Hi Daniel,
I think, your Problem lies in PagedListDataModel<T>.getRowData() from wiki.
I've implemented this approach, however with my own DataScroller, based
on AjaxDataScroller by Adrian Mitev, and everything works fine.
Take a look at conditions for (re)fetching of single DataPage (I've
extended the original comments with my own).
// Check if rowIndex is equal to startRow,
// useful for dynamic sorting on pages
//
//comment: why should it be usefull???
//this duplicates fetch calls, if the page was
//already fetched in getPage().
//The same in if (rowIndex >= endRow)
//with condition 'or equal'!
if (rowIndex == page.getStartRow()){
_log.debug("Fetch: in getRowData(), reason: rowIndex ==
page.getStartRow()");
page = doFetchPage(rowIndex, pageSize);
}
regards,
paul

I really need help with this, nobody has implemented succesfuly the
datascroller + WorkingWithLargeTables article? How do you people
implement the pagination with a Tomahawk dataScroller, without bring
all the records? For me all works fine my problem is that the method
that brings the data is call several times for each DataPage.
