Error when launching bounded task flows in dynamic tabs from UI Shell templ

Hello,
could you tell me what is wrong with launching task flows in new tabs?
I am using the UI Shell template, the task flow is bounded with one simple page (I tried with both fragments jspf and pages jsp)
The execption is the following:
java.lang.ClassCastException: javax.faces.component.UIViewRoot cannot be cast to oracle.adf.view.rich.component.fragment.UIXRegion
Here's the code I am using to launch the bounded task flow:
private void launchActivity(String title, String taskflowId, // taskflow is something like "/WEB-INF/mytask_flow.xml"
boolean newTab) {
try {
if (newTab) {
TabContext.getCurrentInstance().addTab(title, taskflowId);
} else {
TabContext.getCurrentInstance().addOrSelectTab(title,
taskflowId);
} catch (TabContext.TabOverflowException toe) {
toe.handleDefault();
Root cause of ServletException.
java.lang.ClassCastException: javax.faces.component.UIViewRoot cannot be cast to oracle.adf.view.rich.component.fragment.UIXRegion

Hi Pramod,
Have you tried setting the Transaction attributes of your task-flow? Open up your task flow definition then go to Overview Tab. Try changing the appropriate attributes like setting the transaction as "Always Begin New Transaction" and/or unchecking the "Share data controls with calling task- flow". Try to mix settings and find the one that suit your needs.

11gR2 error: call a bounded task flow with method call as default activity

hi all,
We migrated several applications to the JDev 11g R2.
There are 2 applications that contain a bounded task flow where we define Method Call as default activity.
We need invoke specific actions before opening the page.
They run well with 11gR1.
But with *11G R2*, I can’t call directly this task flow with the following URL:
http://127.0.0.1:7101/MyAPP/faces/adf.task-flow?adf.tfId=my-flow-def&adf.tfDoc=/WEB-INF/flows/my-flow-def.xml
Message:
*<SecurityUtils><invokeURLAllowed> ADFc : impossible to call directly the task flow '/WEB-INF/flows/ my-flow-def.xml #my-flow-def' with the help of URL*
(original message: <SecurityUtils><invokeURLAllowed> ADFc : impossible d'appeler directement le flux de tâches '/WEB-INF/flows/ my-flow-def.xml #my-flow-def' à l'aide de l'URL.)
Any idea?
Thanks for you help

Hi,
Have a look at the task flow properties, in PatchSet1, a new feature "invokeURLAllowed" is added that prevents bounded task flows from being URL accessible for security reasons. You can swithc this feature on and off
Frank
Ps.: I though that bounded task flows that you call from a URL generally needed to have a viewActivity as the default activity

Calling a bounded task flow (that uses fragments) from another application

Hello,
I'm currently having difficulties calling a task flow located inside another application.
I have application Console which is my main application in which I would like to run other applications within. Inside this Console I have it divided into splitter windows and inside them I have regions. My goal is to be able to call a task flow from another application inside one of these regions but so far I'm having no luck.
My first problem occurred when I created a 'local' task flow to make a call to another application's task flow. When I set the properties to the task flow call, it gave me an error that it could not find the .XML file for that task flow when I ran the Console application. I then proceeded to copy that .XML from the remote application into the Console's WEB-INF directory and I seemed to get a bit farther. The error I get now is saying that I cannot run a task-flow that uses fragments. It's essentially trying to run that task flow as an entirely new page instead of inside the region that it's bound to. It's NOT a dynamic region (although that's the end goal here). So I then changed the other application's task flow to simply display an entire page rather than fragments inside a region and voila, it works..... kind of.
To recap how I was able to call another application's task flow inside the Console:
- I had to manually copy the task flow xml file into the Console WEB-INF directory
- I had to change the task flow so that it didn't use fragments
- I have called the task flow but I lose my console page entirely, no more regions or splitters so I'm back to square one.
If anybody has any suggestions, hints, tips or anything, send them this way and I will be forever greateful.
Thanks,
Mark

Thanks for your response Frank.
Unfortunately the problem seems to be greater than that. I've been able to package task-flows into a jar library and tried importing them that way with no luck.
I'm simple trying to call an external task-flow to run inside a region which is inside a splitter panel that I call my console.
Any other ideas ?

