New error regarding sublcass Conference Poster

[fur...@gmail.com]

Have not seen this one before....

Error message

ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'ConferencePoster'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Work.inheritance_column to use another column for that information.

This sounds familiar, but I'm away from the code at the moment. It might be as simple as checking (proper_?)work_subclasses directory under app/models to make sure there's a conference_poster class file there.
