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

Call adf bounded task flow library programatically

I have a master application where I have one page with a region where all the task flows are going to be aggregated as tabs. Each task flow represents a module and is in a separate application. I add the adf library to the master application for bounded task flow "Module1".
This is my code that works if the bounded task flow is in the master application:
TaskFlowBindingAttributes tfAttr = new TaskFlowBindingAttributes();
tfAttr.setId("Module1");
tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/module1.xml","module1"));
taskFlowList.add(0, tfAttr);
List<UIComponent> tabs = this.getPanelTab().getChildren();
for (int i = 0; i < tabs.size(); i++) {
RichShowDetailItem tab = (RichShowDetailItem)tabs.get(i);
tab.setDisclosed(false);
RichShowDetailItem tab = (RichShowDetailItem)tabs.get(index);
tab.setDisclosed(true);
But if bounded tak flow is in separate application the code doesn't work, it shows a blank page and i have defined a page with some panel boxes. So how shoud i call the bounded task flow programatically??.
I am working with Jdeveloper 11.1.2.3.0, thank you

Yes I see it in the component palette. I found the problem, I see in the task-flow-registry.xml that the path for the bounded task flow is: "module1.xml" and not "WEB-INF/module1.xml". What sould be the correct path?.

Call a bounded task flow from within another bounded task flow

Hello
I am using Jdev 11g Release 1 and need help with the following issue...
Here's an outline of my application..:
1. There is a main .jspx page with icons to choose different paths.
2. Each icon denotes a bounded task flow with TRAIN.
3. Upon clicking on any icon, you get into a series of TRAIN STOPS.
4. On one of the TRAIN STOP there is a button to ADD NEW which shows a popup that is tied to another bounded task flow with TRAIN STOPS.
5. This taskflow 2 calls a method as its default activity.
The issue is when I click on ADD NEW, the popup displays empty. I even put break points on the method and it doesn't even go to the method. The input parameters on the method have been checked so I know that is not an issue. Any clues as to why it won't open the popup..?
Any help will be greatly appreciated.

and also check if the DataBindings.cpx has the correct reference of the method definiiton file..Did this..all references point correctly
or otherwise can u drag and drop the method again on to the taskflow and try.. if this time it had created all entries correctly.?Tried it ...doesn't work =(

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).

How to pass parameter through URL to bounded task flow with page fragment

I want to pass parameter to Bounded Task Flow With Page Fragment trough URL
as I start this taks flow with router and according to this Param I will rout the user.
I added input param to taks flow named direction and make the task flow called URL invoke url-invoke-allowed
<input-parameter-definition id="__41">
      <name id="__42">direction</name>
      <value>#{pageFlowScope.direction}</value>
      <class>java.lang.String</class>
    </input-parameter-definition>but I don't know how to add this to the JSPX that I will add the bounded task flow Inside.
and How to pass this from URL

Hi,
url-invoke-allowed is only required if the task flow itself is directly accessible from a browser (which is not the case at all if the task flow uses page fragments). To pass input parameters to a task flow that is embedded in a region and that has input parameters, you define the input parameters on the taskFlow Id that is created in the PageDef file of the containing page. To learn ADF task flows, have a look at the videos below. They also contain a sample for passing parameters to a region

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 ?

Calling a bounded task flow from an unbounded task flow

How can I navigate from an unbounded task flow to a bounded task flow....
My situation is as follows:
In the adfc-config.xml, I have a view activity ADMhome, Wildcard as well as a task-flow-call, admTaskFlow. A control flow goes from the wildcard to ADMhome while another control flow goes from the wildcard to task-flow-call.
I have a bounded task-flow "adm-task-flow" with two view actitivies: AdmListView and AdmPageView with AdmListView as the default activity. A Control flow goes from the AdmListView to AdmPageView, all pointing the page fragments
I created another page ADMregion which is a (jsf) where I dragged the adm-task-flow onto.
When I ran the application, the home page displayed properly but when I clicked on a command button to invoke the "adm-task-flow", the application will not responded.
When I looked at the log message, It gave this message:
<TaskFlowCallXmlImpl> <parse> ADFc: /WEB-INF/adfc-config.xml:
<TaskFlowCallXmlImpl> <parse> ADFc: Failed to parse element 'task-flow-reference'.
<ActivityXmlImpl> <parse> ADFc: /WEB-INF/adfc-config.xml:
<ActivityXmlImpl> <parse> ADFc: Activity metadata could not be parsed. [Activity Type, ID] = ['task-flow-call', ' admTaskFlow '].

Thanks for this clarifications...
I created a view activity in the adfc-config-xml and called the page (ADMregion) where the task flow was embedded. It worked well..
Another clarification I want is this, when do I use a task flow call to call a task flow? My thinking and my understanding was that when you create a task flow, you use a task flow call to invoke the task flow.
Pls another aspect I want you to guide me is on calling a java class from jsf and jsff pages. Being new in these technologies, I have having some difficulties navigating and putting all of them together. My problem is this:
I created a java class under the view package of Application Sources in the View Controller of my Application. The java class returns a value. I designed a jsff form with input fields and and command buttons. I want when I clicked on a command button to take a parameter from the input field and pass it to the java class, the after processing, the java class returns a value which I will place inside one of the input fields in my jsff form.

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.

