Map context node web dynpro to context DATA of interface controller ALV

Hi Experts,
I have started creating simple ALV by following the example in the below mentioned link.
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/3439404a-0801-0010-dda5-8c14514d690d
I have completed 95% development but stuck with last bit of
Set data to ALV for display (via reverse context mapping).
When Click on the Controller Usage button. The component controller of your Web Dynpro component DOES NOT appears on the right side of the screen.
Therefore I can not Map context node NODE_FLIGHTTAB of your Web Dynpro component to context DATA of the interface controller of the ALV component.
Could you please shed me light on this.
Your time and help much appreciated.
Best Regards
CB

Hi Chandra,
You need to add component controller first. Just go to the property tab of interface controller of the alv component and click on create button and then add the component controller. After that you'll be able to see the node in the context tab.

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.

Retrieve data from other context node within the same context

Hi Experts,
I want to redefine method BUILD_TABLE for a table context node and I need to access data from another context node within the same context. I have looked through the methods of class CL_BSP_WD_CONTEXT_NODE_TV but could not find a mean of retrieving the other context nodes.
Any ideas?
Thanks a lot. Your help is appreciated.
Cheers,

How to mapping Bapi_EeCatimesheet with Web Dynpro iview

I have problem with CATS:
1. mapping field from Web Dynpro iview with Bapi_EeCatimesheet_Worklist
Column: Activity = Bapi_EeCatimesheet_Worklist_input_Out.???
Column: xxx = ???
Variable as TimeSheet of SAP Easy View
2. How to insert Employee timesheet into SAP System by Bapi

Hi,
At first time the ApplicationParameter was not displayed among the mappable properties. After that I changed the ApplicationParameter property of the WD iView (so it became different from the default one) and created a new room template. What happened ? At the new template I could map to room_id to the ApplicationParameter. Interesting, not?
One other thing: What do you think about the following ?
1. First creating a "Concat Strings" extension to create a string like "room_id=<room_id>"
2. Creating an other extension and mapping the newly created string to the ApplicationParameter property
3. Getting the parameter from WD with the help of getRequestParameter(java.lang.String key)
I have not tried it yet, but I plan to do it.

How to map XML to Web Dynpro context nodes?

Hi All,
Could anyone tell how xml string can be bound to context nodes ? In my requirement i need to serialize context nodes value to string and deserialize it back to nodes for implementing back naviagtion between views.
I didnt see much threads achieving this giving details on class cl_wdr_xml_convert_util and methods if_wd_client_conversion_util~string_to_struct.
I am using wd_context->to_xml to convert into xml.
From this format, i want to bind it back to context node.
When i use this below approch i get short dumb.
Serialization to xml:
lv_data_string = wd_context->to_xml( ).
Deserialization:
DATA lv_typedescr           TYPE REF TO cl_abap_typedescr.
FIELD-SYMBOLS:
                 <fs_data>    TYPE ANY TABLE.
CALL METHOD cl_abap_typedescr=>describe_by_object_ref
    EXPORTING
      p_object_ref         = wd_context
    RECEIVING
      p_descr_ref          = lv_typedescr
    EXCEPTIONS
      reference_is_initial = 1
      OTHERS               = 2.
   try.
CALL METHOD cl_wdr_xml_convert_util=>if_wd_client_conversion_util~string_to_struct
    EXPORTING
      in            = lv_data_string
      typedescr = lv_typedescr
    IMPORTING
      data      = <fs_data>
CATCH cx_wdr_conversion_exception into lo_err .
lv_exp = lo_err->get_text( ).
ENDTRY.
wd_context->bind_table( values = <fs-data>.
Using this way, i get a short dumb as assert statement is failed as value for typedescr->type_kind is '*'.
method if_wd_client_conversion_util~string_to_struct.
assert typedescr->type_kind = cl_abap_typedescr=>typekind_struct1
      or typedescr->type_kind = cl_abap_typedescr=>typekind_struct2.
raise exception type cx_wdr_conversion_exception
    exporting textid = cx_wdr_conversion_exception=>illegal_type.
On debugging changing this value to required also made no difference, as no value could be assigned to the field symbol.
Suggest a soution to do this.

