Question when i am in web dynpro interface method trying to find code

Hello guys,
I am in an event handler and i see this logic wd_this->mo_dodm_srchbidder_c->add_selected_bidder(). When i double click on the add selected bidder it takes me to the method inside interface /sapsrm/IF_CLL_DODM_BIDDER. So when i double click on the method it takes me nowhere.
My question is what do i have to do or where do i go to see the code for add_selected_bidder? thank you.

I think, you have visited to the definition of the interface method and not the implementation of the method.
You have instantiated the wd_this->mo_dodm_srchbidder_c some where, may be in the wd domodifyview. Find that out where the implementation happens.
I believe when you double click the method in editor ask for to go to definition or implementation.

Web Dynpro Action/Method Handeling question

Hey guys, here is what i am trying to do:
I have a view with an input field and a drop down.
The user enters an employee number in the input field, and i want the drop down to populate with some info about that employee.
I CAN get it to work with the user pressing ENTER after entering the employee number, but i am wondering if there is a way to handle if the use just TABS to the drop down, or if the user just CLICKS on the drop down with the mouse?
Either that or a way to auto populate the drop down anytime the value changes in the text field?
thoughts?
I have tried all the standard WDDO events and none do what i want.
Thanks!
-Jason

HI
Ok.Maybe I didn't explain my question clearly.
Firstly, what I want to do is just like send-email button does.But you know,after I click the sendemail button, an automatic check will be done to check which required text field is null,if is null, a red border will be added and the submit is not allowed.(and also execute presubmit event)
Ok, I just add a web dynpro submit button,but I find it doesn't check whether the required text field is null.
I thought I could add the SAPSUBMIT script to submit button,but when i change the button to regular submit button, the click event disappeared.
I know we can add some more scripts to archive this.
But because of the form is so large, I just want to find an easy way.to do so.
Thank you.
Best Regards

Question about meta-data of Web Dynpro ABAP / Web Dynpro Java

Hello together,
everywhere I can read, that Web Dynpro meta-data is platform independent.
I´ve read into a book, that the meta-data of Web Dynpro Java is saved as XML and
that Web-Dynpro Java Runtime generates runnable classes and sourcecode out of this...
- What about Web-Dynpro ABAP? Is Meta-code in ABAP is saved in XML too?
- just for theory: is ist possible to take the meta-data of a Web-Dynpro ABAP component and
generate a Web-Dynpro Java Component out of this?
I tried to find it out but i failed... In table WDR_RR_LOAD (is this the right one?) I found only the
field data. But this is a RAWSTRING and I don´t know how to make I "readable".
I must know this for my thesis for my studies, not for work.
Thank you very much !!!!
Greetings,
Oliver

Me again,
I am not sure if I understood it right...
The meta-data which describes the visual part of a view is saved as XML and
would be rendered i.e. in the webbrowser... Right?
What about the meta-data of the Web Dynpro application?
Is this meta-code into an other structure or XML too?
Thank you very much.
Many Greetings,
Oliver

A question on component design in Web Dynpro

Hi experts,
We currently working on our console which we want to implement them using Web Dynpro framework.
During design time, questions have been raised: we have like 100 EJB methods for our application, about 8 EJBs, we want to have faceless component taking care of persistence.
The question is what is the best way to distribute the methods in terms of performance and supportability (for ease of development )? We discussed the following options:
1.     One faceless component with one component controller implements 100 methods (maybe this is the worst)
2.     Many faceless components, one for each EJB, here the question came up: performance because we have a tab strip in the UI that accesses 6 EJBs, would it take a long time to load/unload these components every single time we switch among the tabs ?
3.     One faceless component with one custom controller for each EJB, here the question is: can we expose the custom controller in other to use them in the tabs? Compared to option 1 we clearly separated the methods, so it is easier to support. Furthermore we should have a performance gain since the custom controllers are only loaded on demand.
What do you think?
Regards,
Dat
Edited by: Dat Triet Banh on Jul 4, 2011 4:47 AM

Hi
Better to segregate the EJB's and put it in seperate controller keep atmost 30 in one controller (you have around 3-4 component ). Any component which is going to use in other component is basically based on create on demand priniciple automatically by framework.
or
as given in point third create a component , with say 8-10 Custom Controller implement the all the methods and put a same method signature in Component Controller, call the same through interface thats it.

