Seeing changes to the tables in the application

If I make changes to the tables in the database (eg. through the database connection or in SQLplus), is there a way to propagate these changes though the application? I'm asking because I made a mistake when I designed my tables - I left out a column and some constraint, as well as a comment. For some reason 'refresh' didn't seem to import those changes - I had to disconnect and reconnect to see it in the tables under the connection editor.
And then I couldn't find an easy way to get the changes into my offline DB objects, onto the diagram, the business objects etc. In the end I started over; it seemed easier, but surely there must be a way to 'import' new features into an object from the object it was generated from? If not, I think that would be a great improvement, I can see myself using that more often than I want to admit.

Hi,
actually there is no end-to-end refactoring that propagates database changes up to the view layer. ADF BC for instance allows you to refresh the business service model with changes applied to the database. However, from there on you will need to manually ensure that the changes don't cause naming conflicts

  • Admin can see changes to the page, but User cant see the changes.

    Hi All,
    I am a brand new SharePoint admin for a school. Faculty/Staff access the site collection as well as the students. Faculty and Staff have higher rights than the students, and can add content as well as view them. 
    As the site collection administrator, I have added a html webpart and added html code to a subsite. (the code is simply hyperlinks that route to a different page when clicked, nothing complex).
    I made these changes and can view them properly as the site collection admin when I check in the site. I then signed out as the site collection admin, and signed in using a dummy student account. I went back to the same page where I made the changes, and
    cannot see them. 
    The url of the site is the same for both administrator/student. 
    Please see photos for a better understanding. 
    I want to edit the subsite and make these changes so everyone can see it. 
    This first image is from the administrator's perspective. (As you can see, even the top navigation bar is different as well)
    This second image below is from the student's perspective. (You can see the hyperlinks don't show, and that the top navigation bar is different)

    Hope you have checked-in and published the page...
    If you don't publish the pages, your students may not see the changes.

  • Why has my dashboard icon changed to the application icon

    my dashboard icon has changed in my applications from a speedometer to paper and pencils and i can t change it back no matter what i try.
    can someone please help me figure this out.

    i think the same thing happened to me. When I first got my laptop (a few months ago) the app folder was a baby blue colored folder on the bottom right corner of my dock. It's still there now, but now I also see the same letter "A" in a circle, like the shape of the safari and speedometer, right next to my smiley face3 finder icon. I went to open the "Finder" and immediately noticed the A in the circle just to the right of it that was never there before!!!

  • Has anything changed with the application manager?

    I used to be able to download my applications using the Aplication Manager. However, it no longer available and I guess I need to coome to the Adobe site, sign into my account and download that way. Is this right?

    By no longer available do you mean the Adobe Application Manager (AAM) cannot be found on your system, or that the link for launching it does not work? You should be able to download programs by doing to the Apps & Services page at https://creative.adobe.com/apps and clicking on the Download link for the program you want to install. You can also try uninstalling AAM by going to the Control Panel in Windows or Applications > Utilities > Adobe Installers and uninstalling AAM. Then relaunch your browser if it is running and sign in. You should see the download link for AAM appear again.

  • Every time I click on a link, an OLD version of Firefox keeps opening, I don't know how to eliminate the old version (I don't see it in the applications folder). This hasn't happened with any other upgrades to Firefox. Can you help?

    This happens when I get an email with a link attached. Also, every single time I open up the NEW version, it defaults to the "welcome to Firefox 4" page. Is there a way to make it stop doing that too? Did I just download the new version too soon, before the bugs were worked out?

    Version 3.6.16 is opening....as it did when I clicked the link in your email message to me about this situation. The upgraded version (Firefox4) sits in my dock and the old version opens when I click on a link.

  • Field Values being changed in the flat file on Application Server

    Hi All,
    I am loading a flat file(.CSV) from Application server. The file has some characteristic fields, for ex: CNUM of type Char, length 20. But it has got the value which is of 10 char length, say XYZ1234XAB. When I load the same fiel from client workstation, the load was successful but when I load it from Application server, the load has failed and the error is Invalid/Hex. characteristics for this record and many such records.
    When I checked the file on the application server the value 'XYZ1234XAB' is being displayed as 'XYZ1234XAB   #' and it is also being loaded with '#'. This is the cause of the error.
    Why is the value being changed on the application server? What can I do to overcome this?
    Thanks,

    Hi Ganesh,
    I have already loaded data to my ODS and when activating it is giving error "Value 'XYZ123XABC   #' (hex. '123456....') of characteristic CNUM contains invalid chara".
    I also have some lower case char in some of the records for the same field. The file is huge and cannot change the file, infact I have many such files. Is there any other way to overcome this?

