Default method on ADF Taskflow()

Hi Friends,
I am seeing a weird case in my ADF Bounded Taskflow - I see that the default method is called after the finalizer method. I am releasing all my resources in my finalizer method and so when default method is called it is throwing some exceptions.
Is there any property I can set to stop the call?
P.S: My Backing Bean is in PageFlow Scope.
Thanks a lot !

Thanks for the reply Timo.
I am working in JDeveloper 11.3
A bounded task flow never does running, so chasms are that you see it just restart - Does it mean, I need to run my page again? If so, I have done that.
Thanks.

Default method in taskflow

Dear all,
How to fire a default method at the begining of a task flow created from a human task?
If I want to store the task parameters to session variables at the begining of a task flow can I use a default method?
It will be great if you could furnish with example , specially the code to access task parameters in a taskflow default method.

Hi Sam,
Try this
//access request scope variable.
HttpServletRequest request=(HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String name=(String)request.getAttribute("Name");
//access page flow scope variable
Map pageFlowScopeMap = AdfFacesContext.getCurrentInstance().getPageFlowScope();
String name = (String) pageFlowScopeMap.get("Name");

Javascripts and ADF Taskflows

Hello All,
I am using JDeveloper 11.1.1.5 (on Fedora 64-bit).
This one has been driving me nuts for a while. I have uploaded a simple testcase here - http://dox.bijesh.info/SimpleJS.zip.
In this particular testcase, I have an ADF taskflow composed of 2 page fragments. This taskflow is embedded as a region in a JSF page. Both the page fragments include some javascript embedded via af:resource and invoked through a clientListener on a button within each. Now, the JS on any page other than the "default activity" page does not get fired on the button action. It is as if the javascript did not get loaded at all. In fact when I examine this in Chrome, the error console shows an error as soon as I navigate to the second page fragment - "Uncaught ReferenceError: jspage2 is not defined".
I have tried using trh:script and that had the same problem. This happens with referenced JS files (through the source attribute) too.
My original use-case is to build a reusable Maps component which involves quite a bit of Javascript. Being a reusable library, I wouldn't ideally have control of where my taskflow will be embedded. And therefore embedding the JS in the initial pages is not a viable solution.
All suggestions are welcome.
Best Regards,
Bijesh

ADF Taskflows with EJB and pageflow scope

Hi,
I am trying to create a simple registration page which is very simillar to FOD customer registration using EJBs instead of ADF BC.
I can achieve the registration in one page but I wanted to try this using a wizard based process using ADF taskflows.
I created a bounded taskflow with 3 pages. page1 is employee details, page2 is job details, page 3 is the summary page. I have JPA entities for Employee and Jobs and an EJB3 session Facade. I have used the Employees default constructor to create the UI bindings from the constructor section of the data controls. This creates an EmployeesIterator which I use it for bindings on all the three pages.
My question is can I use this Iterator binding in pageflow scope? If yes How do I do this?
The other way is to use a managed bean in pageflow scope and have UI bindings to the variables in managed bean. This option will work but I will not be utilising any of the features of ADF bindings.
Can anyone please suggest which is the better option.
Thanks
Venkatesh

Hi,
pageDef files can be shared, but their instances aren't. The caching is on the data control side, which means that instead of using a constructor you would break up the input form into method calls like
createPerson(String, fn, String ln, String address)
createInterest(String hobby1, String hobby2);
dagging and dropping the method calls should the reate an input form. Submitting the forms allows you to build a new person object on the session facade which at the end is committed. This way the ADF binding works across pages, operating on a single new object

Not able to get the value in ADF taskflow on load

Hi,
I have created an ADF task flow. I have created a ViewObject in this ADF taskflow and I am setting the value of this ViewObject using the java API.
The issue is that i need to show the data when this ADF task flow executes first time.
Currently I am getting the blank table in jspx page when ADF task flow is run. Now when I click on a button then I can see the required data in the table.
Please help me to solve this issue.

