What does that mean...? I've been debugging for a while, and I've no clue what's wrong...

Here's what I have for the DaoImpl:

Code:
	public List getTopicByForumId(String forum_id) {
        String query = "from TopicModel topic where topic.forum_id = ?";
        return getHibernateTemplate().find(query, forum_id);
	}
most likely that there's something wrong with that...
topic_id is only defined by the Hibernate as the foreign key to the ForumModel's forum_id...

It seems like that's because forum_id is not the property defined in the TopicModel, and it throws this exception.. But, how do we access (TopicModel in the database it's called "topic") and generate list of those topics based on the forum_id, in which in this case is referenced from the ForumModel class in the hibernate...
