Jira issue originally created by user shurakai:
I think that for example the YamlDriver should throw an exception if the filename passed to _loadMappingFile() (e.g. by parent::preload()) does not end with .dcm.yml
Comment created by @beberlei:
preload() was removed for ALPHA4, aand is removed in trunk already. Are you using ALPHA 3?
Resolved in current implementation already.
Issue was closed with resolution "Fixed"