Thanks for the reply.
I have tried placing the code to get the set the data in table and display the same from table in bean constructor, but I am getting table value as null.
Looks like it is not able initialize the table until the jsff page gets loaded.
Does jsff page gets loaded after bean constructor method gets called ?

How to get BPM Payload attribute value in ADF TaskFlow

Hi,
           Activities which I did : I have created ADF Project. Then I created ADF TaskFlow through 'ADF TaskFlow Based on Human Task' option by locating BPM task. So now TaskFlow is been generated and also respective dataControl value also generated. In TaskFlow I created new .jspx file. I am going to design this jspx page by drag and drop from VO instances from dataControl. So for this jspx page, at runtime value will be populated from DB Table.
                  My Requirement : When the Flow initiated, there will be Parameter value passed to the TaskFlow through Payload which is available in DataControl. So now I based on the Payload parameter value I need to filter DBTable and show the respective value in jspx page which I created in TaskFlow. So getting Payload value and applying filter on VO based on Payload parameter value has to be done before rendering Page.
I tried to achieve this schenario as like below :
       - Assume like there is attribute called 'transactionId', for which value will be passed to the TaskFlow through DataControl. I created VO based on EO and appended where clause as : "VO.Trans_Id = : bindVar". Created bindVariable called 'bindVar'. In jspx page I just Drag and Dropped VO instance as form. And also I drag and Dropped 'transactionId' as outputText from Payload. And also I created ExecuteWithParams in Binding section of PageDef and mapped that one with invokeAction item in executable section. So now both payload Iterator and invokeAction will be created in PageDef. I kept Iterator as in the order of : PayloadIterator at first and InvokeAction second one, So that at runtime it will execute in that order. And also I given "refresh" property to payloadIterator and invokeAction to 'renderModel' and I mapped PayloadIterator id to refreshAfter property of InvokeAction iterator. Now at runtime, So at runtime updated/Newvalue will be retrived to Payload attribute by executing payloaditerator. So now for 'transactionId' value vill be retrieved. Next invokeAction will take value from newly retrieved 'transactionId' as input and execute query. So now VO will be filtered and need to be shown. But instead of that getting error saying like 'No outcome metadata specified for method call activity 'null'.'
Is this way is correct? If yes, then What mistake which I have done?
Is any other way to acieve this schenario?
Do the needful.
Thanks with Regards,
PraveenKumar.N

Guessing you might have looked at this at some point, but you might want to consider using the setCurrentRowWithKeyValue method to do this.
Here's a blog post that I wrote a while back that goes through step-by-step what I think you're trying to accomplish: Using a BPM Process Variable on an ADF form to Retrieve Database Information | AVIO Consulting

ScrollBar Behaviour of ADF Taskflows rendered as Inline Popup

Hi All,
I am using Jdeveloper 11.1.1.5.
I have created a bounded Taskflow and then i have used two other taskflow in my current taskflow as Inline Popup.Functionality wise everything works fine but if my given taskflow size i.e the window width and height parameters are small then the page content then automatically the Scroll bar comes into the Taskflow at runtime.
It is good to have a scroll bar automatically but it doesn't work in a correct manner. When my page render , the scroll bar is situated at the edges of the taskflow .Now if i go down , automatically scroll happens and comes to the default position.
This makes users bit in a hazy situation. I don't want the scrollbar in the ADF Taskflow which rendered as Inline Popup.I want the scrollBar inside thr page which can help users to do scroll in a proper way.
Is there any way to achieve this ?

Shah

Change default text in adf faces component in Webcenter Spaces

Hi ,
Here is the link that I found to change the default text in adf faces component. http://www.oracle.com/technetwork/developer-tools/adf/learnmore/49-skin-component-labels-169191.pdf
Scenario is simple :
Taskflow "ABC" is used in webcenter space through imported Library in spaces App. Taskflow "ABC" have the pageFragment "view1" and fragment has a adf table on that page. I was trying to change the "Detach" text using below code in above provided instruction.
{ "af_panelCollection.LABEL_DETACH_TABLE_DLG", "Any name for the Detachable Table" },
{ "af_panelCollection.LABEL_DETACH_TREE_TABLE_DLG", "Any name for the Detachable Tree Table" }
Query/Problem : I did change in the trinidad-skins.xml of DesignWCSpaces app ... redeployed the war.. But the text didn't changed. The above steps worked fine for individual ADF application ... SO what's wrong with implementation on Webcenter Spaces ?

