BUG? Data Action on Struts changing to Data page when i reload Jdev????

Hi All,
i'm using jdev 10.1.2, adf bc's, struts, jsp's.
I have a data action on my struts page which is bound to a method in the app module. I created a class for this data action which overrides the initialMethodParameters() method and gets the arguments for the method in the app module.
it all works perfectly fine, until i come into work the next day, load up JDev and the data action has now turned into a data page. if i dbl click on it i get the create page dialog, instead of the data action class. obviously when i try run this data action, i get cannot display this page error.
I'm assuming/hoping that this is a bug. can anyone shed any light??
Thanks in advance,
Liz

Hi,
did you open this in the same version of JDeveloper 10.1.2? I remember that there was a change in Struts between JDeveloper versions

  • How do I change the default page when I open a new tab or window?

    <blockquote>Locking duplicate thread.<br>
    Please continue here: [[/questions/872056]]</blockquote>
    I recently downloaded a piece of software to translate languages. I removed the software, but remnants still appear. It changed my homepages (which I was able to change back). But, when I open a new window or tab, the search page associated with this software comes up.

  • How to change the opening page, when we open a new tab?

    When I open a new tab, it opens the babylon search (which is annoying). How to change it to the thumbnail view showing most visited pages?
    PS: I have not installed anything Babylon related to my PC. I checked the control panel nothing Babylon related is there.

  • CANNOT QUERY SAME DETAIL RECORD IN SECOND DATA PAGE

    Hello,
    We created a Master-->DetailOne-->DetailTwo Business Component Diagram. Added two Data Pages (UIX) to Struts Config diagram. First data page contains Master-->DetailOne (One-To-Many) view from Data Control Palette, and the second data page has DetailOne-->DetailTwo (One-To_Many).
    Our intent is for user to pick a DetailOne record from first page and click a link button to load the second data page with same DetailOne record and any DetailTwo records available underneath. Tried adding a DataAction component to the diagram and dragged several Data Control Operations to it. However our second data page does not load the same DetailOne record as the first one. We also tried data linking first page to second. The second datapage does not display the record selected on first data page when clicking on the link button. Uploading screen shots to clarify issue. Please advise if you need
    additional information.
    Thanks, Ali.

    Hi Judy,
    It's been 5-6 months since I've created a Master/Detail APEX application, but I don't remember having to create any special trigger or anything. I created a few maintenance appls over tables I created, and created an inquiry appl using Oracle vendor tables. All of them have worked nicely.
    If the PK/FK's are set up correctly it just works. :-) Like magic. If I recall correctly, as you create the appl you define the the key fields to use. If the tables are defined correctly, and you 'tie' them together using the correct key fields in the application everything should work nicely.

  • Track Changes in Pages when using Voiceover

    Has anyone successfully used theTrack Changes feature in Pages when using Voiceover? I can find out how many changes there are and navigate to them, but it's not good at telling me what the change is so I can decide to accept or reject. Has anyone got any tips for using this feature? I'm using Pages 5.2.

  • Change a label in page when webpart properties are changed

    Hi
    can anyone please tel me how to
    Change label in page when webpart properties are changed
    Nishanthi N

    Hi Nishanthi,
    If it would be a Visual Webpart, then you have to pass webpart property in user control as WP property bag/collection so that you will retrieve it in ascx and assign its value to label on load event.
    Add below code in Webpart:
    [Personalizable(), WebBrowsable, WebDisplayName("City or Town"), Category("Address settings")]
          public String City {
    get; set; }
            protected
    override void CreateChildControls()
            AddressUserControl control = Page.LoadControl(_ascxPath)
    as AddressUserControl;
            if
    (control != null)
                control.WebPart =
    this;
            Controls.Add(control);
    Put this code in your ASCX Control:
    MyWebPartClass ParentWebPart = (MyWebPartClass)this.Parent;
    Use this code in your ASCX methods:
    string webPartProperty = this.ParentWebPart.City;
    Thanks
    Please mark it as Answer if works...

