Stale data error for a new page (based on an existing native sshr page)

Without going into too much detail on why I'm doing this, I copied an existing oracle native page, renamed it, and loaded it into the MDS.
I navigate to the page by creating an extension on a controller to take me to there on a button click. Also on this page, the native page that I copied is also accessible. There is a similar button click to take you to the native page.
I had a business requirement to create records for the current year (the native page), and records for next year. Using a dff to differentiate between the two types of records was not an option.
The copied page is used to simply create records. I extended the native controller to default a value behind the scenes (This is how I differentiaing between the current/next year records). The super.ProcessForm/superProcessFormRequest are there as well in this controller. From there, the page is using the same code as the native page that I copied.
When I click the "Save As Draft", "Apply", "Cancel" buttons, it works fine.
However, when I click on the "Apply Add Another" button, I'm getting the following error:
The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example).
Cause:
The record with primary key values {13002} could not be found in view object
AppraisalsAM.ObjectiveEditAM.ObjectivesVO.
To proceed, please select the Home link at the top of the application page to return to the main menu.
Then, access this page again using the application's navigation controls (menu, links, and so on) instead of using the browser's navigation controls like Back and Forward.
I've researched this error all day today on prior postings/threads, and I haven't found a posting that is similar to the one that I outlined.
I wouldn't think I would have to do anything programming wise since this is all native code, and the native page works fine. I'm guessing somewhere the native page is getting reference that is causing this error....
Any help would be appreciated.
Thanks

You could use HIDE/UNHIDE funtionality for page 2
1) create page 2 with all values ...
2) on page 1 - add jJavascript to show or hide Page 2 dependin on value
if (fieldvalue eq "condition") them
Page2.presence = "visible"
else
Page2.presence = "hidden"
endif

  • Unable to resolve stale data error in parent-child page structure.

    Hi Experts!
    I've got a master-detail page which consists of two VOs(EO based), Lets say
    1. MasterTableVO
    2. DetailTableVO
    This page contains two page buttons "Cancel" and "Apply" till here it works all fine & perfect[by that i mean creating, retrieving, querying etc etc.]
    But now i've created another page which is actually a child page of the above mentioned one.
    Here the user'll enter to view some default configured financial info or may also update the default settings manually.
    In this page, I've got only an advancedTable based on a VO(EO based), lets say
    3. PaymentsTableVO
    This page has only one page button "Ok" and which returns back to the parent page retaining the AM.
    All the three VOs are in the same AM. Functionally untill here also it looks fine, but when i finally apply the data it throws an error on getTransaction().commit();
    Error stack:
    OAF Error Unable to perform transaction on the record.
    Cause: The record contains stale data. The record has been modified by another user.
    Action: Cancel the transaction and re-query the record to get the new data.
    Plz reply ASAP.

  • Stale Data Error in seeded OAF page

    Hi All,
    In my custom oaf page I used master-detail between two tables using PPR (with single selection radio button in master table). From time to time I get "Error: Stale Data ..."
    Absolutely the same error I was able to reproduce in seeded oaf page (R12.1.2):
    1. open OA Framework ToolBox Tutorial -> Sample Browser -> Partial Page Rendering (PPR)
    2. expand Coordinate Master Detail Tables
    3. select first record (Supplier Number 1) and wait when the page will be fully refreshed
    4. VERY FAST select second and immediately third record.
    After that I get:
    Error: Stale Data
    The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example).
    Cause:
    The number of displayed records, 3, exceeds the actual number of records, 1, in view object SampleBrowserAM.SupplierSitesVO1. Some of the displayed records may have been deleted
    Additional conditions:
    1. Your connection to server should be "a little slowly" (in my case it's VPN). If apps server is in your local network you can get response very fast and will not get error. In this case repate 1-4 several times.
    2. Browser - IE7 or IE8. In FireFox 3.6 works fine.
    Thanks in advance.
    Regards,
    Sergey

    Hi
    Are you using
    if (!vo.isPreparedForExecution()) if (! vo.isPreparedForExecution ())
    vo.executeQuery(); vo.executeQuery ();
    for VOs in process request of base page!For detailed explanation on this look at this thread: for VOs in process request of base page.
    Please refer this thread may be it help you out..

  • Stale data error while opening a multiple OAF page .

