Ajax Framework Page

Is there a tutorial or article on how to create or customize your own Ajax Framework page on the portal for the SAP Netweaver CE 7.2 version?
Vijay

Hi,
i think this is quite helpful tutorial on how to create own custom Ajax-based framework.
http://www.sdn.sap.com/irj/sdn/index?rid=/library/uuid/b0adc900-edb2-2d10-6482-bdf4870eb35c
Hope this helps.
Best regards,

Ajax Framework Page - Customized and Modified

Dear All,
I am trying to Customize and Modify the default ajax framework page. So with the help of the [SDN Document |http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70bfe58d-1ed9-2d10-42b6-821d62777d6f?QuickLink=index&overridelayout=true&50599009721255] I tried to implement the same.
We have SAP NW Enterprise Portal 7.3 and NWDS 7.3 SP05.
I created the portal Application Project and portal component and added all the needed css, script, html and images.
Below is the code of my portal component:
package com.sap.itelo.framework.page;
import com.sapportals.portal.prt.component.*;
import com.sapportals.portal.prt.resource.IResource;
public class ITelOFramework extends AbstractPortalComponent
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
         IResource navigationCSS = request.getResource(IResource.CSS, "css/style.css");
         response.include(request, navigationCSS);
         IResource menuCSS = request.getResource(IResource.CSS, "css/menu.css");
         response.include(request, menuCSS);
         IResource navTreeSource =
         request.getResource(IResource.STATIC_PAGE,"html/framework.html");
         response.include(request,navTreeSource);
         IResource navigationJs =
         request.getResource(IResource.SCRIPT,"scripts/navigation.js");
         response.include(request, navigationJs);
I deployed the application and created Framework Page Iview based on the deployed application. When I previewed the page, I noticed the navigation Script page is not loaded. That means, I didn't get detailed navigation on the framework page.
Please tell me where I went wrong and how to resolve this error.

Hi Eben

Information About AJAX Framework Page

Hi,
We recently implemented one portal with EHP1. We find ajax framework page in the pcd.
I already go through some of the documents available in SDN.
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00b99527-da5b-2b10-e4b9-81fb9317f28b]
Even i search help.sap.com release note for EHP1. But didnot found anything regarding this frame work page.
Please tell us, whether we can use this in produciton environment? Can we customize this one? For example i need to use a masthead iview which is on default framework(not ajax) in this new (ajax) framework.

Modification of Ajax Framework Page Layout.

Hi,
I am trying to modify the layout of Ajax Framework Page by importing the war file of com.sap.portal.navigation.afp.layout.
I have the below errors even though I added all the needed jar files .
Can not find the tag library descriptor for "prt:taglib:com.sap.portal.reserved.layout.TagLibLayout"
The method getServletRequest() from the type IPortalComponentRequest refers to the missing type HttpServletRequest
javax.servlet.jsp.PageContext cannot be resolved to a type
epPageVariables cannot be resolved
How to resolve this?
Regards,
Eben Joyson.

Hi,
I upgraded the support pack of SAP NW EP 7.3 form SP05 tp SP07.
Then tried to modify the layout of Ajax Framework Page by importing the war file of com.sap.portal.navigation.afp.layout. Now I am not facing that issue.
Hope it was a bug with NWDS.

Ajax framework : how to remove the Trex search field ?

Hi community,
I am trying to remove the TRex search field in an ajax framework. As for the "normal" framework I make not visible the tool page, even in the headerless framework, but it is still displaying...
Has someone ever face this problem ?
Thanks a lot.

Hi Fabien
I am not sure if i got your question currectly
In general on the Ajax Framework page there is the masthead iview
On the masthead iview there is a property "Enable Search" that allows you to enable and disable the search box in the page.
Please try to use it
There is now search box of the framewrok in headerless window
the search box is probably part of the application.

