AJAX Top-level navigation (TLN)

Hi,
11 months ago SAP released a whitepaper about new UI technologies:
<a href="http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/b7259e66-0e01-0010-8ea4-c72990c41d7c">Using the SAP NetWeaver Enterprise Portal and NetWeaver Business Client - Technical and Business Advantages</a>
Has anyone heard anything more about the following bits:
"L-frame containing the portal navigation tree can be cached in the browser"
"browser will receive a “face-lift” to modern, AJAX-based UI and behavior"
It also stated:
"A detailed roadmap and timeline will be published by SAP in the near future."
but I haven't seen anything - has anybody else?
Has anybody seen a roadmap / timeline? Dates or SPS level etc.?
Regards
Jim

  • Enable Hoover Menu in Ajax Top-Level-Navigation

    Hi all,
    currently we´re upgrading from 7.0. SPS18 to EHP2 SP6. We want to use the AJAX framework page. We also want to have a hoover menu in the Top-Level-Navigation.
    I´m aware of the tutorial in the SDN (http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/6066b302-09c8-2a10-a894-eb9fef30df85?QuickLink=index&overridelayout=true), but I also want to use the widget tab.
    Anybody around who did a hoover menu in an AJAX framework page?
    Thx and Rgds,

  • Problem with WPC and Top Level Navigation

    Hi all...
    I have one problem. I'm using WPC and my role name is shown in Top Level Navigation (TLN).
    For example:
    Role name: Test
    navigation nodes: company, About Us, Finnancial, News...
    "Test" role is shown on TLN first level and the first level of navigation node is shown on TLN second level.
    How can I remove the role name from TLN first level? I already changed the entry point parameter to "No" however this case the navigation node disappear from TLN.
    tks

    Praveen,
    How can I set the "No" Entry Point parameter to my navigation nodes??
    In my role configuration I only changed the External Connector and Entry Point Parameters.
    Where can I set up the No entry point parameter for my navigation nodes?

  • Top Level Navigation Problem

    Hi guys,
    recently, I ran into something really strange. The Top Level Navigation (TLN) became faulty. If the user clicks on certain entries in First Level Navigation or Second Level Navigation the content area is not loaded properly. The content area stays empty as well as the detailed navigation iView (no navigation entries listed). Furthermore, the TLN does not get updated.
    The weird thing is it only affects a few users and the set of affected navigation tabs is different for every user. The problem affects standard tabs (System Administration, Content Administration, etc.) as well as custom tabs. The set of affected users and the set of affected tabs seems to be arbitrary chosen.
    A new log entry is written every time the problem occurs. Find an example below:

    While searching SDN I found a SAP Note that might be interesting. SAP Note 982496 contains the description of a similar problem with almost the same error message. However, this SAP Note describes a problem of NW 2004 SPS 17. A problem that should be solved in newer releases. We patched our system last time (NW2004s SPS 09) a few month ago. We never had any similar problems until last week when the above described problems started.
    Unfortunately, the problem starts to escalate. More and more users and more and more navigation tabs are affected.
    Does anyone of you have any experience with this kind of problems? Please suggest how to troubleshoot and solve this very annoying problem. Of course, I am going to reward helpful answers.
    Best regards,
    Martin

    Hi Harini,
    thanks for your suggestions.
    1) Clearing the browser cache did not help at all.
    2) We disabled the navigation cache a long time ago. That means navigation is not cached.
    3) We are going to restart the portal server today. I keep you updated.
    Best regards,
    Martin

  • Make top-level navigation smaller in size

    Hi all,
    the default top-level navigation in the AJAX framework uses quite a big piece of the browser window (almost 70 px). This space could be used better especially when integrating reports.
    So my question is how to reduce the height of the top level navigation (first level only) from around 70px to maybe 40-50? Can this be done in the portal theme editor? Unfortunately there is no preview available yet when editing AJAX specific settings. Or do we need to change the coding of the framwork page?
    I think it would be pretty messy to change all the pictures and fonts that are used in the top-level navigation.
    Thanks for any suggestions or even the "it's not possible" answer.
    Regards,
    Fabian