Error when importing an old web dynpro project

Hi all,
I've have upgraded my Sap Netweaver Developer Studio from 2.0.13 to 7.0 .
Now when i try to compile my old WD project it returs the seguent errors:
1)The project was not built since its classpath is incomplete. Cannot find the class file for java.lang.Object. Fix the classpath then try rebuilding this project
2)This compilation unit indirectly references the missing type java.lang.Object (typically some required class file is referencing a type outside the classpath) PackagePointer.java Project/gen_ddic/datatypes/com/sap/function/model/types line 1
Where can i find the java.lang.Object?
thanks, Daniele

Hi all,
maybe is too late.. but I wish to share my humble experience with you.
I encounter in a similar problem...
When I'm working with Web Dynpro (Messagge Pool) suddenly the NWDS seems to be crazy and give me the error "this compilation unit indirectly references the missing type java.lang.Object "
I read many post, this one too, but still got the problem.
Compare the current WD project with another one I found that my project didn't have rt.jar ibrary in its library list.
So I add in WD project - properties - Java build Path - Libraries the rt.jar library.
In my case it was in C:\j2sdk_dir\jre\lib\rt.jar.
So I build project and the problem desappear.
I hope this experience will be usefull.

When I test the web dynpro page, the browser does not display it !

Hi all,
I have (SAP EHP 2 for SAP NetWeaver 7.0) trial version installed in my laptop. Lately, I took course NET310 about web dynpro. I started doing the exercises but when I test my work, the browser (Internet Explorer 8) does not display the page I created but it displays a page has the following message (Internet Explorer cannot display the webpage). When I installed the SAP, one of the requirements was (Domain), so I entered one but the one I entered does not exist. If this is the issue, then I have to create a domain with the same name but how can I do this in my laptop? (my laptop has Windows 7)

Hi Anil
the page shows the following:

Another image question - using Regular ABAP not web dynpro

Following Otto's awesome instructions:
1) create image field in your form (not only image!! it must be the image field)
2) load your picture in the backend
3) convert the image into XSTRING
4) create the XSTRING variable in the interface/ context, fill it with the picture data
5) bind the image field to this variable
6) enjoy
Regards, Otto
We can easily get an image to appear on a form produced from Web Dynpro ABAP using an XML interface.
However, we are having an issue doing the same using a regular ABAP report and Data Dictionary interface.
We added a new field to our DDIC structure called signature TYPE RAWSTRING (we can't define a new domain with type X since SAP doesn't allow that, but they are both Variable Length Byte Strings).
We use the exact same code to upload the same image from UNIX, we see the byte string in our variable, but no image appears on our form (using the ImageField object).
We then created a Global variable with type Xstring in our interface. We pass our binary image to the function module. Through debugging, I see that an error occurs because the gloabl variable states it's max characters is only 255.
any ideas?

Otto,
thanks for the replies.
I did make sure to embed the image. We tried both jpg and bmp, but neither worked.
for testing, I hardcoded this in the WD and it worked. I copied it over to our ABAP method
DATA: lv_ds TYPE string VALUE '/sapmnt/DEV/interface/renewables/pbch-1/archive/352.bmp',
             lv_xstring TYPE xstring.
OPEN DATASET lv_ds FOR INPUT IN BINARY MODE .
CHECK sy-subrc = 0.
DO 1 times.
    READ DATASET lv_ds INTO lv_xstring.
    IF sy-subrc <> 0.
      EXIT.
    ENDIF.
ENDDO.
This gets me an Xstring field that's 1272 long.
I pass the lv_xstring field directly to the FM IMAGE field, which is defined as an Xstring in the PDF Interface
CALL FUNCTION ls_function
    EXPORTING
      /1bcdwb/docparams = fp_docparams
      is_scale_stng      = ls_scale_stng
      it_scale_tkti      = it_scale_tkti
      it_scale_seal      = it_scale_seal
      is_scale_tkt       = ls_scale_tkt_print
      image              = lv_xstring          " <---- pass the xstring image
    IMPORTING
      /1bcdwb/formoutput = ls_form_output
    EXCEPTIONS
      usage_error        = 1
      system_error       = 2
      internal_error     = 3
      OTHERS             = 4.
Stepping into the FM, I see that IMAGE now has the same size of 1272
In my PDF Form layout, I dragged/dropped the ImageField object on my form.
I found the IMAGE field in my Data View tab and dragged/dropped that onto the ImageField to Bind it.
I checked 'embed image data'.
I checked the form properties and the layout was set to 'Standard'. I changed it to ZCI, as well.
I know the data is coming across because I can drag/drop the image field from the Data View directly on the form as a Text Field and see the hex data come through.

