We have an application that contains a lot of pages (850 pages). Recently, we added a new tab in the shared component and since then, when we try to reach the page "Manage Tabs", this error appears :
Error Error during rendering of region "Tab List".
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
We tried to delete a couple of standard tabs but the error still appears. We tried to delete all our standard tabs as a test to see if we would be able to manage our tabs.
It worked, the error disappeared but we weren't able to see all the parents tabs because the region as the property overflow:hidden so no horizontal scrollbar is there to see the rest of our parents tabs.
We have 251 Standard tabs and 55 parent tabs, 69 tab sets. We're using APEX 4.1 but the error also appears on APEX 3.2.
