Prevent that error messages are displayed twice

Hi All!
How can I prevent that error messages are displayed twice.
The FuBa is called at the backend more than one time (at least twice)
therefore I get every message twice.

Sas-
I'm not sure if I understood your problem. Are you saying that you have a service which you call in a loop, and display the error message in the loop as well? If so an option would be to have a [HashMap|http://java.sun.com/j2se/1.4.2/docs/api/java/util/HashMap.html] where the key is the error message id, and the value is the error message. In the loop check if the error message id returned by your service already exists in the map and add it only if absent. Then after your loop is complete use the MessageManager to display your consolidated error messages.

  • Error messages are displayed when opening the RTV form.

    Hi All,
    While doing a return to vendor the following error messages are displayed.
    1.Go to the Inventory Management --> Return to Vendor screen.
    2. In Action Drop down select ‘New’ and click on OK
    3. A series of errors are encountered.
    4. A warning message as [640+49> 688] and then click ‘OK’.
    5. Notice the error message”Multi view internal error: B_RTV_DETAIL.QTY_RETURNED:current_col_pos exceeds parameter defined maximum right position” and then click’ OK’.
    Can any one help me out in these?
    Thanks,
    Sushanth.D

    This is a coding issue in the form, maybe the number is too big for the box on the canvas.
    It looks also like a business issue is kicking off the error, the message [640+49> 688] looks like some units of stock etc. check, e.g. the returned quantity is larger than the stock on hand.
    File an SR with OracleSupport and/or open the UI's Form fmb code in Forms Developer.
    Multi View relates to an (quite old) OracleRetail (Retek) Forms pll library that enhances the Forms features, if my memory is not letting me down.

  • What error messages are displayed to a different program when login fails

    I am trying to use an LDAP Realm and iPlanet Directory server for authentication with WebLogic 6.1. When I try to authenticate to the WebLogic server using an account with an expired password, I get only a Login Exception.
    My question is is there any method to get back a more meaningful message when the password is expired or the account is locked or other situations similar to that so I can throw back an appropriate message to the user.
    I am not sure if this message is appropriate to be posted in this forum, but any help would be really appreciated.

  • WHy can I no longer open multiple tabs; whenever I try each tab is opened but no page is downloaded but no error messages are displayed

    Each tab displays the usual rotational 'downloading' icon but even if I wait several minutes nothing happens.....
    Even if I halt all or close all tabs bar one I am no longer able to download any pages unless I close Firefox completely and restart.
    Upon restart I can then open tabs slowly one at a time but if more than one of my open tabs tries to update similtaneously then the problem reoccurs and I have to restart Firefox once again.
    I have tried removing & reinstalling Firefox as well as creating an all new profile (importing only bookmarks) with no change

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • JSF: Error Message are not getting cleared

    Hi,
    I am facing some problem with error messages in JSF.
    Here is what I am doing
    1. User submits a form, server validates and sends back the error to the client error message added to Faces Context.
    2. User checks the messages, changes the input and submits. assuming everything is correct now.
    3. On server, it validates and writes data to response for download using the following code.
    FacesContext faces = FacesContext.getCurrentInstance();
        HttpServletResponse response = (HttpServletResponse)faces.getExternalContext().getResponse();
        DownloadResponse.sendDownload( response, is, fileName );
        faces.responseComplete();
      }4. It shows the download popup to download the file. The problem here is that error message are not getting cleared off. User can still see the error message on the screen.
    It seems I am missing something in JSF req-response life cycle. Anyone please point out the mistake.

The problem is that the view is not rerendered, which makes sense because you are not sending view content to the browser but your file.
    Your real question probably is: how do I cause a file download and still rerender the view afterwards to show the results? To that I myself do not have the answer unfortunately, but I have seen that question come by a few times already, so doing some searches in these forums may yield you an answer.

  • Bound error message always shown twice?

    In my project every input field is bound to its own message-component.
    But if I start the project and the validator finds an error, all the error-messages are shown twice and I have no idea why! I checked the error-messages in the beans, there is everything ok.
    Does anybody know how to solve the problem?
    Thanks!

    thanks for the feedback.
    @ Darryl.Burke
    Your suggestion sounds quite good, but I can not imagine how this could work.
    You wrote:
    call requestFocusInWindow on the next component in the traversal cycleTo clearify my needs: I want to ensure for e.g. the JTextfield "dateTxt" a verification (starting my methode checkDate()) for the following cases:
    - verify the user-input after leaving the JTextfield via "pressing the TAB-key" (in other words loosing the focus) or
    - start a verification after "pressing ENTER-key".
    I?m not sure, wether these needs are practical with your suggestion...Do you have any code example of your solution? So I can better understand your idea...

  • How to get DML error message to display

    Hi -- I have a report/form combination. When the user creates a record in the form, or cancels, the app branches back to the report results, properly displaying the success or error message from the form page.
    When the user updates or deletes a record in the form, a second form is branched to. This form (a dynamic form), allows the user to enter a comment for deleted or updated records, which are archived to a separate table. The success and error messages are set in this form to an app item called DML_RETURN_MSG. The page process that saves the archive comment sets the value of DML_RETURN_MSG properly: it is visible in the session state.
    This form then branches back to the report results, but the DML_RETURN_MSG is not displayed. I've compared the definition of both forms very closely, and see nothing obvious that would be causing this.
    Is the problem that the first form is a DML form, while the second is dynamic? How can I get the DML_RETURN_MSG to display?
    Thanks,
    Carol

    Carol,
    How are you referencing the DML_RETURN_MSG item in the (success? or error?) message? This is done by enclosing the item name in ampersand and period:
    This is a success message: &DML_RETURN_MSG.
    However, I assume you already know that.

