Detailed Tree Navigation

Friends,
I have to develop a custom detailed tree navigation wich will start at the first level.
In our new design the Top Level Navigation doesn't exists.
The initial nodes will start collapsed.
I think I'll have to create a new jsp but I'm new at portal customization.
Can anyone have some example or tutorial that can help me in this task ?
Thanks for help,
Ramatís

Hi Ramatis,
Here is some of the suggestion I can provide for you:
1) Develop Navigation tree via JSP - using NavigationTagLibrary Taglibs - Please refer to the following blogs by Sven Kannengiesser, the provided example demostrate the usage of the NavigationTagLibrary and the sucker fish drop down.
EFP: Working with the new Taglibs - Part 3
2) Develop Navigation tree via AbstractPortalComponent - You can find code example in NWDS's help content on how to builde a Sitemap. This sample shows how to use portal services to populate navigation node. You can blend in your HTML, CSS and JS on top of this sample to create your detailed navigation.
From the NWDS menu bar -> Help Contents ->SAP NetWeaver Developer Studio Documentation ->Portal Development Manual->Go and Create->Creating a Site Map
3) Develop Navigation tree via Webdynpro - Using Portal Services - com.sapportals.portal.navigation.INavigationService to get portal navigation node and bind these node to webdynpro Tree UI.

CQ.BrowseDialog tree navigation doesn't work in IE = 10

Hi,
I've got a problem with CQ.BrowseDialog widget. I'm using it through CQ.form.PathField and surprisingly the tree navigation inside doesn't appear to work in Microsoft Internet Explorer 10 (but it does work in IE 8 & 9 and any other browser). The dialog pop-ups normally when I click on search icon, and all buttons (Close, OK, Cancel) react properly. But when I click on filesystem elements, they don't expand, colapse or highlight. Sadly, JS console doesn't throw any errors.
My CQ version is 5.4.0.20110218. Can you help me with fixing the issue, or at least give some idea how to debug this widget? Many thanks.
Regards,
Michal.

I managed to find and install the package (I think that's the right one) from:
http://dev.day.com/packageshare/packages/public/day/cq540/hotfix/cq-5.4.0-hotfix-35198.htm l
...but it didn't help. The tree navigation in BrowseDialog still doesn't work in IE 10 and there are no JS errors in my console. Description of the package I installed says about some fixes for IE 9, but not for newer versions.
IE got me used to some errors, but rather in older versions. Here we have an opposite situation: a widget won't work in IE 10. Can I do anything more now, for example debug CQ widgets JavaScript? Any advice welcome.
Regards,
Michal.

Customize detail level navigation

Hi,
I want to create my own detail level navigation(dln) iview. I need to have the same functionality of the standard dln iview with minor changes.
So my question is : Is there any par file provided by sap so that I can extend or simply reuse it.
Next question is :
From which jar files I can get the following classes.
com.sapportals.common.PPLogger;
com.sapportals.common.TracingConsts;
com.sapportals.portal.useragent.IUserAgent;
com.sapportals.portal.useragent.IUserAgentService;
Thank you very much for the time.
Best Regards,
Shiva

Hi Shiva,
EP provides bak files for many of its UI, like masterhead,TLN etc. Like that it also provides the bak file for detailed navigation area.The par file is
com.sap.portal.navigation.detailedtree.par.bak
U can get this par file from server System Admin>>Support>>Portal Runtime>>Browse deployment>>WEB-INF>>Deployment>>pcd.
Import this par file into ur NWDS and edit it accordingly.
Hope this helps

Content Item Typ: Tree Navigation Link

Hi,
I was told that there is one Tree Navigation Link in the content item types. However I can't see it in the page group configuration.
I am using oracle 9iAS 9.0.2, portal 9.0.2??, JPDK v2 July one.
By the way, how can I know the portal version? I didn't do the installation. Everything comes with the oracle 9iAS installation. I did upgrade the JPDK.

There is currently no item type that does a tree-style navigation.
A new tree-style navigation portlet is coming soon from the Portal Integration Solutions team.
There are also a couple of navigation portlets available from the Knowledge Exchange. I've tried this one and it works great.
There are also some great navigation and search extensions available from Oracle Consulting.
To find the Portal version number, look on the Builder Page, Admin tab, General Settings. Scroll to the bottom of the page.
Regards,
Jerry

PDF Extract with CR XI SP2 can't contain the tree navigation.

During the training, I attend at BO on Crystal Report XI SP2, when I made a PDF export, I was allowed to choose if I want the Tree Navigation or not in the PDF file.
Currently my report ".rpt" are set-up with a tree navigation, but there is no the "Checkbox" on the Export Window for PDF.
Are they any set-up required on Crystal Report XI SP2
Thanks in advance
Alex

Hi
By defat, you should get the Check box for "Create bookmarks from group tree". In case you are not getting that, you can check the following:
1. Click on Start -> Control Panel -> Add/Remove Programs -> Select Crystal Reports XI R2 and click on Change.
2. You would get the CR set up dialog box. Click on Add/Remove.
3.Exapand the Export Support ->Click on the drop down of Acrobat PDF Format -> Click on Entire feature will be installed on local hard drive.
4.Click on Next -> Next -> Finish.
Restart Crystal Reports.
Hope it helps!!

