Tabular forms getting ORA-0000 intermittently.
Temporary fix is to remove one of the fields.

Have a very small application that is using tabular forms to display and edit data. This small app did work fine initially, but ORA-0000 errors started to show up once users clicked on buttons that should navigate to a page with a tabular form.
Hiding one of the columns on the tabular form (Uncheck "Show"), allows the form to work okay for a while, then ORA-0000 error is thrown again. Have already hidden 3 columns from report, only 6 more columns do remain.

Here is another error that users are getting when Apex is generating tabular forms:

report error:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small

That is also addressed if one column is hidden. Then the page (tabular report) generates successfully again.
