When you say it doesn't paginate, do you mean you always have the full number of results returned, or you only ever get the first page?
Is your PHP code limiting the amount of records it returns? Because this must be done server side.
For me base toolbar appeared but pagination is not working, It displays all the rendered data in one stroke. When I click next it goes to next page but again the contents are same, i.e all the data rendered in single stroke...
I have specified pageSize: 10 but all the pages (26 pages) are displaying all the 254 records.
