actually everything just fine if i put
rowList:[],
to disable the rowlist select box.
and the server should response no problem with different rowNum: value
it maybe a bug because when i change the rowlist say from 20 to 30. it work but just the select box sync function doesn't. however if i keep going and click next page or something else like fresh then works, 100%
also after i change the rowlist selection sometimes it work(i mean only the select sync) and sometimes it doesn't, sometimes when i change from 10 to 20. only the first 10 is selected and the rest are not. for sure if i click next/prev page it then work fine until i change the rowlist again.
