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

How to pass arraylist through URL ?

Hi,
Can we pass arraylist through URL using params.put ?
If so then how to access each value?..because pageContext.getParameter with return string...
Any other method can we use ?
Thanks

You should store in on the session or transaction depending on the scope.

Passing parameter through url to report

Hi
I'm sorry if this question already exist anywhere in forum i didnt found it.
so my question is:
CAN I PASS PARAMETER VIA URL TO REPORT USING WEBFORM
i don have RAS(Because in beta version of 2008 is this not included)
I tried
http://localhost/CRWEB/Default.aspx?param0="value" ->here i'm prompt for value instead of showing report with set value
and
http://localhost/CRWEB/DocumentDoc.rpt?param0=krneki&init=html_page -> here i prompt to save rpt file
so But both doesnt work!
OR it is necessery to have RAS to pass parameters through url
thanks for quick answer

URL reporting and RAS are not available with CR2008. To view reports over the web you will need to use the Crsytal Reports for .NET runtime engine inside a .NET app. This engine is licensed with CR 2008.

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 ?

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

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

ADF UI Shell Pattern- How to pass parameter to the called bounded taskflow?

The sample Launcher class of the ADF UI Shell template has the following code:
    private void _launchActivity(String title, String taskflowId, boolean newTab)
      try
        if (newTab)
          TabContext.getCurrentInstance().addTab(
            title,
            taskflowId);
        else
          TabContext.getCurrentInstance().addOrSelectTab(
            title,
            taskflowId);
      catch (TabContext.TabOverflowException toe)
        // causes a dialog to be displayed to the user saying that there are
        // too many tabs open - the new tab will not be opened...
        toe.handleDefault();
    }How do I pass a parameter to the bounded taskflow that will be launched?
For example:
1) I have a list of employees displayed on a tab.
2) When I select a record and click an edit button inside the tab, A separate tab should open with the corresponding employee to be edited.
How then could I pass the employee id to the edit-employee-task-flow?
I can't think on how/what would a "calling taskflow" come into this picture?
help!

Hi Arunkumar,
Thanks for the info. I was actually using EJB DataControls, and something similar to what you have suggested can also be done programmatically, but I wanted to follow the one promoted in the Fusion Developers' Guide to take advantage of the "ADF task flow framework" (like pass-by-value, pageflowScope, etc.) especially that we were having problems when we will just follow the procedures that was presented in the tutorials(I mean that- not all the procedures in the tutorials will work on an application based on the UI Shell pattern which do have multiple active taskflows.).
For instance, you have an active List of employees in one tab, and two other tabs that try to edit employee records. If these employee list and employee edit forms are based on a single iterator binding, then what would happen to the information in the two edit forms on each separate tabs if you selected another row on the employee list tab? -- In our case, the edit tabs' values synchronized to the new selected row in the list tab.
There are sure many work-arounds for these, but I am looking for a cleaner, clearer, or best way to handle this scenario.
regards,
pino

Passing Parameters to Bounded Task Flow from JSPX

Hi All,
1. Created a JSPX page using UIShell template. This page contains 4 UI Components (InputComboBoxListOfValues) in SingleObjectContextArea. Created a Managed Bean for this page and capture the selected value in ValueChangeListner and added the value to pageFlowScope.
2. Created Unbounded Task Flow, dragged the JSPX page.
3. Have a existing Bounded Task Flow with page fragments, it has MethodCall activity which is expecting inputParameter values from JSPX.
4. To call the Bounded Task Flow from Unbounded Task Flow (has JSPX page) created 2nd JSPX page using UIShell template.
5. Dragged the existing Bounded Task Flow into 2nd JSPX page, in context menu selected Region. This Region is created in SingleObjectContextArea of UIShell.
6. When dragged its asking about inputParameter mapping of Bound Task Flow.
7. Configured the inputParameter value which are coming from pageFlowScope.
8. Dragged the controlFlow from 1st JSPX to 2nd JSPX page to complete the Navigation.
9. When running the Unbounded Task Flow, it showing 1st JSPX with LOV.
10. Selected the values and clicked on Submit Action.
11. Its now showing 2nd JSPX which contains Bounded Task Flow.
12. But its displaying empty records table. (Note: I am passing parameters to MethodCall inputParameters as pageFlowScope, My DB has displaying records based on inputParameters when tested it from OrcleSQLDeveloper)
Could any body help me on this issue.
My Code Snippets of Data Binding of 2nd JSPX page which has Bound Task Flow as a regionModel.:
<taskFlow id="TaskFlow1"
              taskFlowId="/WEB-INF/oracle/apps/TaskFlow1.xml#TaskFlow1"
              activation="deferred"
              xmlns="http://xmlns.oracle.com/adf/controller/binding">
      <parameters>
        <parameter id="PartnerKeyType" value="#{pageFlowScope.PartnerKeyType}"/>
        <parameter id="PartnerKey1" value="#{pageFlowScope.PartnerKey1}"/>
        <parameter id="InteractionPartnerRole"
                   value="#{pageFlowScope.InteractionPartnerRole}"/>
        <parameter id="BusinessProcessName"
                   value="#{pageFlowScope.BusinessProcessName}"/>
      </parameters>