  • How to change podcast settings in the Application options dialog

    I have attempted to subscribe to an RSS feed for a podcast - URL is http://www.abc.net.au/triplej/kingsmill/rss/podcast.xml
    I am being prompted to join using live bookmarks. As i use Google reader, there is no option available to change it to google. Hitting the dropdown arrow, my choices are live bookmarks or Microsoft Outlook - or browse for application. How do i change / remove the applications entry for RSS so i can start over and select Google as a default
    The Options / Application / Podcast - has the RSS logo - says "preview in firefox"

    Apple does not make what you are asking straightforward for a reason: the user usually sets the system language to the one they prefer anyway.
    If you think you have a good reason for setting the language in the application itself, I would suggest using the pathForResource:ofType:inDirectory:forLocalization: method of the main bundle to get the applicable strings file and then deserialize it into a dictionary as if it were a plist (strings files actually are).

  • How can I see changes in table with insertrow();postchanges()without commit

    Hi friends;
    I use jdeveloper 10.1.3.1 with jheadstart 10.1.3.1.
    I create two view object.In the first page I create table with one view object.
    In the second page I create table (with tableselectmany) with other view.
    I select many rows in second page and in the managed bean,
    I insert selectted rows atributes to first pages tables attributes.
    I use this code.
    public String commandbuttonaction(){
    CoreTable table = this.getTable1();
    Set rowSet = table.getSelectionState().getKeySet();
    Iterator rowSetIter = rowSet.iterator();
    BindingContainer bindings = getBindings();
    DCIteratorBinding pr_dcib = (DCIteratorBinding)
    bindings.get("DeptIterator");
    int i=206;
    while (rowSetIter.hasNext()){
    Key key = (Key) rowSetIter.next();
    pr_dcib.setCurrentRowWithKey(key.toStringFormat(true));
    RowImpl prRow = (RowImpl) pr_dcib.getCurrentRow();
    String AM="model.AppModule";
    String CF="AppModuleLocal";
    ApplicationModule empSvc = Configuration.createRootApplicationModule(AM, CF);
    ViewObject emps = empSvc.findViewObject("EmpsView1");
    Row newEmp = emps.createRow();
    newEmp.setAttribute("Manager",new Number(1));
    newEmp.setAttribute("Department",new Number(1));
    newEmp.setAttribute("Depno",new Number(3));
    emps.insertRow(newEmp);
    try {
    newEmp.validate();
    catch (Exception ex) {
    System.out.println("validate catch");
    try {
    empSvc.getTransaction().postChanges();
    catch (Exception ex) {
    System.out.println("post catch");
    Configuration.releaseRootApplicationModule(empSvc,true);
    i=i+1;
    In this code I only postchanges() in first view and dont want to commit.
    But I cant see changes row in the page .If I press save I see transaction completed succesfully message.
    But in database not insertted any rows.
    If I write commit() after postchanges() code I see rows in the table .But I dont want to commit.Only post
    my changes and if necessary I press save button in page.
    How can I see changes in the page without commit???Thanks for all....

    You should NEVER use statements like this in managed beans:
    ApplicationModule empSvc = Configuration.createRootApplicationModule(AM, CF);
    This will create a separate application module instance, not shared by the the web pages. That's why you do not see the changes.
    Instead, you can use the following code:
    ApplicationModule am = (ApplicationModule)JsfUtils.getExpressionValue("#{data.MyAppModuleDataControl.dataProvider}");
    where MyAppModuleDataControl shoud be replaced with the name of your am data control.

  • Big trouble with "The application 'Firefox' can't be opened

    Hello
    I have a big problem. I cannot use firefox, either quit it or use this application. If I want use firefox than I get the Information "The Application firefox can't be opened -600". And also I cannot close my macbook Pro (alas it is a Retina) or trying reboot. It still stands and nothing changing on the desktop from the macbook. I have red some some problems with the probably solutions how can fix it, but I'm afraid about, that I would make a big mistake and destroy the macintosh Marverics System that I have.
    Please. I need help !
    Thank you!
    Canno92

    This Step failed a lots of time. I tried everything in my mind. I tried to do this step you suggest me now, and nothing (some tries before) happened. What can I do to not have the message "the application firefox cannot be opened - 600" ? Its really **** that that happened now..
    I tried to reboot - nothing changed
    I tried quit the application - nothing changed
    I tried to hold he "shut down" button - nothing has changed or has shut down
    I tried go to system preferences/application/ and tried to trash the application - nothing changed, because the application is still working/or in use. And this s*** is really confusing me. Therefore I can not use firefox, not trash the application because it is in use, or either close the application to shut down or restart/reboot my macbook Pro.
    Any other suggestions? If possible, than it would be very kindly.
