I got the next code:

public function getProductCollection()
    if (isset($this->_productCollections[$this->getCurrentCategory()->getId()])) {
        $collection = $this->_productCollections[$this->getCurrentCategory()->getId()];
    } else {
        $collection = $this->collectionProvider->getCollection($this->getCurrentCategory());
        $this->_productCollections[$this->getCurrentCategory()->getId()] = $collection;
    echo "Collection count".$collection->count();
    return $collection;

When I tried to echo collection count - it always equals 0, but when I delete this string - everything is okay count equals 16. How?


I think you are supposed to append the string in the return

//echo "Collection count".$collection->count();
return "Collection count ".$collection;