Facescontext message in a bounded task flow with a jsff

Hi,
I have a jsf page that uses a page fragment. The page fragment uses a backing bean to do some task. In the backing bean I am creating a FacesMessage and adding it to FacesContext.getCurrentInstance().
Everythign works fine and i can see the message during the runtime.
When i create a bounded task flow using that page fragment, and include that task flow onto a page, i cannot see the message anymore.
Does someone have any idea what may be going on?
Thanks,

Hi,
does the page fragment have an af:message tag ? Since you are not refreshing the parent page, which usually holds the af:messages component, its not showing . At least this is where I see the problem coming from

Bounded task flow not executing in a default view activity.

Hi,
I am practising Region to Region Interaction between two bounded taskflows in an unbounded task flow.
I will just illustrate the theme:
*Unbounded task flow[ DEfault view activity(view1)]*
view1 contains Bounded task flow task 1 and task2.
task 1 contains fragment frag1 .
task 2 contains fragment frag2. I want to establish communication between task 1 and task2 through contextual events.
I have created managed bean seperately for each bounded taskflow bean1 in task1 and bean2 in task2 which are in session scope that is frag1 vaues are maaped to bean1 and frag 2 values are mapped to bean2.
I completed full flow of creating contextula events and event map too. I was stuck with errror.
So I created an application only with default view activity containg boundsed taskflow and fragments and respective beans without contextual event and event map , so that i can make sure atleast my basicview is executing properl;y. But I failed to have result.
Error is shown below:

The error logs point to an error in your EL that references the frag1 bean. Firstly, rather than use session scope you must consider using pageFlowScope for your managed bean.

ADF : Can we skip the default activity of ADF train in bounded task flow.?

Hi All,
I'm a newbie for ADF and JDev. Started learning from the documentation provided for ADF, I'm trying to create a bounded task flow which has a train component and every train stop should be enabled/skipped programmatically. I'm able to skip the train stops after reading the content provided at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/82-programmatically-navigate-trains-396873.pdf.
But I'm not able to skip the default train stop which is the first activity call in my case upon initialization.
Below are the steps I've followed :
1. Created a viewController project and created a bounded task flow in it with Train component enabled.
2. Added 4 views with train component marking the first view as default activity call.
3. As per the document I mentioned above, I added managed bean files to skip the train stop programmatically.
Now when i run the task flow, I'm able to skip the train stops number 2/3/4 but I'm not able to skip the stop number 1(first stop which is the default activity) on initialization.
As per ADF documentation, for a bounded task flow there must be a default activity assigned which will always be called first when we enter the bounded task flow. So that means, default activity will always be called upon initialization of that bounded task flow and never be skipped programmatically.? or else if there is a way to skip the default activity, then please let me know the documentation/steps to do this.
Thanks in advace.

Thanks Timo. Your idea resolved my issue. :)
I've created a new page in my bounded task flow which I've made as a default activity for that bounded task flow. Then I applied navigation through router and based on some condition I'm now able to move my control to my desired train stop. By this design I can do other customization on train button(Back/Next).

How to create a page-definition for bounded task-flow?

I should be able to create a page definition which declare all bindings required for a bounded task flow.
How do I do it in JDeveloper 11.1.1.2?
How do I navigate to the page definition when I am in the bounded task flow "Diagram tab"?

I found out the following:
1. To create a page-definition file for a bounded task flow
Right click on the "Default" activity (not a view activity) of the bounded task flow, select "Create Page Definition" from the context menu.
2. To go the page-definition file for a bounded task flow
Right click on the "Default" activity (not a view activity) of the bounded task flow, select "Go to Page Definition" from the context menu.
My new question is:
In JDeveloper 11.1.1.2, how do I create page-definition for a bounded-task-flow if all activities are view activities (page fragments) ?
How does JDeveloper I want to create page-definition for the task-flow instead of create page-definition of the page fragment or the page?

How to call page in adfc-config from bounded-task-flow return?

Hello everybody, I am using JDeveloper 11.1.2.3.0
I have in my adfc-config some pages and one bounded-task-flow (with pages, not page fragments). I call the bounded task flow from one of my pages but I want that when I return from the bounded-task-flow to redirect the page to another page rather than the page that called it. I dont know if this can be done, but do you have any idea on how to achieve something like this?
Thank you

Call a jsff page in an bounded task flow.

Hi,
Am using jdeveloper 11.1.1.6.0
I have a bounded task flow named welcomeTF.xml which calls another bounded task flow named LeadsTF. The LeadsTF bounded task flow contains 3 jsff pages(named lv.jsff, lv1.jsff, lv2.jsff).
WelcomeTF(Bounded TaskFlow)------------------------------------>LeadsTF(Bounded Task Flow).
When my user runs the jspx page the Welcome page(from WelcomeTF) renders which has 3 buttons (named Button1,Button2,Button3). These 3 buttons should call the LeadsTF Bounded task flow but with different jsff pages.
Button1 -------------------------------> LeadsTF(lv.jsff)
Button2 -------------------------------> LeadsTF(lv1.jsff)
Button3 -------------------------------> LeadsTF(lv2.jsff)
How can i achieve this? Please help me with the samples.
Regards,
Prasad K T.

You can define a TF parameter for the LeadsTF and use this parameter to route the navigation to either lv.jsff, lv1.jsff or lv2.jsff when entering this TF:
Add a TF parameter (e.g. call it "InitialTarget" and map it to #{pageFlowScope.initialTarget})
Add an ADF Router activity as a default activity in LeadsTF
Configure the router activity to navigate to the appropriate JSF fragment depending on the value of #{pageFlowScope.initalTarget}
Make the buttons in the parent TF set different values of the TF parameter when calling the LeadsTF

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.
