CE: Mapping from Component-Controller to Component-Interface

Hi experts,
how can I map the context of a component controller to the component interface? There is a predefined data link between them but I do not find any possibility to edit this link.
Thank you for each hint,
Christoph

Hi,
Copy the context node from the component controller and paste it to the interface controller.

Issue while calling COBOL program from Component Interface in PeopleSoft HRMS 9.2

In HRMS 9.2, I am facing problem while calling the remote call function through component interface. In GP_ABS_EESS_REQ (Navigation Main Menu > Self Service > Time Reporting > Report Time > Absence Request) component, we have “Forecast Balance” button as shown below:
This button checks for eligibility for leave being applied. While using component interface, it executes FORCAST_PB field change event peoplecode which contains a remote call to a cobol program as below:
RemoteCall("PSRCCBL", "PSCOBOLPROG", "GPPOLRUN", "NET_RETURN_CD", &NET_RETURN_CD, "NET_TXN_ID", &NET_TXN_ID, "NET_TXN_NUM", &NET_TXN_NUM, "NET_MSG_ID", &NET_MSG_ID, "NET_MSG_PRM_CNT", &NET_MSG_PRM_CNT, "NET_MSG_PRM1", &NET_MSG_PRM1, "NET_MSG_PRM2", &NET_MSG_PRM2, "NET_MSG_PRM3", &NET_MSG_PRM3);
I am getting following error while executing it via component interface:
(2,148) - Think-time PeopleCode event (RemoteCall), but a SQL update has occurred in the commit interval. (2,148) FUNCLIB_GP_ABS.FCST_PB.FieldFormula Name:Abs_ForecastExec PCPC:5311 Statement:60
Called from:GP_ABS_EESS_REQ.GBL.DERIVED_ABS_SS.FCST_PB.FieldChange Statement:26
(91,34) - Error changing value. {Z_GP_ABS_EESS_REQ_CI.FCST_PB} (91,34)
(18,2) - Data being added conflicts with existing data. (18,2)
(91,37) - Error saving Component Interface. {Z_GP_ABS_EESS_REQ_CI} (91,37)
After commenting out this line of code, I was able to save the CI successfully. But I need to execute this statement before saving CI so that I can check the eligibility for leave being applied. Can anyone help me on this issue?

When I tried to read the file using `CAT -vt <filename>`, I could see that the file contains special characters such as ^M and ^I. This may be because of the file transfer mode(but I transferred in ASCII mode, still the special characters where appearing).
I opened a VI editor and pasted the same script. Save the file, tried to run the script, It was working fine.
I still didn't get how the special characters appeared. I used notepad++ as my editor.

Dynamic component interface context mapping

Hi all,
I got 2 component A and B. Component A use component B.
I would like to know how to set interface context attribute value of comonent B within a view of component A in programatic mode.
It should be something like this:
wdThis.wdGetCompBInterface().wdGetContext.setAttr1("OK");
is it possible???
thank u in advance,
Stefano

Hi
In your query consider B has BA Context which you want to fill from main componetn A
Yes it is possible to add values from A to B but I did it only through context mapping instead of direct refrence of interface controller .
For that you need to do context mapping .
1) Add B into A as used Web dynpro component .
2) Add controller refrence in Component controller using properties of WDC.
3) Map the context element from Interface controller to Component controller
Set values of context of component controller which will set values for context
of A
4) Only issue here is if you want to refresh values frequently you might need to create and destroy component each time . Not sure about it . In my case I m intitalising all context of B in init of A itself.

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,
Sam

Component Interface , INterface controller in WEB UI

Hi Experts,
Can anyone tell me what is a component interface, component usage , Interface controller and interface view?
I am a beginner in WEB UI and is getting confused with these terms.
Please help.
Many Thanks,
Neeraj

Hi,
component interface -> interface view:
Here you can define which Comp/Window should be accessable from outside the component
For example: COMP_1/MainWindow in component interface means this can be accessed as usage from other component
component interface -> interface controller:
In this node there is 2 child nodes: Context and Events:
I don't know how to use Events. But in Context you can add context node from component controller, which can be accessed from outside. This is specially important, when you want to bind two context nodes from two different components.
You can see how this can be used in component controller class in the method WD_USAGE_INITIALIZE
component usage:
Here you can define a usage of of other component.
For example: In your COMP_2 you can create a usage from other component (COMP_1/MainWindow).

