Web Dynpro Help

I have a view that reads in a material then does an RFC to see if the material is a valid material. If the material is valid I display the reuslts. If the material is not valid, I want to return back to the previous view but not sure how to do it. I have a work around, but want to know if I can return to the previous view if the material is not valid.

Hi,
Correct me if my understanding is worng.
In view 1 you are reading a material and you are checking whether the material is valid or not in another view.
If its valid then show the result otherwise return to view1.Right ??
In that case create a outboundplug from View2 to view1 and fire the plug !!!

Web Dynpro is the SAP programming model used to develop professional Web UIs for business applications. It consists of a runtime environment and a graphical development environment with special Web-Dynpro tools that are integrated in the SAP NetWeaver Developer Studio.
The Web Dynpro tools support application development during the implementation and design phases. When a Web Dynpro application is developed, a platform-independent metamodel is created from which Java classed are generated.
Since Web Dynpro features a clear separation between layout data and business data, you can develop Web Dynpro applications with the same programming model both for mobile devices and conventional PCs.
WebDynpro Provides Application Developers the following advantages:
1.Web Dynpro supports a structured design process
2. Strict separation of layout data and business data through use of the Model View Controller concept
3. Different implementation languages are supported
4.The use of declarative and graphical tools significantly reduces the implementation effort
5.Reuse and better maintainability by using components
6.Syntax check at design time
7. Automatic data transport using data binding is also possible.
8.Automatic input check.
9.Flicker-free screen construction.
10. Ensuring platform-independence with the meta model approach
11. Minimizing the implementation effort through declarative programming
12. Supporting a structured design process by applying the model view controller paradigm
13. Providing reuse and better maintainability by using components
14. Providing graphical support with tools in the Web Dynpro perspective
15. Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.

Type Mapping in Web Dynpro

Hi there,
rather a Web Dynpro newbie, I have scanned the documentation and forum threads to find whether there is something like a type mapping mechanism (say, your web service automatically creates Calendar attributes from xsd:dateTime elements, and you want to display them as dates in your view), but it seems there isn't.
I have to do such type conversions by myself (by providing additional value attributes to my context node and populate them after executing the service call), right? Or did I overlook something?
Regards
Nils

Hi Nils,
define calculated context attributes of type readOnly=false for this purpose. In the generated getter and setter methods you can implement your own format (getter) and parse (setter) logic (or type mapping like you call it).
Excerpt from the Web Dynpro Help:
Application-specific validations: You can use the setter and getter methods that are generated for writable calculated context attributes to format as well as parse and validate data application-specific. You can check the user input in the mutator method and save it in a separate, non-calculated context attribute. An error message is displayed if this is not successful. If you want to display the input value in the case of errors as well, then first you have to save the incorrect value in an additional usual context attribute, from which the access method of the calculated attribute is then supplied.
Also read thread Re: Problem with time input field about problems with time input fields.

Few basic ques on Web Dynpro

Hi All,
I have few ques on Web Dynpro basics.
1. Why is Web Dynpro said to have language-neutral metamodel.
2. What is meta-model.
3. What is declarative programming approach.
4. Why is a dictionary used. The simple type and a structure can also be declared in a Controller. Is it just a Global Declaration.
5. Where does the code of dictionary reside.
Shall be grateful for the answers.
Regards
Nikhil Bansal

Hi Nikhil
Here is the answers for your questions.
1.Why is Web Dynpro said to have language-neutral metamodel
A.the user interfaces developed in webdynpro is platform independent because of meta model/data generated by webdynpro framework is independent of all languages.This metamodel you can transfer to any system so that the application is executed in that system.So generated meta data is independent.
2.What is meta-model.
Metamodel is data about the application.Webdynpro framework have seperate tools to generate this metadata in xml files.These files contains all information about your application.Views,components,actions every thing.
Metadata/model means data about the data in general
3.What is declarative programming approach
Declarative approach is the one with out coding most of the things required to implement User interfaces (design,appearence,data) are specifying at design time by choosing right properties.So this eliminates most of the coding.So this is the declarative model.
4.Dictionary
This is again having two types like simple and structure,Here basically we store the data in dictionary datatype or populate the data in this type in runtime.Usually this datatypes are used to display the data in dropdown box or to display large data.
5>Where does the code of dictionary reside
The Dictionart classes are generated by the frame work for simple type,For complex type the data you are populating in view controlleres depending upon the conditions
For clear classification

Search Help on Adobe Interactive Form with Web Dynpro ABAP

Hi All,
I have created Adobe Interactive Form with ZCI type and XML based interface type using Webdynpro ABAP.
I placed a text field USER_NAME on the form ( data element is linked to search help USER_COMP ).
Added Native WD UI element 'Value Help' to form to search for users and changed script
*var fieldName = "INSERT_NAME_HERE*"; to var fieldName = "USER_NAME";
The problem is that when I click on the value help button, nothing happens.
Is any more additional steps required ?
Thanks

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
Kind Regards,
Owen

Search help in web dynpro

Hallo dear all,
i defined a search help in the ABAP Dictionary and want to use it in a web dynpro. The search help is based on the data base table /BIC/PSCPLPROD (selection method).
It shall be used in a web dynpro that presents select-options (among others) for the field /BIC/SFINCUST of the table /BIC/SCPLPROD.
How can i realize that the selct-options field can automatically use the predefined search help?
I must explain additionally that the mentioned select options field is alreday linked to an other search help which unfortenately is unseless in this case. So Iwant to "overwrite" this link with the link to my search help on the DDIC.
Your answer would really minimize my project troubles. Many thanks in advance.
Best regards Dorothea.

why can't you have another field and have the required search help attched to it.
if you can control this at Dictionary level then the Problems at WebDynpro side is minimum.