Hi.
Basically you have to do the following:
Create an ADF JAR Library including your Skin (JS, Images, CSS Skin, Resources Bundles and trinidad-skins.xml)
Deploy the ADF JAR Library as Shared-lib in WebLogic.
Include in your weblogic.xml of the WebCenter Portal (Formerly Spaces) deployment via DesignWebCenterSpaces or the new extension the reference to the shared-lib.
Restart WebCenter Portal (Spaces). When starting WebCenter Portal (Spaces) it looks inside of the Classpath for all trinidad-skins.xml files.
Setup your custom skin for a Space and test.
If the Skin is not selectable in the Administration Console then register your new skin downloading/updating/uploading from the MDS the generic-site-resources.xml file of the default scope GUID.
If you still have issues then may I priorize a Blog entry explaining this .

Easy way to evaluate a complex return type in adf taskflow

Hi,
I use a method call in adf taskflow where I call a bpel ws . This bpel has a complex return type. I want to evaluate in the taskflow router if STATUS==true . Can this be done with pageflowscope (in the method call , I have a return value) or do I need a methodIterator / accessorIterator in the pagedef.

nice try,
Unfortunately your method is easily circumvented by either 1.) disabling javascript in the browser preferences or 2.) viewing the source code for the page and clearly seeing the required password or 3.) simply bookmarking and visiting protectpage.html
It may take you 5 mins. to password protect your iweb site by using the method you've described, but it would take a visitor less than a minute to bypass the password protection. You need server-side scripting like php to enable real password protection so that information is processed on the server before the page is loaded.

How to display default value on ADF UI?

How can I display a default value on ADF UI? means upon a web page loaded, the default value should appear in a certain control (e.g. input text) without any user action.
I tried to assign a value through the backbean constructor but seems not working.
Thanks

The natural way would be to set the default value in the underlying model (which you did not mention). If you are using adfbc you can set default values e.g. in EO or VO. These values are then transferred into the UI.
This would be my preferred method.
You can also set default values in a bean method, but not in the constructor. Use a public method (e.g. init) to set the default values and call it as start activity in a bounded task flow. This ensures that each time you start the task flow the values are set.

Error in Creating Custom Business Methods using ADF Business Comp. Tutorial

I've been working with Jdev 10g Preview for a while. Now that we have Jdev 10g, I have to unlearn some of the Preview methods and learn the "real" way of doing things. To that end, I went out to the "Creating Custom Business Methods using ADF Business Components" tutorial. Unfortunately, I've found what I think is a mistake in the example code.
Specifially, ADF treats the default iterator on View Objects differently than previous BC4J versions. In the older versions, the iterator was positioned before the first row when you first executed a query. In that case, the hasNext() method was used to see if you had any rows at all. In ADF, however, the default iterator is positioned at the first row. So, if your query only returns one row, then the hasNext() method returns false!
Here's the code posted in the tutorial:
public Number getDeptSalaryTotal(String dept_id)
// get a department view object
DepartmentsViewImpl dept = getDepartmentsView1();
dept.setWhereClause("DEPARTMENT_ID = " + dept_id);
dept.executeQuery();
dept.first();
EmployeesViewImpl emps = getEmployeesView3();
Number salaryTotal = new Number(0);
while (emps.hasNext() )
Row empsRow = emps.next();
salaryTotal =
salaryTotal.add((Number)(empsRow.getAttribute("Salary")));
return salaryTotal;
As you can see, this is coded using the pre-10g semantics. It checks hasNext() at the top of the while loop. If there is only one Employee in the Department, hasNext() will return false since the emps View Object will already be positioned at the first and only row. There won't be a next row. So, the salaryTotal will be zero instead of the correct value. Alternatively, if there is more than one row, then hasNext() will be true, but the routine will skip the first row and start totalling salaries from the second row on.
The routine should be recoded as follows:
public Number getDeptSalaryTotal(String dept_id)
// get a department view object
DepartmentsViewImpl dept = getDepartmentsView1();
dept.setWhereClause("DEPARTMENT_ID = " + dept_id);
dept.executeQuery();
dept.first();
EmployeesViewImpl emps = getEmployeesView3();
Number salaryTotal = new Number(0);
Row empsRow = emps.first(); // Get the first row
while (empsRow != null ) // while we have a row
salaryTotal =
salaryTotal.add((Number)(empsRow.getAttribute("Salary"))); // add in the salary
empsRow = emps.next(); // get the next row
return salaryTotal;
I haven't actually executed this code, so there may be a typo or two in there. However, the basic idea is sound -- I think!
Please update the tutorial so we don't mislead people right at the start! :-)

