WD Portal Eventing - Reload wd-iView depending on second wd-iView

Hi all,
I have got the task to implement the following:
Two different wd-iViewsv(a and b) are embedded in the portal. If the iView a is loaded (reloaded), the iView b should be reloaded too.
Does anybody know, how to solve this problem?
Thank you in advance!
Best regards, Patrick.

Portal eventing between bsp and VC

Hi everybody
I need to use portal eventing to have a bsp and a VC iview communicate.
The bsp iview should be displayed within the VC iview as html view, raise a portal event with some sort of parameters inside, and then be dynamically hidden by the main iview.
I have often read about VC and bsp exchanging signals when belonging to the same page, but will this work even with bsp iview within VC iview? Has anyone ever achieved this?
thanks
Vincenzo

Hello Vincenzo,
It won't work, since the html view is implemented as an iframe on top of the model. If you want to use portal eventing, you should have the iViews inside a portal page which acts as a container and you also have the entire portal framework working for you.

Webdynpro proxy page and portal event

Hello there,
is it possible to capture the event from employee search iview into my custom webdynpro ABAP iview?
Since it occurs to me that when a portal page is developed as a "Default page template" I am able to capture the event whenever manager clicks on any employee in the list. But when i create a page with "Web dynpro proxy page" template, I cannot subscribe to the event.
We are trying to use employee search ivew and general data iview provided by SAP plus a custom WDA iview. But when I do a default page template, I am able to caputre the event but general data iview does not show any data...and when I use the proxy page template...I get data in general data iview but I am not able to capture the event....and my custom WDA iview does not show anything...
Employee search iview (previously known as team viewer) and general data iview are standard SAP iviews.
any ideas...
appreciate the help!
Thanks....
J.

Hi Srivastava,
The scenario is like this....
page lay out:
Team viewer iview here----provided by SAP
General data iview here-----provided by SAP
my WDA iview here-----custom iview
if the page template is default template....I get data in my WDA iview for selected employee in the team viewer...but I go not get any data in General data iview
if the page template is web dynpro proxy page...i do not get any data in my WDA iview...but i get data in general data iview...
after debugging this thing...i found that for webdynpro proxy page...the portal event is not getting caught in my WDA iview...
how to subscribe to a portal event if the iview is embedded in a page which is using web dynpro proxy page template...
Just want to share this...that portal eventing is working fine...if the my iview is embedded in a page which is using default page template...
any ideas????
anyone???
Thanks...

CRM portal eventing

Hi all,
We are using portal eventing to manage idle sessions
we have seen CRM bussiness package for portal don't raise any event
do you know if it's any way to suscribe this events or any configuration to launch it?

Portal eventing between Java WD iview to ABAP WD iview?

HI Experts ,
I have requirement on which,
The manager can select an employee from the EE Search iView (Object and Data Provider). All other iViews react on the selection and display data of the selected employee. Technically the personnel number is transferred from the search iView to the other iViews on the portal page, also to the related activity iView. This mechanism is called Eventing. The applications, started via the related activity iView, are launched with the personnel number as parameter. With other words the application, e.g. Manage Objects on Loan, can be directly started for the employee selected from the EE Search iView.
The Employee Information page is based on WD Java whereas the Objects on Loan application described in this specification is based on WD ABAP...........Due to different technologies used how to do the Pernr number transfer between these iviews?
If anybody have done this let me know the steps
Thanks in Advance,
Dharani

Hi Dharani,
You can use portal events to enable iViews running on the same page to communicate with each other. You just have to find out which event is fired by the WD Java iView and then you will have to register and handle the event in your WD ABAP application : http://help.sap.com/saphelp_nw70ehp1/helpdata/en/f6/7d6f4151dc5758e10000000a1550b0/frameset.htm
You can use HttpFox (firefox plug-in) to find the details of the fired event (name, namespace...) by looking at the eventQueue parameter in the HTTP POST request.

Pierre

Portal Eventing: communication betn BSP - WD iView

Hi All,
i am doing portal eventing between WD Abap iView and BSP iView with the help of blog <a href="/people/thomas.jung3/blog/2005/12/15/portal-eventing-a-solution-for-global-peace-and-harmony:///people/thomas.jung3/blog/2005/12/15/portal-eventing-a-solution-for-global-peace-and-harmony.
i have created page which has both iViews.
but i am not able to trigger the event from BSP to WD.
please suggest me some direction regarding this.
Regards,
Chandra

Hi,
the domain is the first part in your URL, for example www.sdn.sap.com.
In your case it will probably the hostname of your computer.
The reason for this is security. The portal eventing is build in Javascript and in Javascript it is not allowed to access other frames that are not in the same domain.

