I've discovered the view method renderElement, that has a parameter
called loadHelpers, false but default, that looked good.
But it doesn't work. The paginator helper isn't loaded and I'm getting
the same odd undefined indexes notices.
The renderElement method isn't properly explained neither in the doc
or the api, so I don't know if it's useful, deprecated or whatever.
If i can't use the paginator inside an element, I think is far away
from the shining proclamed in the doc :(