Steve

Wda: call method from a component interface definition (cid)

hello,
I created the following scenario:
- I have a Main-component "m"
- "L" is a component interface definition (cid) which force both cid-L-implementating components "L1" and "L2" to extend and fill the method "set_COMP_USAGES()".
- I have other cid´s (A-C) too
- at runtime only one of the components "L1" or "L2" is created and the mother-component M holds component-usages (ref to) of the chosen variants of A-C and L as an attribute in the component-controller of m.
now my problem: my aim is to call a method in m at runtime which is defined at designtime in my cid L (set_COMP_USAGES() )and decided at runtime which variant of this method is chosen (the one from L1 or L2). in this method the references of comp_usages other cid´s should be passed to L1 or L2.
or short: how can I call a method from a cid-implementating component at runtime via a IF_WD_COMPONENT_USAGE reference (ref to) to this component?

I got the solution:
data: L_INTF_CONTROLLER         type ref to ZIWCI_Z_ITF_CID_L.
L_INTF_CONTROLLER ?= wd_this->COMPONENT_USAGE_L->GET_INTERFACE_CONTROLLER( ).
CALL METHOD l_intf_controller->set_comp_usages
    EXPORTING
      comp_usage_a = wd_this->COMPONENT_USAGE_a
      comp_usage_b = wd_this->COMPONENT_USAGE_b
      comp_usage_c = wd_this->COMPONENT_USAGE_c.

Web Dynpro - How to set and get info from Component Controller

Hi Gurus!!!
Im having some problems getting and setting info in component controller of my Web Dynpro.
I can't see the difference between View Context and Global Context.
How can i create a Global Context Between two views?
Thanks!
Regards.
Polakinho.-

hii
difference between view context and global context is we can use the same component controller for all the views in the same application.but when when we create node in view context then it will be available for that view only not for any other view...so if we want to use the same node for all the views we need to create that view in the component controller.so it will become global for that application.
for using global node you need to map that context in view controller.for that you need to go to that view then click on context tab and drag and drop node from component controller.so it will be available for that view.i hope it helps you.

how can we read the data from component controller to view controller.
what is the code for retreving the data from attribute in component controller into view controller.

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,

Can anyone help in sending the right input xml to component interface?

I do the same thing.
Take wsdl from axis and save it somewhere.
Then you can create a standard project in Oracle BPEL PM. Create partnerlink, give a name and click on first icon to take your wsdl. It will add some needed code, you answer always yes. Then you can create receive, assign, invoke, assign and callback or similar and deploy it.
Try it through BPEL Console...

Call a method in the view from Component Controller

Hi Friends,
I have written the code for calling the RFC in Component Controller.
My requirement is to change the properties of UI elements in the view, if I get any exception while calling RFC.
Can Call a method in the view from Component Controller.
Regards,
Lakshmi Prasad.

HI,
You can get the error message during the exception of calling RFC in view itself.
Any way you may call the RFC at some action in the view only.
Can you explain me what you are trying to do?
Kind Regards,

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.

Paul

Regarding Component interface controller

hi all
Can anyone explain me use of Component Interface Controller under Component with example.
Thanks in advance
Imityaz

Hi,
Interface Controller
One Web Dynpro Component may declare the use of another Web Dynpro Component to form a u201CParent-Childu201D usage relationship. In such cases, the only point of interaction between the parent and child components is the functionality found in the childu2019s interface controller.
if an interface controller is part of a component interface, the controller editor is in change mode and the context, the events and the methods can be implemented and edited directly.
Refer this thread,step by step procedure is there.

wdComponentAPI.getMessageManager().reportSuccess("fireToMenuView");
wdThis.wdFireEventToMenuView();
Now I have created an event handler "handleToMenuView" in the MenuView and subscribed the event handler to the event in Component Controller.
The control is reaching to the fire event in component controller but not to the Event handler in view controller.
What am I missing.

Nikhil