Hi Thomas,
Thanks for your replies.
I have corrected it, but the field symbol is empty and while debugging it says data type is incorrect.
code:
FIELD-SYMBOLS:
                 <fs_data>    TYPE ANY TABLE.
data:       lsbp type ZXBPCENTRAL,
               go_ref type ref to data.
CALL METHOD cl_abap_typedescr=>describe_by_data " ( before it was describe_by_object_ref)
EXPORTING
p_data = lsbp
receiving
p_descr_ref = lv_typedescr.
try.
CALL METHOD cl_wdr_xml_convert_util=>if_wd_client_conversion_util~string_to_struct
EXPORTING
in = lv_data_string
typedescr = lv_typedescr
IMPORTING
data = go_ref "<fs_data>
CATCH cx_wdr_conversion_exception into lo_err .
lv_exp = lo_err->get_text( ).------> Here the error says " Invalid data type and hence, there is no data.
ENDTRY.
assign go_ref->* to <fs_data>.
I am still looking for solution and thanks a lot ....

How to get Portal User Context in Web Dynpro application

I have successfully integrate a web dynpro app into SAP Netweaver Portal.
Within my web dynpro app, how can I get portal user context information such as first name, last name, job title or some newly created ume attibutes.
Is there any programmatical approach to get portal user context in my web dynpro. I not sure whether I can use the following codes in web dynpro?
IUserContext userContext = request.getUser();
String firstName = userContext.getFirstName();
String lastName = userContext.getLastName();
If yes, can someone point me the name of the jar file I have to import.
Note : The SAP Netweaver installation that runs my web dynpro app is same with the SAP Portal.

Hi ,
you can use the below code to get User details and add com.sap.security_2.0.0 > lib > com.sap.security.api.jar
try
IWDClientUser clientUser = WDClientUser.getCurrentUser();
String firstName = clientUser.getFirstName();
String lastname = clientUser.getLastName();
catch (WDUMException e) {
wdComponentAPI.getMessageManager().reportException("Error Retrieving User"+e.toString(),true);

Mapping one node in a view context to many nodes in the component controlle

Hi guys,
I need to map an element (attribute) of a node in the View Context to an attribute of multi nodes of the same type:
Context View:
customer_no
      |
      | -> KUNNR
Component Controller Context having two nodes:
- Node1
     RFC1
        |
        |->KUNNR
- Node2
      RFC2
         |
         |->KUNNR
Above I need to map the (KUNNR) in customer_no node to KUNNR in the RFC1 RFC2 before i execute the two RFCs services.
Note:
if this is not possible would you mention another solution.
Thanks,

Hi,
   As per MVC you cannot map context from view controller to component controller.Mapping can happen from component
controller to view controller.
You cannot create mapping for context attributes. You can map nodes if both source node and destination node both has same structure and same number of attributes. If they dont contain same number of attributes the extra attributes from the source node gets copied to the destination node.
In your case before the RFC execution you can read the value of attribute Kunnr from view and set it the RFC attribute Kunnr before the Function module execution.

         comp_controller type cl_bsp_wd_component_controller.
lr_comp ?= me->comp_controller.
IF lr_comp IS BOUND.
    TRY.
lr_entity ?= lr_comp->ZTYPED_CONTEXT->ZBTCUSTOMERH->collection_wrapper->get_current( ).
     lv_ref_guid = lr_entity->get_property_as_string( iv_attr_name = 'REF_GUID' ).

Clearing Context in Web Dynpro applications

Hi All,
I am using a view that is called from multiple places based on different criteria. This view has a table that is fed from the custom controller. Some of the context data for this custom controller are being set from the other views. I need to clear the resultset of the custom controller and retain the input data from the other views. Is there any simple way of clearing data in the context node? I tried invalidating the node, context but nothing seems to work. Any suggestion what I might be doing wrong?
Thanks and regards,
Hemanth

hi Hemanth,
Where are u trying to invalidate the node. What is the exact scenario.If u want the custom controller to be updated in different views... u can say
wdThis.wdGet<contr name>Controller().wdGetContext().node<name>().invalidate();
in the init of the view where the value of the custom controller is updated.
Is the problem with invalidate or with the updation in values.Invalidate will always work if u set the lead selection properly.
If u cud elobarate more on the problem someone could really help u out...
Regards

Clear context in Web Dynpro

Hi,
I have created a table based on search crieteria.
The scenario is first time e.g user has given some selection, it will return 5 records. These 5 records will be displayed in the table.
Now, if user enter some selection, which does not return any record, in that case i'm displaying the error message.
For displaying the message, i'm using get_element_count method, if it's > 0, then it displays the table else display the error message. But the problem is even in second time, if there is no record return, get_element_count mehtod return 5 records of the first search.
How to clear the context, or how to proceed. I can change my condition for a temp solution, but pls let me know what is the best way to do this.
Thanks,

Google Map route in web dynpro question

Hi all,
     I have a route from add_A to add_B in my database, i want to get this route data from database and show up in google map page. The show up function can be implement by call google map javascript. My problem is how can send route data from web dynpro to my google map page. The google map page can be a JSP or html page, assume that we use the iFrame element to show this page.
    I search forum, there is a way send the data by url parameter, but my case, the route data should be very large, may not be send by the url parameter. If any one have good idea or other solution for my case.

