Is it possible to populate list item in TAB CANVAS

Question

Hi,
I have two datablock first is master and second is detail (master detail block) I want to populate second datablock fields on the basis of first data block selection (second block is displayed on Tabuler or Grid like canvas) I made list item type data fields on second or Tabuler canvas(detail block) and want to populate this list at run time on WHEN-NEW-BLOCK-INSTANCE trigger, is it possible, if yes what's wrong I am doing because this list population works fine on master block
(master block with canvas type of FORM).
Thanks and Regards.

Hi,
Fifty percent of my problem is solved second canvas list item values now populated successfully, but another problem is that it populates when I click second time on a required button, the button and queried items are in same datablock
the code behind the WHEN-BUTTON-PRESSED trigger button is:
declare
     exist_chk number:= 0;
begin
     select count(*) into exist_chk
     from incident
     where ref_no = :incident.ref_no
     and inc_type_code = :incident.inc_type_code;
     IF exist_chk <> 0
          THEN
SET_RECORD_PROPERTY(:system.cursor_record,'INCIDENT',status,new_status);
Set_Block_Property('INTERP_DETAIL', ONETIME_WHERE, ' WHERE ref_no ='||:incident.ref_no||' and inc_type_code='||''''||:incident.inc_type_code||'''');
execute_query;
else
display_message('msgbox_stop','No Master Data','First Enter Master Record ');
     end if;
end;
