I have an Oracle Application Server (10g) package that basically displays rows of data that users can edit after clicking an edit button. The edit page contains 1 to 20 text fields. It was working great using owa_util.ident_arr until the users needed to insert more than the ident_arr varchar2(30) character limit.
Now that I can't use ident_arr, I am trying to figure out how to insert the contents of the text areas (htp.formtextareaopen) into a table. As I said, the edit page can have 1 to 20 text fields in it.
Without knowing more about your implementation I should say you need to create your own collection type. First check from the documentation what owa_util.ident_arr really is:
type ident_arr is table of varchar2(30) index by binary_integer;
What you need to do is then create your own collection with a table of varchar2:s greater then 30 as e.g.
type my_arr is table of varchar2(255) index by binary_integer;
