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.
Regards
Nikhil

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?

Call view's method from component_controller

Hello,
I need to call a view's method from a component controller.
Does anybody know how this can be done?
Thank you.

Hello,
Thanks for the info.
In this case. If I have a button on my ALV that takes a user to a different view how would that work?
Navigation is done using plugs. ALV is initialized in COMPONENT_CONTROLLER and it does no not have plugs. Would I have to create an object of a view where ALV is initialized and than call FIRE_TO_XXXXX_PLG method?
Thank you.

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?

Hook methods in component controller vs hook methods in view controller

Hi,
I want to know how WDDoInit in component controller differs from the same in view controller.
How the lifecycle flows in both controllers?
Eg. if i create a method intialize() in both component & view controllers and if i called initalize method in view, which one will be called?
Need to know how the flow works.
Regards,
Manoj

Dear Manoj,
Please check if it is helpful.
The order of execution of standard hook methods when a WDJ application is called the first time is as follows:
1. Component Controller DoInIt()
2. View Controller DoInIt()
3. Interface Window Controller
4. Component Controller DoBeforeNavigation()
5. Component Controller DoModify()
6. Component Controller DoPostProcessing()
After this, if you navigate to some other view, then the order of execution of methods of that New view will be:
1. Component Controller DoBeforeNavigation()
2. New View DoInIt()
3. New View onPlugfromFirstView
4. Component Controller DoModify()
5. Component Controller DoPostProcessing()
Then, if you again navigate back to the first view, then the order of execution of methods is:
1. Component Controller DoBeforeNavigation()
2. New View onPlugfromNewView
3. Component Controller DoModify()
4. Component Controller DoPostProcessing()

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

How to call Apps Module Custom Method from Entity Object / View Object ?

Hi All,
I create a custom method in AppsModuleImpl.java. How can I call that custom method from a setter method on Entity Object / View Object ?
(I have tried to use Configuration.createRootApplicationModule(amDef,config); but it is not the correct way, is it? )
Below is my code :
The setter on MyEntityImpl.java :
public void setKodeprd(String value) {
setAttributeInternal(KODEPRD, value);
if (getProduct() != null) {
// CALL the getSalesPrice custom method from here, HOW ??
The Application Module custom method :
public Number getSalesPrice(String priceCode, String kodePrd) {
Number price = new Number(0);
String [] theKey = {priceCode, kodePrd};
Key priceKey = new Key(theKey) ;
ViewObject SalesPrice = getSalespricedView1();
Row[] salesPriceRow = SalesPrice.findByKey(priceKey, 1);
price = ((SalespricedViewRowImpl)salesPriceRow[0]).getPrice();
SalesPrice.remove();
return price;
Thank you for your help,
xtanto

inside the EntityObjectImpl :
YourAppModuleImpl am = (YourAppModuleImpl)getDBTransaction().getRootApplicationModule().findApplicationModule("YourAppModuleorServiceName");

Hi Carlin,
You need to ensure that you raise the event:
e.g. here I raise an event to pass some data from an org chart:
lo_event =
     cl_fpm_event=>create_by_id( zpa_os_org_struc_flex_n_assist=>c_island_nav_up_requested ).
lo_event->mo_event_data->set_value(
           iv_key = zpa_os_org_struc_flex_n_assist=>c_node_selected_for_nav
           iv_value = ls_nav_node ).
wd_this->ao_fpm->raise_event( lo_event ).
Then you need to read the event. In the OVERRIDE_EVENT_GAF method you can read the event by referring to
io_gaf->mo_event
e.g.
io_gaf->mo_event_data->get_value( exporting iv_key = zpa_os_org_struc_flex_n_assist=>c_node_selected_for_nav
                                          importing ev_value = ls_node_detail ).
let me know if you need any other help/explanation,
Cheers,

How do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
 setAttributeInternal(REPLACEMENTPRICE, value);
 AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
 Key key = new Key(new Object[]
 { getPartNumber() });
 am.recordPartHistory(key); // AppModuleImpl method which records pricing history
 am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

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.

twinkal

Call Java Class and Methods from ABAP

Hi
I install de JCo, But how i can call java class and methods from ABAP?. somebody has an example?
The tutorial say that's is possible, but don't explain how do that?
Thanks.
Angel G. Hurtado

If you need only simple java program, you do not need to install JCo. The following codes can call java class.
DATA: COMMAND TYPE STRING VALUE 'C:\j2sdk1.4.2_08\bin\java',
      DIR TYPE STRING VALUE D:\eclipse\workspace',
      PARAMETER TYPE STRING VALUE 'Helloworld'. "here the name of your java program
CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE
   EXPORTING
     APPLICATION = COMMAND
     PARAMETER = PARAMETER
     DEFAULT_DIRECTORY = DIR
   MAXIMIZED =
     MINIMIZED = 'X'     "If you need the DOS window to be minimized
EXCEPTIONS
    CNTL_ERROR = 1
    ERROR_NO_GUI = 2
    BAD_PARAMETER = 3
    FILE_NOT_FOUND = 4
    PATH_NOT_FOUND = 5
    FILE_EXTENSION_UNKNOWN = 6
    ERROR_EXECUTE_FAILED = 7
    OTHERS = 8.
Tell me if it works.