Portal Eventing between WDP Java iView & non-WDP iView

Dear Experts,
I have 1 Web DynPro Java iView and 1 non-Web DynPro (using JSPDynPage and JSP) iView, both attached to a page. When Web DynPro Java iView fire a portal raise event, the portal iView did not execute the javascript function tied to the event subscribed.
Here is the code snippet which reside in the Web DynPro Java iView that is used to fire the event
String param = "test";
WPortalEventing.fire("urn:com.company.Test1", "TestEvent", param);
This the code snippet that is in the jsp page
function notifyTest(param){
// code to print param value is here
EPCM.subscribeEvent("urn:com.company.Test1", "TestEvent", notifyTest);
Note:
1. When Web DynPro Java iView fire the portal event the entire page is refreshed, including the non-WDP iView.
2. When EPCM is replaced with window.top.EPCM, the page is refreshed, it is totally hanged with progress bar.
Can anyone help to solve this problem?
Edited by: CloudSOmnislash on Apr 8, 2009 6:06 PM

Kumar, Rui,
I have all my code inside a web dynpro component. All that I have in dynpro to work with (or that's what I know so far) is a WDPortalEventing object that I can use to access the fire, subscribeEvent and unsubscribeEvent methods. I still haven't found a way to get to the actual EPCM object that the Portal runtime gives you through javascript. And even if I get there, how am I supposed to write javascript in my dynpro code and later pass the value stored in the client data bag to the web dynpro context ?
Simon,
I had tried a small app yesterday and it didn't work when the iViews were not assigned to the same page. I will see if I can change my code anymore and get it working. I will make fresh posts to this thread as and when I find anything that works. In the mean time, if you have webdynpro iViews that talk to each other across pages, do let me know how you are doing it!
Thanks for your replies...

Can a SAP Gui iView raise a portal event?

Hi Folks,
Can anyone tell me if a SAP Gui iView can raise a Portal Event via the EPCF (or equivalent)? I seem to remember reading a blog on this way back but my sleep deprived mind could be deceiving me?
Thanks a lot,
Dan

I don't think so. I think there was a hack a while ago about making it a target by wrapping webgui inside another frame, but not as an event raiser.

Portal Eventing JSP TreeView

I am trying to refactor a piece of code that was originally designed using HTMLB to create a tree view role menu that invokes an event in another iView.
My question is, can portal eventing be done with traditional JavaScript as opposed to using HTMLB? We are not using WebDynPro for this project.
I would like to use a jsp treeview to re-engineer the existing htmlb tree structure, but wanted to get some feedback on the options...thanks

Hi Ryan,
> whether or not the eventing
> has to be done on the server side
The eventing between iViews is done by EPCF, and this is, as said, a pure JS framework. Often it might be senseful for the iView which gets "informed" by some other iView about some event with some event data, to use this data and to refresh itself. This depends on the concrete use case.
Having this said, it is obviously totally independent if you usue EPCF from some portal HTMLB-JSP, a "pure" JSP without HTMLB or a BSP - all of these things end up in HTML with the possibility to include JS - the EPCF calls.
See http://help.sap.com/saphelp_nw04/helpdata/en/82/04b340be3dff5fe10000000a155106/frameset.htm for further details.
> Can all of this be done without post backs
> to the server,
As said before, the eventing through EPCF works on client side, but in many cases it makes sense to refresh some iView with some data sent by the event.
Imagine a List-Details iView combination. The user has one iView with a list of products and another iView with the details of one product. By choosing one product in the list iView, this iView could raise an event, which is subscribed by the details iView, for example passing some product-ID. Now it would make sense to refresh the details iView with the ID given. The alternative would be to load all details data and only to show up the chosen details and to switch on the event. Two disadvantages: It's much harder to code and you may have a very long transmission/network time for the inital call of this iView.
> without using htmlb using JSP not BSP
See above, it's independent from the HTML-Layer.
> can you store a result set in a client side object,
> like a cookie, and if so, how?
For sure, somehow you can (at least some representation). But here I'm unsure again, in which direction this question aims, if this is really helpful.
Hope it helps

Portal eventing in WD ABAP

Hello ,
We have an requirment to pass values from one WD ABAP application iView to another in the Enterprise portal.Is there any configuration that needs be done in WD ABAP or is there any setting in EP that we need to do ??
Rahul