Swap task flow in dynamic region from menuitem in menubar

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

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

UI Shell - how to allow ADF Library Bounded Task Flow to close itself

Hi Richard
Further to my other post, we're having lots of fun with the UI Shell, it's making mockups very easy.
Question for you though based around the functionality defined in the UI Shell whitepaper. Say we've created our UI Shell application, and rather than wanting to create the bounded task flows in the app (ie.first, second, third), we create them as standalone bounded task flows deployed to ADF Libraries, and imported into our app separately.
In the UI Shell examples bounded task flows are opened & closed via the UI Shell's own components (say the navigation page items or toolbar buttons), that call the methods in the Launcher bean (_launchActivity & closeCurrentActivity). It's fairly simple to rewrite the launcher helper methods in the launcher bean to call an imported ADF Library bounded task flow to open it as an activity, just referencing the correct task-flow.xml file.
However as you know a bounded task flow has a "Default Activity" entry point and one or more "Task Flow Return" exit points. What I haven't been able to work out is how when the bounded task flow exits via a task flow return, can we call the closeCurrentActivity method in the Launcher bean? The UI Shell code examples demonstrate closing a bounded task flow by menu options/or similar outside the bounded task flow in the UI Shell, but it would seem reasonable if the bounded task flow exited via a "Task Flow Return" we should be also able to close the activity tab too.
(....and as extension, before we even do that potentially call the checkState/isDirty() method to stop the user closing the activity too, but again driven by the bounded task flow attempting to exit).
I could imagine inserting code into the bounded task flow finalizer to close the activity tab, but this pushes the UI Shell tab activity management logic into our standalone ADF Library bounded task flows which isn't ideal, especially if we want to later reuse them in another app which doesn't use the UI Shell.
Any suggestions welcome.
Thanks & regards,
CM.

And we're back again.... what's a couple months between friends?
So it turns out after testing our app (d@mn, so close) that we've hit a bug with this approach.
Our current app allows one BTF to be open in the UI Shell at any one time. Our menu options automatically open one BTF at a time by the user (max one open), and close the previous BTF. However we have some "special" BTFs that require the user to explicitly close the BTF, which in turn makes use of the regionNavigationListener solution I described earlier in this post.
However we discovered a bug when we do a complete cycle of the 15 embedded regions within the UI Shell.
Say we:
1) Open a normal BTF in region 0
2) Open another normal BTF in region 1 (our solution automatically closes the previous BTF)
3) We then open another BTF (again the previous BTF is closed) in region 2, yet this a "special" BTF requiring the user explicitly to close it. Upon the user closing the BTF - this results in the regionNavigationListener being called and the removeTab() method called to close down the BTF in the UI Shell
4) The user then open/closes multiple normal BTFs, one by one, rotating through regions 3, 4, 5 .... eventually back to 1 again
5) Then the bug occurs - on opening any BTF back in region 2 (as part of the complete cycle of all regions), the tab for the region 2 opens, correct title, and via debugging the Tab.class has all the right settings including taskFlowId, but the tab is incorrectly empty
doh!
I've managed to track a symptom of the problem down that may explain what's happening.
Each time a tab is rendered with a BTF, the Tab classes getBinding() method returns a reference to the binding required for the current BTF. However for some reason on the complete cycle, for "r2" it returns the binding for the previously user-closed BTF from step 3 above, even though we called the TabContext.removeTab() method.
What I haven't been able to work out is how the bindings get turned on/off dynamically for each BTF being invoked. Presumably for some reason on step 3, the BTF's bindings aren't being correctly removed from r2 even though we called TabContext.removeTab().
If anybody has any brain waves about what's going on and how to fix this problem, your help appreciated.
Regards,
CM.

Bounded Task Flow as Dialog - 404 Not Found

I am attempting to call a bounded task flow as an inline dialog from a view activity in my unbounded task flow. When the bounded task flow is invoked, I am presented with a dialog which contains a "404 Not Found" error. I thought that I had this right based on what I read in the developers guide:
1. In my unbounded task flow, create a task-flow-call activity
a. Set the "Run As Dialog" behavior to "true"
b. Set the "Display type" to "inline-popup"
2. Add a named control flow which associates a view activity to the task-flow-call activity.
3. In the related view activity page, add a command control with the "action" set to the name of the control flow, and "useWindow" set to "true".
4. In my bounded task flow, add a view activity which points to the JSF document (jsfx) that I want to display in the dialog.
5. I add a task flow return activity to my bounded task flow, and a control flow that associates the view activity with the return activity.
6. In my page fragment, I add a cancel button which invokes the control flow from the view activity to the return activity.
Run
When I click on the command button which invokes the bounded task flow as an inline pop-up, and I see an inline pop-up which contains the 404 page not found error.
I must be missing something fundamental here. I've scanned all the doc and the forum, but I don't see it. Will someone please point it out to me?
Cheers

