Instantiating Model Node in Component Controller with new Abstractlist()

Hi All,
We have the following issue.
When we instantiate a Node - Po_Items using Element.setPo_Items( new AbstractList() )
We get an error "The Type AbstractList Cannot be instantiate" .
So how to successfully instantiate AbstractList() so that ultimately the BAPI_NODE_INPUT can be instantiated.
Best Regards,
Roby...

Hi Murtuza,
Thanks alot for the response.
I tried initializing Node using
Element.addPo_Items(new Bapiekpoc());
But its not getting initialized and I get following errror when I run the application.
500 Internal Server Error
Web Dynpro Container/SAP J2EE Engine/6.40
Failed to process request. Please contact your system administrator
Is there any other way to initialize the Po_Items Node which which is inside the Model Node BAPI_PO_CREATE_INPUT.
BAPI_PO_CREATE_INPUT ( Model Node )
-- Po_Items ( Subnode which is an input table inside the BAPI )
Thanks again & Best Regards,
Roby....

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.

Looking for expert who can highlight 3d model node in adobe reader with external program

I need to select and highlight 3d model node in adobe reader with my program.from outside of adobe reader. it seems there is no out-of-box API in stndard SDK. I want to outsource this task fully or partly. If you have the solution or able to provide consultant in this area, please send message to me.

You would indeed need a plug-in to actually select and highlight but you can easily call attention to a part by temporarily changing the color via JavaScript which you can access from external applications.
I can provide more specific advice if you explain the exact user interaction you're looking for. Is this a desktop application? Is the PDF in a browser? etc.

Need to bind value attributes of Component controller with value attributes

Hi,
I am developing a Java Web Dynpro application which is importing RFC Model.

Hi Kaushik,
It is very simple to enter values in webdynpro and to update the ztable through RFC
All you hav to do is
1. Create the ztable , RFC to import data into that table,
2. Create the model in webdynpro with that RFC
3. First map the ModelInputElements to the component controller(say zid, zname) (you can have your own value attribute in component controller say id , name )
4. Map the attributes to the view where the input field is there
5. Now write the code as follows,
Zxxx in = new Zxxx();
wdContext.nodeZxx_InputElement.bind(in);
in.setZid(wdcontext.currentContextElement().getId()); // getId component controllers attribute and getZid is model' s mapped attributre
in.setZname(wdcontext.currentContextElement().getName()); // getName component controllers attribute and getZname is model's mapped attributre
/* u need not have to map that model attrobute to component attribute for that */
try
in.execute();
Catch(Eception e)
e.printStackTrace();

External component usage with interface node

Hi everyone,
I have component A , which has an interface node with Input element checked:
Nodes
Node Name     IF_HROBJID
Interface Node     1
Input Element (Ext.)     1
Dictionary structure     ZHR_HROBJID_LIST
Cardinality     0..n
I have another component: Component B Where I want to bind a table to this interface node.
In component B :
1. I definied the Componenet Usage of component B in the componenet controller.
2. I drag & drop the IF_HROBJID node to the component controller's context (the node is mapped)
But when I try to bind a table, I always get the " The Mapping to Node COMPONENTCONTROLLER.1.IF_HROBJID Has Not Been Completed. " error.
nd_if_hrobjid = wd_context->path_get_node( path = 'IF_HROBJID' ).
nd_if_hrobjid->bind_table( lt_if_hrobjid ).
Can someone tell me what is the problem, and how can I solve it?
Thanks
N.

Hi,
Here you are trying to use component A in component B right?
Then what you need to do is:
1. Declare the component usage of A say A_USAGE in properties tab of component B.
2. Create a node say 'DATA' in component controller of component B. The node 'DATA' would have the same structure as the node in your component A.
3. Fill the node 'DATA' in component controller's method.
4. Under your webdynpro component B, you will see Component Usages -> A_USAGE. open interface controller inside that.
    Goto context tab and drag the 'DATA' node from component controller of B on to the node in interface controller.
Hope this is clear!

Binding 2 Models in the Same component controller

I'm using 2 Import Adaptive RFC Models. I want to bind both the models in the component controller of the same web dynpro component.
But when I try to do model binding for the second model, it does not allow me to do so. If I try to bind the same model in a different project, it happens perfectly and works fine. That means the model i.e. the BAPI is perfectly ok.
Can anyone please tell why is it not allowing to bind 2 models in the component controller of the same web dynpro component?

