If we do add an exception we will be on the other side of the fence, the
user now HAS to handle it. Personally, I wouldn't want to have a try catch
block everytime I have a dataview for something that can be handled for me
automatically. What else would you do inside that catch block other then
redirect to first or last page?
Last time I checked setStartIndex() is public so you are more then welcome
to override it.
Public setStartIndex(int index) {
if (index<0||index>==getItemCount()) {
throw new IndexOutOfBoundsException();
}
super.setStartIndex(index);
}