Problem with Absolute Navigation (External Window) and Light Framework Page

Hi All,
We are using Light Framework page for the portal devolopment. We have an application including two webdynpro iviews where absolute navigation is used to traverse from first iview to second iview (When user clicks a button on first iview). We are showing the second iview in external window (SHOW_EXTERNAL). When ever i clicks the button to traverse to second iview, i am getting an exception.
When we are showing it in same window (SHOW_INPLACE), it is working fine. But the iview is appeared in half of the page with scrollbars. It is working fine with default framework page (with both options SHOW_INPLACE and SHOW_EXTERNAL) and dispalyed in original size as mentioned in iview properties.
Could you please suggest us whether there is any work around for this.
Thanks,
Sudheer

Hi Kathiresan
I couldn't see the address bar of the window (In which second iview is getting displayed). But i can observe no parameters that i passed from first iview is visible in the view source of the second iview (When SHOW_EXTERNAL is used in absolute navigation). I could see all the parameters in the view source (when SHOW_INPLACE is used for absolute navigation). But i am using the same url for both the options (for SHOW_INPLACE and SHOW_EXTERNAL).
I doubt about the url being passed when SHOW_EXTERNAL option is used. But when we checked in debug, The correct url is being triggered (Atleast from first iview). Is there any way that could display the second window with address bar. What is making difference between SHOW_INPLACE and SHOW_EXTERNAL with absolute navigation and light framework page.
Could someone please suggest.
Thanks,
Sudheer.

Opening an ADF page from an OA framework page

Hello,
We have an OA framework page (a custom app) deployed in Oracle 9i Application server. We intend to develop some ADF pages which will be deployed in a separate Oracle 10g AS. I would like to know if it is possible to open an ADF page from an OA page and the basic interoperability between them. If someone can throw some light on the feasibility of this approach, it would really be helpful. Are there any material available on this?
Please let me know your thoughts on this. Thanks in advance
Raja

You way want to ask this on the OA Forum as well.
Because you are running the apps on different servers the interoperability can only be through the db layer. I'm not aware of a solution where the apps are running in the same context, meaning you can't have an transaction spanning both apps.
To open a page of an other app is simply done by putting a link in one app which points to the second app.

PDF file cannot be viewed from OA Framework page.

Hi all,
I have developed an OA Framework page which shall present an XMLP report in pdf within the browser.
When I click on my menu item which opens the oa page, the Open file.. diaglog appears. When I open or save the file (and thereafter opening if) the following error appears: _Acrobat could not open [filename] because it is either not a supported file type or because the file has been damaged._
I can open the file if I go to the server and copies the output file to my own machine.
The error that i'm describing is happening on the server and NOT in my development environment. I cannot get it to work at all on my own machine.

Ajax Framework Navigation Detection

Hi
We are currently adapting a component to work with every framework on the portal.
This component has to detect navigation(and respective node) and then do a amount of actions on pre-defined services with Java Code.
The problem is as far as i can understand the Ajax framework uses client Side Events to navigate(using LAPSI javascript) and the navigation_helper_service .getCurrentSelectedNode does not work.
How can i track the last navigation made in this Framework?
Thanks

Hi,
This issue is an application issue and not a OBN issue as the application has already rendered.
I have found this note that may be helpful to you:

Add to favourites disabled when using light framework page

Hi,
When using the light framework page our "add to favourites" link is disabled. If we instead use the normal framework page add to favourites in the dropdown menu works. Does anyone have an idea why this could be?
Regards
Mattias

Hi,
The reason why I decide to use Light Framework, itu2019s because Iu2019m creating an EFP, and Iu2019m using the WPC to publish the content (articles, news, and link list), using the standard Web Forms.
The problem is, after adding to a WPC Page something so simple like an article (using the Web Form Article), no Portal iView, HTMLB or other stuff included, the preview of the WPC Page using the Default Framework Page is ok, but when using the Light Framework Page, the text in the article doesnu2019t have the correct font-family. It looks like there are some styles missing in the Light Framework Page, that WPC content is expecting.
Thanks and Regards,