    Hi Fabian.
    But shouldn't it already be possible to change this?
    At least you can built your own theme on a base of default one and then directly modify css and image files. However, I do not recommend this solution as far as AFP still in active development.
    Will the mechanism to change the theme be enhanced in EhP2 an do we know when EhP2 will be available?
    Yes, full support for customization is planned in Ehp2. According to an addendum to SAP's Release Strategy for Large Enterprises, status July 2009, which you can find at [Service Marketplace|http://service.sap.com/releasestrategy], EHP2 for NetWeaver 7.0 is rescheduled to June 2010.
    Best regards,
    Aliaksandr Zhukau
    P.S.: Why not just use the "Full Screen" button? It hides TLN.

  • Top Level Navigation - Design bar borders

    SAP EP 6.0 SP9 on NW04
    We're using the top level navigation iview (TLN) out-of-the box and have configured the look and feel of TLN using the Theme Editor so that it follows the customer's corporate identity.
    However, we cannot remove the two white vertical borders around the design bar in top level navigation or change the color to the same color as the top level navigation. It is only possible for us to change the background color of the design bar but not the color of the design bar border. The marketing department thinks this is a huge issue, which must be fixed.
    We're almost certain that the problem cannot be solved by configuring the Theme Editor.
    Does anybody know whether it is easy to modify the code or css files to change the white borders of the design bar? Any idea of what is the best approach?
    Best regards
    Peter
    Can

    Hi,
    I have similar problem but there is no "Display of Design Bar Container" option in the Top Level Navigation section of the Theme editor.

  • Top Level Navigation jumps to wrong workset

    Hi,
    In our portal (SP15), rather than loading the first page/iview of each workset in the top level navigation, we wanted a starter page that said something like 'click a menu item to continue'. To achieve this, I created the relevant URL iview and added it (delta-link) to each workset that appeared in the TLN. I then changed the properties of the iview so that it was Invisible in the Navigation AND Default Entry for Folder. So now when you click on a TLN node, the iview appears but doesn't show in the menu.
    However, this has created some strange behaviour. Once a node on the TLN has been selected that points to proper page or iview (i.e. one that appears in the navigation), if you then click on any workset on the second level (first level ones are ok), the TLN "jumps" back to the node which has the page/iview - but still shows the starter page iview. This means that users can't access any workset on the second level, except the first one to be displayed (i.e. when you have several nested worksets in a workset).
    Can anyone explain why this is happening? The problem only occurs when the starter iview is both Invisible in the Navigation AND Default Entry for the Folder. Is this expected behaviour (and if so, why?) or is it a bug? Is there another way to achieve what we want?
    Many thanks
    Jane

    If I do that, the iview does not appear because I already have an Entry Point above that level (i.e. the Workset). Entry Point as Yes only sets the initial navigation node, it doesn't force an iview to appear. (or at least this is what my testing has shown).
    We may have to rethink how we can do this - does anyone know of a way to stop the first iview/page loading in every TLN node, and instead just showing the portal background?
    Many thanks
    Jane

  • Customized Top Level Navigation iView

    Hello to all
    We are using a customized TLN iview. Its source code was modified to admit different URLs, and do the filtering depending of the default framework page which is using the TNL iview,
    I mean, the TLN would be copied inside a proyect folder on the Portal Content, where would be a DFPage that contains a copy of TNL iview, and this copy would have a different roleFilter attribute.
    Then, the TLN was modified again in order to merge roles that had the same name.
    Those changes doesn't seem really important, they have just declared some vars, and each of them added one code line. The first one extended the first part of an IF condition, and the second one extended it with another condition, using OR.
    The problem is that after the modifications, our TLN doesn't highlight correctly the first node when accessing or refreshing the Portal, instead of it shows a default start page that doesn't belong to any of our roles
    The TLN iview has a procedure named PrintNavNodes, which is called on the event OnClick (I assume), and when we accessrefresh the page too.
    The iview works well when clicking its buttons, it's just the first time it is used when the wrong page is shown, that's the problem we need to correct.
    This procedure (PrintNavNodes) lodges the code changes. The only var modified is String prefix, so maybe anyone could tell me a default value to it, o a way to catch that mistake in order to show another page when the default page is to appear.
    Also, I would appreciate if anyone knows about an API, andor a How to... manual, or any kind of documentation about this subject.
    We have no possibility of reject the changes, so we need to find an alternative solution. Here is the code...

