Events for web dynpro UI elements

Hi,
In NWDS there are only a few event types associated with each UI element type. Say InputField has 'onEvent' event, DropDownList has 'onSelect' etc.
So, for the Input fields are we limited to triggering an event handler to fire only when the user hits the 'ENTER' key? What do I need to do to trigger an event handler for say when the user hits a 'TAB' key ? Is there some way we can extend the event listener interface to add more events to an UI element ?
Please advise. Thanks !
Sri

There is no event triggered when the input field looses focus.
You cannot add your own events.

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

Want docs for Web Dynpro ABAP

Hi All ,
Can anyone please send me the Docs or link for Web Dynpro ABAP .
Thanks in advance
Rahul

Hi,
Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
? The use of declarative and graphical tools significantly reduces the implementation
effort
? Web Dynpro supports a structured design process
? Strict separation between layout and business data
? Reuse and better maintainability by using components
? The layout and navigation is easily changed using the Web Dynpro tools
? Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
? Automatic data transport using data binding
? Automatic input check
? Automatic operation of the Web Dynpro application using the keyboard
? User interface accessibility is supported
? Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
? Clear separation of business logic and display logic
? Uniform metamodel for all types of user interfaces
? Execution on a number of client platforms.
? Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
? Data flow between the front end and back end
? Layout of the user interface
? Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
? An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
? An interface for calling Web services
? A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
? The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
? The view is responsible for the representation of the data in the browser.
? The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Handling standard iview event from web dynpro

Hi all,
I hav w a search iView which is SAP standard, when you click an element on the result list it triggers an event. The link contains the following:
javascript:{jsCode="
EPCM.storeClientData('urn:com.sap.bor:BUS1001','objid','12002');
EPCM.storeClientData('urn:com.sap.bor:BUS1001','AllKeys','objid');
EPCM.raiseEvent('urn:com.sap.bor:BUS1001','select','','a very long url');"};if(opener!=null&&self!=opener){opener.execJS(jsCode);}else{execJS(jsCode);};
On the other side I'm developing a custom WebDynpro iView whick needs to handle this event. By adding to wdInit() the line WDPortalEventing.subscribe("urn:com.sap.bor:BUS1001", "select", wdThis.wdGetGetReportsListForMaterialAction()); I was able to catch the event. But I can't get the parameters from the event.
For what i've learned browsing the forum the javascript code above stores the parameters in the "client data bag", and are not directly passed in the event.
Is there any way to retrieve these parameters from the Web Dynpro iView ?
Thanks in advance,
Diego.

Hi all,
As a workaround I made a Portal Component application which receives the event and parameters from the standard iView and lanuchs a new event setting the aprameters in the event as Web Dynpro expects them (without using the client databag). Then I inserted this Iview in the same page as the others, but hidden. It's not elegant but is working.

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in

Owen

On Blur, On Click Events in Web Dynpro - How can it be done ?

Hello All,
I am wondering if it would be possible to have
On_CLick
and
On_Blur
events using Web Dynpros, it would be great if any one can tell me how it is done or provide me some documentation, I have done it using HTMLB but dont know how to do it using Web Dynpros.
I would appreciate any help.
Best Wishes,
John.

Hi John,
As Maksim said you can use the onClick event with some of the UIElement.
for example:
Add a button UIElement to your view
create a new action in the view.
Write in the action something like:
wdComponentAPI.getMessageManager().reportSuccess("Hello John");
In the properties of the button you will see an onAction event. Bind it to the action that you created.

