> I've found a problem in method getPageNavigationBar(Href, String).
> The problem is calculationg the startPage. Here is an example that fails
> (you could find many more, try changing groupSize to 5 ;-):
> groupSize=8
> currentPage=9
> fullListSize=224
> pageCount=12
> pageSize=20
> startPage should be 5 and was 4 (we could never see page 12)
> with this path we can
> The current version:
> startPage = Math.max(Math.min(this.currentPage - groupSize / 2,
> this.pageCount - groupSize), 1);
> endPage = Math.min(startPage + groupSize - 1, this.pageCount);
> The pathed one:
> startPage = Math.max(Math.min(this.currentPage - groupSize / 2,
> this.pageCount - groupSize), 1);
> //patch
> if (this.pageCount - this.currentPage < groupSize/2 + (groupSize%2>0?1:0))
> startPage++;
> //end patch
> endPage = Math.min(startPage + groupSize - 1, this.pageCount);
