IView errors in Dynamic Navigation area of Page

Hi,
I am developing a Java DynPage iView on EP6.0 SP10 (NW04). The iView functions similarly to the SAP MSS Team Viewer, except that it calls an R/3 Search Help to get a list of employees to display. The iview uses the EPCF framework to generate client side events that are picked up by other iviews on the same page.
Now, the symptoms of my problem: I created a portal page and added the iview to the dynamic navigation area of the page. I have two other iviews that react to the event that is raised by my iview. They are in the general content area of the page. The page is added to my test role as normal. I test the functionality by logging into the portal and accessing the page via the normal portal navigation. Everything works fine, until I leave my session idle for around five (5) minutes. At that point, if I do anything in the iview, I get a runtime error:
"An exception occurred while processing a request for :
  iView : N/A
  Component Name : N/A
iView not found"
If I refresh the page, everything's ok again. This only happens when the iview is in the dynamic navigation area of the page. If it is added to the general content area of the page, the problem does not occur.
It looks like some kind of timeout value, but I'm not sure where to start looking. My HTTP session is still alive at this point, as is my SSO cookie. And, as I said before, I don't get the error if the iview is not in the dynamic navigation area of the page.
Can anyone give me advice on what to do to fix this problem?
Thanks and regards

Hi Frank,
Unfortunately I did not get an answer. I am currently busy with other things so this problem is not receiving a lot of attention right now. If I do get an answer, I will post it here. If you are able to fix it on your side, I would appreciate it if you could let me know too.

  • Portal Runtime Error in Dynamic Navigation Area

    Hello gurus,
    In our production portal all of sudden we are getting a portal runtime error in Dynamic Navigation Area.  Earlier there was a problem with one of the clustered nodes and it was resolved.  I was wondering if this error is in connection with that.  Has anybody faced such problem?  Following is the error we are facing in the dynamic navigation area.

  • Sort of IViews in Dynamic Navigation

    Hello,
    i have added 3 iviews to the dynamic navigation of a page.
    How can i sort these iviews in the navigation-panel? Sort-Priority and Merge-priority are not working for the dynamic navigation. I added I1,I2,I3 to the navigation of the page,but it is displayed I2,I3,I1.
    How can i influence the sort behaviour of iviews in the navigation panel?
    Marco M.

    Hi Marco,
    It is not a nice solution but what you can do is to sort it with the iview id e.g.
    iView1
    iView2
    iView3
    if you change the iView <b>id</b> of iView3 to aiView3 the sort order will look like:
    aiView3
    iView1
    iView2
    Since you do not change the <b>displayname</b> it will still show:
    iView3
    iView1
    iView2
    Hope it helps you
    Best regards

  • Dynamic Navigation opens in new window

    I currently have an KM Navigation iView assigned to Dynamic Navigation of a page.  Clicking on internal links in the Navigation iView opens in a new window.  Is there any way to configure the KM Navigation iView (assigned to Dynamic Navigation) to display in the Portal content area instead of opening in a separate window?

    If you're using Safari, choose Preferences from the Safari menu, click on Tabs, and change the setting.

  • IViews in dynamic navigation take up whole content area

    Hi,
    I'm having a problem using dynamic navigation. I've created two Web Dynpro iViews A and B. I've added B to the dynamic navigation of A and put A into a role. Know when I want to view A, I can see the iViews loading, B in the navigation panel and A on the right of the panel. But once they are loaded, B is shown in the content area, "above" A (effectively hiding it). Once I remove B from the dynamic navigation, A is shown fine.
    Any ideas to solve this?
    thanks,
    Lieven

    Hi Lieven!
    I can only guess, that the WebDynpro integration-IView is designed to run in the content area alone and forces so.
    Did you try to run other (sap provided) WebDynpro iviews from the dynamic navigation?

  • Understanding Dynamic Navigation iview.....

