In which situvation you will use interface controller and custom controller

in which situvation you will use interface controller and custom controller?

Hi rafi,
Custom Controller Custom Controller is as same as the component controller, here we can write the business logic.
Custom Controller means developer can create multiple controller denpeing up work.
By using component controller we cant create multipule contrllers. when we create the DC that time it will be created automatically.

Difference between interface view and interface controller

Hi,
What is the difference between interface controller and interface view?
When we will use interface controller and when we will use interface view?
How do we create an interface view?
How do we attach this interface view to a view in another component
Regards
MQ

Hi
Interface View Controllers
A) Implement event handlers which are called when ..
-starting (start-up plugs) Web Dypro applications
-a component is reached via navigation (inbound plugs)
B) Allow fireing outbound plugs (navigation)
C) Allow firing exit plug
D) Have no own context, public methods or events
Interface Controller of a Component
The interface controller of a Web Dynpro component contains all context nodes, events and methods of the component controller to which you assigned the Interface addition in the Controller Editor. These parts can be displayed in the interface controller view, although you cannot edit them here.
Interface Controller of a Component Interface
A Web Dynpro component interface can be created independently and defined so that it can be implemented later in any components (see working with Web Dynpro Component Interfaces in the Programming Manual of this documentation). That is why in this case you can define the context nodes, methods and events you require in the interface controller view. The relevant implementation then takes place in the component controller of the implementing component.
Check this links and work on it.

Change plug to interface controller in Netweaver 7.1

hi ,
We are moving to Netweaver 7.1 . Current my webdynpro application is hvng plug firing through interface controller . I hv read tht in 7.1 interface controller is abstract so tht we cnt fire plug from interface controller. I want to know how my my application ging to work in 7.1 Also where i need to make changes in case of firing plug in interface controller. Please also send me links on this topic.Thnx in advance.

HI Kavita,
There is no problem for fire plugs .in you application. As 7.1 supports backward compatibility.
If you want to migrate your application then you need to take care whatever coding you have done in interface controller.
and as plugs are defined in interface view controller. when migrating it will be converted according to new 7.1 structure.
please refer

How to create a method in Interface Controller

Hi Guys,
        I am working with webdynpro ABAP sample application "Component usage" . There i got a issue like i am not able to create a method in Interface controller. There i am not able to edit anything. Can anybody please let me know how to do that.
            Thanks In Advance
Regards
Ravikumar

Hi Ravi,
          Check This
If one Web Dynpro component (parent component) needs access to another Web
Dynpro component (child component) the parent component can declare the use
of the child component. A specific component usage instance is then created and
the parent component accesses the functionality of the child component via its
component interface controller.
The only parts of a Web Dynpro component that are visible to the user, are the
interface controller and the interface view(s).
All Web Dynpro components have only one interface controller. Via the
interface controller, data, methods, and event handlers can be exposed to
other components.
Interface views represent the visual interface of a Web Dynpro component.
There is a one-to-one relationship between a Window and an interface view.
Each time a window is defined, a related interface view is automatically
generated, which makes the window accessible from outside the component.
The interface view only exposes those inbound and outbound plugs to the
component user that have the interface property checked. Methods and
context data of the window are not accessible via the related interface view.
If the component has no views, there is no need to have Windows. In this
case, the component will not implement an interface view. Such components
having no visual interface are known as faceless components.

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

Interface Controller Issue

Hi,
Hope you can help me on this one. We're trying to use an interface controller to use an external Web Dynpro app in our current Web Dynpro project. Whenever we try to do some context mapping in our Wed Dynpro project, it seems that our Web Dynpro project (during build time) fails to identify context of our component controller (it gives an <insert context node name / context objects here> cannot be resolved errors).
Did anyone experience this error or would anyone know how to resolve this?
Thanks!
Angelo

Hi Angelo,
Please have a look at below document might helps for your issue In[Inter Application Communication and Navigation (Design Time) in WebDynpro|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0ae5f90-1679-2c10-4183-8c64cf932088?quicklink=index&overridelayout=true]
Suppose there are two DC1 and DC2.
DC1 having context node XYZ/attrubute available in DC1 component Controller and interface controller and mapped it properly.
- then build and deploy DC1.
- Now sync sources and sync used DC for DC2
- then click on component name of the DC2 and bind interface controller to component controller and drag n drop context node XYZ to component controller.
- once done then try to re-build and use the contect node XYZ
Hope it will helps

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.

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.

Direct Context Mapping of an interface controller

Hi all,
I want get 2 or 3 context attributes from an interface controller of another component. I can see the attributes that I want in the interface controller of the other component. I've been reading SAP documents and other posts and everything is concepts. How can I access those attributes to get the data. I've been reading and it sounds like you can do direct context mapping and external. I'm pretty sure what I need is the direct context mapping. The other component is an SAP component (LO_OIF_MAIN_COMP) and I can not make any interface methods of the component controller. So the only way that I can figure is to either call/make reference to the interface controller and get the attributes... but I can not figure out how to do it. Please help. I've been researching this for several hours now... and in my mind it seems like a pretty concept. Thanks.

Hi,
I guess this seems to be WD compoent usage. you can use the steps mentioned in any article for e.g. WD ALV component usage and find out how the context mapping is done.

