Insert a new record in the middle of a tabular form

Question

Hi,
I have a tabular form.
Pressing "Add Row" button opens a new, empty row at the bottom of the page or - if I use pagination - jumps to the page with the last record and creates a new record there.
Is it possible to open a new line in the middle of the page ?
I mean: if I have 25 records, I am on the first page (records 1-10) and the cursor is in a field of the second record and I press the "Add Row" button there should be a new, empty second line with old second record in the third line,... the old ninth record now in line 10 and disappeared record ten ?
Any idea ?
Thanks,
Heinz

Heinz,
You may investigate logic using UNIONs and a manual tabular form.
Something like:
--get all records above new row
select apex_item... column1
,apex_item... column2
from yourtable
where <logic to limit rows above new record>
union
--get the new row
select apex_item... column1
,apex_item... column2
from dual
where :REQUEST = 'ADDROW'
union
--get every row not in the top query
select apex_item... column1
,apex_item... column2
from yourtable
where <logic to pull all records not pulled above new record>
For this to work you'll need to add your own "Add Row" button and associate it with a branch. Notice the select between the two unions in the above query is a select against dual. This will be your new record when pressing your "Add Row" button (:REQUEST = 'ADDROW').
The following how-to link is a reference for some of the logic you'll need when creating a manual tabular form.
