Description

In certain cases the Fast forward works incorrectly, resulting in an empty table.
For instance you have 100 rows, 10 per page, fastforward set to 10.
You start off on the first page, then fast forward.

Due to a little bug in the page calculation, you will end up on page 11, which is empty.

Proposed fix:
snip from HtmlDataScroller broadcast – see the line commented with //fix here

else if (FACET_FAST_FORWARD.equals(facet))

{ int fastStep = getFastStep(); if (fastStep <= 0) fastStep = 1; int next = uiData.getFirst() + uiData.getRows() * fastStep; int rowcount = uiData.getRowCount(); if (next >= rowcount) //fix here >= instead of > next = (rowcount - 1) - ((rowcount - 1) % uiData.getRows()); setFirst(uiData, next); }
