Hi,
to avoid this issue, you have to override the
setPageStart(int index) method in the AbstractPager class.
with the following code:
/**
* Set the page start index.
*
* @param index the index
* @see #getPageStart()
*/
protected void setPageStart(int index) {
if (display != null) {
display.setVisibleRange(index,
display.getVisibleRange().getLength());
}
}
This code will set the startindex of the page as expected. But be
careful the size of the CellTable will be reduce, because you have
less rows!
