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.

Calling a method in the view controller from the component controller

Hi
Is there anyway to call a method in the view implementation from the component controller??
Thanks
jack

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's VIEW gets triggered
3. and THEN the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering LoadData() of the COmponent COntroller from the wdDoInit of the VIEW.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks
Jack

Call component controller method from view

Hi
I have created an action in view Thus its event handler is "OnActionDoSomething()"
And, I have a method in component controller "MethodSaySomething()".
Now, how can I call MethodSaySomething() from OnActionDoSomething().
OnActionDoSomething()
// Call MethodSaySomething() defined in component controller
Thanks

Hi,
To access the methods present in component controller from View , first u need to add the component controller as the required controller.
open the view controller --> switch to propertues tab --> add the component controller as required controller(click add controller).
Now in your action handler , write this below code to add the method:
wdThis.wdGet<COmponent Controller>().MethodSaySomething();
Hope it helps
Thanks and Regards,

Read a View Context's node's element and assign from Component controller

Hello Experts,
I'm new to JAVA WD.
Here is my scenario.
I have to use an Adobe form in a WDJ. The input parameters and the output parameters of the DC are defined in a method in the Interface Controller method.
The context of the Component Controller has the following structure
Context
---StartDate
---EndDate
---AbsenceType
Then the mapping between the Component controller and the interface controller is done so that the Interface controller also has the context structure as
Context
---StartDate
---EndDate
---AbsenceType
So now the interface controller and the component controller are bounded correctly.
Now I bind the view also with the Component controller as below.
Context
---StartDate
---EndDate
---AbsenceType
But since i need to use an Adobe interactive form inside this view, the datasource for the form cannot be the root context node but some other node. So I replicated the same structure in the view context so as to make the fields visible in the Adobe form context. Now the context looks as below.
Context
---StartDate
---EndDate
---AbsenceType
---DATA_NODE
-----StartDate
-----EndDate
-----AbsenceType
Now my question is, how do i map the result from the Adobe form into the context of the view??
What code should i write and where should i write to achieve this?
I need to do the following. But dont know how to write the code for this.
Context.StartDate = Context.DATA_NODE.StartDate
Context.EndDate = Context.DATA_NODE.StartDate
Context.AbsenceType= Context.DATA_NODE.AbsenceType
Please help!
Any help will be greatly appreciated.
Thanks,
Sam

Hello Nikhil,
I'm stuck with another small issue.
Let me first explain what I'm trying to do.
I have a view with the context structure as follows
Context
---DATA_NODE (Node)
----Data1
----Data2
---Data1
---Data2
All i need to do is, at the start of the view, i need to move the data from
Context.Data1=>Context.DATA_NODE.Data1 and
Context.Data2=>Context.DATA_NODE.Data2
Also, at the View Submit button click, I need to move the data from
Context.DATA_NODE.Data1 => Context.Data1 and
Context.DATA_NODE.Data2 => Context.Data2
(I managed to do this submit button click by calling an action->method and wrote the code as you gave earlier)
wdContext.currentContextElement().setData1(wdContext.currentData_NodeElement().getData1());
wdContext.currentContextElement().setData2(wdContext.currentData_NodeElement().getData2());
But I wrote at wdInit() for the view the code in the reverse way, but the values are not getting passed to the Data_Node and hence its not defaulting with the values from the elements of the context.
This is what I wrote.
wdContext.currentData_NodeElement().setData1(wdContext.currentContextElement().getData1());
wdContext.currentData_NodeElement().setData2(wdContext.currentContextElement().getData2());
Please let me know if I'm doing something wrong here.
Appreciate your help in advance!
Cheers,

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.

Map node from different View Container

hi all,
i have a question about WDA. In case i have 3 view controllers: V_MAIN, V_A, and V_B. This program lets the user to fill out the form on V_A and V_B. V_MAIN has view containers embedded by V_A and V_B.
If i want an application to submit the form by click the Submit button on V_MAIN. The button has an action to send the parameters which fetch from V_A and V_B to do something further.
I've tried to declare the variable by
data: lr_v_a type if_v_a=>element_node.
the system shows an error "The type if_v_a=>element_node. is unknown"
Do you guys have any ideas about this? Please share me then.
Hope you can figure out what I'm saying. Thanks in advance.
Peerasit

Hi...
Use Global Component controller for all the view your using.... so that any time if you want data.... you can access it from the component controller...... try to use always global........
so if you click submit and want to do something further..... you can get the values from component controller and pass it to the next process..... its simple.....
Hope this will help you.....
Thanks & regards