    In MSS, I have the following workset in my role...
    ->Team (workset)
       ---+ Team (webdynpro proxy page)
       ---+ Employee information (folder)
       ---+ Employee Working Time (folder)
       etc....
    The "Team webdynpro proxy page" has an iview ,"Services", assigned in "Dynamic Navigation" but there is nothing particular about that iView itself. However, all folders (and their contents) below the Team webdynpro proxy page appear in the Dynamic Navigation panel (like "Employee information" and "Employee Working Time"). I do not understand the connection between the dynamic navigation iview and how all folders in that workset know to display in that dynamic navigation area. There seems to be no explicit assignment. How does that work?
    edit: a bit more info....the "Services" iview is part of the Common Parts business package and based off the "related services" iview template. Still not sure how it "knows" to display the objects below that page that has it assigned as dynamic nav.

    Did you blog about this solution?  If so could you direct me to the blog?  We need to add numerous links to outside URLs in Related links.  I need to order them somewhat differently than alphabetically.
    Thank you,

  • Dynamic Navigation iView ordering

    Hi,
    We have a problem with ordering iViews in the Dynamic Navigation of pages. We had this issue during SP11 and SAP was upposed to fix this in SP16. We have upgraded to SP16 now. Just want to confirm that this problem is not solved yet (atleast not using the sort priority).
    Also, are there any workarounds to acheive this?

  • WD Java iView & Dynamic Navigation Problem

    Hi,
    I'm trying to use a WebDynpro Java iView in Dynamic Navigation but have the following display problem:
    When I navigate to the page for which I've added the iView to the dynamic navigation, only the WebDynpro iView (from the navigation) is shown. You can see the page in its correct form being loaded but as soon as the navigation iView seems to be loaded/ing it replaces the full lower part of the screen (navigation and content panel).
    If I use a plain URL iView in the dynamic navigation the behaviour is as expected.
    But if I add a WebDynpro iView or even a page containing that iView I get the strange behaviour again.
    I'm running NW04s SP7.
    Any ideas?
    Do I have to set some properties on the WebDynpro iView?
    I've tried a couple of things but none did work so far.
    Thanks & Regards
    Markus

    Hi Henrik,
    Sorry for the late reply but I'm just back from vacation.
    No, I have not found a solution. I decided to go for an integrated application instead (Main WD application that bundles navigation with other applications). That works but of course is not as "nice".
    Have you come across some solution yet?
    Kind Regards

  • GenericCreator: How to add iview as Dynamic Navigation

    Hi All,
    Had anyone used the "Uploading Content and Actions" into the portal via XML file process to add an iview into a page into the Dynamic Navigation portion which will cause the iview to load up on the left panel of the page.
    I am able to do this via the Portal manually, but would like to know how this can be achieve using the .xml and the GenericCreator.

    Hi Mary,
    What I meant by being able to do this manually in the portal, is the process of going into Content Administrator > Portal Content  finding the page that I would like to add the iview into.  Selecting the page, executing a Right-Click > Edit-Dynamic Navigation.  Then finding the iview, Right-Click > Add to Dynamic Navigation.
    This will add the iview into the Dynamic Navigation portion of the selected page.

  • Open portal page via HTML URL out of the "Dynamic Navigation"

    Hi everybody,
    In our portal environment we have a page (page1) in which user can enter date. On another page (page2) in a different navigation node there is a report that shows the data. We want to provide a possibility to navigate directly from page1 to page2.
    Our idea was to have a KM-document iView  in the "dynamic navigation" of page1 with a link to page2.
    that works fine. but page2 is not opened in the whole window but in the dynamic-navigation-frame.
    the link looks the following:
    <A HREF="http://xxxxxxxx.xxx:1235/irj/portal/index.htm?navigationtarget=roles://portal_content/folder/role/workset/page/">
    Its obvious that the link is opened in the same frame because no target property is added to the href.
    I thought about adding a the "target" property to the  href, but I don't know how the Frame is named.
    I have tried this:
    <A HREF="http://xxxxxxxx.xxx:1235/irj/portal/index.htm?navigationtarget=roles://portal_content/folder/role/workset/page/" target="MainFrame">
    but it didn't work.
    Does anybody know how the MainFrame in the portal is named or has any other solution to my problem.
    Regards, Alex
    Edited by: Alexander Paulus on Nov 20, 2008 4:09 PM

    kind of simple
    user target="_top" to have the page displayed in the whole window.

