Calling a method in view from component controller?

Hi,
Is it posible to call a method that is defined in the Component Controller in the View?
If it is posible please give some sample code how to call the method?
Regards,
Padmalatha.K

Padmalatha, all the methods defined in a controller from 'Methods' tab are instance methods. An instance method defined in a component controller is callable from any view controller that holds a reference to the component controller.
Defining methods between the tags
//@@begin others
//@@end
is useful if you want to declare static methods.

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?

Call JavaScript method in FXML from java controller

I have fxml like
 <fx:root type="javafx.scene.Group" xmlns:fx="http://javafx.com/fxml">
 <fx:script>
 function applyState(oldState, newState)
 </fx:script>
 ....and controller to it.
The idea is to move some view logic to fxml file.
So, when I need to change some view state, I want to call applyState from java code.
The question is how to do it.
What I have found:
We can get
fxmlLoader.getNamespace().get("applyState")and receive sun.org.mozilla.javascript.internal.InterpretedFunction.
NetBeans see this class. But while building the project i have an error
error: package sun.org.mozilla.javascript.internal does not exist
But this class really exists in rt.jar in JRE.
After that I have stopped digging into this.
I suspect that using internal API is not a good idea to call this InterpretedFunction.
Can somebody suggest how can I make such an invocation?

Until JavaFX doesn't expose the ScriptEngine instance of FXMLLoader, there's no way to communicate (Java <-> Javascript) with the <fx:script>.
But, if you want to rely on a hack, you can do this:
 private ScriptEngine extractScriptEngine(FXMLLoader loader) {
 try {
 Field fse = loader.getClass().getDeclaredField("scriptEngine");
 fse.setAccessible(true);
 return (ScriptEngine) fse.get(loader);
 } catch (IllegalAccessException | NoSuchFieldException | SecurityException ex) {
 Logger.getLogger(BrowserFXController.class.getName()).log(Level.SEVERE, null, ex);
 return null;
 }

Call a view's method from Component Controller.

Hi
Is it possible to call a view's method from Component Controller.
Regards
Nikhil

Hi Tummuru,
I have created an event in Component Controller by the name toMenuView. Now I created a method in which this event is getting fired. Foll. is the code of the method.
public void fireToMenuView( )
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.

Calling view controller method from component controller method

Hi,
Is there any way to call view controller method from component controller method?
Thanks,

Hi Khandal.
You should not make you component controller dependent from a view controller.
But what you can do is to define an event in the component controller. The view
controller can register for this event.
In the stage where you currently want to call the view controller method just fire
the event. In the event handler method in the view controller you can call the
method then.
Why do you need to call a view controller method? Can you give more details
about the scenario?
Cheers,
Sascha

Calling a method in another webdynpro component

Hi,
I have two webdynpro components say Comp A and Comp B.
In Comp A I had a view View A and in Comp B I had a View in View B.
In View A, I had a method X, I want to call this method in View B of Comp B.
How I can do this?
I created a public part of Comp A and tried to add in used webdynpro components. But in the list I am not able to find it.
Please help.
Regards
MQ

Hi,
If both the components Comp A and Comp B are in the same DC you can use the interface controller to call the method in comp A. Add this comp A interface controller in Comp B controller by going to the properties tab, so that you can access the methods of comp A interface controller.
If you have the components in different DC's you can follow the below steps:
Go to public parts in DC meta data section and create a public part by selecting the first radio button option and add the Comp A by selecting the option (Webdynpro Component-->Selected Entities).
Click on Finish button so that public part for comp A is created.
Now build the DC and go to Used Webdynpro components of CompB, give some name and browse to select the used webdynpro component, it will show you the Comp A public part select it and try to finish it.
Once again build the Dc after doing this.
Now you can access the method of comp A in Comp B
wdThis.wdGetCompA.getX()...
Hope this helps you..

Saleem

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.

View raises Component Controller Event

Hello,
I defined an even onUpdate in the component controller. A custom controller subscribed to this event. For that I have a method handleOnUpdate in the custom controller. Now I want to raise this event in a view after pressing a submit button of this view.
How can I raise the event?
So data flow would be:
1. Button pressed in view
2. Raise event in component controller
3. Handle raised event in custom controller
Regards
Rene

Hi Rene,
Your scenario is like:
View: OnSubmit -> Component Controller: OnUpdate -> Custom Controller: handleOnUpdate.
For this, in the code for OnSubmit in your view, you need to add code as
wdThis.wdGet<ComponentControllerName>().onUpdate();
and in the OnUpdate method in Component Controller:
wdThis.wdGet<CustomContControllerName>().handleOnUpdate();
Also, you need to add the Component Controller to your View, using Properties Tab
and Custom Controller in Component Controller, using its properties tab.
Hope it helps.

Alka.

Call method of interface controller from component controller

hi,
I have created one method in the interface controller of a component. Now i have this method along with attributes to the component controller. Now from the component controller i want to call the method of the interface controller. How do i do it???

Hi,
You dont need to call the method from the interface controller when you are in the same component.
You can call the method which is in the component controller.
Interface controller is used to expose some methods to a different component.
Ex Comp a want to expose a method which will be used by comp b then you need the interface controller in comp a.
Comp b will use comp a as used component
then it will invoke the methods.

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
