Web Dynpro Model help

I have a Web Dynpro application in which a user will enter information and click a button to call an RFC. The RFC then returns data to a new view. The user can make changes to this view, and will hit a button to call a BAPI. I am using a custom controller. I am not sure how to feed the results from my RFC to my BAPI. Can someone give me some pointers as to where to begin?

Hi Maz,
Follow This Procedure,
Create Model:

Error when Creating Web Dynpro Model in CAF-Service

Hi All,
I reaaly need help. AFter updating to SPS 9, it was necessary to redeploy my Entity Service. That contains to "Create a Web Dynpro Model" in the Service Explorer,
to get an interface of the Service in my Web Dynpro Application.
Before I update to SPS 9, the Application works fine.
But now, when I want to "Create a Web Dynpro Model" in the NWDS I get the following Error-Message (its not a useful Error-Message):
Error cannot create Web Dynpro Model:
Creation of Web Dynpro model failed. Reason: null 
Thanks for helping me
Steve

Hi Aliaksei,
the problem in the thread is the same I got.
When I use only 7 letters for the operation name, the creation work. When I use more then 7 letters the creation doesnt work.
But its hard to find a methodname with only 7 letters.
In SPS 8 I didnt have problems with the length of method names. Why is it so?

Hi there,
I've recently installed the latest Netweaver'04 Sneak Preview and I get the following exception when generating an R3 Adaptive RFC model (using the "create model" Wizard):

Web Dynpro Model Generation for Application Services

Hi Experts,
I'm currently experimenting with the new functionality provided by CE, but there is one thing that I can't seem to figure out. How does the new Web Dynpro model generation work with regards to CAF Application Services? I'm trying to call an application service from a web dynpro application, but it seems as if models are completely different from Netweaver 7.0. What type of model do I need to create? Do I have to expose the application services as web services?
I've tried creating an EJB model and then binding the model to the context, but I kept receiving null pointer exceptions when doing this and I'm not sure if this is the correct way to do this. Can anybody point me to some good documentation on Web Dynpro/CAF interaction in CE?
Thank you,
JP

Hi JP,
You are right, the CAF models are completely different in NW CE 7.1 compared to NW 7.0.
CAF Application Services in CE 7.1 are in fact EJBs. So the EJB model importer is the way to go. You can find <a href="http://help.sap.com/saphelp_nwce10/helpdata/en/45/dd45e4bc295595e10000000a1553f7/frameset.htm">documentation</a> and some <a href="http://help.sap.com/saphelp_nwce10/helpdata/en/45/f7f744aea471fae10000000a1553f6/frameset.htm">tutorials</a> on help.sap.com. If you still have troubles after you go thru these, please post your concrete issues and I'm sure we'll be able to figure out what's been going wrong.

Web Dynpro Model Usage Error

Hi All
I have created Web Dynpro Model out of my CAF project. I followed this <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/8b7059da-0c01-0010-e09c-9ecabaf58864">tutorial</a> to create Web Dynpro model and use it in other DC. In the other DC, I added all the other required DCs mentioned in the tutorial such as caf/core/dict, caf/ui/ptn/common and tc/col/runtime with each of them havin dependency type as build and deploy.
After I do model mappings in controller and view, deploy and run the application, I m gettin the following exception
"java.lang.NoClassDefFoundError: com/sap/tc/col/client/generic/api/IQuery "
Has anybody ever got this exception ?
any help on this will be appreciated with points

and then add following two in library reference in webdynpro refrence,
if your using the GP interface we have to include the "cafeugp~api"

Adding a Web Dynpro Model on a Composite Apllication Component in CE 7.1

Hi experts,
I am trying to add a web dynpro model to a Composite Application DC.
I am using SAP NW CE 7.1.
In CE 7.0, this was done by simple right click on the CA DC.
but i am not able to do it in CE 7.1.
Can somebody tell me how do i add a web dynpro model to a composite application DC???
basically i need to add a UI corresponding to a composite application?????
Cheers
Gaurav Raghav

Hi Srinivasan Subbiah,
The option you just mentioned is disabled.
how can i enable it???
Also let me explain what i need.
I have a 3 step process where in a user fills a form and sends it to his manager, who appoves/reject it based on some criterias. then the approval/rejection alert is send back to the user.
Now i need to develop the UI as well as Business Logic for this process.
How do i go about it?????
I can develop the UI in a Web Dynpro DC and the Business Logic in a Composite Application DC. How do i associte one with the other????
In CE 7.0, this was achieved by addind a Web Dynpro Model in the Composite Application Project. How do i acheive the same in CE 7.1 ?????
Thanks and cheers

Hi Peter,
We have already faced this problem in our company with Windows Vista machines. So, if you have Windows Vista, try to run NWDS under Administrator account and in Windows XP compatibility mode...
If not, probably you should re-install your NWDS.

Quick Question: ABAP web-dynpro model relies on JCO?

Hi gurus,
As mention in subject. Does ABAP web-dynpro model relies on JCO?
Did a quick search without solid answers...

JCO, is Java Connectors to connect SAP from Java world
You don't need any JCO when you are in the same ABAP Stack
There is no model Nodes/Attributes in Web Dynpro ABAP as in Java, because you are in the same ABAP Stack

Creating web dynpro model from XMII web service

Hi All,
need some help, after creating model in Web Dynpro from XMII WSDL file everything is fine but when i execute the service. I'm getting the following error:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlUnmarshalException: XML Deserialization Error. XML is not valid. Element [http://www.sap.com/xMII]<OutTxRecordSetXML> is required in <OutTxExecutionMsg> but can not be found.

