Summary:
Trouble with breadcrumb in detail page
Detailed Description:
with différent levels of hierarchy, when we are on the detail page of an itel in
the last hierarchy level, the breadcrumb doesn't  print the right hierarchy of
the item. it prints the différents first levels.

example:
 we have 4 levels: 'level1', 'level2', 'level3', 'level4'
we have 2 sub-levels in each level: 'sublevel1.1', 'sublevel1.2',
'sublevel2.1', 'sublevel2.2'....
we have 2 last-levels in each sub-level: 'lastlevel1.1.1', 'lastlevel1.1.2',
'lastlevel1.2.1'...

for an item witch is in 'lastlevel1.1.2', the breadcrumb prints:

Breadcrumb: level1 > level2 > level3

instead of:

Breadcrumb: level1 > sublevel1. > lastlevel1.1.2

Seems like a confusion between id & item_order into get_hierarchy_path function

I fixed it by replacing lines 95-100 of class.hierarchy_ops.php : 

$breadcrumbs = array();
    foreach($tmp as $one)
      {
	$breadcrumbs[] = (int)$one;
      }
    return $breadcrumbs;

become :

$breadcrumbs = array();
    $db = cmsms()->GetDb();
	$prev_one = -1 ;
	foreach($tmp as $one)
     {
		  $query = 'SELECT * FROM '.cms_db_prefix().'module_products_hierarchy
               WHERE parent_id = ? AND item_order = ?';
    	$row = $db->GetRow($query,array($prev_one, $one * 1));
		if ( $row )
		{
			$breadcrumbs[] = $row["id"];
		}
		$prev_one = $one * 1 ;
    }
    return $breadcrumbs;

Your fix works with two levels but not with 3 or more!

I can confirm this bug.

Created a hierarchy like:

- Main
-- Sub 1
-- Sub 2
-- Sub 3

I added 3 products one,two,tree

On the detailview.

product "one" shows "Main >> Main" as breadcrumb <------------ weird the first
product is assigned to the second level "--Sub 1"
product "two" shows "Main >> Sub 2" as breadcrumb
product "one" shows "Main >> Sub 3" as breadcrumb