  • Pass parameter from dynamic navigation iView to WebDynpro iView

    Hi All,
    I know there are a lot of threads dealing with passing paramters from EP to WebDynpro using EPCM but actually I didn´t find a solution for my problem.
    I have in the dynamic navigation area of the SAP Portal an iView based on a JSP dynpage. In the corresponding JSP I fire an EPCM-event:
    EPCM.raiseEvent("urn:test.de:wochenb" , "passDataToWebDynpro" , evtData);
    In the content area there is a WebDynpro iView. In this WebDynpro-application I subscribe to the event in the wdDoInit-method of a view:
    WDPortalEventing.subscribe("urn:test.de:wochenb" , "passDataToWebDynpro" ,wdThis.wdGetDataFromJSPDynpageAction());
    and I have an event-handler:
    public void onActionDataFromJSPDynpage(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String dataObject )
        //@@begin onActionDataFromJSPDynpage(ServerEvent)
         IWDMessageManager manager = wdComponentAPI.getMessageManager();
         manager.reportSuccess("EPCM event testing " + dataObject);
      //@@end
    My problem is now that the event is fired correctly by the JSP Dynpage but the event-handler of the WebDynpro is never executed.
    As info: the domain of the J2EE-Server the webdynpro-application is deployed to is identical to the J2EE-Server the portal runs on.
    Can anybody help ?
    Thanks !
    Bernd

    Hi All,
    I found the solution by myself.
    For information: Click in the dynamic navigation fires the event und forces the content afterwards to refresh. During the refresh the WebDynpro subscribes to the event in the wdDoInit-Method. This is to late because the event is fired before the refresh.
    My solution is to use a setTimeout before the event-triggering in the dynamic navigation iView.
    Regards,
    Bernd

  • IView template for navigation Area

    Hi all,
    Did someone knows if there is a template or a framework to create special Iview for the navigation area , like page title bar or Masthead iView.
    Thanks for your help,
    Best Regards
    Badr

    Hi Badr,
        Since u r renaming and making changes, the original files will not be disturbed. U can create iViews from ur new par files and so the original iViews will not be disturbed. I have not tried eventing in those iViews. May be u can try. I think it will work.
    Steps:
    1. Navigate to pcd folder I mentioned before.
    There you can find the reqd par files with .bak extn.
    2. Make a copy of the reqd file and rename it like my.new.masthead.par
    3. Move my.new.masthead.par to a location outside of the <J2EE-Engine_Instance> somewhere to ur local disk.
    4. Extract the files from my.new.masthead.par preserving the directory structure.
    5. Modify files in the extracted PAR file.
    6. Put the modified files back into my.new.masthead.par.
    7. Copy my.new.masthead.par back to pcd folder or deploy the new par file.
    8. Now u can create iViews based on these par files.

    dynamic navigation
    Posted: Aug 29, 2005 3:03 PM        Reply      E-mail this post 
    Hi
    I have an iview from BW that generates links to reports. I associated this iview to a page as a dynamic navigation link.
    When I click on the link, it does not load the content in the portal content area. I tried _self, _top, _parent as the targets in the BW web template.
    How can I get the content loaded in the portal content area? What is the name of the portal content area frame?
    Thanks
    Sriram

    Hi Sriram,
            I confronted with the same issue as yours but then i did the following.......
    Presuming that two iviews are already created i.e.
        1.Navigation Panel iview with links (left)
        2.different iviews associated to the links.
    Now,
         >>Open the other iviews and select Dynamic navigation in the context menu.
         >>Right click on the navigation panel iview having the links and select "Add to Dynamic Navigation"
    In the first iview for the link the code i gave is
    <a href="link2" class="urLnk" onclick="return EPCM.doNavigate('ROLES://portal_content/xyz/Pages/sampleiview')">Link to Project Plan</a>
    No need of the parent,self,.....etc.
    Hope this helps.