Rahul,
Though most of this stuff is of web dynpro for java. You can just replace java Code with ABAP.
You need to use eventing functionality.In the SAP Enterprise Portal, different application types in specific iViews can be arranged on one page. To communicate between the different iView types the portal provides the Enterprise Portal Client Framework (EPCF), also known as client-side eventing. This document describes how Web Dynpro applications can use EPCF.
http://help.sap.com/saphelp_nw04/helpdata/en/24/243ca46e1c334f8a6f8b0792656bc7/content.htm
The following code shows the signature of the subscribe method:
WDPortalEventing.subscribe(java.lang.String nameSpace, java.lang.String event, IWDAction action);
for example
WDPortalEventing.subscribe (urn:com.sap.tc.webdynpro.test.portal,
    TestEvent,
    wdThis.wdGetTestEventAction());
You have to define the events name and its namespace. The combination of these two names must be unique.
The third parameter is the Web Dynpro action, which should be mapped to the portal event. The action event handler is called if the Web Dynpro application receives the specified portal event on the client side. The mapping between a portal event and a Web Dynpro action is done automatically and it is completely transparent for the Web Dynpro application developer.
You can reuse a Web Dynpro action for several portal events. If you want to receive the portal events data you have to define the following parameters for your Web Dynpro action:
·        dataObject
The dataObject parameter contains the portal event parameter.
·        nameSpace
The namespace parameter contains the portal events namespace.
·        name
The name parameter contains the portal events name.
It is useful to add the nameSpace and nameparameters to the Web Dynpro action if the action is reused for several portal events because you can use this information to differentiate between the portal events.
Note: In the current version a portal event subscription is valid for a Web Dynpro view. Therefore you should add the required Java coding, for example in the wdDoInit() method of the generated view class. If you navigate between different views, you have to subscribe to every view for the portal event required.
Unsubscribe from a portal event
Unsubscribing from a portal event is very similar to subscribing. The following code shows the signature of the unsubscribemethod:
WDPortalEventing.unsubscribe(java.lang.String nameSpace, java.lang.String event, IWDAction action);
for example
WDPortalEventing.unsubscribe (urn:com.sap.tc.webdynpro.test.portal,
    TestEvent,
    wdThis.wdGetTestEventAction());
Note: You must unsubscribe every Web Dynpro view, because subscription and unsubscription is valid only for the current view.
Raise a portal event
The following example shows how to raise a portal event. The signature is:
WDPortalEventing.fire(java.lang.String nameSpace, java.lang.String event, java.lang.String parameter);
for example
WDPortalEventing.fire (urn:com.sap.tc.webdynpro.test.portal,
     TestEvent,
    AParameter);
You can fire a portal event anywhere in your Web Dynpro application. The event is sent to the client with the next response. You can also raise more than one portal event in a request-response cycle. Typically, you will fire a portal event in a Web Dynpro action event handler (for example, as a response to pressing a button).
The following step-by-step example shows how to carry out portal eventing within two simple Web Dynpro example applications.
Example Description
The user can enter an arbitrary string in an input field. If the user presses the pushbutton Click here in the sender view, the input string will be displayed in a TextView UI element of the listener application.
Prerequisites
You have built two Web Dynpro applications. How to build Web Dynpro applications is described in Creating a Simple Web Dynpro Application. In each application you have created a Web Component with a view that uses the portal eventing.
You can find the detailed procedure describing how to insert UI elements into a view in Creating a Simple Web Dynpro Application.
Further information about the integration of a Web Dynpro application into the SAP Enterprise Portal can you find under Running a Web Dynpro Application in SAP Enterprise Portal.
Procedure
Creating the Web Dynpro applications
       1.      Create the Web Dypro project. Call it webdynproexample_portal_eventing.
       2.      Create two Web Dynpro components. Call them:
                            a.      EventSenderComponent
                            b.      EventListenerComponent
       3.      Create two Web Dynpro applications. Call them:
                            a.      EventSenderApplication
                            b.      EventListenerApplication
Creating the necessary views:
Create the layout of the EventSenderView in the EventSenderComponent as follows:
Create the context structure of the EventingSender View:
The context value attribute Name must be of type String.
Create an action Show
Define the data binding of corresponding UI element properties:
The appropriate properties of the UI elements must be bound to the context that contains and displays the data.
       4.      Define a text, for instance, Enter a text: for the label UI element (ID: NameLabel) using the property text.
       5.      Bind the property value of the input field (ID: NameInputField) to the context attribute Name.
       6.      Bind onAction of the button (ID:ShowButton) to the corresponding action Show.
Implementation of the view controller
       7.      If you create an action declaratively within the SAP NetWeaver Developer Studio, the Web Dynpro framework automatically generates an onAction method in the controllers implementation. The generated method enables you to write code to fetch the input string and to fire the portal event. The fire method of WDPortalEventing passes the data and the name of the event that should be handled by the second application as parameters. The following code shows the implementation of onActionShow method:
public void onActionShow(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionShow(ServerEvent)
   String name = wdContext.currentContextElement().getName();
    WDPortalEventing.fire("urn:com.sap.tc.webdynpro.example.portaleventing",
                       "Show",
                       name);
    //@@end
Create the layout of the EventListenerView in the EventListenerComponent as follows:
Create the context structure of the EventingListenerView:
The context attribute Name must be of type String.
Create an action, for example, ReactPortalEventing which should be mapped to the portal event.
       8.      Create an action ReactPortalEventing.
       9.      Add the parameter dataObject. It should have the type java.lang.String.
Define the data binding of the corresponding UI element properties:
The corresponding properties of the UI elements must be bound to the context that contains and displays the data.
10.      Define a text for the NameLabel for example, The entry is displayed in a TextView UI element:
   11.      Bind the property text of the TextView UI element (ID: TextViewShow) to the context attribute Name.
Implementation of the views controller
   12.      You have to subscribe to the event within the wdDoInit method. You have to define the namespaceof the event and the name of the event, for example Show. The third parameter is the Web Dynpro action, which should be mapped to the portal event.
   13.      You have to implement the action (ReactPortalEventing) that passes the dataObjectand fills the context with data. The following code shows the implementation of the wdDoInit and the reactPortalEventing methods:
public void wdDoInit()
    //@@begin wdDoInit()
    WDPortalEventing.subscribe("urn:com.sap.tc.webdynpro.example.portaleventing", "Show",
    wdThis.wdGetReactPortalEventingAction() );
    //@@end
public void onActionReactPortalEventing(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String dataObject )
    //@@begin onActionReactPortalEventing(ServerEvent)
    wdContext.currentContextElement().setName(dataObject);
    //@@end
Deploying the Web Dynpro Application
Before you can call the Web Dynpro application, you have to build the Web Dynpro project and deploy the application on the J2EE Engine.
Simple Testing of the Portal Eventing and Calling the Web Application
   14.      Create two iViews in the newly-created example folder as described in Running a Web Dynpro Application in SAP Enterprise Portal.
   15.      Create a page and add the two iViews to the newly-created page.
To preview the Web Dynpro applications, choose the button Preview in the Portal Content Studio.
   16.      Enter your input and choose button Click here.
Result
A page preview will demonstrate portal eventing.

