How to identify new rows in a vo

Hie
using jdev 11g
I am having a eo based vo and this vo is dropped as a adf faces table. After page load the table is populated with pre-existing data.
now i add couple of new rows and may modify one or two pre-existing rows.
Before doing the commit ( using a button ) I want to only print the rows which are modified or newly added.
what is the way to find those rows in the vo?

In your EOImpl, you could override doDml method & check for insert operations to find out the rows that was inserted.
For details, check

    Hi,
    First upload the file into an internal table. If you are using a file that is on application server. Use open dataset and close dataset.
    Then :
    Loop at it.
    *insert or modify as per your requirement.
    Endloop.

  • How to identify migrated rows on a table

    Hi, folks,
    I'm wondering how to identify migrated rows on a table.
    I understand that ANALYZE generates data into CHAINED_ROWS. The Oracle document implies that this table has both CHAINED ROWS and MIGRATED ROWS. FYI:
    http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14231/general.htm#sthref1881
    But how can I tell migrated rows from chained rows.
    Thanks!

  • How to append new row in rowset with parameter?

    Hi,
    In the data input page in prerender method I have this code to filter rowset with non existing id in the table to show empty table on the page:
    try {           
                getSessionBean1().getKoordinatesRowSet().setObject(1, non_existing_id);
            } catch (Exception e) {
                error("klaida koord " + e);
            }After this I have empty table and I want with a button on the page append one or more rows, fill them and save to my db. I try with this code:
    public String addBtn_action() {       
            try {           
                RowKey rk = koordinatesDataProvider.appendRow();           
                koordinatesDataProvider.setCursorRow(rk);                           
            } catch (Exception ex) {
                log("Negaliu prideti eilutes ", ex);
                error(ex.getMessage());
            return null;
        }But new row does not appear. When I remove parameter in RowSet and remove code from prerender method all works fine, but I see all data from the table that was entered before. Like I said - I want to have an empty table and be able to append one or more new rows, fills them and save to my db. How can I resolve this?

    Rui's answer will create copies of the entire table.  There may be times where thsi is what you want, but you asked about creating new rows.  If your new row is a copy of one of your existing rows, then you could use
    _RowName.addInstance(1);
    (the underscore at the beginning invokes the instance manager).  Is this what you're looking for?

  • How to add new row in KL02 trx - Activity type control data

    Hi guys.
    I am not a FI-CO consultant, but I want to add a row since KL02 transaction within a cost center, with a new fiscal year. When you access KL02 (change activity type), you set the activity type, then press Master Data and the basic screen appears. If you press the Display planning control button, you will see the "Display Activity Type Control Data" List. I wanna add a row for a specific cost center here, because the cost center I refer has not 2011 as fiscal year. I tried to use, since basic screen of KL02, use the Change planning control button, but when I set my cost center and 2011 as fiscal year, the Save button is inactive. Furthermore, I tried to press the Period screen and a message appeared "No data has been entered yet". So I dont know how to add one row for a cost center in the Planning control (Activity type control data) list of the KL02 transaction, specifically for an activity type. Do you know? Thanks in advance

    Hi,
    The list of cost centers in which the activity type is planned is given in KL02 under planning data.  In order to add a new cost center to this, you need to enter the activity type in transaction KP26 for a particular year. 
    Goto transaction KP26
    Give version - 0
    from period 1 to 12
    year - 2011
    cost center - mention the cost center
    Activity type - mention activity type
    goto overview screen F5 and add the plan price for the activity in the cost center.  This step will automatically add new row in the activity type control data.
    Hope this helps.
    Thanks,
    Ram

  • How to add new row at the top of the advance table.

    Hi,

    This adds the row at the end. But I want to add the row at the top.
    How to achive this? Please suggest.
    Thanks & Regards,

    Hi,
    Yes you can do it...
    Just set the add Rows automatically property to False of Add Row Button
    and then in processForm Request capture the addRows event
    and invoke a method in AM and then create a new Row in VO.
    Use this code...it will insert row at the top...
    if("addRows".equals(event))
    am.invokeMethod("addrows");
    public void addrows()
    AddressesVOImpl vo1 = getAddressesVO1();
    AddressesVORowImpl row1 = (AddressesVORowImpl)vo1.createRow();
    vo1.insertRowAtRangeIndex(0,row1);
    vo1.setCurrentRow(row1);

  • How to add new rows in Advanced Table along with attribute value?

    Hi,
    I have one advanced table that contain one messageChoice and messageTextInput field.
    I want to add new rows in advanced table. I can able to add rows using the AddMoreRows button in the footer of the advanced table,
    but I want to add attribute value(contactId) each time when new row created.
    contactId I am getting from pageContext.getParameter("contactId")
    How to achive this? Please suggest.
    Thanks & Regards,
    Sunita

    Hi,
    There are two ways to do it.
    1. Use create method of entity object, create method fires whenever you creates new row.
    2. Handle the event raised by addanotherrow button and write logic there to initialize contactid as you are getting contactid from pageContext so I will suggest you to use this method.
    if (tableBean.getName().equals(pageContext.getParameter(SOURCE_PARAM)))
    && ADD_ROWS_EVENT.equals(pageContext.getParameter(EVENT_PARAM)))
    //write your logic here to default the contact id
    Hope this will help.

  • How to insert new row in JTable?

    In my application,I have a jTable. And the form dose not have a Nevigation bar.
    After I retrieve a record into the jTable, I want to add a new row after the retrieved record. But I could not create a new row by pressing the down key at the last row of the jTable(I could do that in Oracle Form). Dose jTabel have such feature as that in Oracle Form? Or I can do that in another way?

    Such a feature is not available, but you could add a key event handler which works its magic when it detects a press on the down arrow key, while the last row is selected. Then you can perform the code to insert a new row.
