Eventing between three iviews

Hi all,
I implemented three Iviews in a model and tried to define eventing between them in the following manner:
- Output of iView1 is input of iView2
- Output of iView2 is input of iView3
Eventing is functioning well between iView1 and iView2, but it isn't doing between iView2 and iView3.
Does eventing only work between two iViews once a page? Do I need a different EPCM event than "com.sap.visualcomposer:epcm" for the eventing between iView2 and iView3.
Regards,
Elyes

Hi
Did you give the event between iview1 and 2 and iview 2 and 3 different names.

Eventing between multiple IViews

I have multiple Dynpage IViews on one page. I raise and receive events between the IViews. I can alert the databag or eventObject values. The problem is when I try and write to the IView that has subxcribed to the event.
ending IView:
/****** store initial client data   ******/
     EPCM.storeClientData( 'urn:myOwnNameSpace', 'myData', '15' );
     EPCM.storeClientData( 'urn:myOwnNameSpace', 'myData2', '10' )
/******* set the user name based off of the selected index for Request For *******/
function setRequest(){
     var funcName = htmlb_formid+"_getHtmlbElementId";
     func = window[funcName];
     var ddl = eval(func("Request"));
     var selectedIndex = ddl.getIndex();
     var name = ddl.getValue(selectedIndex);
     EPCM.raiseEvent( 'urn:myOwnNameSpace', 'myRequestFor', name );
Receiving IView:
[code]function myRequestHandler( eventObject ) {
    var passedData = eventObject.dataObject;
    var temp=EPCM.loadClientData('urn:myOwnNameSpace', 'myData');
    var funcName = htmlb_formid+"_getHtmlbElementId";
     func = window[funcName];
     var myTime = eval(func("myTime"));
     myTime.setValue(passedData);
EPCM.subscribeEvent( 'urn:myOwnNameSpace', 'myRequestFor', myRequestHandler);code]
The alert has the data passed but the values are not written back to the JAVA htmlb objects.
I did the same thing using JSP DYnpages and it works. I would prefer nto to use the JSP page. Do I have an option

the problem is not missing the document element value. I have it. I can alert it to the browser. The problem is forcing the value back to the JAVA HTMLB form element within the class.
The problem is closed. I have gone the JSP route which is working.

Using events between EP iView and WD iViews

Hello all,
I'm sending an event from EP iView to WD iView.
it is working fine except i can't pass a parameter between them.
Does anyone know how to pass the parameter?
Thanks, Adi.

Hi,
> Is this documented
More or less, see http://media.sdn.sap.com/html/submitted_docs/60_sp2_javadocs/epcf_toolbox/com/sapportals/portal/prt/service/epcftoolbox/package-summary.html
> he can try "parameter1" instead of "dataObject"
> ...
> it basically a EPCF event
That's what I wanted to say, also this script generator cannot generate other JS calls than the JS-API provides. That's why I advise to check the generated code, to get an idea how these "registered parameters" work (if they do).
Hope it helps
Detlev
PS: If it doesn't help, just let the toolbox go and create the JS by yourself. If you really want more than one parameter, encapsualte them into one string like "myfirsparam=123;mysecondparam=456".

Client side event between Java iView and BSP application

Hi,
I am developing a BSP iView which listen to event raised by standard SAP HR TeamViewer iView. The TeamViewer iView raise a event when user click on the employee list.
EPCM.raiseEvent { "urn:com.sap.pct.hcm.orgmanagement:CurrentObject", "objectChanged", concatenatedKey);
My BSP is subscribing to the event and perform the myreceiveEvent function.
EPCM.subscribeEvent
( "urn:com.sap.pct.hcm.orgmanagement:CurrentObject", "objectChanged", myreceiveEvent );
However, my BSP returns an error message saying that EPCM is undefined. I know that I have to included the java script file. I checked with my basis team guy and they said there is not any js file in ICF. Can someone let me know which file I need to include in my BSP code and where is the file locate?
Thanks,
Eric