Google maps url in Web dynpro for java

Hi all,
Can someone tell how I can create a Google Url and show this Url in a Iframe in a Web dynpro. I can create an url but I see the google webpage with the map. I just want only see the map in my Iframe!
Kind Regards,
Richard

Hi Richard,
One solution that comes to mind is to have a URL parameter embedded. So the path that you have set to the iframe can be extended say for example http://<your path to HTML file in Mimes>?undefined=<address specific to the user>
Next thing to do is extract the URL parameter undefined by JavaScripting. So you can pass the address value to this param.
Once you have this you can trigger this by passing different addresses to URL parameter each time.
Replace the wdDoInit() by following code:
public void wdDoInit()
    //@@begin wdDoInit()
     try {
          String resourcePath = WDURLGenerator.getWebResourceURL(wdComponentAPI.getDeployableObjectPart(), "GoogleMapAPI.html");
          wdThis.wdGetContext().currentContextElement().setPath(resourcePath + "?undefined=Mumbai");
     } catch (WDURLException e) {
     wdThis.wdGetAPI().getComponent().getMessageManager().reportException(e.getMessage(),true);
     } catch (WDRuntimeException e) {
          wdThis.wdGetAPI().getComponent().getMessageManager().reportException(e.getMessage(),true);
    //@@end
Though I have hardcoded the location in above URL, i guess you got what i am indicating at!!
Even after all this, be carefull in preparing the URL which might result invalid URL due to special chars.
For Example: New York will result in invalid URL as <space> is not allowed. Ideally, it would have been New%20York. But then google API will no understand %20. Hence, I recommend you to replace %20 by <space> before calling Google API [You will have to write it in initialize() method of HTML file].
Also, replace the function initialise() in GoogleMapAPI.html
function initialize() {
      if (GBrowserIsCompatible()) {
        // This function is anonymous, is executed immediately and
      var query_string = {};
        var query = window.location.search.substring(1);
        var vars = query.split("&");
        for (var i=0;i<vars.length;i++) {
          var pair = vars<i>.split("=");
          // If first entry with this name
          if (typeof query_string[pair[0]] === "undefined") {
            query_string[pair[0]] = pair[1];
            //this.address.value = pair[1];
             map = new GMap2(document.getElementById("map_canvas"));
             geocoder = new GClientGeocoder();
             showAddress(pair[1]);
I hope your address issue is addressed by me now!!

Web Dynpro for Accepting Data Changes

Hi,
I have a requirement where I need to give a screen with the fields of
| Customer|.Material | Enduser | Market | Market Segment | . Customer & Enduser is Compounter to Material. and Maket & Market Segment are Attribute of Material Master( Z Object).
We are using these objects in COPA Cube. Market & Market Segment are NA. There are millions of records in Customer / Material /End user combination. But there is no data maintained for Market & Market Segment.
We want to maintain where there is any sale happend for Customer Material and Enduser combination.
I created a Query to filtered the record with sales fall in this period with out market & Market segment. And used APD to updated it to DSO.
Now i want it to present to User to enter the data in the Market & Market Seg fields for the Material/Customer/Enduser combination.
Please let me know your thoughts on this. We are trying to build a WEB DYNPRO for this. But will a Dynpro will accept the data and change/update it in the backend table ?
Points are sure for proper guidance.
Thanks.

In terms of Complexity .. I would rate the following in this order :
1. BSP
2. WDA
3. WDJ / VC
(* I have not worked in WDA and hence this ranking )
In terms of Presentability :
1. VC
2. WDA / WDJ
3. BSP
The main reason being that BSP renders in Plain HTML and you can make the BSP interesting and more presentable using Embedded flash objects / HTMLB etc ... I am referring to plain BSP Pages .
The rendering options are much better in WDA and VC would give you a better front end ... but then VC does not lend itself into a User Entry tool - bbut more of a reporting / display tool....
You can use BSP and formatting options not withstanding - you can just create a WDA with Flash Islands .... to make the most of both worlds...
I am not sure if this is simple in VC - you might have to get into the JCO conections etc for making the field editable. WDA with flash islands is much more manageable but then forthis you need to be in EHP1...
