Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.

How can i do?

Hi,
There is something wrong in the definition of component usage in your component. Maybe you forgot to instantiate the use component, maby the name you are using is not correct. Try to find it in that direction.
Good Luck,

Context from Web-Dynpro-Component-Interface & Customer Extention Fields

Hello all,
A main component uses a Web-Dynpro-Component-Interface and defines an external maping to it. Web-Dynpro-Component-Interface has a context and a window. At runtime implementaion of Web-Dynpro-Component-Interface is provided.
All works fine, but how can i create an implementation with view which contains customer extention fields? Unfortunately only fields from context of Web-Dynpro-Component-Interface are visible. I can not even extend the context of Web-Dynpro-Component-Interface via enchancement framework.
I assume, it is possible with dynamic programming, but why is it not possible in declarative way?
thanks
regards
Paul

Hello,
I found this documentation:
Implementation of Interfaces for Customer Developments
Using interfaces in a Web Dynpro component benefits customers by giving them a clean basis for their own further developments. When creating a local development, you can implement a used interface in a separate component and add your own aspects to an application delivered by SAP.
http://help.sap.com/saphelp_nw70/helpdata/en/a9/19eebc1e2943dbb2d443095d017ae9/content.htm.
I think it must be a correct way to extend SAP programms with customer fields. Please reply, issue is very important.

Hi Muzammil Bichoo ,
when you copy the wda component, it will be copied and will be in active state, once all the components are activated means, windows, views, everything will be available.
now create application for your component, if you have more than one window(interface view) select the one which you need for the application.

Doubts while doing example on WDJ-Using Web Dynpro Component Interface

Hi
I am doing the example mentioned in the PDF file WDJ - Using Web Dynpro Component Interface Definition.
In the PDF file its mentioned the following code inside onActionCreateDC1:
g_Usage.createComponent("com.sap.wd.childdc1comp.ChldDC1Comp");
wdThis.wdGetWDCompInterfInstInterface().passInfo(
"Created Child DC 1");
I have one query that what is com.sap.wd.childdc1comp.ChldDC1Comp?Is it the component name of DC or the package name of DC?
I have deployed the application.When i click on button Create Child DC1 i am getting follwing exception:
com.sap.tc.webdynpro.services.sal.deployment.api.WDDeploymentException: Failed to load deployable object part 'com.wartsila.test.ChileDC1Comp', type 'Component' of deployable object 'wartsila.com/DP_TutWDInterfaces'.
When i click on Create Child DC2 i am getting follwing exception:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException:Failed to create delegate for custom controller com.wartsila.test1.ChildDC2CompInterfaceCfg. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Can anybody tell how can i solve it?
Is it required to deploy the two child component also that is ChildDC1Comp and ChildDC2Comp?If yes then how to deploy these two child DC as when i am tryng to create application for these two component then default plug is showing blank thats why i am unable to deploy these child Dcs.
Thanks
Susmita

Hi Susmita,
Is it required to deploy the two child component also that is ChildDC1Comp and ChildDC2Comp?
Yes , u have to deploy both the components.
when i am tryng to create application for these two component then default plug is showing blank thats why i am unable to deploy these child Dcs.
U need not create an Application for deploying the component .Right Click on ur project --> Deploy.
The problem is with ur Component, while creating a Component u should have created a Interface view and default StartUp plug.
Just check whether u have Created the startup plug for ur interface view.
Open the controller editor of ur interface view --> Select Plugs Tab .
and in the plug tab , check whether u have Default Start plug (in Inbound Plugs Table).
if there is no Default Start Plug , then click the Button New to create a Default Plug .
in the pop up window -- select Stsrt Up and Give the name of the plug as "Default".
After doing this , select the default plug and Right click on the plug -->copy and Open the window Controller editor -- > select Plugs Tab --> check whether u have default plug (in Inbound plugs) in the Window controller .
if the plug is not there , then paste the plug in the Window's Inbound Plug Table .
Hope it helps
Thanks and Regards

Calling session bean's business method through web dynpro component

Hi All,
Can anybody tell me how to call a session bean's methods through a web dynpro WITHOUT java-model or web service model ??
I have following scenario:-
1. Stateless Session bean having two business methods
2. Web Dynpro component
3.Now i want to call business methods without using any model. I have got following piece of code but I dont know how to go about it.
4.Where do i have to set JNDI name for session bean? which interface will be looked for?
5. Do I have to declare public part for EJB DC? If yes, how?
//This is inside web dynpro component
InitialContext context = new InitialContext();
o = context.lookup(JNDIName);
TestSessionbeanHome homeRef = (TestSessionbeanHome) PortableRemoteObject.narrow( o,
TestSessionbeanHome.class);
TestSessionbean beanRef = homeRef.create();
<returnValue> = beanRef.<ejb method name>
Please help to get a step-by-step approach to this case.
Thanks and regards,
Amey Mogare