Hi Satyadev,
   If I undersatand your description properly, you have 2 models nodes in a webdynpro component, and you want to bind these two together. If this is the question, then, yes you cant do the bindings declaralatively, you have to do it dynamically...
Look at the code snippet below, it may help you...
Suppose ChildNode1 and ChildNode2 are the model node in the context of the component controller. Then you can map these two nodes dynamically....
wdContext.wdGetAPI().reset();
     IWDNodeInfo testNodeInfo1 = wdThis.wdGetAPI().getContext().getRootNode().getChildNode("ChildNode1", IWDNode.LEAD_SELECTION).getNodeInfo();
     IWDNodeInfo testNodeInfo2 = wdThis.wdGetAPI().getContext().getRootNode().getChildNode("ChildNode2", IWDNode.LEAD_SELECTION).getNodeInfo();
     testNodeInfo2.setMapping(testNodeInfo1, true);
     testNodeInfo2.addAttributesFromDataNode();
Hope this helps,
Please let me know if I have not understood your question properly...

Accessing component controller node

Hi..Experts,
How to access component controller node from WINDOW (please give me a sample code ) .
I want to set data to component controller node.
please help me.
Regards,
Siva

Hi siva,
Its very easy u need not to do any extra coding to share data between window context and component controller context.
Step 1) u create the node in component controller and map this node with window context.
step 2) Now in any method of window u write the set_attribute or bind_table statement ,your data will automatically transported to component controller .
So u dont need to do any extra coding for this.
Hope this will help your requirement.

How to work with the component controller.

I Created a Z component.
In that component controller i ceated a context node by using value node with BUT000 with the attribute NAME_ORG1.
I created a view in the same component.
In the view i created a Context Node BUT000 wiht NAME_ORG1.
I bind this view context node with compnent controller context node.
I want set the value from the view context node to component controller context node. How it is possible?
I created another Z component.
I created compoent controller like same context node above.
I created the view also.
I want display the first compoent controller data in the second component controller.
How it is possible.
For one component to another component we can pass the data based on component controller only?
Please give me how i can set/display the component controller context node with the data?
Thank You.
Regards,
B. Krishna.

Hi Manish.
    Thank you for reply Manish. I need some more information.
I created ZCOMP1 with view V1 and ZCOMP2 with view V2.
In both component controllers I created Context node by usng NAME_ORG1 of BUT000.
I provide the Navigation link from ZCOMP1 to ZCOMP2 as well as ZCOMP2 to ZCOMP1.
In Run Time Repository I provied two components as a INTERFACE VIEWS and
I provide ZCOMP2 as component Usage in ZCOMP1 as well as ZCOMP1 as a Component Usage in ZCOMP2.
Now, what ever data I entered in ZCOMP1 like NAME_ORG1 is "HELLO" then
This infomation I want display in ZCOMP2 - V2.
In ZCOMP2 method wd_usage_initialize
I write like this.
IF IV_USAGE->USAGE_NAME = 'CompUsage'.
    iv_usage->bind_context_node( iv_controller_type = cl_bsp_wd_controller=>co_type_component
                                   iv_target_node_name = 'BUT000'
                                   iv_node_2_bind      = 'BUT000' ).
ENDIF.
But it is displaying the Exception like this
Cannot display view ZCOMP2/MainWindow of UI Component ZCOMP2
An exception has occurred Exception Class CX_BSP_WD_INCORRECT_IMPLEMENT - The view controller or custom controller "" was implemented incorrectly

Binding model nodes - seeming repetition?

Hello,
When creating a WD app using Adaptive RFC Model (or any model I assume), it is necessary to create a data link between the Model and Component Controller. Visually, the fields of the nodes of the Model and the fields of the model nodes of the Controller are linked. Why, then, is it necessary to again bind the model node of the Controller to the model object using the ".bind" method?
Code as shown here is a classic example:
     Bapi_Usr01Dohr_Getemployee_Input bapiInput = new Bapi_Usr01Dohr_Getemployee_Input();
     wdContext.nodeBapi_Usr01Dohr_Getemployee_Input().bind(bapiInput);
     bapiInput.setId("MY_USERID");
     try {
          bapiInput.execute();
     } catch (Exception exc) {
          IWDMessageManager msgManager = wdComponentAPI.getMessageManager();
          msgManager.raiseException(exc.getMessage(), true);
Clearly the visual binding in the diagram view of the component controller and the programmatic binding using the .bind method of the model node are doing different things. My question is, what is the difference? Why are both required?