  • Data Action is converting in to data page with  parameter="unknown"

    Hi,
    I have created one DataAction, and drag a method from appmoduleImpl on to the created data action. that method contains one parameter as well.
    Now i want to write code in findForward() method on that action class (from gotoCode menu item). After all, if i rebuild it, it is changing to data page from data action with parameter="unknown" and giving me error. In page flow diagram also its showing data page image with Yellow coloured exclamatory mark on it.
    Anybody have any idea ???

    This is the resultant entry in struts config.xml :
    <action path="/editpage" className="oracle.adf.controller.struts.actions.DataActionMapping" type="com.abc.de.testAction" name="DataForm" parameter="unknown">
    <set-property property="modelReference" value="editpageUIModel"/>

  • To change table data runtime when dropdown item is changed

    I need to display table as per drondown index item selection. Means i have to change table data runtime when dropdown item is changed.Please help me in that .Please provide code for same.
    Regards,

    Hello gurprit Bhatia,
    On the view create a new action. Fill only the Name and Text and leave the other items default.
    In this event you can populate the table fields.
    Bound this newly created action (event) to the onSelect property of the 'DropDownByIndex'.

  • HT201412 After ios7, My iphone4 has gone dead twice in a time frame of around two months...even though its not happening very often but a two month Old phone going dead just after a New update is not acceptable.probably ios7 still has sum bugs dat need to

    After ios7, My iphone4 has gone dead twice in a time frame of around two months...even though its not happening very often but a two month Old phone going dead just after a New update is not acceptable.probably ios7 still has sum bugs dat need to be fixed...Can this bug expected to be fixed in the next update...

    Hi 1283ar.
    Unfortunately, iOS 7 is too hard to push for the iPhone 4 and therefore has a lot of effects turned off to try to get it to run as smoothly as possible.
    However, it becomes better and better with each update coming but it's hard to do anything about the hardware on an already released phones.
    If you still have trouble or think they are too hard. My tip is, if so, to restore your iPhone 4 and make a clean setup with no iCloud backup. But all your photos in a photostream so you can access it later.

  • Change PowerPivot data source when deploying from Dev - Staging - Production

    We have PowerPivot workbooks we store in SharePoint 2013 Libraries. 
    We have a powershell script which automates the deployment of sites and pages. Is there a way using PowerShell (or any scripting language really) to look into the workbook and change the PowerPivot data source when deployment from one environment to
    another? (Dev -> Stage -> Prod) We need to update the workbooks to point to our SSAS cubes Dev -> Stage -> Prod respectively.
    Thank you for any expert advice you may offer,
    Sincerely,
    -Craig

    Basically, it's an excel file (XLSX) file and you can use excel OM for this.
    A simple program (in C# or any language of your choice) can be written to do the following and achieve what you need.
    using XLS = Microsoft.Office.Interop.Excel;
    string info = null;
    XLS.Application application = null;
    try
     application = new XLS.Application();
     var book = application.Workbooks.Open(filepath);
     foreach (XLS.WorkbookConnection wc in book.Connections)
      switch (wc.Type)
       case XLS.XlConnectionType.xlConnectionTypeOLEDB:
        info = wc.Name + " " + wc.OLEDBConnection.Connection.ToString() + "\r\n";
        break;
     book.Close();
    finally
     if (application != null)
      application.Quit();
    Hopefully, this was helpful.

  • Batch change does not change meta data name when exporting or copy

    I use batch change to change the name of an event when photos from more than one source (camera) are imported. When I copy or export the photos the name reverts to the original meta data file. I do this to override duplicate names. For instance photos from two cameras taking pictures of the same event can have identical names such as IMG_0100. Iphoto does not show all the metadata on info but does show the change in the name when viewing info in iphoto.
    Is there some way to permanently change the name on photos using a group or batch method?

    No you're not changing any filenames at all.
    There is no way to change a filename in iPhoto at all. What you with Batch Change is add a Title to the photo. A Title is an entry in the metadata.
    You can set the name of an exported file to be the same as the title, when you export... if you choose that option.
    This User Tip
    https://discussions.apple.com/docs/DOC-4921
    has details of the options in the Export dialogue.