Hi,
If I comment out the part that is using session bean's business method, DC is building fine.
And if I uncomment, then compiler is unabl eto resolve business method(s).
And i would like to mention that my EJB + J2EE App DC is building properly, but it havent yet deployed properly as I am waiting for data-source-alias name prefix to be configured by ERP team. So will this be a reason why Web Dynpro DC is not able to resolve business methods ??
Because Web Dynpro DC is able to resolved all interfaces of Session bean and entity bean. But when it comes to business method, its not able to resolve.
Any more ideas why it is not happening?
Pls help.
Now i went through some forum posts regarding this and found that we also need to add EJB DC to Java Build Path for WebDynproDC>Properties>Java Build Path.
I did this and now it is able to resolve business methods and DTOs as well. So to summarize I did following:-
1. Added EJB DC (complete DC) as a Used DC to Web Dynpro DC with Buid-n-Deploy-n-Run time dependency
2. Added Sharing reference of J2EE application DC to Web Dynpro DC -->Properties
This reference I constructed as follows:-
<vendorname>/<name of j2ee application as appearing under display name tag in application.xml (replacing '/' with '~')>
So my Sharing Reference becomes:- <vendorname>/reqpstapscreqpstapja_reqid
3. Added EJB DC to Java Build Path in Web Dynpro DC's properties
4. Then I added following piece of code to get object of SessionBean class
InitialContext context = new InitialContext();
Object o = context.lookup("java:comp/env/ejb/SessionRequestIDBean");
SessionRequestIDHome homeRef = (SessionRequestIDHome) PortableRemoteObject.narrow(o, SessionRequestIDHome.class);
SessionRequestID beanRef = homeRef.create();
beanRef.<business method>
But After doing this I am facing another problem :-
The build fails saying it is not able find the package for DTOs. But when I see the Component Controller's code it is not showing any red or yellow marks.
Can anybody pls help me out here?
Thanks and regards,

The Web Dynpro component cannot be generated due to serious (syntax) errors

Hi everybody,
While I was developing a web dynpro application, I had an error but I couldn't understand this error. Before I took this error message, only I changed bound one context node to another context node in a RadioButtonGroupByKey.Therefore, when I pushed activate button, I took an error message.This error message said "The Web Dynpro component cannot be generated due to serious (syntax) errors". What does it mean ? How can I find out where is the error in the application. Also, I think the reason of this error message is about a BC problem. I am waiting for your comment urgently.

Hi ,
Just delete the context (by using the context binding) and bind the field with the correct node and try to activate .
One more suggestion is that after deleting the binding and before binding to other node check it that whether that binding was properly deleted or not.Some times its not deleting the binding.
Hopely my suggestion may work.

Satya

Is it possible to serialize a web dynpro component controller?

Hi,
Is it possible to serialize a web dynpro component controller and deserialize it for use?
I have one web dynpro application WDA1 for web dynpro component WDC1. And another web dynpro application WDA2 for WDC2 will be opened in a new window triggered by a button action in WDC1.
Iu2019d like to pass the object reference of WDC1 component controller to WDC2.
I first tried to use a static member of a class object but found out that even the static member is initialized and set in WDC1, itu2019s still initial when I access it in WDC2.
Then I searched the forum and found one article Passing Object ref to Webdynpro Application while calling from BSP screen .
The recommended way is to serialize the object reference and store in a DB table, later on read it out and deserialize it for use.
I tried serialization using the following code, but when itu2019s deserialized, the result is initial.
Can anyone share some ideas on this?
Serialize
data: ostream type string,
           xslt_err type ref to cx_xslt_exception.
***** serialize model class
try.
      call transformation id
      source model = wd_comp_controller
      result xml ostream.
    catch cx_xslt_exception into xslt_err.
endtry.
Deserialize
    data: istream type string,
          xslt_err type ref to cx_xslt_exception.
    istream = ls_db_sel-obj.
    data lr_wdc type REF TO ZIWCI_BY_WDC_SERIALIZE.
    try.
        call transformation id
        source xml istream
        result model = lr_wdc.
      catch cx_xslt_exception into xslt_err.
    endtry.

When you say new window, I assume you mean new browser window. This is a separate user session then. This is why the singleton pattern doesn't work. Have you considered using a new dialog window instead of a new browser window. It will be modal, but will share the same user session as the parent window.
>Why do you choose this approach over cross-component usage ? component usage is the way webdynpro components are >to be reused.
>You can also consider using Singleton OO pattern class to share data between these two components.
Neither of these approaches will work if you are using separate browser windows. Such an approach results in two separate user sessions (perhaps even running on different application servers depending upon how you have load balancing setup) and therefore can't share data using either of these approaches.
In general the idea of serialization and then writing the string ito a server cookie or other database table is sound. I don't think you should try and serialize the component controller, however. Serialization only saves and restores public attributes - not protected or private ones. So in general a class has to be designed for serialization. The component controller is much too complex and wasn't designed for such an operation.
I would suggest instead extracting the data you want to share out of component controller or context and serializing it into a custom class and passing that to the other component.

