SlotsInformation, has_portlets and show="False"

[pierreNomazy]

Try a category with only the Filter portlet in one portlet. Then look at one or many products of this category. The bug (offset in slot) cames from the function 'has_portlets' in
lfs-theme / lfs_theme / templatetags / lfs_theme_tags.py. In this case 'has_portlet' is True because parent of the product = category has one portlet, but the rendered of this portlet is empty with show="False" in the product.
To fix it, I suggest to remove 'has_portlet' by a new function : has_portlets_rendered
def has_portlets_rendered(obj, slot,context):
portlets_list = []
rendered_list = ''
while obj:
portlets_list = portlets.utils.get_portlets(obj, slot)
for p in portlets_list:
rendered_list = (''.join(p.render(context)))
if len(rendered_list.strip()) > 0:
return True
if portlets.utils.is_blocked(obj, slot):
break
try:
obj = obj.get_parent_for_portlets()
except AttributeError:
break

return False
