WebDynpro ABAP and Portal Navigation

[Former Member]

Hi,

I have two Webdynpro applications as an IView linked in the portal, now I want to navigate between the applications.

I know, that I can trigger a protal event by:

method ONACTIONFIRE_PORTAL_EVENT .
data: L_API_COMPONENT  type ref to IF_WD_COMPONENT,
        L_PORTAL_MANAGER type ref to IF_WD_PORTAL_INTEGRATION.

  L_API_COMPONENT = WD_COMP_CONTROLLER->WD_GET_API( ).
  L_PORTAL_MANAGER = L_API_COMPONENT->GET_PORTAL_MANAGER( ).

  L_PORTAL_MANAGER->FIRE(
        PORTAL_EVENT_NAMESPACE = 'my_namespace_for_Web_Dynpro_documentation'
        PORTAL_EVENT_NAME      = 'showCustomer'
        PORTAL_EVENT_PARAMETER = CUSTOM_ID ).

endmethod.
 

And catch the event by

method WDDOINIT .
data: L_API_COMPONENT type ref to IF_WD_COMPONENT,
L_PORTAL_MANAGER type ref to IF_WD_PORTAL_INTEGRATION,
VIEW type ref to IF_WD_VIEW_CONTROLLER.
L_API_COMPONENT = WD_COMP_CONTROLLER->WD_GET_API( ).
L_PORTAL_MANAGER = L_API_COMPONENT->GET_PORTAL_MANAGER( ).
VIEW ?= WD_THIS->WD_GET_API( ).
L_PORTAL_MANAGER->SUBSCRIBE_EVENT(
PORTAL_EVENT_NAMESPACE =
'my_namespace_for_Web_Dynpro_documentation'
PORTAL_EVENT_NAME = 'showCustomer'
VIEW = VIEW
ACTION = 'RECIEVE_CUSTOMER_ID' ).
endmethod.
 

But in which WDDOINIT I had to implement the code?

Best regards,

Marcus

So you just need to navigate between both WDA? You better use portal navigation then. There is help available on help.sap.com. To give you an idea:

1. Edit ONACTIONFIRE_PORTAL_EVENT

2. Press CTRL + F7 (Code Wizard)

3. Look for Portal Integration

4. Choose NAVIGATE*

You need to know the pcd - name of the iView in that case.

If you really want to go with portal eventing, the event subscriber must be already initialized at the beginning (when you fire the event). Portal eventing is used to share data between 2 iViews as far as i know.

HI Rene,

thanks for your answer.

I use your way to navigate to the UWL.

But in the other case I want to call a application with special informations from the frist.

Then you can pass url parameters. Please dont write to much code in WDOINIT methods. Because you cant read url parameters there.

In your window controller you have the inbound plug handler. There you read URL parameters and this method can call methods in your component controller. Sequence is like that:

1. WDO_INIT of comp. ctrl.

2. WDO_INIT of window. ctrl

3. WDO_INIT of view.ctrl.

4. Handle inbound plug

Those both applications are within the iView, are they?

Hello Marcus,

You have to implement in the WDDOINIT of the application that has to be launched on the portal event.
