Final view and window relation?

Hello,
I am checking a existing custom webdynpro component in the system (ADS is not up, hence am unable to play around with it!), the views and window is,
INITIAL_VIEW
DISPLAY_OUTPUT_VIEW
MY_WINDOW, the inbound & outbound plugs are defined as,
INITIAL_VIEW <--------- > DISPLAY_OUTPUT_VIEW  <--------------  MY_WINDOW
                            (1)                      (2)  
Pls. let me know , 1) We are displaying our data output in the DISPLAY_OUTPUT_VIEW, which means in the MY_WINDOW, so, then, why  do we need the navigation from my_window to display_output_view as shown in the (2)? display_output_view is nothing but my_window right?
2) And I also saw some good amount of custom coding in the Event Handler of u2019HANDLEFROM_WINDOWu2019, at what point this code triggers?
3) I saw an Inbound plug for MY_WINDOW with the name of DEFAULT, when this will trigger?
Thank you.

Hi,
For your third question
I saw an Inbound plug for MY_WINDOW with the name of DEFAULT, when this will trigger?
Just double click on the Webdynpro application(WDA) , the interface view specified is your window and plug name specified is same as the one you found in window.
When you start a WDA ,it triggers a window through the plug default and the window will have a view as default and that particular view will be shown.
For your First question
You need a navigation from initial view to display output view and may be viseversa . A navigation plug is just a relation.It will be triggered from your code(fire_plug).
For your second question
You have a event Handlefromwindow ,so there should be a Plug From Window(I guess there are two windows,each view in each window )..and when the navigation is coming to current window handlefromwindow triggers.keep break point and look.
Provide more information , if you have further doubts.

  • Difference between view and window ?

    Hi All,
    Can you tell me a basic difference between view and window , maybe you can correlate your answers with concepts of HTML.
    Rajeev

    Hi Rajeev,
    A window is a place for displaying your views. Your view is not available to the outside world. View is available only to your component. However, your window is an interface view, which can be displayed in other components.
    A view contains your UI elements. It has a layout (a window does not). A window contains embedded views.
    In the window, you can define how navigation between views takes place (by creating navigation links).

  • Crystal Report Viewer and Windows Vista

    Hi,
    We are using RDC methodology for launching the crystal reports in the web using ASP.
    The web server operating system is Windows 2003, Crystal Reports XI is installed in it.  Report is not launching in only one client machine.  For all the other client machines reports are launching perfectly.  The problem is blank white activex control is displayed.  I tried to register the crystal reports viewer (ActiveXViewer.cab available in the crystal installation folder) deliverables in the client machine but after installing the deliverables same problem persists.
    When I click on the Crystal Report viewer Internet Explorer Exception occurs
    The following add-on was running when this problem occurred:

    Could any one help me regarding this.

    Hello,
    First thing to do is upgrade to [CR XI R2 SP4 full build|https://smpdl.sap-ag.de/~sapidp/012002523100011802732008E/crxir2_sp4_full_build.exe]. Then get up to Service Pack 6 and you should not have problems with Vista.
    CR XI R1 will not and has never been tested on that OS.
    If you do not want to upgrade though use Process Monitor to watch for Access Denied errors. Also run IE in Compatibility mode.
    Likely what is happening is your test PC doesn't have rights to install ActiveX controls.
    Thank you

  • Wd Quick View and Windows 10

    I use a My Book LIve Duo and the WD Quick View app sat on my toolbar, It gave me easy acces to my NAS. Since changing to Windows 10 (from 8.1), the app is still there but only gives an exit option and a WD logo info thing, with no access to my NAS. I've tried reloading but to no avail. Any one else have the same problem (or solved it!)?

    Hi there, welcome to the community.
    The WD quick view is not yet compatible with Windows 10, you can see the supported operating systems on this link.
    However, have you tried running the application in compatibility mode?

