flow.
2. In the unbounded task flow(adfc-config.xml) added a view with the some jspx page and then added the bounded task flow created above as a static region in this jspx page.
3. When I run this view, I can see the page loaded with all the tabs in the page frament.
4. By default the first tab is selected, but when I tried to click on the other tabs, there is no response. It still stays in the first tab only.
Thanks,
Sudan

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:

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 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 ?

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?

Implement commit,rollback,cancel popup when swapping task in dynamic region

Hello,
I have been trying to implement this functionality when I swap task flows in a dynamic region....
A popup/dialog to be displayed with the following options (assuming there are changes to be saved on the task flow being swapped out)
Commit - save the changes on the the outgoing task flow and continue to bring in the new task flow
Rollback - cancel the changes on the the outgoing task flow and continue to bring in the new task flow
Cancel - remain on the outgoing task flow and do not bring in the new task flow
If i click on a button within the outgoing task flow, it is possible to determine the condition of the view object, determine if there are pending changes and display such a dialog, the problem is if that the navigation within the dynamic region is being performed from outside the region, we are advised against using task flow return activities when using bounded task flows within regions ( section 17.1.8 of fusion dev guide for 11.1.1.1.0 ) so the only thing i can think of is building a finalizer routine for the task flow. While this does get executed when the task flow is swapped out... how can i display the dialog from there, and stop execution of the finalizer and return to the original task flow if ultimately i want to cancel.
Any ideas? other solutions?
Thanks.

Thanks for the reply Richard,
I think this will probably be an important feature for anyone using the single page model, unless that model is not being encouraged/being discouraged. Unfortunately I'm not aware of the "How-to" you mentioned, but I would dearly LOVE to be. The project I am working on is in a relatively early stage, and this would be the time to put things in extension libraries, templates and the like. Especially if there is no official line on when a formal fix might be available, the plans not being firm and all...
But thanks for the reply none the less... I'd still appreciate any further information if anyone has some form of solution.
Cheers