Coding standards for Web dynpro ABAP

Hello all,
Can anybody please help me by providing the code review checklist for Web dynpro ABAP?
Thanks and Regards,
Rohini Shankar

Hello friend,
WebDynpro     *
1     Do not implement Data intensive operations in UI layer
2     Avoid database selects in the WebDynpro code.Use the corresponding BAPIs ,Methods
3     Are ABAP OO Classes like Assistance class are being used for application coding ?
4     Are Windows/Views only used for the sole purpose of hosting views and context?
5     Are a reasonable number of views put in a single WD Component instead of creating multiple WD Components ?
6     Unneccessary usage of dynamic programming and dynamic component avoided
7     Are singleton nodes used in case of nesting in the context ?
8     Is deep nesting of containers, Groups and Tabstrips avoided ?
9     Is the UI element TreeByKey or TreeByTableNestingColumn used instead of the Tree UI element ?
10     Is the checkbox "Accessibility Checks Active" ticked in the WD Component properties
11     Are the WD Component Instances deleted when no longer needed (IF_WD_COMPONENT_USAGE=>DELETE_COMPONENT)
12     Are the OTR texts defined for all the labels, texts(where ever appropriate) in properties of all the UI elements
13     Has the Generation limit been checked for all the components developed
14     Sufficients commets are written at the beginning of every major block to explain the processing logic.
*Error Handling     *
1     Is SY-SUBRC checked after CALL function modules
2     Use Assertions if you face unexpected errors which usually never ever occur!
Extended Check and Clean Up
1     Have following been removed :
     ·      Unused variables
     ·      Unused text elements
     ·      Unused tables from TABLES statement
     ·      Commented out parts of the code
     ·      Code segments which do nothing
2     Is extended program check completed and all errors/warnings removed
These are the things which i used for my project.

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 call custom themes for Web Dynpro ABAP Application?

Hi,
I need to change the appearance of Web Dynpro ABAP application. So far I followed below steps,
1.     Created theme folder u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019 ).
2.     used program BSP_UPDATE_MIMEREPOS to dowmloaod content of u2018sap_tradeshowu2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> sap_tradeshowu2019) to desktop.
3.     Modified the themes using Eclipse Theme Editor.
4.     used program BSP_UPDATE_MIMEREPOS to upload modified themes to MIME repository u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019) .
My current URL is like http://server.name:XXXX/sap/bc/webdynpro/sap/hrrcf_a_startpage_int_cand?sap-client=XXX.
Now I want to know how custom themes called for Web Dynpro ABAP Application.
Is my approach correct?
...Naddy

Hi Naddy,
What you used is one way and even I failed when tried that method,
Instead go to SE38 - WD_THEMES - and you need to upload the zip file and you need to follow a folder structure.
it is case sensitive, atleast the zip file.
Make a zip file by name "Project.zip" -
Create a Folder Project and have the below folder structure,
1 data - all the properties files and also the designinfo file, below is the code
2 themes - (to get all the files download the theme from portal and you will have all the folders)
   2.1 ur
     2.1.1 name of the theme
       2.1.1.1 common
       2.1.1.2 csf
       2.1.1.3 r
       2.1.1.4 ur - all the css files (would be good if you can get the files from the server.)
       2.1.1.5   WSRP
3 war - empty folder
*.designinfo
isVisible=true
version=7.0.14.1.0
isDefault=false
isSapDesign=false
designName=**** name of the theme
Once done create a zip file and click on Start Import and give the path and will ask for transport request, it will take a while to upload once done as mentioned in the use the parameter sap-ep-themeroot="path"
This will resolve the issue.
Cheers-
Pramod

SAP tool to estimate time for web dynpro development project

Hi,
Is there any standard SAP tool available to estimate time for web Dynpro development project?
Thanks and Regards,
Deepti

Hi Deepti
An implementation of Webdynpro based UI could be estimated by a 'standard' technique like any other U:
1. Try to count the number of views/screens/popups in your application. The estimation time will be proportional to the quantity.
2. Try to count the number of external interfaces would be used in the application. For example, quantity of necessary BAPI invocations (RFC), quantity of Web-service invocations or EJB calls. Also quantity of native JDBC queries if any.
Test = Nviews x Hview + Nint x Hint, where Hview & Hint time in hours for average implementing of one UI view and time for adding of average service invocation.
BR, Sergei