Michael,
There are actually 3 activity types, and sadly one of them has not the best name:
1. Map at run-time / design-time model to context node (make metadata structure, that mimics model structure, possibly with renaming of target attributes / sub-nodes)
2. Map at run-time / design-time (or as you say "link") 2 nodes in different controllers (make metadata structure, that mimics structure of node's metadata in another controller, possibly with renaming of target attributes / sub-nodes)
3. "Bind" at run-time-only data to node, that was previously described as metadata either using IDE at design-time or at run-time.
So, there is no repetition: you create metadata once (ok, more logically "once" then physically), then you may assign different data to resulted node via bind several times.

Difference between custom controller and component controller

Hi All,
I am a beginner in CRM SAP .
Please can anyone tell me whats the difference between custom controller and component controller with some scenario.
I am totally baffled.
Thanks in advance.
Regards
Shilpi

Hi Shilpi,
The main difference between custom and component controller is the role which they play during data transfer.
a) Custom controller is used for data transfer across two views within a component. For that you need to bind view context nodes to custom controller either through wizard or manually by adding the code in CTXT class create_contextnode method:
initial setting for depandant model node
    coll_wrapper =
      BTADMINH->get_collection_wrapper( ).
    TRY.
        entity ?= coll_wrapper->get_current( ).
      CATCH cx_sy_move_cast_error.
    ENDTRY.
    IF entity IS BOUND.
      BTOpportH->on_new_focus(
                   focus_bo = entity ).
    ENDIF.
b)Component controller is used for data transfer across two views in two different components. For this, we need to define the component usage first and then bind the context nodes in the method-WD_USAGE_INITIALIZE of the Component Controller impl class.
    WHEN 'ComponentUsageName'.
      iv_usage->bind_context_node(
                  iv_controller_type = cl_bsp_wd_controller=>co_type_custom
                  iv_target_node_name = 'ContextNodeName' "#EC NOTEXT
                  iv_node_2_bind      = 'ContextNodeName' ). "#EC NOTEXT
Hope this clears some of your doubts!
Thanks and Regards,
Rohit

Issue in Binding Custom controller to Component Controller

Dear All,
I have enhanced a standard component ERP_H.
I created a custom controller with context nodes BTSTATUS, BTSTATUSH
I enhanced the component controller with context node BTSTATUS, BTSTATUSH
Now when i try to bind the custom controller to component controller using this code in the context class of my custom controller
bind to component controller
owner->do_context_node_binding(
           iv_controller_type = CL_BSP_WD_CONTROLLER=>CO_TYPE_COMPONENT
           iv_target_node_name = 'BTSTATUS' " component controller context node
           iv_node_2_bind = BTStatus ).
its not working since this context node in component controller is not the standard one but the custom added one.
Am i missing something, or is there any way to bind customer context node in custom controller to customer context node in component controller.
regards,
pradeep

Hi pradeep,
    Try the other way round go to the context class in the component controller and paste the following code in the
create_contextnode( context node = name of the node to be linked).
*owner->do_context_node_binding(
        iv_controller_type = cl_bsp_wd_controller=>co_type_custom   <-----linking from component to custom
        iv_target_node_name = 'BUILHEADER' "target node: component controller node
        iv_node_2_bind = BUILHEADER ). "source node: current node.
See if this works.
Thanks

We could resolved the problem by creating new DC project
and copying the content of existing Dc project into new DC.
(Also created new activity for this new DC), Build & Deploy the project.
Now we are able to activate the new activity without any error.

Error in model node binding

Hi All,
I am facing some strange problem of model node binding.I have bound the model node to a model class.I am using Wizard to generate this model node binding.
To deploy this DC I am using NWDI .But the activation step is failing because of some build errors.moreover these build errors are not appearing at design time!!
CBS error log is as below :
[Error] com.bhc.nextgen.sales.suppcatapp.SuppCatLookupComp --> ContextModelNode Zrfc_Sd_Quote_Supplier_Search_Input [modelClass]: The context model node has not been bound to a model class (Hint: A Context model node has to be bound to a model class or mapped to a model node of another controller.)
Dose anyone know how to solve this?
Thanks,
Kanchan

Hi
I'm not sure if I understand you completely but instead of manually creating a model node which you bind to your model you could - in Diagram View - right click on the Data link and drag and drop your model from right to left and it will automatically create the needed model class references etc.