Web Dynpro component - Flat file upload

Hi,
We have a requirement to upload a flat file to Planning cube (real time cube) through Web Dynpro component.
Web Dynpro component which we have developed is able to read the records from the flat file.
Now, the issue is u201CHow can we save the records read from the flat file to planning cubeu201D?
If anyone has worked on the similar requirement, pls reply. Thanks in advance.
Note : We have a planning sequence which will be executed on the click of UPLOAD button.
This planning sequence has a filter on Infoprovider (cube which we are using for planning) and a planning function of type u201CFile uploadu201D in which we have defined the flat file format.
Aggregation level is made on Multiprovider which has 2 underlying cubes (One is realtime and other one is standard).
Is there any function module in which we can pass the name of the flat file so that it will be uploaded in planing cube?
Regards,
Ankur

You can deploy solution provided by Marc Bernard within following SDN's contribution:

How can we call methods of one web dynpro component in another one

Hello Team,
How do I call one Web Dynpro component methods in another Web Dynpro component.
How do we use public parts.
thanks

Hi,
You want to use Comp2's getData() method in Comp1
If both the WebDynpro components are in the same DC:
1. Create a wrapper method (with the same signature) in the Comp2's Interface controller. And invoke the Component contorller's getData() method in this method using the below code.
wdThis.wdGetComp2Controller.getData()
2. Now Go to the Comp1 and right click on UsedWebDynproComps and add this Comp2 as a UsedWebDypro component.
3. Now go to the Component Controller of Comp1 and in properties tab add the usage declaration of Interface controller of Comp2.
4. Now using this below code you can access the method of InterfaceController of Comp2.
wdThis.wdGetComp2Interface().getData();
If both the WebDynpro components are in different DCs:
1. Right click on Comp2 and select Add to public part on Comp2 in DC2.
2. Now Add this public part in DC1 UsedDCs.
Now repeat the above stpes 1...to..4. of "If both the WebDynpro components are in the same DC" same.

Changes in standard e-rec web dynpro component

Hi ,
I need to make some changes in standard e-rec web dynpro component. Needed to know what approach needs to be followed for the same. Can I make changes in the standard itself or do I need to copy the standard component and make changes in the Z component.
Thanks in anticpation.
Regards
Nidhi Jain

Hi Nidhi,
Its better to make changes in the Enhancement Framework itself.It will be too complex to make it to Z applications since there will be lot of dependent objects involved. I was also in the state of dilema when i was about to make changes to the standard E-travel applications using ABAP webdynpro(EHP2) and finallly i was able to meet all the customer requirements using Enhancement Framework and yesterday the UAT ended successfully..:-).
I have also implemented the e-recruiting using BSP in my last project.So i am able to give the above suggestion to you.
Since E-rec applications will have lot of methods, you can be able to meet all the changes in the Pre and the Post exit methods itself.
All the Best.
Thanks,

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

SRM 7.0 find transparent table name from Web dynpro Component

Hi ,
I am trying to find the transparent table name from Web dynpro component dictionary structure. I am working in SRM 7.0. Please let me know how to find the transpartent table for a field.
Thanks,
Monica

hi,
your question is very unclear and does not relate to performance.
SRM uses webdynpro ABAP so the recommendation will not help.
Do you need a technical UI element?
Or the application table where the business data of an UI is stored???
If it is the later, then you can use the SQL trace, change to element you are interested in, and trace it. The table should appear in the trace in connection which an UPDATE command. Still a bit cimbersome.

Problem in changing CAPTION (header) of a View in Web dynpro component

Hi All,
I want to change the Caption (header) text of a View in Web dynpro component. But when i transport it the changes are not reflecting in other systems.
Also when i activate the Web dynpro component in development system, it issues a message "The text belongs to package $TMP". But the Web dynpro component is assigned to a custom package.
Any pointers to resolve this is appreciated.
Thanks in advance.
Regards,
Navin.

Hi
Please check the 'text' property of the caption.
e.g : If you are using OTR to bind the text then it might be possible that the OTR text belongs to $TMP package.
Please explain how have you binded the caption ?

Puneet

No executionContext attribute in Web Dynpro Component Controller

Hi All,
    I'm trying to write a Web Dynpro Component which can be used as a callable object by following the Link:[document|http://help.sap.com/saphelp_nw70/helpdata/en/43/e085d6421a4d9de10000000a155369/frameset.htm].
    I've successfully finished the getDescription method. In the execute method, I'm trying to get the executionContext attribute of the instance, but it always shows that no attribute name executionContext can be found here.
    Anyone can help me?
    Thanks,
YiNing

Hi,
You should get the executionContext attribute as an inout parameter of the execute() method. You can also declare a instance variable to hold this to be later refered in other methods of the controller.
Thanks,
Dipankar
