Pagination not working using display tag

Question

I'm using display tag to display my result set. Here's how I implement it.

<display:table name="w" pagesize="10"  export="true" />

Here I've set pagesize =10 and when I run the app , the records are paged to size 10 but when I click on the next page to view the next set of records, I get an empty result set.

E.g if there are 12 records, 10 of them are displayed in the first page and when I click on next to view the last page, I get an empty page. Why is this happening??

w contains a list of all my records :

request.setAttribute("w", resultrechparcritere);

The table must be able to contact the Action when handling the pagination,

then you have to include requestURI, along with (the not-mandatory fields, if I remember well) keepStatus and uid:

<display:table requestURI = "myActionURL" 
               keepStatus = "true" 
                 pagesize = "10"  
                     name = "w" 
                      uid = "myTable" 
                   export = "true" />

Then, you can even intercept and tweak / hack the pagination parameters by yourself, to programmatically reach a specific page.