Mapping between view controller and component controller

Hi Experts,
I am new to web dynpro ABAP. First I created an application using one input field and one button, my view name is V1. In view context, I created one node viz. NODE1 using table SFLIGHT, fields chosen are CARRID CONNID and FLDATE. I have bind that to my input field and for button I have not done any thing. So, when I am running this application it is allowing me to select value for my input field. After this, I have added a table to the view layout. I have added to nodes using sflight table in COMPONENT CONTROLLER. First node is SFLIGHT with CARRID, CONNID, FLDATE, PRICE and PLANETYPE and second node is NODE1(same name) with only CARRID. Now in VIEW CONTEXT it is showing -
CONTEXT
 NODE1
 CARRID
 CONNID
 FLDATE
(which I had created in VIEW CONTEXT for input field)
CONTEXT COMPONENT CONTROLLER
 SFLIGHT
 CARRID
 CONNID
 FLDATE
 PRICE
 PLANETYPE
 NODE1
 CARRID
(which I had created in component controller after adding table)
Now both this context should be matched as per my knowledge, so that when I bind the table it should V1.SFLIGHT.<fieldname> and not as V1.NODE1.<fieldname>
But I don't know how to match them. Please help.

Hi Sambaran,
I guess I understood what you want.
To achieve this, proceed as follows:
1)Open your View, goto Properties tab. Here in the Used controller table, click on the create icon to include the component controller (component controller is added by default by the framework, if you use custom controller you need to define this usage).
2)Once you do this, goto Context tab of the view, here now you will be able to see the component controller on the right hand side.
3)Next, drag the SFLIGHT node from the component controller, and drop it on the Context (root context) of the view (left side). Doing this system will create a mapped context node on the view which you will use to bind to the view elements on the layout.
The above steps apply if you want to directly create a view context from component controller context.
Hope this helps!
Thanks,

How to populate context node of component controller

Dear People,
Is there any way i could access my custom context node of component controller in the context node class of my custom controller.
I am navigating from one component to another, Upon initial launch everything is working fine, however if i go to home page and come back. the assignment block is coming empty.
In WD_USAGE_INITIALIZE i m binding my custom controllers context node with the component controller's context node of the other component and it works fine when i load the UI. however if i go to home page and come back. the assignment block is coming empty.
Following code is in method of DO_VIEW_INIT_ON_ACTIVATION of the other componenet.
METHOD do_view_init_on_activation.
DATA:   lv_btstatus_parent TYPE REF TO cl_crm_bol_entity,
        lv_comp_ctrl      TYPE REF TO cl_btstatus_bspwdcomponen_impl.
CONSTANTS:
        lc_us_header      TYPE crmt_relation_name VALUE 'BTStatusHUserAll',
        lc_us_item        TYPE crmt_relation_name VALUE 'BTStatusIUserAll'.
lv_comp_ctrl ?= me->comp_controller.
check if relationname has been passed from outside
    gc_relation_name = lv_comp_ctrl->get_relation_name( ).
IF gc_relation_name IS INITIAL.
check type of parent to determine relationname
    *lv_btstatus_parent ?= lv_comp_ctrl->typed_context->btstatusparent->collection_wrapper->get_current( ).*
   check lv_btstatus_parent is bound.
    CASE lv_btstatus_parent->get_name( ).
        WHEN 'BTStatusH'.
          gc_relation_name = lc_us_header.
        WHEN 'BTStatusI'.
          gc_relation_name = lc_us_item.
    ENDCASE.
ENDIF.
CALL METHOD super->do_view_init_on_activation.
ENDMETHOD.
Here lv_btstatus_parent is bound during initial launch, however after navigating back to the same page, its blank leading to exception.
any suggestions would be helpful.

How to access View Context thr' View Controller; and not thr' View....

Hi
As we know that we can access Component Context Attribute by Component Controller in view as:
wdThis.wdGet<Component_Name>Controller().wdGetContext().currentContextElement().
get<Component_Context_Attribute>
whereas wdThis.wdGet<Component_Name>Controller() is the Component Controller.
So, in the same way, I was just wondering do we have any way to access the View Context through View Controller.
Generally for view context, we use wdContext which is (= wdThis.wdGetContext() ) means accessing view context thr' view.
i want to access View context thr' View Controller which is wdThis.wdGetAPI().
Thanks....