  • Crystal Report Viewer and Windows 7 Enterprise

    Hi,
    We are using RDC methodology for launching the crystal reports in the web using ASP. 
    The web server operating server is Windows 2003, Crystal Reports XI Release 2 is installed in it. Activex Viewer is downloading fine in client machine having Windows XP OS (IE Version is 7) but for the same url ActiveXViewer.cab is not getting downloaded in Windows 7 Enterprise (IE Version is 8).  It throws the error u201CThe Crystal Report Viewer is unable to create its resource objects.u201D
    To download the cab file in Windows 7 machine it request for the following url
    1.     http://<web server name>/crystalreportviewers115/ActiveXControls/ActiveXViewer.cab
    2.     http://crl.verisign.com/pca3.crl

    4.     http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab
    URL 2,3,4 returns the http status as 502 (Bad gateway).  These url are not called from the Windows XP machine.
    The windows 7 client machine is not connected to the internet. I tried importing the crl files (by downloading from another machine).  But still we are getting the same error.
    How to over come this issue?
    Please Note :
    1. I am able to download the cab file when I tried to download only the cab file directly by specifying the cab url.
    2. If I am registering the ActiveXViewer.cab deliverables manually in the client machine report is launching fine, but we cannot do the same for the entire client machine having Windows 7 Enterprise Operating System.

    Hi Ludek Uher,
    Thank you very much for the information provided by you.  But still the same error (The Crystal Report Viewer is unable to create its resource objects) occurs after changing the IE8 Compatibility mode.
    Are there any other settings that can be tried for this issue?
    Thank You.

  • How to change the package name of View or Window

    Hi all,
    i have created the Webdynpro Application.i have some Views and Windows in the WebDynpro Peoject.i want to change the package Names of Views.is it possible???
    thanks in advance
    regards
    Naidu

    Hi Naidu
        Though you rename the package name, the view in that package refers to the old package and hence that view can be used in other views by including the old package name only. Renaming doesn't have significance that you expect. You can create a new package and views in it and copy the implementation of views from the old package to the views in the new package.

  • Firefox won't open PDF files after I removed older version of PDF-xChange Viewer and installed the lastest version of PDF-xChange Viewer. MS Explorer which I am now force to use works OK. I have checked the Applications window in Tools/Options and it l

    Firefox no longer opens PDF files. Explorer works OK. I have checked the Applications window in the Tools/Options and it says I am using PDF-xChange viewer....It just does not do anything. I get the message in the Download Error window which says...."could not be saved, because you cannot change the contents of that folder. Is the same error which I get when I attempt to open a PDF file on a webpage using the Firefox browser....Explorer works OK so I am now forced to Explorer to read PDF files via a browser.
    == This happened ==
    Every time Firefox opened
    == After removing a old copy of PDF-xChange Viewer and updating to the last version

    The error message suggests that the file (pdf) that you're trying to download cannot be saved in the folder Firefox tries to save it in.
    This can be due to several things - it could be a non-existing folder (could be a problem with the updated application), the hard drive could be too full to store the file (less likely if you can generally surf the net without error messages) or it could contain an error.
    To complicate things a little further, it seems to me that you have (at least) 3 different PDF-handling plugins in Firefox from different programs:
    PDF-XChange Viewer Netscape Gecko Plugin
    Adobe PDF Plug-In For Firefox and Netscape "9.3.2"
    Zeon PDF Plugin For Mozilla
    This shouldn't matter too much, thou, as it will most likely simply use either the latest installed or the first one it finds when looking up associations for files of type 'pdf'.
    First, in Tools > Options... > tab General > section File download, select "Save files in" and Browse your way to a (non-writeprotected!) folder on a drive where you're certain there is enough free space - like the Desktop folder to make the files end up on your Windows desktop.
    Second, under Applications as you mention yourself, find all document types related to PDF files, and set these to one of the programs. Check the entire list to be sure there isn't one hiding under one of the other programs' document types (Adobe Acrobat document, PDF X-Change and Zeon).
    Restart Firefox, and try opening a PDF again.
    If it fails once more, try changing the documents again to one of the other programs, like "Use Adobe Acrobat (in Firefox)".
    If it STILL fails, change it to simply "Save file". Then you can simply browse your way to the download folder with Windows Explorer, and doubleclick the PDF file to see which program actually handles PDF files as default on the machine, and if it works properly.
    If Firefox flatly refuses to save the PDF files in a folder which you're certain both exist and has space for the file, some (probably security related) program is most likely interfering with Firefox, preventing it in storing PDF files on the system.

