Hi,
i have a understanding Problem here.
In my View BERUFUNGSVERFAHREN is a ButtonChoice Element called "LV_1_BUTTON" with 3 Action Items in it.
the goal was to set a Action Item dynmamicly
this is my Coding in my View BERUFUNGSVERFAHREN
DATA lo_view TYPE REF TO if_wd_view.
DATA lo_buttonchoice TYPE REF TO cl_wd_button_choice.
DATA lo_menuactionitem TYPE REF TO cl_wd_menu_action_item.
* Get a reference to the ButtonChoice view object
lo_view ?= wd_this->wd_get_api( ).
* lo_buttonchoice ?= lo_view->get_element( 'LV_1_BUTTON' ).
* lo_buttonchoice->SET_SELECTED_ACTION_ITEM( 'RUF_1_NEUTRAL' ).
lo_buttonchoice ?= lo_view->get_element( BUTTON_CHOICE_ID ).
lo_buttonchoice->SET_SELECTED_ACTION_ITEM( ACTION_ITEM_ID ).
This workes fine for me in my VIEW but now i want to push this coding in my Componentcontroller to use as a method. (MVC-Modell)
And there i got this Dump "Dynamischer Typkonflikt bei Zuweisung von Referenzen "
I think this is happening because of my first line
DATA lo_view TYPE REF TO if_wd_view.
if i am right, maby i need to get first the reference of the VIEW ? Because i am now in my Componentcontroller.
Can u Help me here please.?
kind regards
tk
Hi,
Create an attribute in component controller with type if_wd_view and pass value to that attribute in doinit method of that view.
In component controller method use that attribute to habe view instance.

@ Paul Sudhakar,
i Think u mean the right thing
my Solution was this:
i Created an Context-Attribute in my View
VIEW_WD_IF type ref to IF_WD_VIEW
Then in the Method WDDOMODIFYVIEW
i exportet the View Parameter to my context attribute VIEW_WD_IF
My Attribute was mapped with my CC so now i can easily use the Attribute in my CC Method for my Button Choice Method.
I used this coding im my CC Method
* get single attribute
LO_EL_VIEW_DETAILS->GET_ATTRIBUTE( EXPORTING NAME = `VIEW_WD_IF`
IMPORTING VALUE = LV_VIEW_WD_IF ).
LV_VIEW_WD_IF->GET_ELEMENT( BUTTON_CHOICE_ID ).
DATA LO_BUTTONCHOICE TYPE REF TO CL_WD_BUTTON_CHOICE.
DATA LO_MENUACTIONITEM TYPE REF TO CL_WD_MENU_ACTION_ITEM.
* Button wird auf Neutral zurückgesetzt
LO_BUTTONCHOICE ?= LV_VIEW_WD_IF->GET_ELEMENT( BUTTON_CHOICE_ID ).
LO_BUTTONCHOICE->SET_SELECTED_ACTION_ITEM( ACTION_ITEM_ID ).
