Hi Daniel,
look at this:
public DataPage<Paciente> fetchPage(int startRow, int pageSize) {
return getDataPage(startRow, pageSize);
}
if you make sure you call getDataPage only once for any given
startRow/pageSize, you'll be save - so you need some caching there.
regards,
Martin

Since everything works fine, I think that the problem is in the JSP
t:dataScroller and t:dataTable properties, something is calling the backing
bean several times (the fetchPage), I'm new in this, can anyone check the
JSP and see if I´m doing something wrong on it causing the multiple calls?

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.
