the following line
subList = ((List)items).subList(offset, limit);

generates an exception
java.lang.IllegalArgumentException: fromIndex(4) > toIndex(2)

if offset is larger than limit.

FIX:

---

public Collection getPageItems() {

Collection subList = items;
int offset = getOffset();
if(count > 0) {
int limit = maxResultsPerPage + offset;
if(items.size() < limit)

{ limit = count; }

if(offset < limit)

{ subList = ((List)items).subList(offset, limit); }

else

{ subList = items; }

}
return subList;
}

This error happens if the GET Parameter currentPage is set (for example from an old session or an old link), but there are not enought items in the current Collection.
