Hi,

when i fetch a non existing node by path like

fetch('content', 'node', hash('node_path', 'Media/not/existing/node'))

it get a warning while fetching a non existing node by id like

fetch('content', 'node', hash('node_id', 99999))

returns just false() without any errors/warnings. Its because the function eZURLAliasML::fetchNodeIDByPath in eZContentFunctionCollection::fetchContentNode returns false and this is passed unchecked to eZContentObjectTreeNode::fetch.

Steps to reproduce

fetch('content', 'node', hash('node_path', 'Media/not/existing/node'))
fetch('content', 'node', hash('node_id', 99999))