Hi
first of all Can you get the pageFlow scope variable in taskflow?which you are passing from jspx page?
if you are able to get the Lov value in Taskflow try refresh taskflow on changing the LOV.
you need to add input parameter type as boolean,change the parameter from false to true when the LOV value changed.
now use refreshifNeeded property in pagedef bindings file

Bounded-Task-Flow Page Fragment Control Flow Help

jDeveloper: 11.1.1.0.2
I am having an issue trying to figure out the correct way to use control flow cases between a bounded-task-flow with page fragments and an unbounded-task-flow page. We have taken the approach in our application to have a few shell / container pages to host bounded-task-flows made up of page fragments to facilitate re-usability and to speed up development. There are 4 or 5 shell pages on the applications unbounded-task-flow. As of now, we have about 20 page fragments that are implemented as bounded-task-flows. These fragments don't do much now, meaning there is only a single fragment in each bounded-task-flow. The issue I am having is trying to invoke a control flow navigation action from one of the fragments to load a different shell page.
For Example, shellPage1.jspx contains fragment-flow-1 as a region. In my adfc-config.xml I have shellPage1.jspx and shellPage2.jspx, with control flow cases "toShell1" and "toShell2" respectively connecting the two pages. I have a link's action bound to the "toShell2" within the fragment that makes up fragment-flow-1. When the application is run, shellPage1.jspx and its fragment are displayed. But clicking on the link in the fragment ("toShell2") does absolutely nothing. It does not navigate me to the shellPage2.jspx as expected. What am I doing wrong here or do not understand?
If the fragment is included as a JSP include, and not a bounded task flow include, everything works as expected. This is not desirable as we then need to copy the fragment's pageDef into the shellPage's pageDef to get the DataControls to function.
If the faces-config.xml is used instead, and a JSF navigation case is used, it will also work as expected. This is not desirable because we really don't want to be mixing adcf-config and faces-config.
So I am really stumped here.... Thanks in advance!

Hi there:
In your case, the adfc-config.xml has the control flow case between shell pages. And the task-flow-N.xml or your-task-flow.xml for each page fragment by default doesn't inherit control flow case from their containing shell page. In your case, in the page fragment task-flow.xml, you should add a "Parent Action" to flow to shell page2 for example. The outcome of "Parent Action" would be "toShell2" if calling from ShellPage1 page fragment.
Is this 'Correct' or 'Helpful' for you? Please mark it as so if it does.
Good luck,
Alex

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

How to use a managed bean in a bounded task flow without definig it in adfc-config

Dear all
I create a bounded task flow without page fragments (the pages are jspx), i created a jspx page with a button that its action has bounded to a managed bean function.
i defined the managed bean on the corresponding bounded task flow, but it does not work.
But there is no problem when i define the managed bean in adfc-config.xml.
can anybody help me with this problem.
is it possible to use jspx page with backing bean in bounded task flows, without defining the beans on adfc-config?
Thank you very much

Dear Timo
I use jDev 11.1.1.6 and the scope is Request.Although when i use task flow page fragment and create jsff pages, there is no problem.

