a bug in the didSelectItemAtIndexPath

[qimuya3]

like this:

• (void) collectionView:(PMBrowsingCollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
  {
  NSInteger r = indexPath.row;
  NSInteger sec = indexPath.section;
  NSInteger item = indexPath.item;
  DLog(@"Selected item at %@", indexPath);
  }

Question is : the variable sec is always is 0, although I touch in the section 2,3 .....;