    CRM 7.
    I was planning on performing a restore of the CRM dev system from the previous day, but then discovered that the Repository.xml was missing, or almost empty. This was the SAP standard .xml file, so I copied/pasted from our Sandpit CRM system, then everything worked. That may not have fixed the problem completely though, I'm just trying to see if there are any more issues. One of the symptoms was that when I entered the BSP component workbench there was no BOL Model Browser tab, but the Component structure browser and Runtime Repository editor was there.
    I'll check everything now and will ensure that all is okay, but on the plus side we can now display the factsheet in full within the UI with no errors. I'm beginning to think that perhaps CRM 7 is not as stable as I first thought. What action would blitz the Repository in this way and leave you with a non-working system I wonder. Also, at what point does the repository.xml get updated when changes are made, like when new viewsets added etc.

  • How do I stop security error messages being displayed?

    Multiple messages are displayed when I'm in hotmail saying "Due to Mozilla's security features a link was blocked" etc. It says there was a security error and gives long references. I have to close these messages down before my page will load properly, otherwise the page width is extended and I have to scroll to see things.

    Hi,
    I have a smiliar problem. And I wish I had an answer to yours! It seems that nobody knows the answer! I want to change the mobile phone number which people see when I send txt messages over skype. It confuses people when they see my Australian number (the one originally registered in skype) when I am overseas, people always think I am in Australia. The problem is I can never seem to remove that number I originally used when I set up skype a few years ago. I have changed every instance in skype (profile page etc) where the number appeared but it still displays when I send messages... Anyone know?? Thanks!

  • IPhoto error message, wont display on my iMac G4 iPhoto4.0.3

    I took a Pro Care lesson today so that I could transfer pictures I had placed on my wife's lap-top iBook to my iMac. It was told to burn the photos to a disc and run the disc on my iMac. Unfortunately my computer had an older version of iPhoto. The disc would not run on my machine and an error note appeared stating that I needed to get a newer version of iPhoto. Now I cannot even display my library and an error message appears saying that since I changed something (the only change was trying to run the disc) I would now need a newer version of iPhoto to display my library. Is there any way to go back to my library and any other way to transfer the pictures on my wife's machine to mine?

    Marvw,
    Remove the disc from your iMac. Quit iPhoto. In Finder, look in Home/ Library/ Preferences for a file called com.apple.iPhoto.plist. Move it to your trash. Launch iPhoto. Does your library open normally?
    If so, skip this paragraph. If not, close iPhoto. Hold down the Shift and Option keys while launching iPhoto. Do not release until you can confirm the intent to rebuild. Click "yes," then wait for it to work. Does your library open after the rebuild?
    If not, you'll have to do a manual rebuild. Do you have a backup of your library?
    That error message often comes up when trying to import with a disc in your disc drive. What you can do is leave iPhoto closed and copy the disc to the desktop on your hard drive. Then remove the disc from the disc drive. iPhoto is not forward compatible, so your older version can't read the library created by the newer version. You will have to take your wife's pictures from the library and import them into your library. Her Albums, keywords, titles, and other metadata will not transfer to your library. Do not import items inside the folder called "Thumbs" or "Thumbnails" because they are smaller versions of photos in her library.
    Since you want your wife's photos in your older iPhoto library, there is an easier way to make the disc. On her iBook, select all the photos in her library. Then Export them to a folder on her desktop. Use the Finder to burn that folder of photos to the disc. This will give you just the full-sized, edited (if there is an edited version) photos from her library. You can then import them to your iMac's library. If iPhoto won't import directly from the disc, copy it to your desktop, remove the disc, and import from that folder.
    Post back with results, and we'll go from there.

  • No error message is displayed while deleting an attendee from a course.

    Hi Experts,
    Mu customer is facing problem while trying to delete an attendee from a course under Training and event management. The path he is following is right:
    1) In PSV1(Dynamic Attendance Menu)the employee is seen firmly booked in
    a course.
    2)Right-click on his name and select cancel
    3)Click the dustbin to remove
    But nothing is happening, neither the employee is getting moved from the course nor any error message is displaying giving us any indication of what can go wrong. Can you please suggest what can be the possible problem?
    Strangest thing is, this problem is occuring only for one employee.
    Thanks and Regards,
    Toa

    Hi Manoj,
    Thanks for your reply.
    That is the problem, no error message is showing. When the delete button is pressed, neither the attendee is getting deleted nor any error message is displaying as of why the deletion is not occuring.
    FYI: The employee is not locked.
    Thanks,

  • Floor Plan Manager Webdynpro Java Application : Error Message area change

    Hello Experts,
                             We have a Java Webdynpro Application inside the  ESS business package ,delivered by SAP .
    Is there anyway we can control the Error message area at the top of the Java webdynpro applications using the configuration controller without changing the source code for a particular Java webdynpro application???
    I like to bold the error messsage and change the text color in the SAP Portal.
    If not possible using the configuration controller, what are steps that we need follow to do this change.
    Any help will be appreciated.
    Thanks,
    Greetson

    This cannot be done through personalization or any configuration.
    If you want to change look and feel of error message then assuming these are personal information applications....you will be required to make changes to ess~per DC in NWDI or application specific DC in NWDI.
    Still I believe...in web dynpro java....it will not be possible to change look and feel of standard error message area
