Fire event in web dynpro java

Hi,
I want to fire events in code e.g. sorting of table columns. I'm sure I cannt call event handler with null parameter here.
Can anybody please help here?
Thanks in advance.
Rgds,
Atul.

Hi Kishan,
I think I'm confusing you. i do not have any controller usage.
below is my event handler method:
public void onActionSortTableColumn(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
TableAccessories Accessories = wdContext.currentcontextElement().getTableSorter();
Accessories.onTableEvent(wdEvent);
I just want to anyhow call this method, without wdEvent being null.
Is there any way I can fire the event and this method get called OR to create wdEvent to call this method directly?
Rgds,
Atul.

Portal Eventing between Web DynPro Java iView and non-Web DynPro 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 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?

hi
Please write the below code snippet in ur jsp for notifyTestjavascriptfunction
function notifyTest( eventObj ) {
     eventParameter=eventObj.dataObject;
     // code to print the parameter "eventParameter"

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

Problem in completing the TASK when using Web Dynpro Java and BPM

Hi,
I am using Web Dynpro Java and BPM.
i see my Web Dynpro View when i run the process.
Just that the task is not completing.
when i click on the Web Dynpro button to signal the completion of the event, nothing happens.
i have appropriately created events in both Component controller and Interface Controller and used the same in creating the Task.
a method in Component controller fires the event and a button click in the view calls this method.
i have successfully completed Donka Dimitrova's "SAP Netweaver Business Process Management-End-to-End Process Implementation Sample " but when i tried my own with slight modifications, it is not working !!!

Hi Amol,
The way you described the things, I dont see any problems. Just to make sure that you are triggering the right event that you mapped as completion event for the task, try to cross check once again and see if the correct event is getting triggered. Also try to put some messages for debugging to see till where the control goes.

Problems with Adobe PDF forms in Web Dynpro Java

As of now , I have two major issues in developing Adobe PDF forms in Web Dynpro Java .
1.Text getting wrapped and repeated from the first line :
Any text field that flows to the next page gets wrapped at the end of the page and is again printed on the next page beginning from the first line .
For eg:
If I have 4 lines in a text field that is at the end of the page
1111111111111111111111
2222222222222222222222
3333333333333333333333
4444444444444444444444
and the page holds space for only two lines it prints the lines
1111111111111111111111
2222222222222222222222
in the first page and then proceeds to the next page and prints
1111111111111111111111
2222222222222222222222
rather than printing
3333333333333333333333
4444444444444444444444
2.No way to hide a page at runtime:
It is not possible to hide a page in a PDF form at runtime . If scripting is used , the page turns into a blank page but not hidden .
Any pointers on this????????
Helpful answers will be suitably rewarded with points!!!!

Yes,I am using the versions that you mentioned.
I have a node called MasterData which is the root node for my PDF Form.I have a node called GenData inside this node whose ctx_Appraisal_Type_Num attribute is bound to a hidden TextField in my form.In the docReady event of this TextField, I am writing the following FormCalc script to hide my SubForm whose Id is MngrCmptnc
if(MasterData.GenData.ctx_Appraisal_Type_Num == "2")
then
MasterData.MngrCmptnc.presence = "visible"
MasterData.MngrCmptnc.MngrCmptnc.presence = "visible"
MasterData.StrImp.presence = "visible"
else
MasterData.MngrCmptnc.presence = "hidden"
MasterData.MngrCmptnc.MngrCmptnc.presence = "hidden"
MasterData.StrImp.presence = "hidden"
endif

SUBMIT(to SAP) Button in Adobe Interactive Forms (Web Dynpro Java)

Hi ,
I m using Adobe Interactive Forms with Web Dynpro Java
But submit to SAP button is not working
i m using NWDS 7.2 with adobe lifecycledesigner 6.0
with adobe reader 9.0
when i click submit to SAP button in interactive form nothing happens and
data is not transfered into web dynpro Context
Can anybody help me out................

Hi Adi,
The evniorment and versions you posted seems to be quite scattered, make sure all are of compatible and to the lates.
Anyways this was not the reason for your problem.
Can you tace if the button click event is triggered ....?
1) when the PDF is published can you see any of the fields editable...? reason behind is generally when you create a form in ADLC it comes up in static PDF format if its so you need to make it dynamic.
I dont know if adding the webdynpro script to your form might fix.

How call key Function in WEB Dynpro Java?

Hi,
Somebody know how to call key Function(F1, F2, ... F12) in WEB Dynpro Java to launch and Event?
Thanks in advance.