  • Hide Top level navigation if user assigned only one role

    Hi,
    I would like to hide the top level navigation if user assigned with only one role.
    I can create role based rule to show desktop using Master rule collection, but is it possible by doing to with role count.
    If user has multiple roles show desktop1 else show desktop2

    not sure if this possible ,you may check feasibility of creating  a application which checks user role count and if role count is = 1 load the Portal url (URL alais) which had TLN iview invisible in the same window else do nothing and load the portal with the desktop which has tln.
    Put the application in framewrk page which has TLN visible.
    create a URL alias and create a desktop -framework page which dont have TLN ,assign this desktop to this URL alias in rule collection set its priority before user conditions check in rule collection so that it has high priority before user or group check in rule collection.
    you can create a poc in sandbox and check if it wiorks?

  • How to start Top-Level Navigation on Level two?

    Hi,
    does anyone known a trick how i can start the top-level navigation at Level two?
    I make an own frameworkpage and try to set it in the iview properties, but there is not an property for this. it is only for the detailed-navigation iView there.
    For what:
    I need this, because i would open an pop-up with an other portal window. I link to the popup with navigation-target=... In this pop-up should only be the content of one role. This folder i have set to "invisible in the navigation area". So the User always see him in a popup. when i start at the default Top-navigation level 1, the user see all the other navigation folders.
    Best regards,
    Patrick

    Hi Patrick,
    up to SPS13, this needs some hands on on different parts of the TLN. What I've done this spring was showing all top-level nav targets within a select box in the masthead and then, after having selected one of these entries, the TLN shows just the content of this top level entry. So this is more or less the same. As said, some work to do.
    As of SPS14, with the new navigation taglib, I expect this to be much less work; anyhow, I didn't convert the results into SPS14, so I cannot say if this is really as easy as I expect.
    Hope it helps

  • Creating a dropdown for Roles in Top Level Navigation

    Hi,
    I am trying to customize the com.sap.portal.navigation.toplevel.par file.
    Can anybody please help me to create a dropdown for various roles in the portal,if the user clicks on the first role in the Top Level Navigation ,he should see a dropdown list with worksets of the role.
    Any help would be really appreciated
    Thanks
    Art Tech.

