How to find function codes of the buttons in ABAP Webdynpro

Question

I had 2 buttons in my input screen of the WebDynpro, for both buttons some piece of logic is common. So i wrote that common logic in the default method 'WDDOBEFOREACTION', which will be triggered always before the corresponding methods got triggered.
Now my problem is the method 'WDDOBEFOREACTION' triggering even when user hits ENTER in the input screen, to prevent the common logic not to execute need to write some condition based on the user action. But unfortunately was not able to find the way. Could any one suggest me on this.

Answer 1

For your specific requirement :
you should first determine the current action which triggered this WDDOBEFOREACTION method,
as this method triggers for every action performed on the webdynpro view.
For that below is the code
  DATA lo_api_view_controller    TYPE REF TO if_wd_view_controller.
  DATA lo_action                 TYPE REF TO if_wd_action.
  lo_api_view_controller = wd_this->wd_get_api( ).
  lo_action = lo_api_view_controller->get_current_action( ).
  IF lo_action IS NOT BOUND.
          IF lo_action->name EQ 'BUTTON1'   OR   lo_action->name EQ 'BUTTON2'.
Where BUTTON1 and BUTTON2 are the actions associated with both the buttons.
Write your common logic here and now it would get executed only for both these button cliks only
           ENDIF.
ENDIF.