    Dear Friends ,
    I have a OAF page developed and deployed in server , its basically a search page , it also has several links to
    go to create page and update page . when the user opens the multiple page using different tabs in the browser
    like for example
    ex :
    from search page click on create page open it as new tab . if such multiple table are being opened
    and do some operation like search a record , it gives and error (stale data : Developer's mode exception ) .
    How to over come this exception , could you please share you ideas
    Thanks in Advance,
    Keerthi.k

    Hi friend ,
    In Search page i didn't do any update. and also search page is not a problem it's working fine. create page only the problem. In this page only throwing Stale data error exception.
    Please give me more suggestion.
    Thanks in advance,

  • Stale Data error when invoking seeded OAF from a custom OAF page

    Hi All,
    We have a requirement in OAF where we have to open a Seeded OAF Page (Install Base) from our Custom Page. We are using the javascript function “openWindow()” to open the page in a new window. When we close the seeded page by clicking seeded page window using the Window-close button and then perform any event on the custom page, we get the Stale Data error as given below.
    Error: Stale Data
    The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example).
    Cause:
    The number of displayed records, 2, exceeds the actual number of records, 1, in view object OwqAM.IKNCICOWQDetailVO1. Some of the displayed records may have been deleted.
    Here is the part of code we have tried.
    String destination = "/OA_HTML/RF.jsp?function_id="+Func_Id+"&"+"resp_id="+Resp_id+"&"+"resp_appl_id="+Application_id+"&security_group_id=0&lang_code=US";
    String testDest = "javascript:openWindow(top,'"+destination+"',null,{width:750, height:550},false,'document',null);void(0);";
    OABodyBean bodyBean = (OABodyBean)pageContext.getRootWebBean();
    bodyBean.setOnLoad(testDest);
    Also this issue is encountered only when we open an OAF page in a new window. We also have a functionality where a JSP page is opened on similar lines, but above said navigations do not result in the same error.
    If anyone has come across such a issue and have a resolution, please let me know. Any pointers would be of great help.
    Thanks,
    Mrugesh

    Hi,
    We had tried passing RetainAM = Y and then bouncing apache. Still we were getting the same error.
    We are not facing the STALE DATA issue when we invoke JSP page and oracle forms. It is only when we launch a seeded OAF page from our custom OAF page that we are getting this error.

  • Stale Data Error - iProcurement Receiving Page

    Hi,
    I created a button on the Standard iProc Receving Page result table region. When user hit on button it popup window using javascript:window.open(<Page info & Properties>). I am using popwindow to capture some details, and saving into database. But when i am closing and coming back to my main page(Recieiving Page) and navigating to next page it is giving me the Stale Data Error.
    Interstingly this error does not come when the search is done using reqeustor or if i dont click on button for popup window. All other cases gives me this error. One info about this page is the VO which is showing in error should not execute all the time. There are lot of VO's which execute based on search fields entered. The VO belowi s one of them when reqeustor info is given in search fields.
    Error: Stale Data
    The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example).
    Cause:
    The number of displayed records, 25, exceeds the actual number of records, 0, in view object ReceiveItemsAM.ReceiveMyItemsVO. Some of the displayed records may have been deleted.
    Any pointers will be appreciated.
    Thanks & Regards,

    Hi
    Generally Oracle provide a global variable hr_general.g_data_migrator_mode and passing this as 'Y' should update who columns and object version number. But I am not sure it is available for vacancy APIs or not. I remember a similar kind of bug logged long time back.

  • Stale data error while deleting a record

    Hi
    My design of this development is as follow...
    1. Search Page in which users give some search criteria and results will be displayed in the results region on the same page. For each results record I have two buttons like 'Update' and 'Delete' so that users can delete the record or can update the record. For update i created a one more page where users can able to edit and save the data. I have two AM one for Search Page and one for Update Page.
    Please find more details below.
    intfEO  based on PO_REQUISITIONS_INTERFACE_ALL
    errorEO  based on PO_INTERFACE_ERRORS
    updateEO based on PO_REQUISITIONS_INTERFACE_ALL
    VOs
    intfVO based on intfEO and errorEO
    updateVO based on updateEO
    AM
    intfAM based on intfVO
    updateAM based on updateVO
    Pages
    searchPG based on intfAM
    updatePG based on updateAM
    Suppose I have one record in interface table with corresponding error record in error table.When users given the search criteria and hit enter they found a record. It means i have one record in the interface having one error record in the error table and both tables have same transaction id (primary key). So here user first try to update the record and it is working. After update he try to delete a record then I am getting below error. Please note that I am not getting this error when if i directly delete the record with out doing any update before delete. When ever users click on update icon then update PG will open and when users click on Apply button then data is getting updated in the database and page will forward to the search page.
    Unable to perform transaction on the record.
    Cause: The record contains stale data. The record has been modified by another user.
    Action: Cancel the transaction and re-query the record to get the new data.