Diff between Component controller,Custome controller and View controller

hi,
Can any body tell me the following details,
1.difference between the Component controller,Custome controller and View controller in WD-ABAP.?
2.what is Lead Selection?
Regards,
Ravi

Hi Ravi.
The component controller is visbile to all views in a component. So all context nodes and methods you create here can be accessed from all views in the component. This way you can share data between the views by mapping context nodes or thru method calls. You can also mark methods and nodes as interface so that they are acessable from other components that define component usages to this cmponent.
Custom controller is quiet similar to the component controller. You can define it if you want to group some views with a custom controller for a certain functionality.
If you want to access a custom controller in a view you have to define the usage first on the properties tab of the view.
A view controller is only visible in the view itself. So all methods or context nodes you define here are only accesable by the current view.
The lead selection is in most cases the current selected element in a context node. The lead selection is used by many UI elements to determine which element has to be shown (e.g drop down).
If you have a table with single selection the current selected table row is the lead selection element of the bound context node.
SO you can get the lead selection element easily in any mthod by calling context_node->get_element( ).
Hope this clears your questions.
Cheers,
Sascha

Calling RFC from view/component controller

I've got a model node in the component controller's context which is mapped to a node in a view controller. Now, when binding the model's input node with an array and executing the RFC from within an event handler in the view controller, everything goes just fine.
Now, I want to put this functionality in the component controller, so I created a method there, copied the code and call it from the view controller's event handler. When the RFC is called, the input table always contains just 1 element, of which the fields are all initial.
Any thoughts on what might be going on here?

Hi friend,
I too faced the problem what you faced.
Near to it.
Ill explain you .
YOu have your model node.
1st you will map that to component controller And from there to view controller.
After that you will bind the elements in this node to some elements in your view after that .
For example
Model class name:-Lok_model.
In the DOINIT method:-
write this code.
Lok_model k = new Lok_model(); wdContext.nodeLok_model().bind(k);
Suppose you have a button in the onaction you write this code.
wdContext.nodeLok_model().currentLok_modelElement().modelObject().get_details();
Ill expalin you about this statement Lok_model() is the node in my view which is mapped from the model and by using that i am calling the method get_details() which is in my model class Lok_model.By this data will be automatically populated into the view elements which are being binded to the model attributes.
Hope this helps you,
Lokesh

How to fire event in view controller from component controller.

I have a component usage that fires an event wich i have subscribed in the component controller.
iv_usage->subscribe_event( iv_event_name = 'TAKE_IT'
iv_handler = me ).
After the event the method IF_BSP_WD_EVENT_HANDLER~HANDLE_EVENT in the component controller is called.
method if_bsp_wd_event_handler~handle_event.
endmethod.
The usage component is opened as a popup window. After pressing a button, the data is transfered via context node binding to the calling component. But now i want to close the popup.
My intension is to fire a event for the view controller in the IF_BSP_WD_EVENT_HANDLER~HANDLE_EVENT method that closes the popup.
Is this possible?
Or let me explain it this way:
I want to close a popup after a button in the popup is pressed.
best regards
Jürgen

Hello Juergen
I am assuming your target pop-up is of type ref to IF_BSP_WD_POPUP.
1.Make this a view controller class attribute.
2. After the code to create the pop-up, you can add the following block :
gv_target_popup->set_on_close_event( iv_view = me iv_event_name = 'CLOSEPOPUP').
3. Now define event handler EH_ONCLOSEPOPUP where you can write the logic for on_close.
You can access the same reference gv_target_popup at the event handler level as well.
Hope this helps.

How to call Custom or Component Controller methods from View Controller

Hy Guys,
how do I call Custom Controller or Component controller methods from a View or Context Controlller?
thanks in advance
Jürgen

Hi Juergen
Yes it is possible, pls follow the below approach to access the component controller in context node class
1) since the standard component controller class is protect variable , declare a variable of type component controller in your controller class.
say for example the public variable you declared is g_comp_controller
2) now redefine the controller class method WD_CREATE_CONTEXT and add the below lines of code
   g_comp_controller ?= me->comp_controller.
3) go to context node class (CNXX) there declare the varaible which of type controller class (IMPL) as public variable, for example g_owner
4) redefine the method IF_BSP_MODEL~INIT and write the below code
     CALL METHOD super->if_bsp_model~init
    EXPORTING
      id    = id
      owner = owner.
g_owner ?= owner.
5) now the variable   g_owner that is declared in (CNXX)   contains reference to your controller class
6) in on_new_focus method access your component controller in the below manner and access the entities also.
DATA: lv_owner                    TYPE REF TO xxxxx_impl, " Implementation class
             lr_comp_cont                TYPE REF TO xxxx_bspwdcomponen_impl, " component controller class
             lv_entity type ref to cl_crm_bol_entity.
lv_owner ?= g_owner.
lr_comp_cont    ?= lv_owner->g_comp_controller.
IF lr_comp_cont IS BOUND.
   lv_entity ?= lr_comp_cont->typed_context->mdfcampaign->collection_wrapper->get_current( ).
now lv_entity contains the value of component controller context node.
Thanks & Regards