Hi Eric,
> the ICF where the BSP is stored
> is in the Oracle database
Eric... the place where the JS fragment - within the BSP - appears, is retrieved by some http request. The script=epcfproxy.js forces the browser to send a http request just to the same relative location the original page came from. Doesn't matter if something is within a database...
> Do you know how to locate the
> epcfproxy.js file in the WAS?
I think:
> and the epcfproxy.js file is in the zip file
> that you suggested
you have found it?! Put it to any place on the BSP server you can access, if you can't set it with relative url, use "/some/.../dir/epcfproxy.js" as location.
> If I am only EPCM but not EPCMPROXY,
> do I need to include the epcfproxy.js in my code?
Have a look at epcfproxy.js. It's no magic at all, you have to call top or parent (just look) and do some minor things. For sure, you can live without the proxy file, you have just to put the neede scripts explicitely on your page, that's not that fine, but it works.
Hope it helps

Eventing between iView and nested iView

I try to make an Event between an iView and an nested iView. I followed the instruction on page 164 in the reference guide and tried some other things, but it doesn´t work. I make an output Port on the one side, there i could select the fields to be displayed. But when I compose the Input Port , there are no field to see.
So what make I wrong?

Hello Marcus,
the main thing about the desired eventing seems to be that when you have placed your data service in the nested iview you have to create a signal-in port<b> by pulling a data connection out of the input port of the data service</b> to create the input-port of your nested iView. Only this way, the port is filled with the input data of the data service.
Back in your main iView you can connect the data flow to the newly created port of your nested iView the same way as you connect to a data service. You then should see the input fields of the data service that you placed in the nested iView and be able to assign values to the input fields.
Hope that helps
cheers

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.

Eventing between Web Dynpro iView and regular DynPage iView

I have seen, done eventing between two dynpage iviews and two webdynpro iviewsHowever, and gone through "How to Use the Portal Eventing for Web Dynpro iViews". However, I have been trying to have a webdynpro iview talk to a dynpage iview but they just won't communicate. Is this even possible?
Ok basically I have a portal page in a popup window with no masthead and top level navigation. The page has two iviews - the top one being an iView that points to a webdynpro application on Server A, and the bottom one being a dynpage iview on the Portal Server B.
In the webdynpro iview, the code for when a button is clicked is
public onSomeAction(Event event) {
    WDPortalEventing.fire("urn:myUrn","eventName","value");
In the dynpage iview, the code i have for it is
myServ = (IEpcfToolbox) PortalRuntime.getRuntimeResources().getService(IEpcfToolbox.KEY);
myReceiver = myServ.getClientEventReceiver(request, "urn:myUrn", "eventName");
form.addRawText(myReceiver.getWrappedScript());
try {
    if (!myReceiver.isReceived()) {
        form.addComponent(createMainScreen());
    } else {
     form.addComponent(new TextView("event received!"));
} catch (Exception e) {
    form.addComponent(createErrorScreen());
I tried all the things I could think of but the receiving iView just won't get the event fired.
Can someone confirm that this should work? and correct me where I've done wrong.
Please help. this is very urgent. your help will be greatly appreciated. thanks in advance
PS. My environments are EP 6.0 SP2 and WAS 6.40 SP14

I am no direct access to the boxes so I can't try your suggestion. It really makes sense that eventing won't work if the iViews are on different domains. I know they are in the same domain but different subdomains.
Anyway, good news I got eventing to work with the mentioned set. I found that that the SAP Java EPCFToolbox API had a bug that kept throwing javascript errors when I tried to have the web dynpro iview fire an event and the SAP one subcribed to it.
I got around it but using the EPCF Javascript API instead.
Code:
response.write("<script>");
response.write("EPCM.subscribeEvent('urn:dla.telework', 'createPdf', doSomething);");
response.write("function doSomething() {");
response.write("window.location = self.location + '&eventReceived=true';");
response.write("}");
response.write("</script>");
So basically just output raw text through the response object and it just works.
On a similar topic, since eventing can only pass string parameters back and forth, I'm still looking for a way to pass other more complex Java objects between web dynpro and sap iviews. From what I haven't they don't share the same session object (which I thought they did). So basically I can't just stick stuff in the session and pull it down on the other end. I'm clueless right now. If anybody has some tips, plesae share. Thanks

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...

