Error in GP CO(comp interface controller code) implementation

Hi Frndz..
I have 3 quires on GP n itz configurations those
1)Am developing an GP callable Object , am following this doc
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0957cb6-5103-2a10-6d9d-a0a4d68c8bf1
In the Interface component controller when i opend implimentation tab by default am getting an error like IGPWebDynproCO object has defined out of the class.
And when an adding the IGPExecutionContext ele in bigen others also itz showing an error that this can't be resloved eventhough if am using Organise imports.
Am using EP7.0 and WDP is 7.0.11 n JDK is 1.4.2_12.
2) I gone through the "Time -Off process" in GP, in this app the approvel levels and approvers are declared at design time(offcourse approves can be at runtime also), i want to know how can we declare the approvel leves and approvers at run time , means as per the login user we need to decied his approvers n his approvel levels at runtime.
3)In my laptop i installed EP 7.0 trail version n NWDS 7.0.9 n am using JDK is 1.4.2_09
and in my laptop in "Time-Offprocess" i tried to edit(inactive) the process so itz giving Null pointer Exception but this not the case in my office server there itz doing well.And i placed the GP_API n TopLevel DCs in my NWDS 7.0.9 eventhough am not getting caf/eu/gp/api n caf/eu/gp/api/wd in my laptop but in my office IDE itz working.
If anybady have any suggestions plz share with me
Thnaks in Advance
Regards
Rajesh

RM CL-51 laptop driver missing (intel(r) 82801DBM LPC Interface Controller CODE 28

As the heading i have an UNKNOWN DEVICE with a yellow ? beside it. the only thing i can see is it is to do with intel(r)82801DBM LPC Interface Controller with the CODE28 which is no driver installed. I went to intel and downloaded and installed the R114079
driver but still the same. I have tried downloading the drivers from RM and running them but again no help. Can anyone help me with this. it would be much appreciated. i have just bought the laptopwith a fresh install so i think there is a missing driver but
i cannot find it.,....

Unfortunately the hardware drivers are the sole responsibility of the hardware manufacturer. If the device is defective then there is nothing you can do in Windows to make it work. You will have to have some hardware diagnostics run on your system
by a computer repair technician. Troubleshooting hardware problems are not within the scope these forums.
You might obtain more information about the controller in one of the Intel forums where you will find people much more qualified to discuss issues with Intel hardware than here.
Your Intel 82801 chipset is part of the Intel southbridge family:
http://www.intel.com/design/chipsets/datashts/290655.htm
Otherwise you will have to discuss the problem directly with RM technical support.

Design question: Interface Controller vs. component controller

Hello,
I have a component A. This component has a component controller (compController) and an interface controller (intController).
Component controller has method compMethod()
Interface controller has method intMethod()
- Am i allowed to call intMethod from component controller? ( i'm pretty sure this isnt bad design because this is also done in the tutorial on eventing)
- Am i allowed to call compMethod from intController or is this bad design?
- Am i allowed to subscribe compController to event in intController or is this bad design?
Kind regards,
Joren

Hi Joren,
like Valery already pointed out, we recommend not to implement any logic in the component interface controller but only implement methods used for delegating logic to the component controller. This is based on the fact, that the component interface controller will be implemented by the component controller in the the next major SAP NetWeaver Release. This means that it will not have its own Java class like in NW04 and NW04s. To simplify migration the interface controller code should be as slim as possible by applying the delegation principle.
You wrote:
- Am i allowed to call intMethod from component controller? ( i'm pretty sure this isnt bad design because this is also done in the tutorial on eventing)
Yes, my (very old) tutorial on serverside eventing exposes a public method fireEvent() which is invoked by the component controller. In early versions of NW04 the wdFireEventInnerEvent() method was not exposed in the IPublic-API of the component interface controller but only in the IPrivate-API. Therefore an additional method fireEvent() must be defined to fire the event from another controller. As a negative side effect, this public fireEvent() method is also exposed by the IExternal-API of the component interface controller so that the event can be fired from outside (by the Embedder component) which is not desired in most cases.
Meanwhile the wdFire<event name>() method is exposed by the IPublic-API of the component interface controller, so that the public method fire<Event name>() is no longer needed.
I will update the tutorial in this respect so that it again propagates best practices.