WLAN Controller Displays Interface IP in Web Authentication URL Instead of FQDN

Hi,
Can someone offer any help with the issue below please?
I have a guest wlan configured on a Cisco 2106 WLAN controller. Guest users are redirected to a Web Authenticaion page when they try to access the internet through a web browser, and can only proceed by succesfully authenticating with the controller.
The problem I have is that the guest users are presented with an SSL certficate error before they hit the web authentication page. I have installed an SSL certificate from Verisign on the controller, and have configured an FQDN for the interface that is used for the guest wlan. However, the certificate error still persists because when the user is re-redirected to the web auth page, the URL in the address bar is presented as the IP address of the interface instead of the FQDN, For example, when a user is redirected, the address bar in their web browser displays; https://1.1.1.5/ instead of https://guestwifi.domain.com/ The SSL certificate that is installed on the controller is securing the FQDN of the interface.
I'm not sure if i'm missing something here, but i'm struggling to find how to get the FQDN to display instead of the IP.
Thanks,
Paul

I'm not following what you mean when you sayd "FQDN for the interface that is used for the guest wlan"......
I assume you configured the Virtual Interface to have the dns entry as guestwifi.domain.com but clients are still being redirected to the virtual IP itself and not the dns name?
The only reason I can think of for that happening was if the WLC had not been rebooted since applying the DNS name to the Virtual Interface (it takes a reboot to modify client redirect stuff, the same goes for http vs https).
so guestwifi.domain.com should have a DNS entry resolving to 1.1.1.5, that entry should be on your virtual interface, and upon reboot you should always redirect to guestwifi.domain.com unless you manually type https://1.1.1.5 in the browser.

Difference between custom controller and interface component

Hi,
Can anybody tell me what are the differences between component controller and custome controller , component interface.
Thanks in advance.
Regards
sireesha.

hi,
When any component is created web dynpro framework automatically generates the controller(controller is nothing but entity which controls the working of views and acts as a binding layer between model and view), this controller is called Component controller.
We can have as many controller as we want, but they should be used sparingly, Controller should encapsulate the functionality which is common to whole component , like if your application fetches master data and appliaction data so better you should have 2 controller , 1 for master and 2 for application so as to have modularisation in your application.
Component Interface is the entity which is used when you want to use the functionality defined in some other component i.e. if your main component is acting as a parent comopnent then the child component usage should be defined via this interface controller under Component Interface, so that main compo will access it via childs Interface Controller.
Other node under this , Interface view , gets generated for every creation of window , Interface view is entry point into our application for web Dynpro framework
jsut check out following links,

How to remove bullets and spacing for url links in the Related Links iview?

I tried to look for a property that I can edit the look-n-feel of the url links in the Related Link iView using "Theme Editor".
All I need is to remove the bullets and increase some vertical spacing between the links.
Currently, it looks like this:
URL iView A
URL Iview B
I go through the whole section of Related Links properties, none of them seems to do what I want.
Here are the list of properties in Related Link section (of Navigation Panel):
Link Color
Text Decoration of Link
Hover Color
Text Decoration of Hovered Link
Initially, I thought "Text Decoration of Link" should be the right property I should look at. But there are a drop-down with 5 options: None, Underline, Blinking, Overline and Line-Through, which really can't achieve what I want.
Thanks for advice.

Hi, Kai.
I checked the Related iView properties (URL Template), I don't see what layoutset it is really using. I am not sure, is that a layout set apply to the Related Link Iview?
For the regular KM iView, I will see what Layout Set I want to apply, then I can go and change the properties (of layout coontroller, collection renderer & resource renderer)you mentioned. But for this Related Link iView, I really don't know. I guess it may be in the code itself.
If there is a layout set for Related Link iView (or the place to apply layout set to it), can you point to me which one is that? (I did a search through the layout set names, I only find the AppQuicklinkExplorer (I used this for Dynamic Nav. Link iView before), if I can aply this layout set to Related Link iView, my problem will be solved.)
Thanks for help.

Windows 7 and DV6500t (ICH8M LPC Interface Controller)

I recently loaded (via dual boot) Windows 7 onto my HP dv6500t. All went fine and all is working OK except for one issue. In Device Manager, I have one unknown device. Looking at its properties, it shows a location of: "ICH8M LPC Interface Controller - 2815" and the driver is unavailable. I tried to use sp36881 (Intel Chipset Installation Utility for ICH8) from HP's site and this did not work. Any help?

Dear community,
This is about Motion control in Labview: I try to control a step motor by using a PXI 7350 controller and UMI 7774 to interface with third-party driver UDK5114NW2. The problem is 5 Disable LEDS on UMI 7774 board always lit even when I check "enable" on "Motion I/O setting" in configuration of PXI 7350 motion controller. Furthermore, when I start to control step motor, it is not working and I found disable LED on UMI board still lit. I don't know how to solve this problem. Can someone help me to figure out? Thank you in advance!
Hau Nguyen.

Dear Community,
I said wrong, 4 disable LEDS on UMI 7774 Board instead of 5 as my previous post. Why nobody help me to solve this problem. I can not turn off disable LEDs on UMI 7774 Board so I can not start the strp motor. Please help me!
