SimplePager strange row count

I'm encountering a problem with SimplePager; the problem is that when I clic to display the next page of rows the indicator of rows number multiply by two (for example initially I have to display 30 rows, initially the pager displays " 1-8 of 30 " However, when I clic to display the next page the indicator displays " 9-16 of 60 ")

By the way to display the pager I defined it on UiBinder file and I did this :

simplePager.setDisplay(cellList);
开发者_Python百科    verticalPanel.add(simplePager);
    verticalPanel.add(cellList);

Any help are welcome.

Thanks.

I guess you're probally adding the same elements to the list you're trying to page.

Check the data loading into the grid or table you're trying to page.