JSF/MyFaces tree navigation

Hi All,
i am writing a web-app that renders a tree style menu on the left handside of the page, and on the right hand side will be rendered the page that the clicked tree node is mapped to. What is the best component with which to implement the latter part? The tree2 from MyFaces works absolutely fine for the tree navigation panel, but I don't know what to use for the second half of the page.
Any help would be greatlly appreciated.
Angus

it should be action="admin", but not onClick="admin"

Regarding the detailed level navigation theme change

Dear Experts,
I am using Light Detailed Level Navigation iview .And in the theme if I make change for the backgrond color of the theme related to DLN its not reflecting for the entire tray .For some part of the dln the changed color is reflecting(where and all links appears) in the other parts its showing the default color.
Can someone help me in this regard.
Thanks,
Regards,
Rudradev

Hi Sunil,
Do you really want to place the image at the right side of the TLN - or at the header (which is different)?
In the first case, there is a mixture of JavaScript and JSPs (containing JS) which build up the TLN, and this is quite complicated to understand (at least too complicate for a SDN thread). You would have to work through the code and try to modify it carefully.
In the secondd case, you are touching the wrong PAR, but you would know the right one (as you opened a different thread about such a modification).
Alternatively, you could try to use the light framework page, using the navigation tag library. This way, it is more easy to design your own UI, including the nav functionality.
Hope it helps

Group tree navigation script error - 64 bit server

Hi,
We have crystal reports embedded into our WPF application. The WPF application resides on 64-bit server with windows server 2008 OS. When trying to run a report and use the group tree navigation we are getting a script error. This is happening only when we run the report in 64-bit server. We tested the same report on a 32-bit server and everything works fine. Attached is the screen shot of the same.

Always, always quote the exact version of CR used and the version of .NET. No sense even guessing without that info...

Detailed Level Navigation missing post NW 7.31 portal SP12 upgrade

Hi,
We are on NW 7.31 portal . We have recently upgraded portal from SP 9 to SP12. Post upgrade the the detailed level navigation panel is missing . I have checked the role and workset setting and its absolutely fine. Any idea what might be the issue? It was visible before upgrade.
Regards,
Navya

Hi Navya,
When you click on a link for an SCA file you see on the right side a yellow icon, that's the dependency calculation tool, it will automatically tell you the dependend components.
In this case:
Notice you have a download button on the right side for each SCA.
Hope this helps,

Hi.
I never used tree as navigation but I guess next:
Using goLink to navigate the pages then ADF Lifecycle is executed again and the ADF tree is initialize again to the default status.
You should think how to maintain the current status of the ADF Tree (One size doesn't fit all: Follow up: Programmatic ADF Faces Tree holding state across requests).
I hope this help you.

Does it exist?

cf omentree, for instance, or destroydrop.
If your portlet is suposed to navigate between pages of a group pages, there are shared portlet (NavigationMenu and DHTML menu) downloadable from knowledge exchange.

Detailed Level Navigation Missing

When we have upgraded Portal (NW2004s) from SP13 to SP14 we were not able to see the Detailed level Navigation in Production environment, that was working fine in Development and Test environments; Also the content area was missing because of the upgrade.
Can anyone throw some light on this?

HI,
Please confirm that your Portal framework in production environment contains Innerpage->detail level navigation iview in that. If not then u have to import that from dev server.
Same you can check for the Content Area whether framework contains Content Area iview.

Tree Navigator Component

Does anyone know where I can find some code samples that use a tree navigator component with JSF?
I tried the MyPlaces panelNavigation/commandNavigation tags but could not make it work and couldn't find any good code samples to show me how it is supposed to look.
I also tried the OurPlaces tree/treenode tags and only got it to partially work. Again, I couldn't find sample code that worked for me.
I am using Java Studio Creator so maybe that is part of the problem.

The FTREE builtin package is poorly covered in the Forms 6i online help, and well hidden. You have to search for FTREE, you won't find it otherwise. It does not appear in the help menus. When you do find some mention of it, you have to wander around the related subjects to find the rest of the help that even the Search cannot find.
The Navigator is now a native object type, replacing the old add-on.
It still has its faults and idiosynchrises, but it can be made to work well. To use it with 6i web forms, you need a recent patch set. 6i client/server and 9i are fine.

Tree Navigation and Link - Open iview in Content Area

Hi,
this is maybe trivial, but I can't find anything about it right now:
I created an iview in Java that shows a custom tree in the detailed navigation area.
Now I have an iview ( a BW apps), that should be behind this link on the inner tree level, and, when clicked, should show up on the inner desktop.
What is the java code that needs to be put into the nav iview to do this? How do I identify the URL that is behind the BW apps that I need to call?

You could also let your custom link in the masthead point to a "quicklink" then you do not have pass any url as parameter you just call as it is and you get what you need.
Do not forget to set the "target" property of the link tag to "_top"
Cheers,
Benjamin
