How to build a tabular form with a by the user insertable primary key

Question

I have build a build a tabular form with the wizzard. Wat should I do to make the primary key insertable by the user.
When I change the PK from 'hidden' to 'text field', I get a checksum error when i am trying to insert.

Fred: When you use the tabular form wizard, notice the help text on the right hand side of each page. The help page where you define the type of primary key (Existing trigger, PL/SQL function, existing sequence) clearly states
Tabular forms do not support user entered primary key values
Makes sense when you think about it. The MRU process needs to determine whether to update a record or insert a new record. It does that by comparing the checksums (and/or) pk values from when the page was first rendered and then when you make changes and submit it. Newly inserted rows will have a blank PK/checksum.
If you allow user to change the PK, how will the system know which rows are new and which ones are old?
For example, lets say you have
create table t
pk int primary key,
data varchar2(10)
)You have 2 rows
1 red
2 yellow
If the PK were to be editable, user could go in and change the above to
2 red
1 yellow
Now what? Would you like the system to create a new row with 1/yellow or change the existing pk=1 row to yellow? Same with the other row.
Bottom line: The built-in processes dont support this. You can always write your own manual tabular form and implement whatever you logic you wish in your After Submit processes.
Hope this helps.