Code example using interface controller ?

Hi, guys:
I have a question.
In CRM UI, I need to integrate one component with another component, and I want to pass the value from 1st component to 2nd component using interface controller. Does any one who have done this before and have a code example?
Really appreciate!
Eric

Interface Controller context model attribute error

I am trying to create a controller interface as such: I created a DC that goes out and retrieves SAP ID using a RFC call. My controller context is bound to a RFC model. I'd like to expose the SAP ID that comes back from that call within a model attribute to other components. I try to create a model node and corresponding model attribute within the Interface Controller, setting the isInputElement = true. However, as soon as I do this I get a number of compile errors:
"The context model node has not been bound to a model class", "The context model attribute has not been bound to a model property".
Are you not allowed to map model nodes to an interface?

Karla,
First, set isInputElement to false. Think again, you are exposint "result" outside but not collecting "input" from outer component.
Next, calculated attributes to the rescue here.
Say, in component controller you have 1..1 / 0..1 model node SapIdQuery_Input with 1..1/0..1 child SapIdQuery_Output that holds System_Id attribute, type string.
Now create in component controller context (right below root node) attribute System_Id of type string, set read-only to true and calculated to true. Switch to source editor and write the following for generated attribute "getter":
if (wdContext.currentSapIdQuery_InputElement() != null &&
 wdContext.currentSapIdQuery_OutputElement() != null)
return (String)wdContext
 .currentSapIdQuery_OutputElement()
 .getAttributeValue("System_Id");
else
return null;
Now add controller usage (of component controller) in interface controller and map attribute in interface controller to calculated attribute in component controller.
If you expirienced problems with mapping, try to create calculated attribute in 1..1 subnode of root context node.

Hi ,
Have you walk thru the Excel application then it wold be the simple.
First create the comp2 and add theserveice what u said and create the comp1 and create ur button in your View.
In Comp2 crete the a method like in component controller exportToExcel2003() and implemet your code for displaying the popup also .
that would be like this.
public void exportToExcel2003( com.sap.tc.webdynpro.progmodel.api.IWDNode dataNode, java.util.LinkedHashMap columnInfos )
this.openExcelLinkPopup();
private void openExcelLinkPopup() {
 excelLinkWindow =wdComponentAPI.getWindowManager().createModalWindow(wdComponentAPI.getComponentInfo().findInWindows("ExcelLinkPopup"));
 excelLinkWindow.setWindowPosition(WDWindowPos.CENTER);
 excelLinkWindow.open();
//begin
// private member variable for storing instance of an opened popup window.
private IWDWindow excelLinkWindow;
//@@end
And you mentioned this name in interface controller
and configure this mehod as in comp1 Create on Demand
And you can utilize in the Ur button of comp1 first View
register this to ur view ExcelExportComp Interface Controller
In Button on action u add the code like this.
wdThis.wdGetExcelExportCompInterface().exportToExcel2003()
This might helps you .
Or gothru applciation that will useful or not getting post your issues
Thanks,
Lohi.

Error when trying multiple inbound interface determination for IDOC

Hi !
I have this scenario: File -> XI -> IDOC.
For each source file, I need to send multiple idoc packages, all to the same business system, but each package should be the result of different interface mappings.
All mappings have same source and target message types...e.g. source: MT_MyFile, target: CREMAS04.
To avoid creating a generic mapping program, we need to duplicate the current mapping program, make it handle the new case, and then add it as second interface mapping in Interface Determination, with same inbound interface, but different interface mapping, without conditions. All interface mapping should execute.
We are receving this error:
<SAP:Code area="IF_DETERMINATION">CX_ID_PLSRV</SAP:Code>
<SAP:P1>Inbound interface was found more than once (for same sender and receiver) for outbound interface urn:xxxxx/xxxx:.MI_xx_xxxxxxxx_xxx_xx</SAP:P1>
<SAP:Stack>Error when determining the inbound interface: Inbound interface was found more than once (for same sender and receiver) for outbound interface urn:xxxxx/xxxx:.MI_xx_xxxxxxxx_xxx_xx Inbound interface was found more than once (for same sender and receiver) for outbound interface urn:xxxxx/xxxx:.MI_xx_xxxxxxxx_xxx_xx</SAP:Stack>
Any clues?
Regards,
Matias.