Gary:
I have two questions for you:
1) Could you post the preferred code here?
2) Why is it the preferred method? I would think that creating and destroying another object (the temporary iterator) would be a bad thing.

Invoke ADF taskflow with parameters using POST

Hi,
Can someone give an example or point me to an example describing invoking adf taskflow with parameters?
The requirement is to have the parameters passed using POST method and not passing the parameters in the url.
Jdev: 11.1.1.4.0
Thanks!

Hi,
a use case for the requirement would have been good to have as yet I can't tell if I am helping you with something useful (hope so) or stupid (for which there would be a better approach to use instead if only we knew the use case).
Anyway, here's a document describing what you asked for

ADF Taskflow Navigation

Hi All,
I am stuck with a problem of ADF TaskFlows and need a help quickly.
The description is as follows.
After login to the application first page i encounter is a jspx page say start.jspx on which i have dragged a bounded taskflow called as TF1. I have 10 jsff pages in this taskflow say(A, B, C, D, E, F, G, H, I, J.)
Now on one of these pages (say A) i have a link which will open the page B. I have dragged another taskflow say TF2 on B. In TF2 i have 5 jsff pages say (AA, BB, CC, DD, EE).
Now from page BB i want to navigate to page D of the first taskflow.
Please help on the same.
Thanks

Bind RegionNavigationListener of the region(for TF2) with a bean method and in bean you can navigate from
if(regionNavigationEvent.getNewViewId() == null){
NavigationHandler nh =
FacesContext.getCurrentInstance().getApplication().getNavigationHandler();
nh.handleNavigation(FacesContext.getCurrentInstance(), null,

Issue with SharePoint foundation 2010 to use Claims Based Auth with Certificate authentication method with ADFS 2.0

I would love some help with this issue. I have configured my SharePoint foundation 2010 site to use Claims Based Auth with Certificate authentication method with ADFS 2.0 I have a test account set up with lab.acme.com to use the ACS.

Need to Hide Objects Default method in Approval Task

Dear All,
I have a requirement, where I need to hide the default method that is getting displayed in the approval task of the workflow.
The employee object and Trip objects default method are getting displayed in the preview of approval task. And same is getting displayed in the universal worklist in the columns of attachments.
There is an option in univesal worklist configuration where we can remove the attachments for display.
But to our requirement , only certain objects and attachments should be shown in portal and R/3 of the approval task.We need to restrict the employee object and trip object which is shown in objects and attachments column of the standard descision task.
Let me have any suggestion on this.
Thanks in advance.
regards,
Sabari Prabhu.

Hi,
I took a look into this same issue some time ago, and at least I didn't find a way to restrict only certain attachments for displaying in UWL. If the attachments cannot be hidden, I have tried to avoid using the business objects as much as possible. For example the employee object is many times binded to the task only because you want to display certain attributes in the task description. Then I have just binded the needed attributes into separate container elements. Of course this will not solve all the cases.
Then other useful options are that you change the default method, and this method is implemented in a way that it either does not display anything, or displays something (maybe just an error message etc.) that makes more sense than the default method that SAP delivers. Or then you can implement for example your own web dynpro application that will be launched when you click the attachment.