    Hello Art Tech,
    I hope I understand you right. You want to change the appearance of the custom built TLN according to the currently chosen portal theme, just like the standard TLN would change its appearance.
    Well, if so, then there are two ways:
    1) The HTML and styles/classes of your custom built TLN are still more or less the same as in the standard or you can at least reuse most of the standard HTML output/structure, then applying a new theme would also affect your custom TLN.
    2) You have your own HTML output for the TLN, not relying on anything from the standard TLN, and you most probably work with a custom stylesheet file (e.g. "tln.css"). What you have to do then is to provide a set of TLN stylesheet files for each portal theme you want to support and include it accordingly by retrieving the current theme's name via the ILafService (Look & Feel Service). Or you rely on only one CSS file, then have as many "blocks" of styles (marked with a preceding class selector like in e.g. ".themeNameA ul li a " and ".themeNameB ul li a ") as you have themes, and put a bracket around the TLN-output with class="currentThemeName". For this last approach I give you the sample code (assuming you want to support the themes "SAP Standard", "SAP Tradeshow" and "SAP Chrome"):
    The TLN code: tln.jsp
    &gt;<%@ taglib uri="NavigationTagLibrary" prefix="nav" %>
    &gt;<%@ page import = "com.sapportals.portal.prt.service.laf.*" %>
    &gt;<%@ page import = "com.sapportals.portal.prt.runtime.PortalRuntime" %>
    &gt;<%
    &gt;// include the TLN stylesheet
    &gt;response.include(componentRequest, componentRequest.getResource("css", "css/tln.css"));
    &gt;
    &gt;// retrieve the current theme's technical name
    &gt;ILAFService iLAFService = (ILAFService)PortalRuntime.getRuntimeResources().getService(ILAFService.KEY);
    &gt;String currentTheme = iLAFService.getCurrentTheme(componentRequest).getThemeName();
    &gt;%>
    &gt;
    &gt;&lt;div class="<%=currentTheme%>"&gt;
    &gt;  &lt;ul&gt;
    &gt;  <nav:iterateInitialNavNodes>
    &gt;    &lt;li&gt;<nav:navNodeAnchor navigationMethod="byURL" />
    &gt;    <!-- second level ? -->
    &gt;    &lt;/li&gt;
    &gt;  </nav:iterateInitialNavNodes>
    &gt;  &lt;/ul&gt;
    &gt;&lt;/div&gt;
    The stylesheet: tln.css
    &gt;.sap_standard ul li {background-color:#FFCCCC}
    &gt;.sap_standard ul li a
    &gt;
    &gt;.sap_tradeshow ul li {background-color:#CCCCFF}
    &gt;.sap_tradeshow ul li a
    &gt;
    &gt;.sap_chrome ul li {background-color:#CCCCCC}
    &gt;.sap_chrome ul li a
    I hope this solves your problems.

  • Display a custom message on click of a Top Level Navigation Object

    Hi Experts,
    when the user clicks on the top level navigation entry link(for any application), I would like a custom message to be displayed to the end-users which would be maintained in a text file in a KM folder.
    Currently, on click of the top level navigation link a  workset map is displayed. But now I would like to read the text file and display the message (if any) maintained in the text file.
    The message (if any) should be rendered before the workset map is displayed, or be rendered as an additional element on the same page as the workset map perhaps as an additional iView .
    It is essential that the message content should not be cached by the Portal (in other words, the deactivation of the system message should not require a cache flush to become visible to the user).
    The goal is to warn the users before they they access the applications of the workset map.
    Can someone please guide me on this???
    Regards,
    Anurag

    Hi,
    See some info regarding Portal Eventing:
    http://help.sap.com/saphelp_nwce72/helpdata/en/a5/8d1e72c20f4db2b9f577b47c1a47da/content.htm
    In the link above you can see that it's possible to raise an event and subscribe to it.
    Each time you navigate in the portal, the portal raises the UpdateTLN event so all you need it to subscribe to it in an iview that is located on the same page.
    Since the masthead iview is in the same window (above the TLN - see the following link) you can put your javascript function in it.

  • Display Icon/Image instead of Role name in top level navigation

    Hi,
    I want to display a image / icon instead of role name for a particular role. Can you please tell me how to achieve this ?
    Thanks,
    VP

    Hi,
    the thread is just for the background image (for all elements).
    if you want to display icons instead of role names, you have to create your custom top level navigation using the
    navigation taglib from SAP. There are lots of examples. make a blog search for Mr "Kannengiesser" from SAP.
    In case you are using already an EHPx in your EP 7.0 the AJAX framework might have this feature.

  • Show/Hide tabs in top level navigation of a role based on assigned services

    Hi,
    I have an interesting requirement. I have created an overview page in abap web dynpro which has links to various services.
    Based on the r3 roles assigned to the user, we need to show/hide the services in the overview page and top level navigation.
    I can show/hide the views in the overview page but the links on top level navigation are created in the portal frontend by creating worksets, iviews, etc.
    Is there a way I can show or hide these worksets which are defined in the role on top level navigation?
    In a nutshell, can i update the visible/invisible property of a java workset from a call in abap web dynpro?
    Regards,
    Sumeet

    What i meant was that you can do a custom TLN like this

    Seems to me java/jsp is more appropriate than doing it via WDA.
    ANother way that you might look into this is Application integrator which again java programming effort needed.
