Re: Using pagination inside elements

Some progress: adding the paginator helper to the helpers array avoid
the "call to a memeber function in a non-object", but the paginator
doesn't paginate anything. In each helper call an undefined index
error is shown.

Notice (8): Undefined index: pageCount [CORE\cake\libs\view\helpers
\paginator.php, line 476]
Notice (8): Undefined index: count [CORE\cake\libs\view\helpers
\paginator.php, line 416]
...

Any idea?

Note that the paginator helper must be added to the items controller,
not the item_comments controller.