Hi,
You can WDHotKey property to define the different keyboard shortcuts to enable the user to trigger events with key combinations.
When the user presses the key board shortcut defined as the hotkey then onAction event is triggered.
The keys F2, F3, F4, F5, F6, F7, F8 and F9 are not supported, they call predefined functions provided by the Web Dynpro Framework.
The complete list of supported shortcuts is here:

Controlling visibility of Web Dynpro Java iView in portal WDJ page

I should be able to use the WDPortalUtils interface in my Web Dynpro Java DC application to get the name of the iView in my Portal WDJ page using IWDPageService method getVisibleIViews(). My intent is to add another iView to this page and programmatically control the visibility of each iView from my WDJ application.
-> Instructions I have found through my online research indicate I should not have to specify a sharing reference because I am using the WDJ framework, but I tried it anyway. It didn't work.
-> I have added DC epbc.prtapi._api public part to my used DC's, and specified dependency at both Build time and Run time.
-> My portal page template is of type Web Dynpro Proxy Page.
-> My iView template is of type Web Dynpro Proxy iView.
-> The Page Content view of my page shows the 'visible' checkbox set for my iView.
The following statements in the wdDoInit() method of my DC's view controller should return the portal name of my iView:
IWDPageService pageService = (IWDPageService) WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE);
String[] iViews = pageService.getVisibleIViews();
I get no compile time errors or runtime errors when I execute these statements.
BUT...
Instead of a String array, I get back a memory space pointer.
Example: [Ljava.lang.String;@664e664e
What am I missing?

Hi Jennifer,
That's what this forum is all about; finding solutions to hard-to-solve issues, which might also help someone who may face the same issue in the future. So I hope my input is valuable
The last thing I can think of is the method is been called before the portal page has been rendered completely, which may lead to the faulty results.
Is it possible to move the getVisibleIviews() to a method which is called later in the phase (for instance, at the bottom of wdDoModify or wdDoPostProcessing) or, even better, in an onAction event handler when a button is clicked?
If this doesn't work I'm afraid I'm running out of options and i would file an OSS message with SAP
Hope this helps!

also go through the following
Using the FunctionKey
Use
The FunctionKey allows you to trigger a Web Dynpro action using a specific key on the mobile device. In the following example, this UI element is used to navigate to another view via a specific key.
Prerequisites
●     The SAP NetWeaver Developer Studio is installed on your computer, and you can use it to create your mobile Web Dynpro application
●     You have access to a SAP NetWeaver Application Server, where you are running the Web Dynpro application
●     You are using a Pocket PC with special scanning equipment manufactured by Intermec Technologies or Symbol Technologies
●     You have created two views in a Web Dynpro project and called them StartingView and TargetView.
Procedure
       1.      Navigate to the StartingView and double-click the view or choose Edit from the context menu.
       2.      Insert the mobile UI element FunctionKey.
       3.      Switch to the Plugs tab, create an outbound plug with the name fromFunctionKey and define the navigation link to the TargetView.
       4.      Switch to the Actions tab page and define an action called NavigateToAnotherView.
       5.      Assign the value IBrowse_OnKey49 to the keyCode property of the FunctionKey.
       6.      Assign the NavigateToAnotherView action to the onAction event of UI element NavigateToAnotherView.
       7.      Switch to the Implementation tab and add the following source code to the implementation of the view controller. The read data is passed to the context and the relevant context attribute is set.
public void onActionNavigateToAnotherView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
   //@@begin onActionNavigateToAnotherView(ServerEvent)
   wdThis.wdFirePlugFromFunctionKey();
   //@@end
Result
By pressing press key 1 on the mobile device, you navigate to the TargetView.

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?
Regards,
Thomas
PS: The 7.0 procedure, which can be found in various posts, doesn't seem to work any more for CE 711.

Date Column not getting sorted in a table in web Dynpro Java

Hi All,
I am facing an issue while sorting the date column in a table in my web dynpro java application.
When the date is displayed in the sql format in tha table, I am able to sort the date column successfully but when we convert the date field from sql format to util format in our table and then sort it does not work.
Kindly let us know the steps to be followed in this case to sort the date column of a table in Simple Date format as we do not want date in the sql format to be displayed.
Thanks & Regards,
Anurag

Hi,
You might want to check whether both your browser's language settings are identical. The browser language could also determine the date format.
As a workaround, you could add an extra attribute to your context, and set the calculated property to 'true'.
In your table, add a new column and bind to this new attribute, and hide your original date column
If you sort using the date column that's hidden now, you could use the calculated field to fixed-format your date the way you prefer (by using the SimpleDateFormatter class for instance)
Cheers,
Robin

Hi Amit,

This is what you're looking for, there's no real cook-book -- though Amey mentioned there might be some material on SDN, perhaps some tutorials.
You should be looking into com.sap.security.api.IUserFactory, methods newUser(String) which gives you and IUserMaint and commitUser(IUserMaint, IUserAccount) -- IUserAccount can be obtained using com.sap.security.api.IUserAccountFactory, method newUserAccount(String)

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
 I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
 procedure"
 Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
 signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks
