Hi,
I am tring to use a variable for *pageSize* to work in
the *paging* attribute of the datagrid but can't get
it to work. I am attaching my code for your perusal.
Could you please see where I am doing wrong in the
code?
I declared a scope variable
-- int pageSize = 2;
which I used in
<paging size="${pageSize}"
nextUrlVar="next" previousUrlVar="previous"
pagesVar="pages"/>
It is working if I do this way: <paging size="2"
nextUrlVar="next" previousUrlVar="previous"
pagesVar="pages"/>
My actualy intention is to let the user choose the
pageSize in the form he submits to get to this results
page.
I would appreciate any help on this.
Thanks,
-Siva
