Task-flow for inserting a record in a popup: error on primary key.

Hi all,
I am using Jdeveloper 11.1.1.2.
I am trying to display a bounded task flow in a popup launched from a page. I am following the steps in: http://www.oracle.com/technology/products/jdev/tips/fnimphius/popupinuishell/declarative_popup_in_uishell.html
I have a view object (myVO) and I have a page (page1), where I can edit the records of myVO. In this page I have a button that launches (in a window) a task-flow (insertTF, that uses existing transaction if possible, composed by page2 and page3) where I can insert a new record in two step (using a train).
At the end of the train I can save or cancel (task flow return activity) the inserting record.
The button cancel work well, but the button save does not. When I click on it, I return in page1 but I have this error: Error: another user modified row with primary key oracle.jbo.Key [[+numberOfKey+]].
If I see the database navigator or I refresh the page, I can see the record just inserted.
How can I do to remove this error?
Thank you
Andrea

There are default values coming from the DB. There are also default values that I have setted in myModel on myEO.
I am the only user manages the database, there are no other users.
So, how can I solve this problem? Have I to remove the default value on inserting? From DB or from myEO?
thanks in advance

Task-flow for inserting record in a popup

Hi all,
I am using Jdeveloper 11.1.1.0.
I have a page with a lot of panelTabbed that displays a lot of data of a table.
I would like to have a button that show a popup and launch a task-flow for inserting data in the table in more steps.
I have created:
1) one fragments for every inserting step
2) a bounded task-flow having an activity (createInsert before the activities (fragments) to insert a new record), with a task flow return (cancel and commit) to save or rollback the data.
3) obviusly, a button that show the popup for inserting a new record. I have inserted the task-flow defined in 2) as a region in the dialog of my popup.
When I launch my page:
1) I see an empty form (instead of seeing the first record)
2) the data inserting on the popup are not saved
3) the second time I try to launch the popup, I see nothing, only the OK button of the dialog.
I know, in the new version of Jdeveloper it is possible to insert a task flow in a popup, but is it possible, in the previous (my) version?
Thanks
Andrea

1) You are seeing an empty form because you are probably calling CreateInsert method of your data control. You should call it only if you are going to create a new record. Also, if this is a new record, you should not show the tabs below. In my case, i am doing like this:
There are 3 pages, ListPage, CreatePage and Edit Page.
User first enters to List page (because it is the default activity in taskflow), to list Master records in a table. There are also 2 buttons, Create and Edit. If Create button is clicked, CreateInsert method is invoked and then CreatePage is called. In create page, there are only 1 form of Master's attributes. After user commits, taskflow redirects the page back to ListPage.
If user selects a row in list page then press Edit button, EditPage is called, but without calling a CreateInsert method. You don't have to invoke any methods if your table in ListPage has a SelectionListener (which is set by default).
in launch listener, you can run a method like this:
public void saveState(LaunchEvent launchEvent) {
DCIteratorBinding ib = ADFUtils.findIterator("YourMasterIterator");
RequestContext requestContext = RequestContext.getCurrentInstance();
//we save key.
String key = ib.getCurrentRow().getKey().toStringFormat(true);
requestContext.getPageFlowScope().put("yourKey", key);
and in return listener:
public void loadState(ReturnEvent returnEvent) {
RequestContext requestContext = RequestContext.getCurrentInstance();
if (null == requestContext.getPageFlowScope().get("yourKey"))
return;
DCIteratorBinding ib = ADFUtils.findIterator("YourMasterIterator");
if (null != ib)
ib.setCurrentRowWithKey((String)requestContext.getPageFlowScope().get("yourKey"));
You can find ADFUtils.java and JSFUtils.java in Store Front Demo project and some other sample projects.
2) About the X button... This is the biggest problem of inline-popups. As far as i learned from people in this forum, it is not possible to remove that if you use an inline-popup. And it does not invoke returnListener. But, it does a rollback! I think it is a big problem and i am hoping to find a solution too. Using a popup component instead of inline-popup as dialog can be a workaround.

