Dump when switching to a different variant

[Former Member]

Hi all,

I am a freshman for FPM, and currently I have met a issue when using it.

You know I want to switch to a different variant, but when I click the switch button, dump occurs:

Note

The followin error text was processed in SD7 the systm: Access via 'NULL' object reference not possible.

The error occurred on the application server ldai1sd7_SD7_89 and in the work process. 9

It ever worked fine before, and I have never changed my codes these days. Moreover, in some other development system

with old versions, the same codes can also work without any dump.

Has anyone met similar problems? I will appreciate your kindly help for any suggestions on this issue.

Thanks.

Hi

I have exactly the same problem.

I had implemented a switch between version using the overwrite_event_gaf, and a restart of the application with the use of cl_fpm_event=>gc_event_start_over.

Evereything worked fine till we made the upgrade from 701 to 720.

Then every time the FPM got restarted AND the customizing version switched, the already mentioned dump occures in the cnr_view of the FPM_GAF_COMPONt (to be exact; in the line 291 because the used object road_map_step ist initial)

I would apreciate any info concerning this.

The plog mentioned before only shows the way i already have done it.

The restard i mentioned in my last post doesn't influence the problem. The dump occures every time the version gets shwitched, even if there was no restart before!

In the OVERRIDE_EVENT_GAF i use the following code to change the variant:

TRY.

CALL METHOD io_gaf->set_variant

EXPORTING

iv_variant_id = 'VARIANT_3'.

CATCH cx_fpm_floorplan .

ENDTRY.

Hello everyone

The problem now has been solved by a new created note 1648280. (Thanks to Jinchi Lu

)

Hi Alex,

What code you have written to switch variant.

I hope you have implimented IF_FPM_GAF_CONF_EXIT/IF_FPM_OIF_CONF_EXIT and

using the method OVERRIDE_EVENT_GAF/OVERRIDE_EVENT_OIF (in that you would have class IF_FPM_GAF which has the relavant methods) to switch the variant.

give us code if possible.

Thanks & Regards,

Hi Arvind,

Thank you very much for your reply.

Yes, I have implemented OVERRIDE_EVENT_GAF.

Here is my related codes:

-

---

method OVERRIDE_EVENT_GAF .

DATA: lr_pfm TYPE REF TO if_fpm.

TRY .

CASE io_gaf->mo_event->mv_event_id.

WHEN if_fpm_constants=>gc_event-start.

CASE WD_THIS->AV_VARIANT_TYPE.

WHEN 'A'.

io_gaf->set_variant( iv_variant_id = 'VARIANT_1' ).

WHEN 'B'.

io_gaf->set_variant( iv_variant_id = 'VARIANT_2' ).

WHEN OTHERS.

io_gaf->set_variant( iv_variant_id = 'VARIANT_2' ).

ENDCASE.

WHEN 'GO_V1'.

lr_pfm = wd_this->ar_fpm.

lr_pfm->raise_event_by_id( if_fpm_constants=>gc_event-start ).

• lr_pfm->raise_event_by_id( cl_fpm_event=>gc_event_select_variant ).

WD_THIS->AV_VARIANT_TYPE = 'A'.

WHEN 'GO_V2'.

lr_pfm = wd_this->ar_fpm.

lr_pfm->raise_event_by_id( if_fpm_constants=>gc_event-start ).

WD_THIS->AV_VARIANT_TYPE = 'B'.

WHEN OTHERS.

ENDCASE.

CATCH cx_fpm_floorplan.

ENDTRY.

endmethod.

Hi Alex,

I tested te same code on my PC and it is working fine.

Did you check carfully, you might be getting the the dump from somewhere else( not because of FPM).

still, go to component config and check the Variant Id (Click on change button->Variant Parameters).

and if possible from ST22 give me the source code for line of dump and also check the Desktop 2, while debugging,

to check the method of your application from where the dump is coming.

Thanks & Regards,

Hi Arvind,

Thank you for your reply.

In fact my codes also works in the other system, but just in the current system, the dump occurs suddenly these days.

It ever worked normally before.

Here is the debugging information:

Is it enough for your analysis?

Hi Arvind,

The dump occurs in the following place:

road_map_step = cl_wd_road_map_step=>new_road_map_step( view = view description = lv_name

id = lv_tmp_rop_id ).

road_map->add_step( road_map_step ).

ELSE.

road_map_step = road_map->get_step( id = lv_tmp_rop_id ).

ENDIF.

road_map_step->set_name( lv_roadmap_int ). ##########Dump occurs because road_map_step is initial#########

road_map_step->set_enabled( lv_mainstep_enabled ).

• Create Roadmap Context Element and bind it to the UI-Element

lo_el_rop_data = lo_nd_rop_data->create_element( ).

lo_el_rop_data->set_attribute( EXPORTING name = 'ID' value = road_map_step->id ).

These days I checked this problem again, and I find that the dump is caused because the internal implementation for

WDDOMODIFYVIEW() in CNR_VIEW of FPM_GAF_COMPONENT has been modified in the latest version. It has made it

impossible to raise the CL_FPM_EVENT=>START directly by users.

However, I am still confused on how to restart my FPM application after setting a new variant ID. I ever tried the FPM_

NAVIGATION_TO API, but got errors like "No launchpad entry"....

I will appreciate for any ideas on this problem

Thanks.

Best Regards,

Alex