Any example for (bounded task flow) popup return value

I need to know what is the type of popup RETURN VALUE
any example will be great

I want to get parameter form popup bounded task flow with NO page fragment (task flow 1) to jsff page from another task flow with page fragment(task flow 2)
I applied the scenario exist in URL's in first replay and it didn't work
when I select task flow 1 from inside task flow 2 diagram I found in its inspector page filed called "Dialog Return Value"
how can I use this field

Best Practice - Bounded Task Flows, Regions and Nested Application Modules

Using JDev 11.1.1.3; understand that it's generally considered good practice to just have 1 root application module servicing model content / services for each page. In our application, we've used a number of bounded task flows and page fragments deployed as af:region's into pages as either a) views targeted in page-flow navigation, b) tab panel content inside a regular jspx, or c) af:popup / af:dialog content. As it stands, we've not engaged nesting of the application modules for this embedded region content, so these regions are no doubt instantiating new AM's if/when invoked. Should the AM's servicing these embedded regions be deployed nested within the root AM's, and then if so, does this change the way that the jsff / fragment content is actually developed (currently as per any other jspx using the DataControl pallete). Or are the best-practice directives talking about a page as being the design-time / declarative composition of content rather than the run-time aggregation of page + fragments ... in which case the fact that our embedded fragments are not using nested AM's is unlikely to concern.
Thanks,

How to pass a parameter to a bounded task flow?

Hi,
We are facing issue while passing parameter from a bounded task flow to another bounded task flow and then showing the passed parameter in a jspx page.
We have a caller task flow with following component:
1. A jspx page
- In this jspx we have a text box have its value as #{pageFlowScope.inputvalue}.
- Also we have a command button which has its "Action" as the control flow that leads to the "called" task flow.
2. A bounded task flow named "called".
So, we call the "called" task flow on the button click in the jspx page.
Also, in called taskflow we have a jspx page where we are using a output label to show the parameter passed from caller task flow to the called task flow.
We performed the following steps to set the parameter passing from caller task flow to the called task flow.
1. Select the input text component on the JSF page.
2. In the Property Inspector, enter a value for the input text component. You can specify the value as an EL expression, for example #{pageFlowScope.inputValue}.
3. In the Application Navigator, double-click the name of the called task flow to open its diagram.
4. Click the Overview tab for the called task flow.
5. Click Parameters and expand the Input Parameter Definition node.
6. Click the Add icon next to Input Parameter Definition.
7. In the Name field, enter a name for the parameter, for example, inputParm1.
8. In the Value field, enter an EL expression where the parameter value is stored and referenced, for example, #{pageFlowScope.inputValue}.
9. In the Class field, enter a Java class for the input parameter definition. If you leave the Class field empty, its value is by default implicitly set to java.lang.String.
10. In the editor, open the diagram for the calling task flow.
11. In the Application Navigator, drag the called ADF bounded task flow and drop it on top of the task flow call activity that is located on the calling task flow. Dropping a bounded task flow on top of a task flow call activity in a diagram automatically creates a task flow reference to the bounded task flow.
12. In the Property Inspector for the task flow call activity, click Parameters and expand the Input Parameters section.
13. Enter a name that identifies the input parameter.
14. Enter a parameter value, for example, #{pageFlowScope.parm1}.
Now when we try to fetch the value of parameter using #{pageFlowScope.parm1} in the jspx in called taskflow, its not giving the desired value.
We even tried to set the to and from parameter of the jspx in called askflow. But no success.
Can anyone let us know if we are doing smething wrong or exact steps to configure passing of parameters to a bounded task flow and retrieving it in a jspx page will also help.
Thanks in advance.

Hi Tushar,
In step# 14, the value should be "#{pageFlowScope.inputValue}" (should be the same as the value in step#2) .

Master-detail table where detail is in a bounded task flow

Dear all,
Iam pretty much new to ADF 11g. I have the following question.
I have a search form(using af:query) created from the View Criteria of a view. The search results are displayed in a master-detail table, since my view has the following form in the data control:
MasterView ->DetailView
I would like that the detail table be part of a page fragment of a region of a bounded task flow. And of course, the detail table should be refreshed every time another row is selected in the master table.
Is this feasible? Because I find difficulties in the following areas:
1. How to pass a parameter to the bounded task flow that will display the detail table?
(I suppose that I will need to build a new view to display the DetailView. In the WHERE clause I will have to pass the id of the row clicked in the master table.
2.How passing the variable to the bounded task flow of the detail table be implemented when clicking the row of the master table? In similar examples I have seen, e.g. in the ADF Code Corner, there is always a submit button that sets a pageFlowScope variable.
Is my approach feasible or it needs a lot of ADF twisting?
Edited by: dimitris74 on Sep 12, 2011 6:20 AM

Hi,
If you have two different regions in your page for master and details and you want to refresh the child table based on your master row selection then you can use the contextual actions. Raise an event whenever you select a row and send your master-table id as the payload. Have a handler method at the detail page and execute some logic to get the rows for the selected master record.
I hope it helps you.
Thanks,
Lakshman