Hi Deniz,
thank you for you reply.
My task flow is sharing data controls with its caller, because main page displays updatable record, while the button launch a task flow in the popup to create a new record of the same table.
I have understood what you are saying (save the current key when I launch the popup and restore the key when I return from the popup), but:
1) when I enter in the main (caller) page, I see an empty form, and not the first record of my table. Why?
2) the returnListener works even if I close the dialog with the "x" (in the up-right angle of the dialog) or only with its buttons?
3) where can I find the code/links/examples/guides to implement launchListener and the returnListener for my button?
Thank you
Andrea

Modify unbounded task flow for login process

I wonder if I can use the unbounded task flow for login process. I have a login page, a home page and a change password page. As per the requirements, I need to show the login page first, if user password is expired, I need to show change password page, after user save the new password, I show the home page. If user password is not expired, then we go to home page directly.
I have modified the unbound task flow adfc-config.xml. I have created a method call, which references a method in my managed bean to check the redirect page. I have created a router, which would go to change password page or the home page based on different outcomes. But the problem is, every time when I run the application, it always goes to the home page directly, even when the user password is already expired. I have set up break point at the checking redirect page method in my managed bean, looks like it never got called.
Did I miss any steps here? Please advise. Thanks.

A method is not a runnable object in your pageflow - so you can't start from it.
You need to start from a page when your run your project.
One option - convert your flow to be a bounded flow with the method as a default URL and then run it.

Start routine for insert a record by each day in a range of dates

Hi all,
I need create a start routine for insert 1 record by each day in a range of dates:
example:
Actual.
DATE_I             DATE_F          TIME_I       TIME_F      TIME_minutes
04/04/2008       05/04/2008     13:40:00     23:00:00        2000
Result:
DATE_I             DATE_F          TIME_I       TIME_F      TIME_minutes
04/04/2008       04/04/2008     13:40:00     24:00:00        X
05/04/2008       05/04/2008     00:00:00     23:00:00        Y
I thanks any help.
regards.
Alberto.

Hi Alberto,
What I understood from your requirement is that you want to split the record into 2 since you have 2 dates coming from the source.
In the transformations you will have to create new rule group one for each of the dates.
You can create the new rule group by clicking on the 'Rule Group' button and then clicking on the 'New Rule Group'.
In the newly created rule groups take care to distribute data for each date separately.
Hope it is clear.
All the best...

Krishna

Create Custom ADF Task Flow for BPM

Hi,
I'm working an project on BPM and I'm required to create a custom ADF task flow with multiple views based on the human tasks in BPM. Since I'm new to ADF, could some one please give me some pointers?
Thanks,
Debojit

Hi,
You have to implement your own custom worklist screens for such a subject. As you know the OOTB worklist screen shows the logged-in users' assigned, etc. tasks. You have to implement the API of SOA workflow.
You can check Mark Nelson's blogs on Redstack to accomplish this. Hope this is the answer of the problem you are looking for.

Create ADF Task Flow for Human task outside of SOA Composite

Hi,
Is there any way you can create ADF Task Flow form (for the task Details to be display in worklistapp) for a Human task out side of the SOA Composite applicaiton?. I know we can create ADF Task flow form for task details based on Human Task in SOA composite application. But I dont want to do that. I dont want to keep any association between Human task and ADF Task Flow.
If there is a way to do this, How can we assiciate this ADF Task flow form with worklist applicaiton?
Thanks

Identify task flow for the request

Hi,
We have a requirement identify for which task flow the new request has come? We have a left navigation bar, where menu links are configured and each menu activates one task flow. When the user clicks on any menu, the corresponding task flow is called. We would like to know in the phase listener to which taskflow the request is coming?
Is there a way to know this? Our application is based on UI shell and when I look for requested URL always the same URL is coming.
Thanks,
Rama

Task flow-call as a Dialog with inline-popup issue JDev 11.1.1.2.0

I have a very serious issue with task flow-call running as a Dialog with inline-popup
have bunch of data driven table components pointing to pageDefs with Iterators
the problem is, the dialog comes first with nothing in it (blank) and it takes 3-5 seconds to fetch all views,
this is useless, there is no option to control taskflow-call activation , like you do for af:region
For reference : I am talking about this : http://jobinesh.blogspot.com/2010/08/refresh-parent-view-when-in-line-popup.html
Download the workspace , connect as HR Schema and you will see what I am talking about
looks really dumb, it would make sense to show dialog with data all at once, rarther than looking at blank screen to wait for the data to show up
Edited by: user626222 on Sep 20, 2010 8:57 AM
can I call this a bug?
Edited by: user626222 on Sep 20, 2010 1:58 PM
sometimes I wonder if anyone tested this, as soon as you have some data driven components on your page, you get all sorts of problems in ADF
But something simple, Adf client side invokes the Dialog as a popup first, and then it thinks oh ya I get massive pageDef to load, so end-user customer will stare at the blank screen for 10 secs , hoping that something will come up or program is crashed
Well, I am afraid to say you lost your customer :(