  • Creating a master-detail relation between a view and a table

    Hi all,
    I have a problem with creating a master-detail relation between a database-view with lots of customer data and a small table with per customer a list of entities of our companies who may work for that customer.
    Somehow I seem to be unable to create a relation between these two. I can't find where I can make a foreign key using Toplink to implement the relationship. And neither can I get a Viewlink object doing the job using ADF Business Components.
    Somebody any suggestions on this problems?
    Regards,
    Birgit

    There is a key relationship between two fields which form the primary key in the main table of the view and two fields in the second table.
    I created a viewlink manually, but I still couldn't get the data correct i.e. a form with one record of a customer from the main view and a small table with all entities of our company who can make performances for that customer.
    I tried to find a manual or a how-to on this topic but I didn't find anything helpfull yet.
    Regards,
    Birgit
    After a couple more tries, I got the master-detail working. With all the fiddling I am not sure what caused the problem but I think the finally action was checking which fields of the view were marked as primary keys.
    Now everthing is up and running.

  • Essential event viewer bugs with "Forwarded Events" log in Windows Server 2008 R2 and Windows 7

    To my general experience, Windows event viewer is one of the most problematic, faulty management tools in the case of extensive use of its more sophisticated capabilities. The sole description as well as reproduction of some entangled failures would require
    remarkable effort.
    With the "Forwarded Events" log however, the situation becomes particularly worse in that even simple functionality fails and workarounds are difficult to find. That’s what I’ll describe here in order to share my experience with interested users.
    For precision: I’ve extensively used event viewer on a German Windows Server 2008 R2 SP1 (Windows SBS 2011 Standard SP1). The bugs I found on that system, I could reproduce on a German Windows 7 Professional 64-Bit SP1, too.
    Problem 1: Failure of even simple event filtering
    To reproduce this problem, execute these steps on a test machine with any of the two OS mentioned above:
    (i) To prepare log contents, do either of the following:
    (a) populate some events to your local "Forwarded Events" log (most simply by subscribing events from other logs of the same machine; stop subscription if you have collected some events)
    Or
    (b) copy a non-empty log file "ForwardedEvents.evtx" from another machine (with any of the two OS mentioned above) to your test machine and open the file in event viewer.
    (ii) Navigate to your "Forwarded Events" test log and open the filtering dialog. In the "Includes/Excludes Event IDs" field, type: 1-9000. Click OK.
    (iii) Look at the results pane: Surprise, 0 Events! Do you really have no event IDs between 1 and 9000 in your test log?
    (iv) Another example, if you have forwarded security events in your test log: Clear filter, if any previous filter is in place. Open the filtering dialog. In "Keywords" sub-dialog, choose "Audit Success". Click OK.
    (v) Look at the results pane: Surprise, 0 Events! Do you really have no successful security monitoring events in your test log?
    I’ll finish here. If you have a rich variety of events in your test log available, let your imagination run wild to test around. Finally include some simple manually created or modified XPath filters on the XML tab of the filtering dialog. I promise, you’ll
    find a lot of additional strange results.
    Problem 2: Cannot save manually selected events to .evtx file
    Navigate to your "Forwarded Events" test log. In the results pane, select one or more events by highlighting them by mouse clicks. In context menu, choose "Save selected events". In the "save as" dialog, choose file type *.evtx
    and save your file. Open the newly created file in event viewer. Result: Surprise, no events inside the new file!
    Have more fun with forwarded events
    Helmut

