> Hi again,
> I try to implement a paged resultset using the firstResult and maxResults method of the
Query class. It seems that this is not working as expected. 
> Here is the relevant part of the logging.
> DEBUG,Query,main] Executing query: select s from SimpleEntity s order by s.id
> [DEBUG,SQL,main] <t 2132679615, conn 651497704> executing prepstmnt 558185842 SELECT
LIMIT 0 2 t0.id, t0.version, t0.base, t0.street, t0.my_name FROM some_objects t0 ORDER BY
t0.id ASC
> [DEBUG,Query,main] Executing query: select s from SimpleEntity s order by s.id
> [DEBUG,SQL,main] <t 2132679615, conn 651497704> executing prepstmnt 2094184728
SELECT LIMIT 0 2 t0.id, t0.version, t0.base, t0.street, t0.my_name FROM some_objects t0 ORDER
BY t0.id ASC
> Both queries are identical. So my guess is once more the trouble comes from the query
cache.