Sample data above and below is the dataype for each one of them
alpha datatype- string
beta datatype-integer
gamma datatype-integer
col1,col2,col3 are all string datatypes.
Note:columns are not unique and we would be using alpha,beta,gamma to uniquely identify a record .Now as you see my sample data this is in a table which doesnt have index .I would like to have a index created covering these columns (alpha,beta,gamma) .I
beleive that creating clustered index having covering columns will be better.
What would you recommend the index type should be here in this case.Say data volume is 1 milion records and we always use the alpha,beta,gamma columns when we filiter or query records

Many thanks for your explanation .
When I tried querying using the below query on my heap table the sql server suggested to create NON CLUSTERED INDEX INCLUDING columns ,[beta],[gamma] ,[col1]
,[col2] ,[col3]
SELECT [alpha]
,[beta]
,[gamma]
,[col1]
,[col2]
,[col3]
FROM [TEST].[dbo].[Test]
where [alpha]='10100'
My question is why it didn't suggest Clustered INDEX and chose NON clustered index ?

Procedure for inserting a record in HANA

Hi All
I have created a table using .hdbtable definition. I have also created an .xsodata service to fetch the details of the table. The problem is when trying to insert data into the table.
For this, I created a procedure. But when I tried to activate I am getting an error which says "Invalid column name".
But the Column name which is provided is correct.
I am stuck and not able to proceed. Please help.
Thanks in advance
Meenakshi

Hi All
Instead of using a procedure, I tried to achieve the same using server side js. I created a .xsjs file and tried to connect to DB to insert values. But here also no luck. There is an error popping in the insert statement.
Here is the screenshot of the problem. Any suggestions ?

How to genarate Primary Key for each record in XI Mapping

Hi,
I need to genarate primary key for each record in the paylod in mapping..
Eg: if i have a 10 reacords i need to have a primary key for each record..starting with the
Record      Primary key
First            001
Secound      002
Tenth         010
If i need to write any user defined funtion... can any one provide the code for it.
Thanks

Hi Bavesh,
I will explain with the example:
XML:
<Record 1>
<Primary key>
<value1>
<value2>
</Record 1>
<Record 2>
<Primary Key>
</Record 2>
like above i will be getting n number of recored and in each record i need to genarate primary key in XI.and the key sould be in sequence...
like for the first record 1 secound 2 like that primary key should add to the privous Primary key.
and this is for each payload.
Thanks

Edit the task flow which is default in template for top navigation

Hi,
Where can I get the the default task flow file (i. e. spacesNavigationPanel) for collaborative with top navigation template?
I want to edit the task flow for navigation.
Thanks,
A

Here are the steps to find the default task flow file (i. e. spacesNavigationPanel) for collaborative with top navigation template :
Note: I am assuming you're using Oracle WebCenter Portal 11.1.1.8.x
Goto Portal Builder - Assets tab localhost:8888/webcenter/portal/builder/administration/assets
Select Page Templates under Structure from left side pane and you'll see list of out of the box page templates (source not editable) and custom page templates (source editable) on the right side pane.
Take a copy of the existing 'Collaborative with Top Navigation' page template
Select the row 'Collaborative with Top Navigation'
Click on Actions -> Copy
Change the display name (Default : Copy of Collaborative with Top Navigation) and description if needed.
Click OK to create a copy of 'Collaborative with Top Navigation' page template
Select the row w.r.t. newly created page template Copy of 'Collaborative with Top Navigation'
Click the checkbox to make it Available (Optional if you want to use this template later)
Click on Actions -> Edit Source to edit the source of selected page template.
You'll see template code in the window (by default).
Click on 'Page Definition' tab at the bottom of the template code window i.e. Switch to Page Definition tab.
Under Executables, you can see the taskflow code w.r.t. spacesNavigationPanel as follows : <taskFlow id="spacesNavigationPanel" taskFlowId="/oracle/webcenter/webcenterapp/view/taskflows/navigation/SpacesNavigationTopPanelCollaborative.xml#SpacesNavigationTopPanel" Refresh="ifNeeded" activation="deferred" xmlns="http://xmlns.oracle.com/adf/controller/binding"/>
I hope it answers your question.

Best practice question for Bounded task flows

We are new to Jdeveloper/ADF and I was wondering if we should always try to use a bounded task flow for our applications... is this considered the best way to develop an app? even the small single page ones?
Thanks in advance.

Hi,
let me turn teh question around: How many tools do you have at home beside of a hammer ? In other words, its the problem you need to solve (and use cases are problems) that should determine the use of bounded task flows and its granularity. Note that for each use case the bounded task flow makes a good candidate for delivering it. Doesn't mean that every single page needs to go into its own task flow. For general bounded best practices have a look here