    Did you mean that right click Forwarded Event and select "Filter Current Log..."? Since I can filter correct event vai the "Filter Current Log..." in my Lab environment.
    Hi Justin,
    yes, I mean "Filter Current Log ... " (in my German systems: "Aktuelles Protokoll filtern ... ").
    What do you mean with "my Lab environment" exactly?
    In the meantime, I performed additional tests. I copied the "ForwardedEvents.evtx" test file from Server 2008 R2 resp. Windows 7 to
    (i) German Windows 8 Pro 64-Bit RTM
    (ii) German Windows 8.1 Pro 64-Bit, up-to-date
    in order to view and filter the file there.
    Results: Same event viewer problem on Windows 8 RTM, but correct behavior on Windows 8.1!
    Best regards, Helmut

  • Raid- Understanding "Hot Spare" and Windows reinstall - Final Steps

    Hello all,
    If you follow couple of my other recent threads here you will see I have a warning of a failing drive in my 4 tb raid (4 x 1TB raid set.)
    Also for an unrelated reason I am also needing to reinstall Windows 7.  (and of course my Adobe Master collection CS5)
    I ordered a 5th drive to serve as "Hot Spare" and it will be arriving sometime today from Amazon.
    I want to make sure I do the above "final steps" properly, in the correct order.
    I am basing my "final steps" based on Harm's advice on another thread:
    >>>
    You can never be too safe with data, but if you follow the hot-spare,  extend raid set and rebuild sequence, it is not necessary. Your data  will be reconsructed automatically. That is the reason you use a  raid3/5.
    Your log file is a definite show of a serious  disk problem. Replace it, create a hot-spare, extend your raid set and  rebuild (it should be done automatically) and you are ready to roll
    >>>>
    (As a precaution I have done a backup of my raid, to an external drive)
    So once my new hard drive arrives today from Amazon, I will, in the following order:
    1)  Replace failing hard drive.  (Do I need to power down the computer to remove the failing hard drive and replace it with the hot spare?  Or can I leave the computer powered on so that the raid software can continue its CONSISTANCY CHECK while II do all of the steps to rebuild the raid  --- see note at bottom of this post...)
    2)  Create hot-spare
    3)  Use the Raid controller software (Areca) to EXTEND HOT SPARE
    4)  Rebuild raid (it should be done automatically)
    THEN, after I confirm that the raid is working okay, I will
    5)  Reinstall Windows 7.
    THe below step is what I am not entirely clear on:
    6)  I assume since the raid has already been rebuilt {before I did the windows 7 reinstall) I can do a very straightforward "reconnect" to the already working raid.  In other words, I would reinstall the Areca raid software (using the Areca cd) and identify the raid and windows 7 will recognize the 4 tb raid as my raid drive.
    I am tracking the delivery of my new hard drive and it is at least 5 or 6 hours away from arriving from Amazon.
    ****  CONSISTANCY NOTE: I the meantime I am having the Areca web based controller software do a CONSISTANCY check of the raid.
    It is half way through the check and has found 144 errors so far.   The consistancy check is rather vague about what it is doing.  But can I assume that it is finding the errors and will automatically fix them.
    Or do I have to do something to fix the errors once the consistancy check is finished (This is one reason why I would like to avoid powering down during the rebuilding of the raid.)  Or will creating the hot spare, etc interrupt the consistancy check, meaning I must finish the consistancy check completley before rebuilding the raid.
    Or should I abort the consistancy check and do that after I reinstall windows.  (If possible I would like to do that so I can get on with the editing of my current project!!)
    WHEW!

    6.6.5 Check Volume Set
    To check a volume set from a RAID set:
    (1). Click on the “Check Volume Set” link.
    (2). Click on the volume set from the list that you wish to check.
    Tick on “Confirm The Operation” and click on the “Submit” button.
    Use this option to verify the correctness of the redundant data in
    a volume set. For example, in a system with dedicated parity, volume
    set check means computing the parity of the data disk drives
    and comparing the results to the contents of the dedicated parity
    disk drive. The checking percentage can also be viewed by clicking
    on “RAID Set Hierarchy” in the main menu.
    Directly from the Areca 1600 series Manual. I would let that finish.

  • Access 2010 on 64 Bit Windows 7 Access "Not Responding" when changing from forms view to design view and back

    I am running
    Windows 7 64 bit
    Access 2010 32 bit
    Developing an application with a split FE BE with both files local but continue to have the message "Not Responding" when switching from forms view to design view and back as well as if I try to connect to a subform or object on the sub form.