Communicate between two iviews

Hi everyone, if i create two iviews. And i want to pass a variable from one iview to the other one by triggling an event .
What technology can help me do that? Thx~~

Hi Louis,
Communication between two iviews is accomplished by EPCF concept.

How to transfer parameters between two iViews?

Hi all,
I have two WebDynpro based iViews (StartView and SecondView). when I press the button in the StartView, the EP will navigate to the SecondView. During this process, I want send a parameter value from the StartView to the Second View. In the StartView, I use the follow method to navigator:
WDPortalNavigation.navigateAbsolute(
              "ROLES:portal_content/com.sap.itsamtest/com.sap.secondpage",
                 WDPortalNavigationMode.SHOW_INPLACE,
                 (String) null,
                 (String) null,
                 WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
                 (String) null,
                 (String) null,
                 "value=From Start Page");
In the SecondView, I use the WDWebContextAdapter to get parameter's value.
String Name = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("value");
It works fine. But I found there is a warning message:
The method getRequestParameter(String) from the type IWDWebContextAdapter is deprecated
So is there any other good mechanism to implement the data transfer between two iViews.
Thanks and Best regards
Deyang

Portal eventing between pages

Hi,
I read around that portal eventing can be done only on the same page and not between pages, is this correct? if so, how do we make events between pages after all?
Thanks in advance,
Aviad

Hi Aviad,
Portal eventing takes place between different iviews of the same page only.
To pass between values between different pages, you can store the required value in a Portal Request object or Session object.
Also you can refer to this link,
iView to iView communication with EPCF
This link contains the code to establish connection between pages .Finally obtaining paramaters through request.getParamater().
Hope this helps,
Regards
Uma.
Note: It will be better from next time if you could post portal related queries in the EP forum to get quicker responses and ep related guidances.

Fire event between 2 process

Is there any way to implement event between 2 process?
JMS is a very good library. However it's so big
I want a library to help me to implement the following scenario:
1.Process PA in Computer CA call a webservice WS1 in Computer CB
2. WS1 send a message M to process PB in Computer CB
3. The Process PB don't need a loop to receive message M. When WS1 send the message, it fire an event or do as a publisher and then Process PB handle this event or do as a subscriber
Sorry for my English

We have a real pattern guru or two or three in this forum. Or, you should read the G4 book. In Java core API, Observer pattern is implemented by java.util.Observer and Observable. But you may need a custom implementation for your purpose.

Event triggered by iView Opening in New Window

Hi Portal Developers,
I'm trying to write an iView will exist as an invisible iView on the default framework page and listen for the event of an iView opening a new window. However, I can't find an event that distinguishes between an iView opening in a new window or an iView opening in the existing content area.
For example, as a test to capture the event that is occurring, I have the following block of javascript that displays a message when a user navigates around in the Portal using some different Portal events.
<script language ="JavaScript">
EPCM.subscribeEvent("urn:com.sapportals:navigation", "*", onNewWindow);
EPCM.subscribeEvent "urn:com.sapportals.portal:browser", "*", onNewWindow);
function onNewWindow( eventObj) {
"Got an Event from: " + eventObj.eventName);}
</script>
All this returns when a I click on an iView that opens in a new window is "Navigate", which is no different from when an iView is clicked that does not open in a new window. I've looked through the SAP-delivered javascript files and I've also done an HTTP Trace hoping to find exactly what is happening when an iView is launched in a new window.
A trace I ran indicates that the js13_spcf.js file is called when an iView is launched in a new window. In this file, I see that there is a "mode" parameter that is passed to the "Navigate" event that I'm subscribing too. For the Open in New Window option, this seems to be set to a value of 2, which makes sense. Is there anyway I can read this "Mode" value of the event that is raised as I subscribe to the event from my iView? Any other suggestions are welcome as well!
Thanks!
Matt

Hi Matt,
For an iView opening in a new window to communicate with an iView on the default framework, a "bridge" needs to exist.
That's where EPCMPROXY from epcfproxy.js comes into play.
In the iView that is opening up in a new window, you can raise an event such as,
var win_id = EPCMPROXY.getUniqueWindowId();
EPCMPROXY.raiseEvent("urn:com.sapportals.portal:browser", "", "", win_id);
Hope it helps,