Error message when I run the Web Dynpro Project

Dear friend,
I had deploy & run project, but it's got the error message under the line:
I had install NWDS V. 2.0.11 on my PC, but the project which I deployed was the version that I created by NWDS V. 2.0.9, and I had install new OS as XP Home instead the old one (Windows2000), are these the cause of problem?
Please advise how can I do.

Probably the usual problem of deploying an application built with a newer NWDS (SP11) on an older server (SP9).
But without the stacktrace this is only a guess.

GP + Web Dynpro (Interface o Application)+ Web Services

Hi,
I have a scenario, in which I require to create a web dynpro, which will be utilized in a Callable Object, inside GP. This web dynpro will be like a form, which will be fed from 2 sources.
An external Web Service, that brings information from a website, spefically from a catalog.
Information filled by the user, in the fields of the form.
In short, the form is composed of information supplied by a Web Service and information completed by the user.
I would like to know if is possible to create a web dynpro, in NWDP, in order to be included in a Callable Object, inside a Worklfow in GP.
Regards.

Hi David,
yes, it is possible, you can create the callable object for the webdynpro and you put it into GP work flow..

ABAP Web Dynpro isolation method

Hello all!
i have a scenario where i need to publish a ABAP Web Dynpro app to my outward facing portal. the issue is that i am using reverse proxy which allows me to secure the external portal..
When i create an ABAP WD Iview i am forced to have the isolation to URL which makes a separate call from the browser to the ABAP system for the content. I need to be able to render this on the server in more of an embedded style so the calls continue to go through the reverse proxy.
Any thoughts would be appreciated.
Regards,
Joe Villar

Pre,Post,OverWrite Exit for web dynpro ABAP methods of component,view

Hi,
my question is i have created overwrite exit for method of component controller in one enhancement implementaion say ENH1, and i also created overwrite exit for same method in another enhancement implemenation say ENH2, it means i have two different implemenations now,
My questions here is, will both Enhancement implemenations will "execute", if yes in what order..
Please clarify.
Thanks.

I'm afraid the information that Manas gave you is incorrect. In an overwrite method, the enhancement completely overrides and replaces the original method. Both versions are NOT executed. This is the risk you run with the Overwrite enhancement - you are choosing to completely replace the SAP delivered logic.
From the Online Help:
The overwrite exit method takes on the signature of the original method and overwrites it. This means that an overwrite exit is executed instead of the original method.
At runtime only one overwrite exit can be active. If several overwrite exits are active, a runtime error occurs.

Web dynpro Interface context mapping

Hi All.
I shall tell my problem with a very simple scenario that anybody could implement in 2 min.
Webdynpro Interface component -> Z_INTER; context node: ORDER_VALUES, cardinality 0..n; table: VBAK, select VBELN.
That's it.
Now, Webdynpro component : Z_COMP -> Used component -> Z_INTER.
Inside component controller, I declare usage of Z_INTER. Then do a direct mapping of ORDER_VALUES from Z_INTER to Z_COMP.
So the context node ORDER_VALUES is created in the Z_COMP component controller.
That's it.
Inside WDDOINIT() method of comp controller, read the context node's attribute VBELN.
The line:
elem_order_values = node_order_values->get_element( ).
gives a dump saying that:
The following error text was processed in the system : Error when Creating Component Z_INTER. Z_INTER Is a Component Interface, Therefore, an Instance Cannot Be Created. Name of Component May Not Be Specified. (Used Component: Z_COMP, Component Usage: USAGE1)
Can anybody guide me how do we map interface context? I guess I am not getting the concept and am doing some fundamental mistake.
Thanks !

Hi Aishi,
When you use a component interface, you cannot declare it as a component usage. You need to add it under 'Implemented interfaces' and say 'reimplement'. If you want an interface node mapping between 2 components, then you have to declare a normal component. Specify the node as an 'interface node', which means it is visible to components using this component. And then do the mapping.