I appreciate the response, but I am actually building an ADF application that I am running in the JDeveloper embedded WebLogic Server. These instructions are for deploying a task form composite app to a standalone WLS.
I'm just trying to run a bounded task flow in a dialog as described here: http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/taskflows_dialogs.htm#BABBAFJB
However, I get the 404 Not Found error when I invoke the bounded task flow from a command control. The dialog appears, but the default page of my bounded task flow is not in it.
Seems like this has to be a simple problem to fix. Anyone?
Thanks

Problem reentering task flow in dynamic region

Hi All,
I have problem with reentering task flow in dynamic region.
JDeveloper/ADF 11.1.2.3.0
Use Case:
Application contains bussines modules(implemented as bounded task flows) displayed in dynamic region.
In some modules, default activity is Method Call activity which performs some validations(input parameters, state of records in db, etc.)
and if some conditions are not satisfied, shows message to the user and exits module (navigates to Task Flow Return activity).
Problem:
If user tries to start the same module again, nothing happens(message is not shown).
If user choose some other module and after that start first module, message is shown(so I suppose this means that task flow was correctly exited first time but dynamic region state was not refreshed).
Current implementation info:
Dynamic region has attached regionNavigationListener which resets taskFlowId variable in dynamic region bean if regionNavigationEvent.getNewViewId() == null but this listener is not called if Method Call activity directly navigates to Task Flow Return activity.
(if user navigates to Task Flow Return activity from button on some page, this works as expected)
Also, I tried to reset taskFlowId variable from task flow finalizer and to programatically refresh region binding, but this still doesn't work.
So, am I missing some point about refreshing dynamic region or this is bug in ADF?
Thanks,
Dario

I don't have any popup.
There is only page which contains dynamic region.
This dynamic region can be empty or can contain one of business modules(bounded task flows) which are invoked from menu.
In some cases business module must exit(by invoking task flow return activity) immediately after invocation(because some business validations fail).
In this case, module will show message to the user.
Problem is that if user call the same module again, nothing happens(message is not shown) because regionNavigationListener(which only purpose is to reset taskFlowId variable when business module exits) is not triggered when Method Call activity(which is default activity in BTF) navigates to Task Flow Return activity.
Also, I tried to use Router activity instead Method Call, but problem still exists(regionNavigationListener is not triggered).
Obviously, regionNavigationListener is called only if navigating from page(or fragment) and this is probably a bug in ADF so I opened SR.

Can not commit when using region in bounded task flow

Hi All
I am using Jdeveloper 11g R2 (11.1.2.3) & Weblogic 10.3.5.0
I have 2 bounded task flow in my application (A and B)
Each contain a fragment with few tabs (using af:panelTabbed)
I have another common functionality in this 2 bounded task flows
So I create another bounded task flow and add it as a region in tabs in task flows A and B
But when I am going to the common tab and insert record and commit using task flow commit it is not commit records in database
Is something wrong ? Any ideas how I can fix it?
Regards
Mohsen

Hi Frank
I am using below code for commit (from TaskFlowUtils class)
public void commitTaskFlow() {
getDataControlFrame().commit();
public DataControlFrame getDataControlFrame() {
BindingContext bindingContext = oracle.adf.controller.binding.BindingUtils.getBindingContext();
String dataControlFrameName = bindingContext.getCurrentDataControlFrame();
DataControlFrame dataControlFrame = bindingContext.findDataControlFrame(dataControlFrameName);
return dataControlFrame;
Your comment was too helpful , I change data control scope to shared and it is working now
One more related question:
Is adding bounded task flow into another fragment as region an advised approach?
Thanks a lot

Dynamic method calls in bounded task flows?

Hi!
I have the following scenario:
We are developing a framework in which we would include modules as ADF libraries (as JAR files) with bounded task flows. This framework contains a bean class with bindings for some UI components in framework which I enable or disable (depends on user action). That is the main reason bean class should be present in framework application.
I have a bounded task flow in every module which needs to call a method in bean with UI component's bindings that would enable or disable that component.
How can I achieve that? To pass bean as a parameter into bounded task flow and then call its methods? That is dynamic method calls for bean.
I'm using JDeveloper 11.1.2.1.0
Thanks for your help
Regards, Marko

Hi,
I explained this; +"I have a bounded task flow in every module which needs to call a method in bean with UI component's bindings that would enable or disable that component. How can I achieve that? To pass bean as a parameter into bounded task flow and then call its methods?"+ a couple of times already (not sure if it was all for you) and don't think I change my position here. I also explained how to use a ValueExpression to lookp a managed bean containing component bindings (should be in requestscope).

