FPM : OVERRIDE_EVENT_GAF method of Component Controller

[carlin_willams]

Hello All

I am not able catch the button evenet value in OVERRIDE_EVENT_GAF method of Component Controller.

What i have done is

1) Created FPM Application with Road Map 4 Mainsteps.

2) In the First Road Map contains view, having two buttons. On click of buttons need to hide MainStpes

Example : On Click of Button1 need to show Step1 Step2 and Step3 means Step4 is hiding

On Click of Button2 need to show Step1 Step3 and Step4 means Step2 is hiding

3)For the above requirement In the View created two actions for two buttons. In Button1 action written below code.

Code for Button1 Action in the View

data: lo_fpm type ref to if_fpm,*lr_event type ref to cl_fpm_event.

• create event

lr_event = cl_fpm_event=>create_by_id(

cl_fpm_event=>gc_event_change_step ).

lo_fpm = cl_fpm_factory=>get_instance( ).

lr_event->mo_event_data->set_value(

iv_key = 'B1'

iv_value = 'BUTTON1').

4) onclick of Button 1 when i m trying to get the value of B1 it is coming empty in the OVERRIDE_EVENT_GAF method of Component Controller. Expecting "BUTTON1" written below code

Code for OVERRIDEEVENT_GAF method of Component Controller_

DATA: lo_fpm TYPE REF TO if_fpm,

lr_event TYPE REF TO cl_fpm_event.

• get reference to FPM API

lo_fpm = cl_fpm_factory=>get_instance( ).

• create event

lr_event = cl_fpm_event=>create_by_id(cl_fpm_event=>gc_event_change_step ).

lr_event->mo_event_data->get_value(iv_key = 'B1' ).

5) Based on condition planning to hide the steps.

Hi CW,

I think chris has explained it.

I assume from your post that you have a buttons in the WDA view and you are creating the FPM event based on that button action.

In that case , make sure that you fire the event as suggested by Chris.

IF you have the FPM buttons,instead of the wda view buttons , then you do not need these firing event. You can directly catch the event.

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,

Chris
