IG query is

select
 seq_id seq_id,
 c001 c001,
 c002 c002
from apex_collections
where collection_name = 'IG'

SEQ_ID: Display Only, Primary Key = Yes, Query Only = No

IG Save uses custom PL/SQL code

if (not (apex_collection.collection_exists('IG')))
 then apex_collection.create_collection('IG');
end if;
    
case :apex$row_status
        when 'C' then
               apex_collection.add_member(
                    p_collection_name => 'IG',
                    p_c001           =>  :C001,
                    p_c002  => :C002
               );
        when 'U' then
               apex_collection.update_member(
                    p_collection_name => 'IG',
                    p_seq             => :SEQ_ID,
                    p_c001           =>  :C001,
                    p_c002           => :C002  
               );
        when 'D' then
               apex_collection.delete_member(
                    p_collection_name => 'IG',
                    p_seq             => :SEQ_ID
               );
        end case;

I am seeing behavior I can't explain.

1. Click Add Row
2. Enter values for C001 and C002
3. Click Save
4. Change are saved successfully but the IG does't refresh to show the newly added row.
5. Click Go and now the new row shows up fine

Any ideas?
