Hi,

eZDatatype:

function productOptionInformation( $objectAttribute, $optionID, $productItem )

kernel\classes\ezproductcollectionitem.php

eZProductCollectionItem::calculatePriceWithOptions
Line 234:
$optionData = $dataType->productOptionInformation( $objectAttribute, $option->attribute( 'option_item_id' ), $this, $option );

productOptionInformation allows only 3 params, but eZProductCollectionItem::calculatePriceWithOptions uses 4.

Also ez 4.0.x is affected.

Best wishes,
Georg.