Doco/functionality mismatch: Adding a Bounded Task Flow to a Page

Hi JDev team
With JDev 11g TP4 and the latest published ADF Guide in hand, under section 14.3 "Adding a Bounded Task Flow to a Page", subsection "To add a bounded task flow containing pages to a JSF page:" it notes that when you drag n drop a bounded task flow from the App Navigator into a JSF page you get the choice of creating a button or link. I don't get this option, instead I can create a region or a dynamic region in the drag n drop submenu.
Cheers,
CM.

Chris,
note that it says "containing pages", not "containing page fragments". If your taskflow contains page fragments "jsff" then the choice is a region, if it is pages (jspx) then the choice is button or link to launch the taskflow.
Let me know if this still doesn't work for you

Calling bounded task flows imported as ADF libraries

Hello,
I have a main application referencing many bounded task flows included in ADF libraries.
Is there a way to make the application not throwing exceptions if one of these libraries including the called task flow is not found?
The first question is how to catch the exception "Caused by: oracle.adf.controller.ControllerException: ADFC-02001"
The second problem is that once an exception is thrown , the only way to make the application work again with that task flow is to redeploy the whole application with the missing library in the proper place.
It seems it is not possible to just add the library at run-time.
Redoplying an application also seems to invalidate all the current open sessions.
Could you give me suggestions or best practice on making the main application more indipendent from the libraries?
Thanks.

Hello Frank,
It seems there's no way to catch the exception thrown when dinamically calling a bounded task flow in a (missing) library. In facts, I added the single page of the main application as default exception handler activity. I also tried to catch ALL exceptions in the Launcher class below, but I had no luck at all. Task flows are called dinamically from this common piece of code (appropriate for the UI Shell template):
try {
if (newTab) {
TabContext.getCurrentInstance().addTab(title, taskflowId);
} else {
TabContext.getCurrentInstance().addOrSelectTab(title,
taskflowId);
} catch (TabContext.TabOverflowException toe) {
toe.handleDefault();
} catch (ControllerException ce) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (RuntimeException re) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
} catch (Exception e) {
System.out.println("The flow arrives here " + title + ": " + taskflowId);
I also tried to call the task flow in a remote application, but TabContext.getCurrentInstance().addTab(title, taskflowId) expects the taskflowid to be part of the main application, not of the remote app, since addTab() always add a "/" before the taskflowid String passes as parameter.
So again my question: is there a way to profit by the dynamic features coming along with the UI Shell template, where task flows can be really referenced and called each time at run-time, no matter if libraries containing these task flows are present or not when deploying the caller application?
I also repeat that from the tests I have done it looks like I can deploy the caller application without the referenced ADF libraries in their place (containing taskflows that should be called at run-time on user actions), but the problem in this case is that after that moment there's no way to fix the problem by just adding the missing library, that is you cannot place the library where it is expected to be and expect the caller to work after next call; this will just not work until next deploy of the calling application when libraries are in place . We also don't want completely separate web applications. We need task flows integration with the chance to modify and deploy these taskflows as ADF libraries at run time, separately from the caller of the taskflow, without needing to restart/deploy the caller application everytime a libraries changes or a missing library is added.

Bounded Task Flow Navigation Issue

Hi,
I'm using Studio Edition Version 11.1.2.3.0.
I have a main page with a panel splitter. The right side has a dynamic region and the left side contains links to launch a bounded task flow in the dynamic region.
One of my task flows is a search form and has a call to another bounded task flow when I click on a command link in the table.
My issue is if I want to return to search form, clicking on the dynamic task flow link doesn't render the search page.
I have a bean for my dynamic task flow and the taskFlowId variable shows the url of my search page, but the navigation does not happen.
Is there something that needs to be reset for this to work?

Hi Frank,
Sorry about being vague.
I've compiled a little project using the hr sample db that duplicates my issue.
Let me know if you have issues downloading it.
I can provide the project via email if needed.
Change your db connection to whatever you've defined for the hr db. I have mine running on a slave machine.
If you click on "Search", search for an employee and then load the employee details by clicking on the employee id link in the table, the region navigates to the employee details page.
However, if you click on "Search" again, the region does not navigate to the search page, it stays on the employee details page.
I'm hoping it's just a setting in the properties for the task flow or the page fragment, but I can pen some code if needed.

