I encountered the same problem :-(
What's more ominous is that the change in visibleRange also causes a
second onRangeChange event (which is undesirable if nothing else): (1)
For the initial page forward to the last page (with potential unequal
number of rows to pageSize) and (2) For the re-rendering of the last
page with visibleRange set to show pageSize rows but indexed from
display.getRowCount() - pageSize (as noted by OP).
I found a fix however, by overriding setPageStart in SimplePager, as
follows:-
public void setPageStart(int index) {
if ( getDisplay() != null ) {
Range range = getDisplay().getVisibleRange();
int pageSize = range.getLength();
if ( isRangeLimited()
&& getDisplay().isRowCountExact() ) {
pageSize = Math.min( pageSize,
getDisplay().getRowCount()
- index );
}
index = Math.max( 0,
index );
if ( index != range.getStart() ) {
getDisplay().setVisibleRange( index,
pageSize );
}
}
}
This shows the last page with a number of rows less than pageSize if
getRowCount() is less than pageSize * numberOfPages.
I hope it is of use.
Cheers,
Mike
