Custom pager for plsql service

We would like to provide the GET requests based on the results of a stored procedure (Source Type = PL/SQL)

i can understand that the automatic Pagination Size will not work in this scenario. Any ideas how to implement this?

BTW: I created a :pagesize parameter (querystring) and this works nicely.

A parameter :limit does not work, I guess that is reserved.

Cheers, Joep
