Large Select List fails with ORA-6502

Question

Creating a large select list with htmldb_item.select_list_from_query_xl causes an ORA-6502 when the resulting select list contents are larger than an arbitrary value.
For example, if the query for the select list returns a display value of up to 50 characters and a numeric id return value of up to 10 digits, we have to arbitrarily include "where rownum < x" (where x is some arbitrary value) in the query to get results; otherwise when the page is run we get the ORA-6502.
For regular select lists with long results we can get around the problem using htmldb_item.popup_list_from_query but to generate multiselect lists we have to use the htmldb_item.select_list_from_query_xl an include the attribute "multiple".

Answer 1

Can we get that added to the API documentation? The spec simply states the function returns a CLOB, implying that it would support the max size of a CLOB supported by the database (4GB in 9iR2 as I recall).
Granted, one should not expect a 4GB web page to be returned using the function call, but a page larger than 32KB isn't entirely unreasonable, especially since this product is geared towards intranet and departmental apps (ie corporate LAN environment).
An alternative enhancement would be to implement multiselects via the popup list mechanism, allowing users to select multiple items as they "page" or search thru the values for that field.