    I have seen this behavior when the form's RecordSource is a complex query such as a crosstab or a query with several nested queries. To test if this is your case, remove the RecordSource and see if the form starts acting normal again.
    Then again, if the form has several subforms they might be slowing up the loading time.

  • Incompatibility between JDK 1.4 and Windows XP Fax and Picture Viewer

    I have noticed an incompatibility between JPG files that are output from Windows XP Fax and Picture Viewer and read in by JDK 1.4 (or 1.4.1). In particular, when an image is transfered from a digital camera to a Windows XP machine, then rotated and saved in the Windows XP Fax and Picture Viewer, the resulting image file appears with corrupted colors when read and saved by the ImageIO class in JDK 1.4.
    Here is my code:
         import java.awt.image.BufferedImage;
         import javax.imageio.ImageIO;
         BufferedImage buffImg = ImageIO.read (new File ("in.jpg"));
         ImageIO.write (buffImg, "jpg", new File ("out.jpg"));
    I have also output the file with graphics format PNG and seen similar apparent corruption of colors.
    This is an image that was loaded onto Windows XP from a digital camera then rotated 90 degrees and saved with the Windows XP Fax and Picture Viewer:
    http://www.adigitalsolution.net/pics/verticalOrig.jpg
    Here is the same image read and written by JDK 1.4 ImageIO.read() and ImageIO.write():
    http://www.adigitalsolution.net/pics/verticalJavaOut.jpg
    Note that the colors appear corrupted in the above image.
    This is an image copied directly from a Sony Cybershot DSC - P71 digital camera:
    http://www.adigitalsolution.net/pics/horizontalOrig.jpg
    Here is the same image read and written by JDK 1.4 ImageIO.read() and ImageIO.write():
    http://www.adigitalsolution.net/pics/horizontalJavaOut.jpg
    It appears fine (brilliant tropical colors).
    Note that both images contain the "EXIF" header, which is the JPEG-like format used by many digital cameras. Some may say that the JDK 1.4 spec does not support EXIF, but the image not touched by Windows XP was read successfully. And other image editing programs read in both successfully, such as PaintshopPro and the Mozilla 1.0 web browser. But there is a specific incompatibility with JDK 1.4.
    I have reproduced this problem on Windows NT 4 and Red Hat Linux 7.3 using an image file that was saved on Windows XP.
    Here is a warning from Nikon about the behavior of Windows XP Fax and Picture Viewer:
    http://www.dpreview.com/news/0112/01121402nikonxpwarnings.asp
    Does anybody know a workaround?

    This is scary and explains why some of my Exif headers are trashed.
    I would guess the problem has something to do with XP not writing the file back out 100% true to the JPEG spec.
    Really annoying that they do this. They think they can just hack up and change standards that are not their own. Take their FTP client in Windows XP. Talk about a broken client.
    My suggestion is to dis-associate jpegs with XP's image and fax viewer. Instead associate them with Mozilla.

  • In IPhoto 11 I have made an album and rearrange the photos in the order I require them. When export the album to allow me to burn them to disk to be viewed in Windows they do not maintain the same order. What am I doing wrong?

    In IPhoto 11 I have made an album and rearrange the photosin the order I require them. When export the album to allow me to burn them todisk to be viewed in Windows they do not maintain the same order. What am I doingwrong?

    When you sort the Album in iphoto are you sorting manually? Or by date of the photos?
    When you sort in the Finder how are are you sorting?
    Here's one way to do what you're trying to do:
    Create your Album and sort the pics as you want them. Then Photos Menu: Batch Change -> Set Title to Text "John's Birthday", for instance, and tick the box to append a number to each Photo. Now your photos are titled 'John's Birthday 001, John's Birthday 002 ... etc'
    Then File -> Export and in the Export dialogue set the Filename to "Use Title"
    Sort on Filename in the Finder and you end up with a folder full of images in the same order as the Album in iPhoto.
