How to change web-dynpro layout in preview ?

hi there,
i have a big problem:
i want to hide fields from a web-dynpro-application. this is possible when i go to content admin, then open the iview with right click and PREVIEW. then with right mouse click + CTRL i get to the editor to hide field, change fields, etc...........
so far so good, BUT: i have a dynpro, which is displayed after approving absences in ESS.
i don't get to this dynpro as it is not possible for me to get to this dynpro, as i am (as admin) not a person who can approve such absences.
how can i change this dynpro, when it does not work with preview ?
reg, Martin

Hi SAPTECHED / Evandro,
You've TWO options to handle the default messages by WD framework:
1# OnAction Without Validation:
If you are using any onAction() event for your wdj form validation.. then open the Action method in Edit mode > Check the Without Validation check-box property > Save it. This would avoid calling the default validation messages that comes from Web Dynpro framework.
2# Dictionary Messages Property file:
Otherwise modify the messages_en.properties file part of SapDictionaryTypesRuntime.jar located in the server-side (this is usually part of com.sap.dictionary.runtime_2.0.0 plug-in at client-side [WDJ installed machine] system). And make sure you've a ORIGINAL copy of this property file.
Hope this should resolve your query!
Thanks,
MS

  • Modifying / Moving objects in Web Dynpro Layout

    Hi.
    Can someone tell me if it is possible to edit buttons or other objects from Web Dynpro layout? If it is possible, how can I do this?
    When I say edit, I mean move button/object to certain location or make size bigger.
    I know I can do this in Adobe form layout, but I am hoping I can keep adobe form separately from buttons, so off-line Adobe form will not have buttons.
    Thanks in advance for your help.
    John

    Hi John,
    There is no property by which the size of a button can be changed. Although the text can be varied by using property "Design" of the text elements.
    As far as position is concerned, The button can be placed anywhere according to user requirement. The simplest way of doing that is creating a toolbar and creating right aligned or left aligned buttons. or by just using the properties of the layout you are using.
    Check the [Layout documentation|http://help.sap.com/saphelp_erp2005/helpdata/en/47/af8841349e1909e10000000a155106/frameset.htm] for more details

  • Web Dynpro Layout

    I am trying to create an application for calling Adobe interactive form in Web Dynpro ABAP, however my problem is that I am not able to see the Web Dynpro Layout in the VIEW in transaction SE80, the message appears on like the one on internet explorer 'This page cannot be dispalyed'. I checked the settings, but I am not able to understand what is missing in the system. Please help me on this issue.

    Incidentely while the layout designer area is nice, you can do 100% of your work without it.  You can use the Tree view of the UI elements on the right side of the screen to add/delete/move items just fine.  Sure you lose out on the WYSIWYG preview, but you can still work.  So while it is good that you fix your problem (and it should be quite fixable with the suggestions given) you don't actually have to wait until you get it fixed to work.

  • Web Dynpro Layout cannot be displayed

    Hi Guys,
    I am a beginner using Web Dynpro technic and I would like to know if there is a configuration need to be made to Internet Explorer or in SE80 to display the layout correctly?
    For example, I created a text element in a view and in the Layout Tab the Web Browser always tells me that "This program cannot display the webpage"
    Is there a special parameter to set up to enable Internet Explorer to display the Web Dynpro Layout? I cannot really find documentation on the subject actually.
    Thank you in advance for your answers.
    Sylvain

    I post this every once in a while, but everyone should be aware that having to make an entry in your hosts file is NOT normal. I know a lot of people post that as solution, but if you are having to make an entry in hosts file to resolve the URL of your ABAP AS then something is wrong with your network configuration.  Your basis administrators should work with your network administrators to get a proper DNS entry setup for your ABAP system. Surely you don't expect that all end users accessing you WDA applications will have manual entries in their hosts file.