Inheritance in Web Dynpro Model

Hello
This is the current situation:
I have 3 JPA entity classes much like these (including constructors, getters, setters, ...).
@Entity
public abstract class OuComponent {
@ManyToOne
private Ou ou;
@Entity
public class Ou extends OuComponent {
@OneToMany
private Collection<OuComponent> ouComponentCollection;
@Entity
public class Person extends Component {}
In the database, OuComponent has a discriminator column.
This structure appears to work in a normal web module and an EJB Module.
In Web Dynpro, using a model, I can create a new Person and attach an existing Ou to it (through the inherited property ou from OuComponent).
However, when I try to display the information, I recieve the following error:
java.lang.IllegalArgumentException: Cannot perform write operation 'setRelatedModelObjects' on target role: Class 'Person' is not compatible to class 'OuComponent' of target role 'ouComponentCollection' in model class 'Ou'
It appears that Web Dynpro does not realise that Person is actually a subclass from OuComponent. I think it simply checks the discriminatorcolumn for the word 'OuComponent' and throws this exception because it finds a related entity of the type Person instead of OuComponent (even though, as stated, Person IS-A OuComponent. Web Dynpro just seems to ignore it).
How could I bypass this?
Thanks for your feedback

Hi Vincent.
Have you resolve this problem? If yes, could you post the solution?

Web Dynpro - FITV_POWL_TRIPS Help

Hi,
My Client's travel policy establishes maximum daily limit for the reimbursement of meals. Standard SAP enforces maximums at receipt level, but cannot sum receipts and enforces a daily maximum. Since as associate will mostly likely have several meal receipts for a single day, Client want summarize these receipts and flag a policy violation (with warning message) if the daily limit has been exceeded.
We are implementing ESS/MSS and for travel expenses we are using Web Dynpro Application - FITV_POWL_TRIPS.
Please let me know how to achieve summarized check on daily max limit.
Regards,
Amey

I have some other iviews on ESS personal information like addresses and once it is changed/edited by employee on portal I have to shoot an email to HR department.
So is there any enhancement I can use to achieve this functionality.
And thanks for your previous inputs, it was useful.

Calling Web Dynpro-Model of Application-Service doesnu00B4t work.

Hello!
I have created a Composite Application with Entity- and Application-Services. I have also created the WebDynpro-Model and use it in another WebDynpro application to call the services.
I have a Entity-Service 'PollCatalogue' and an Application Service 'PollCatalogueApp'.
When I call an Entity-Service to create an entity, it works:
APollCatalogue pollcat =
 PollCatalogueServiceProxy.createPollCatalogue();
 pollcat.setName(name);
 pollcat.getAspect().sendChanges();
 IServiceFacade serviceFacade;
 serviceFacade =
 CAFServiceFactory.getServiceFacade(diplDefinition.class);
 serviceFacade.save();
But when I call the create-Method of the Application service nothing is created:
the call is similar to above except that
PollCatalogueServiceProxy.createPollCatalogue();
is replaced by
PollCatalogueAppProxy.createPollCatalogue();
Anyway I don´t understand what is done behind the scenes. My create-Methode has one parameter name, because it is a business key. But the ServiceProxy-create-Methods do not provide a name parameter. What service-methods are called when service-facade.save() is called? In case of Entity-Service-Proxy seems to be the create method. But what if I change more than the key-parameter, what else is called? update? And in case of AppServiceProxy? ???
Does anyone understand what is going on here?
Thank you for your help.
Best regards,

Hi Jorg,
About getting an exception:
IQuery query =... ;
query.execute() ;
IMessageList mList = query.getResultAspect().getMessages()
if (mList.size() > 0) {
 for (int i = 0; i < mList.size(); i++) {
 IMessage mes = (IMessage) mList.getMessage(i);
 Throwable ex = (Throwable) mes.getExtension();
 ByteArrayOutputStream bAOStream = new ByteArrayOutputStream();
 PrintStream pStream = new PrintStream( bAOStream);
 ex.printStackTrace(pStream);
 //use bAOStream in order to show stacktrace
Regarding conceptual background about Models and Proxys:
You can find some infomation about wd model:
<a href="/people/valery.silaev/blog/2005/09/09/common-model-interface Model Interface</a>
<a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/cef4f43e-0d01-0010-db84-ede25c874115">WQhy to use webdynpro common model interface ?</a>
I don't know about some proxies documentation. Possible it does not exist. So, there is brief information about it:
CAF data access services - comcafruntime~uicoupling DC. There is an implementation of com.sap.tc.col.client.generic.api api. These interfaces extends generic CMI interfaces. On top of CAF data access services implementation CAF designer generates typed CMI models which you finally use. For supporting of typed CMI models CAF provides additional build-in functionality GCP(generic client proxy) which directly operates over com.sap.tc.col.client.generic.api generic implementation.
I recommend you to learn CAF data access implementation and read information about CMI model. That's not huge area and it gives you necessary understanding.
Best regards,

P.S. I don't recommend to learn and investigate the GCP implementation. That's just loss of time. The only thing that you need to know there is a black box layer which converts generic CMI model to typed model. Actually you can use generic model directly without typed. To do this use the following method for service facade getting:
com.sap.caf.ui.utils.cool.CAFServiceFactory.getServiceFacade() ;
but not this one:
com.sap.caf.ui.utils.cool.CAFServiceFactory.getServiceFacade(final Class modelDefinition) ;
and also do not use generated proxies at all, just use CMI api for model info setup for model nodes and other generic CMI api.