Hi Satish !
Thanks.
I need to send different IDOCs to SAME business system.
In Interface determination I need this:
Inbound Interface -
Condition -
Interface Mapping
IF_1 no condition M_1
IF_1 no condition M_2
I need to send BOTH IDOC packages to same business system.
But it keeps throwing the posted error.

Matias.

UIButton tag not available in controller code

Hi, I have UIButton defined in InterfaceBuild. I assigned Tag (integer?) to the button. It has a IBOutlet in my controller code. But my controller can not retrieve the tag value by using:
int tag = mybutton.tag;
It is always 0 no matter what I set in Interface Builder.
Why?

I am new to interface builder and I'm not sure how to give each button a separate unique tag in interface builder. I can figure out how to access them in code once there set. This is probably something really simple that I'm missing.

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

Using Interface controller in OCA application

Hi,
My requirement is to pass information and screen control between two components in two different DCs.
My parent DC Component has to pass information to my child DC Component and also call the view assembly of the child DC.
I am using CE7.1 SP07 PAT003.
In my child DC I have created a component Interface Definition say ChildInterface. In the context of interface controller of ChildInterface I have added a string attribute. ChildInterface also has a view container.
Now in my Child component I add ChildInterface as my Implemented Interface. I map the window of the child component to the ChildInterface. To the view container I add the default view of the component.
Now I have created a public part and added the ChildInterface as an entity.
I add a dependency in my Parent Component to this child DC's public part.
At design time I can access my ChildInterface's context from my parent component. However, while adding a link from parent default view to ChildInterfaceView, it gives me an error. however on reload it suppress the error but doesnt open the java editors.
While trying to deploy the applications it gives me a deployment failure message.
Following is the trace-

Please help.

please do attach the trace files..
Meanwhile , just check the way you have implemented the interface and the interface defintion of achild node are correct.
Once the implementations are correct,there should not be problem in deployment.
Let us know if you need more info on interface definton creation ...

JDeveloper Error(16,8) 'class' or 'interface' expected

I have just installed JDeveloper for 11.5.10 RUP5 OA Framework and extended the Purchase Requisition Lines EO (PoRequisitionLineEO). Everything seemed to work okay. However, in the first step of deployment, to compile the .java class, when I select Make rnPoRequisitionLineEOImpl.java, I receive the following compiler eror:
Error(16,8): 'class' or 'interface' expected
My sense is that this may be an environment setup issue as this is the first time I'm using JDeveloper and the first time I am extending OA Framework.
Any advice on how to resolve?

This was an end-user error. Additional code had been added to the .java source code that was not in a class.

Use of interface controller

HI
can u please explain me use of interface controller with simple example along with the code
Thanks
kishore

Hi Kishore,
Here r the few facts abt interface controller:-
Used to control access from other components.
Is created automatically when a component is created.
Exists as long as its component is embedded in another
component.
This controller contains data, methods, and events that can be used by other Web Dynpro components.
A componentu2019s interface controller can be used by the embedding component for mappings, eventing, etc.
Interface for external users of a component: data transfer,
eventing.
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.
There is a usage declaration arrow pointing from the component controller to a child component. Notice that the arrow joins the child component at the top right-hand corner. This is the location of the childu2019s interface controller.
At no time does the Web Dynpro Runtime interact with a componentu2019s interface controller. It is only ever used to form a Parent-Child relationship between two Web Dynpro Components.