    Hello Dharani
    All required function modules can be found in function group SLVC (assuming that you are using OO-based ALV or, at least, fm REUSE_ALV_GRID_DISPLAY_LVC):
    LVC_VARIANT_DEFAULT_GET (Read default display variant (description only, w/o field catalog))
    LVC_VARIANT_EXISTENCE_CHECK
    LVC_VARIANT_F4 (Display variant selection dialog box)

  • Web Dynpro-layout preview-Error-IE cannot display-service in SICF activated

    Hello,
    By starting a view in web dynpro framework, i have the error in tab layout "page cannot be displayed" from IE.
    Before i make the change in the DNS and system32/../etc, the layout was displayed, but the web dynpro application cannot be started.
    Now after those configurations and activation of services in SICF, i can start the web application only with firefox and not internet exploer, and, that internet explorer is preconfigured for the layout preview, i recieve all times the eror "cannot display" when i start a view in the layout tab.
    1. How can i change settings so that view can be displayed in layout after i actived the (hope the suitables i.e. view designer) services in SICF - Default_host...
    2. Is it possible to change IE to firefox as main browser for layout tab.
    Note: For virtual domain i
    1. add dns "domain.com" in the DNS
    2. add in system32/etc/host file to "127.0.0.1 localhost",    "10.10.0.10 sysserv.domain.com"
    3. and trough tr. rz10 in the instance profil input the icm/.... ....domain.com

    and just send error the message: "THIS PROGRAM CANNOT DISPLAY THE WEBPAGE"

  • Submit Button In Web Dynpro Layout not working.

    Hi All,
             I have integrated an adobe form in my web dynpro application.According to my requirement the view of screen should change when the user clicks on submit button.So I have given the submit button as one of the UI element in my WD object along with the form.But when I click on the submit button the functionality doesnot work.
    The same submit button works when there is no adobe form integrated in my WD application.
    Please let me know what needs tyo be done so make that submit button work.
    Thanks and Regards,
    Sarang

    Sarang,
    Lets go step-by-step.
    1. Create two views in your applications lets say the names are View1 and View2.
    2. Goto Diagram View of the Window in under Windows node in your Web Dynpro Explorer in NWDS.
    3. Create Inbound and Outbound plugs for View1 namely inbView1 and outView1
    4. Repeat the same for View2. So names will be inbView2 and outView2.
    5. Create a navigational link between the Vies by creating a link from outView1 plug to inView2 plug.
    6. Goto Layout tab for the View1. This is where you have embedded the Interactive form element.
    7. Set the displayType property to native.
    8. Under Events there will be onSubmit method, craete a new method called navigateToView2 and click Go. This will take you where you can implement your logic.
    9. Fire the outbound plug of View1. See following code snippet:-
    public void onActiong navigateToView2(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
        //@@begin onActiongotoView2(ServerEvent)
        wdThis.wdFirePlugOutView1();
        //@@end
    10. Edit the Interactive form, it should open Adove LiveCycle Designer.
    11. Drag-drop Submit button from WD Native library ontot the form.
    11. Don't modify anything and check if you see below code snippet in the Editor.
    // DO NOT MODIFY THE CODE BEYOND THIS POINT - 705.20051114114126.253659.250577 - SubmitToSAP.xfo
                          ContainerFoundation_JS.SendMessageToContainer(event.target, "submit", "", "", "", "");
                          // END OF DO NOT MODIFY
    12. Now whenever you click submit button on the form, what it does is that it makes call to WD framework and the onSubmit action handler is called where you have written the code to navigate to View2.

  • How to use Web Dynpro Java isChanged and isChangedByClient

    Hello,
    I have read thorugh a lot of documentation, threads, ... --> but the picture is not geting clearer fro me.
    We have Web Dynpro Java Application (on Netweaver 7.0 SP12) running in Enterprise Portal. We need to tell the portal work protect mode, that we have unsaved changes (how to do this is clear).
    I am struggling with figuring out, that my Web Dynpro Context has unsaved changes. I found the two change-indicators isChanged() and isChangedByClient(), which already confuses me a little bit.
    Anyway, this is what I have figured out so far:
    I am calling wdContext.currentContextElement().isChangedByClient() to figure out changes and when a Save operation has been completed sucessfully, I call wdContext.currentContextElement().node().getContext().resetChangedByClient(). This works for some of the changes made by the user.
    I then tried calling wdContext.nodeABC().getElementAt(i).isChanged() for all nodes of my Web Dynpro Context, but this results in detecting changes before the user ha done any interaction.
    Implementing an own change tracking (i.e. by adding a changed-Attribute to each context node) does not seem a viable option for me.
    So these are my questions:
    - Does anyone now a working pattern relying on those chnage indicators ?
    - Does anyone now how to reset the isChanged indicator (or when it is resetted by the framework) ?
    Any help appreciated.
    Thank you,
    Stefan