    Hi friend ,
    In Search page i didn't do any update. and also search page is not a problem it's working fine. create page only the problem. In this page only throwing Stale data error exception.
    Please give me more suggestion.
    Thanks in advance,

  • Stale Data Error

    Hi,
    We have a page developed in OA Framework which displays the JTF tasks which loads 10 records initially and has Next button to navigate to the next set of records. The page has singleSelection table which is used to select a particular record. This page has some fields which can be modified (say status of the task etc). From this page user is allowed to open any e-Business suite applications (like Contracts Authoring form etc). Form based applications are opened using a intermediate page which manipulates the form name etc and uses pageContext.forwardImmediatelyToForm to open a particular form. This intermediate page has a close button which just closes the form. We are getting the "Stale Data Error message" during the below navigation.
    1. Open the initial page.
    2. Click on Next to navigate to next set of records.
    3. Select a record using the radion button.
    4. Select the e-Business form you want to open and click on Go, which opens the intermedidate page and the desired form.
    5. Close the e-Business form and the intermediate page.
    6. In the initial page, change the status of the above selected record.
    We get the "Stale data error" page. Also sometimes, we get this error after doing step 6 above, click on Save button available.
    Any pointers on this would be of great help.
    Thanks,
    Shree

    Hi Shree,
    When you query a table, OA Framework calls processFormData on OAAdvancedTableBean, which in turn performs a primary key check between the rows currently displayed in the table and the rows in the view object result set. If a primary key check fails, a stale data error is thrown. In the case of a read-only table that has previously displayed search results, a stale data error is an indication that the submitted table rows from the displayed page cached by the browser and the latest view object rows are based on different query criteria
    To avoid stale data checks for read-only tables use the following API on OAAdvancedTableBean:
    setSkipProcessFormData(pageContext, true);
    Warning: Do not call this method on updatable tables, as setting skipProcessFormData to true will clear all the changes done on the table.
    Hope this helps.
    thanks,

  • Getting Stale Data error in show/hide of Advance table

    Hi,
    Am using hide/show in advance table.If open the hide/show in 1st row then it shows correct data ,if i click the next row's show hide then its shows the same result as ist row, and i try to use show/hide link more thann three times then it throws stale data error given below.
    The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example).
    Cause:
    The record with primary key values {1400} could not be found in view object MisForecastHeadOfiiceAM.InnerTableVO_OuterInnerVL_InnerTableVO.
    To proceed, please select the Home link at the top of the application page to return to the main menu. Then, access this page again using the application's navigation controls (menu, links, and so on) instead of using the browser's navigation controls like Back and Forward.
    This problem doen't exsist when i deplo it to the server.
    But recently i marked if open a show/hide link of a row and add then add another row to the table and save.Then the same problem reflects in the instance also.
    What may be the possible cause.
    Thanks

    if i click the next row's show hide then its shows the same result as ist row, and i try to use show/hide link more thann three times then it throws stale data error given below.
    >>> Seems like your VO linking is not proper. Does your VO have primary keys defined? Do you have any custom code on these VO?

  • Stale Date Error in Advance Table...Its Very Urgent

    Hi All,
    I am getting stale data in Advance Table Regions. I am having to buttons, if I selected button1 it shows one advance table region (with show All and Hide All options) it is showing correct data in the details view.
    If I select button2 and new advance table will be shown (with show All and Hide All options) and here if I select show all then I am getting stale data. For both advance tables I am using same two VO's (HeaderVO & DetailVO) but the Viewlinks are different.
    For your reference below is the error.
    Cause:
    The number of displayed records, 8, exceeds the actual number of records, 1, in view object NetAppsProjCreationAM.ProjectLinesVO1_ProjectErrorVL_ProjectLinesVO. Some of the displayed records may have been deleted.
    Please any one of you guys help me out in this issue, this is very urgent!!
    Thanks in Advance.

    Then it should work, can you check by putting debugging messages that your VO query is fetching rows properly?Also make sure that all transient columns attributes in VO wizard are not marked selected in query!

  • Should we really go for bean data controls for a new project?

    Hi,
    I am still new data controls and trying to figure out the advantages of using bean data controls for our new project. Our UI is going to have customized UI components and our back end is going to be a tcp/ip server.
    Is it a good idea to develop java beans and then create data controls to bind to UI layer? I think it makes sense to use data controls if we want to use existing java beans. Maybe we would be separating the model layer by using data controls, but only thing it would be doing for us would be the simple object calls to my java beans. Would it be better to use data controls or use I choose to make object calls?
    Thanks,
    Manoj

    Hi,
    the POJO data control will always give you a benefit and develope productivity, unless what you have to build fits on a single page - in which case you may not mind the burdon of manual UI component binding

  • Stale Data Error only Resolved by selecting "Use Update Batching"

    Hello,
    I'm having an issue after creating an update page in OAF.  The page only works when I select update batching within my EO.  The problem with this is my page is using a column type of BLOB which greys out the option to use update batching.  I have tried everything I can think of as well as search on every possible topic over the internet to resolve this issue.  Can't seem to figure it out.  It has become very frustrating as to why I can only update the table by selecting update batching.  Does anyone know how to overcome this issue?
    Thanks,
    Jeff

    I resolved this issue.  The reason I was receiving the stale data error was due to a custom table I created getting corrupted when adding the primary key through SQL Developer instead of doing coding it.  After I recreated the table the stale data error stopped displaying.  Hope this helps people in the future.  Just remember to code the table creation instead of creating it through SQL Developer.
