Bug? - Getting "ORA-20001: Unable to create updateable report"

Question

We have created hundreds of simple tabular reports, but have come across 3 tables that we cannot get past the following error for when finishing the last step of the create wizard:
ORA-20001: Unable to create updateable report. ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Error creating tabular form.
Return to application.
Here is the DDL for this table:
CREATE TABLE ancfx_test
(ANCFX_ID NUMBER(31,0) NOT NULL ENABLE,
APP_DTL_LVL_CD VARCHAR2(160),
NOTE_CALL_FR_TYP_CD VARCHAR2(15),
ANCFX_VOID_IND CHAR(1) DEFAULT 'n' NOT NULL ENABLE,
PCT_AUDT_USER_CREA VARCHAR2(30) DEFAULT 'PCT',
PCT_AUDT_DTM TIMESTAMP (6) DEFAULT SYSDATE
I have tried an alternate surrogate key, renaming the table, excluding the 160 character column etc., but not able to create this form.
Based on this and the many hundreds of unique tabular forms we have created, seems we may have run across a bug?
Any help would be greatly appreciated.
Thanks!

Hi Scott,
Turns out we did reach some sort of limit in APEX regarding how many pages can be assigned to a tab as the current tab for assigned pages. We had around 750 or more pages listed under a given tab as the current tab for those pages, which apparently created a list of page numbers in a string presumably that exceeded the maximum size for a field somewhere in APEX apparently, thus the error about the character buffer being too small. Not only could we not create new pages, but we could not even view the tab page in the shared components area for this tab without getting the error, but could get into the tab page to view the page numbers assigned to the tab.
To get around this we had to remove all the page numbers that were listed for the tab as the current tab for those pages. Once that was done, everything was back to normal, although the tab in question is no longer shown as the current tab for any of those pages, which is not really a problem for us.
Anyway, seems Oracle may want to review any field limits that are related to page numbers assigned to a tab to be the current tab for those pages and consider doubling that limit. In our case, 785 pages were too many for this limit, and there were no messages that helped us deduce where this was coming from - just brute force trial and error to figure this one out. Since we have more pages to go, we might run into some limits elsewhere which I'll post here if so.