Embedded WD and portal eventing

Hi,
In MSS-> Equipment I have the standard Employee Search wd component and a custom web dynpro component that displays obejcts on loan(pa0040) embedded in an iView. The PERNR is being successfully passed to the custom application when the user clicks on the employee name. Is there any way I can clear the objects displayed if a user clicks on anything else in the standard wd component. For example, if they click on a company name in the Organisation structure?

Probably the whole thing works based on Portal events. I assume they have no other means to know what is being selected. Best way forward is subscribe in custom component to other events such as Organisation. If there are no events fired in that cases then you may have problem here. You can try enhance the existing component and fire a clear event. Subscribe this event in your custom component.
Handle this clear event in your custom component and invalidate the node for loan.

Portal eventing

Hi all,
Can someone give me the code to create a portal event from PCUI ? I'm trying to combine Visual composer iview with a PCUI Iview. Sender is the PCUI Iview and receiver is the VC Iview.I just need to be able to pass a field value from PCUI to vc.I need to know how to code (what class/interface) I need to use to create a portal event from PCUI ?
I've followed quite a few weblogs but I did not find something that creates a portal event from PCUI. Appreciate your help!!
Thank you
Sreesanth.

Sree,
I am not sure what do you mean by portal event from PCUI.is it Client side or server side event ???
You cant write your own client side (JavaScript) events in PCUI, Client side scripting is done by FW.
May be you need to do a modification in FW java script files to have your client side event.
You can have server side events from PCUI

Java Portal Event not received correctly by ABAP Webdynpro

We have a page that contains 2 iviews.
iView 1 contains the MSS Employee Search that raises portal event:
Namespace: "urn:com.sap.mss.employeesearch"
Name: "selection_changed"
The second iview contains an ABAP Webdynpro program that subscribes to the Portal event.
The issue is that the event in the ABAP webdynpro is not being triggered. It does get triggered if we first fire the event from the Java program, unsubscribe the event in the ABAP program them subscribe to the event in the ABAP program. The event gets triggered at this time and the parameter can be retrieved.
If the event is fired a second time, nothing happens in the ABAP program.
The abap program works fine when another abap program triggers the same portal event.
Also, the portal event is being picked up correctly by other SAP delivered JAVA programs. I just cannot get a custom ABAP Webdynpro program to work...
Any ideas, comments?
Glenn

Hi Glenn,
Are you using https? Is your j2ee stack and abap stack in the same domain? In the past I have found that https can cause issues in the event communication between different applications.
Cheers,
Dion