Bounded Task Flow is not rendering

Hi all,
I am very new to ADF. I have a problem related to bounded task flows. I created bounded task flow with two simple steps like ViewX.jsff and EditX.jsff. Then I created a jsf page and put a splitter into main frame. On the left side of splitter, the master data of X is placed as read-only table. And in the right side of the splitter, I draged and dropped bounded task flow. It is render properly in jdeveloper editor, however when i run the page, bounded task flow is not displayed. I did some solution research about this problem in the forum. I implemented ADF Authentication and Authorization with HTTP Basic Authentication. I dont want a login form. I gave grants to anonymous-role and authenticated-role but it is still not working.
Indeed, I dont want to implement a security procedure at the moment. However, if i disable security, application throws an error message about permissions. Also, is there a way for running bounded task flow while security is not enabled?
Jdev Version: 11.1.2.2 JSF 2.0
Sorry for bad English.
Regards.
Anil.

Hi,
I have already given grants to Bounded Task Flow. However it is still not displaying when i run the page.
If i disable security, i am getting the following error log when i run a page with bounded task flow.

Bounded task flow task-flow-return to unbounded task flow throws 404

I'm using an unbounded task flow (adfc-config.xml) to call a bounded task flow (task-flow-definition). All navigation in the bounded task flow works well, data is committing. (I am omitting many of the pages from the bounded task flow to keep this post shorter. If I can get this first page to return to the unbounded task flow, I can copy it forward.)
My problem is when running from the unbounded task flow, I cannot seem to configure the bounded task flow to return to the login page inside the unbounded task flow, which called it, without a 404 error.

Jdev version is 11.1.1.2. WLS is 10.3
Currently trying to get it to work on the Integrated WLS before deploying an ear to the console.
I don't know how to configure security, but here is the piece from my web.xml:
<filter>
<filter-name>JpsFilter</filter-name>
<filter-class>oracle.security.jps.ee.http.JpsFilter</filter-class>
<init-param>
<param-name>enable.anonymous</param-name>
<param-value>true</param-value>
</init-param>
</filter>
Also,, I'm finding these hash entries in both Model.jpr and ViewController.jpr:
<hash>
<value n="id" v="BC4J Security"/>
<value n="isJDK" v="false"/>
</hash>
Any help would be greatly appreciated. I'm way behind on this deliverable...

Is the task-flow-return the ONLY way to pass values from the bounded to the unbounded task flow?
Or is it possible to use a control-flow-case inside the bounded task flow like this, that refers to the unbounded task flow to navigate from the bounded back to the unbounded task flow?
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<task-flow-definition id="task-flow-definition">
<task-flow-call id="adfc">
<task-flow-reference>
<document>/WEB-INF/adfc-config.xml</document>
<id>adfc</id>
</task-flow-reference>
</task-flow-call>
<control-flow-rule id="__41">
<from-activity-id id="__42">ContactInfo</from-activity-id>
<control-flow-case id="__43">
<from-outcome id="__44">logout</from-outcome>
<to-activity-id id="__45">adfc</to-activity-id>
</control-flow-case>
</control-flow-rule>
I've tried every conceivable way to navigate from the bounded task flow, to the unbounded task flow, and the only consistent thing I receive is a 404. Is this a security issue?

Open new Tab within a bounded task flow

Hi,
is it possible to open a new tab when iam within a bounded task flow
There is a code corner article about starting a task flow in a new tab,
but that is not applicable for my case, I want the new tab for only
one view activity within the bounded task flow.
I tried:
public void launchNewWindow()
FacesContext fctx = FacesContext.getCurrentInstance();
String viewURL = ControllerContext.getInstance().getLocalViewActivityURL("PDLG_ListeDrucken");
// String taskflowURL = ControllerContext.getInstance()getTaskFlowURL(false, new TaskFlowId(taskflowDocument, taskflowId), params);
ExtendedRenderKitService erks = Service.getRenderKitService(fctx, ExtendedRenderKitService.class);
StringBuilder script = new StringBuilder();
script.append("window.open(\"" + viewURL + "\");");
erks.addScript(FacesContext.getCurrentInstance(), script.toString());
ending up in an "HTTP Error 403--Forbidden"
Thanks in andvance

Yves,
Always mention your JDev version.
Can you explain your usecase a bit better? If you are trying to open one view activity alone from the entire taskflow in a separate tab, its not possible. Probably, you might want to add the view activity in question to a separate taskflow and use the approach in the code corner article.
