How can I get the previous record's field value in a VO

Hi I would like to know how can I get the previous record's field value in a VO
For example : I have a VO porequisitionlinesvoimpl, and it contains 5 records (porequisitionlinesvoimpl.getRowCount() = 5). How can I search all records in the VO and get the field (attribute3) for all records?
Many thanks anyone can help
Lawrence

Hi ,
U can loop through the VO to get the value of attribute3,
need to extend the controller ,use below code
OAViewObject vo = (OAViewObject)oawebbean.getApplicationModule (VO1);
OARow row = null;
int fetchedRowCount = vo.getFetchedRowCount();
RowSetIterator Iter = vo.createRowSetIterator("Iter");
if (fetchedRowCount > 0)
Iter .setRangeStart(0);
Iter .setRangeSize(fetchedRowCount);
for (int i = 0; i < fetchedRowCount; i++)
row = (OARow)Iter .getRowAtRangeIndex(i);
String value = (String)row.getAttribute("Atrribute3");
Thanks
Pratap

  • How can i get the previous version of iTunes back

    I have a MacBook with a DVD/CD drive, Mac OS X (10.7.5). I recently updated to iTunes version 12.0.1.26. It seems to be designed for Macs without a DVD/CD drive. How can I get the previous version back? I don't have a back up or use time machine.

    Thanks Chris, there a number of problems I'm experiencing. When I insert a CD, despite the preference being ticked, I nolonger get the box that asks me if I want to import. When I did manage to import I couldn't find where the file had gone. Perhaps what I need is a good user guide for the latest version of iTunes because at this point the impression I have is unless I'm buying from iTunes nothing seems to work as it previously did. It is impossible to add anything to my library.
    I'd be the first to admit I'm no computer nerd and all the information I've found so far to try and sort out my difficulties don't seem to work. Can someone please tell me where can I get a good user guide for iTune 12.0.1.26 because I find it far from intuitive? At least then I have a chance of working out if it's me or the machine.
    Many thanks in anticipation.

    You don't want to maintain a reference to the last selected node, but to the last selected path. Nodes within a tree are addressed using a TreePath, with contains references to each node from the root, down to a specific node. Look at the JavaDocs of javax.swing.tree.TreePath for more info.
    Also, JTree has getter/setter methods for the selectionPath.

  • We are upgrading from 8.3 to 9.2. How can i get the table(record) structure changes between these 2 version

    We are upgrading from 8.3 to 9.2. How can i get the table(record) structure changes between these 2 versions. I am not able to find it in Oracle support.

    My guess is you want to upgrade HR8.3 to 9.2 - and that is not one jump upgrade. You will need to go HRMS 83 to 90
    (PeopleSoft Enterprise HRMS 8.3x to 9.0 Upgrade (Doc ID 747333.1) and then 90 to 92 (PeopleSoft Human Capital Management 9.0 to 9.2 Upgrade Home Page (Doc ID 1536087.1)
    Each these MOS pages contains the Demo to Demo Compare Reports that show the data structures changes between the releases.
    Hope it helps.

  • How can i get the previous date?

    Hi,
    I am entering a future date(xx-xx-xxxx) through my application.I need to perform some actions on the previous date of the entered date(xx-xx-xxxx).How can i get that previous date?

    Oh dear god.
    Parse the date using SimpleDateFormat. You can then use Calendar's setTime to set a Calendar instance to your date, and use add(Calendar.DAY_OF_MONTH, -1) to substract a day. getTime() will then provide a new Date. And yes, look it up in the API docs.

  • How can I get the previous clicked node in a Tree?

    I have a JTree. If a node is selected, before the user select another, I need to make a question if he have sure about the new selection.
    If the user answers not, I need to select the previous node.
    I have in my class a variable, type of DefaultMutableTreeNode, that makes reference to the last node selected.
    How can I turn this node selected again, if the user select "No"?
    Thanks for any help.

  • How can I get the previous version of flash? pre 11.1.102.62

    Lion OSX 10.7.3
    Firefox 10.0.2 or Safari Version 5.1.3 (7534.53.10)
    11.1.102.62 or 11.1.102.64
    I keep looking on the site and I cannot find a prior version to 11.1.102.62; I can only find 11.1.102.64 and 10.1.102.64 nothing in between.
    I am trying to troubleshoot.
    Flash worked just fine on a computer with all of the same hardware a week ago, different computer that has been sent back so I cannot look at the software versions. I know that it was running the previous version of flash at least one release befor .62. All of the same issues occur with .64
    Examples of issues:
    (Below describes issues on Firefox, similar issues on Safari)
    http://www.tonypa.pri.ee/blockarelli.html
    It says "WELCOME 0123456789" at the top and whe you click on the game to play it you cannot do anything it just gives a dotted outline to the game.
    http://www.tonypa.pri.ee/cobacoli.html
    If you play level one and finish level one then starts over, if you finish level one agian it does nothing the screen does not change.
    On stage select to play menu all levels and level score show as "88" (should be 1, 2, 3, etc. and then no score until played)
    Simiarly to cobacoli
    http://armorgames.com/play/11711/the-adventures-of-dear-explorer
    It loads to main screen and all menu buttons show as "#Type1#" Should be something like Play, continue, settings, etc.
    http://www.tonypa.pri.ee/taberinos.html
    Once you finish the game the highscore list never comes up, the game just ends; the game does not restart.
    The same happens here http://www.tonypa.pri.ee/turnellio.html
    http://www.kongregate.com/games/mofunzone/zombie-exterminator
    It just plays the mofunzone intro over and over again
    Hulu videos have a decent amount of blank time before loading the ad. They do have a problem continuing to play when skipping around; I often have to click a couple different spots in the track before it starts playing again.
    If you load this game the Armor logo plays, then the alillm.com plays then the game is just black
    armorgames.com/play/11758/hazmat
    Youtube videos on youtube seem to play fine on this computer. Everything to do with flash .62 works well on my other machine running snow leopard.

  • After going through the process for an upgrade, we completely lost Mozilla. We get a message saying that we don't have permissions. How can I get the previous version back on my computer?

    My husband received a message saying that there was an upgrade for FF Mozilla, so he proceeded to upgrade. After doing so he received a message saying we didn't have permissions. I took the laptop to the Geeks at Best Buy and was told that it was a software issue. We just want to get back to our previous version but can't do that either.

    Do a clean (re-)install:
    * Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
    * Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    * Do not remove personal data if you uninstall the current version.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • How can I get the previous version of Acrobat back?

    The new DC version is **** and keeps crashing itself and the program I'm printing from when I print to PDF which has wasted too much of my time.  I'm using CC and can't see an option to reinstall a previous version.

    Uninstall, and go here for previous versions of Acrobat Reader.
