is not mapped error from entity-query?

[jnusaira]

I was curious if anyone is getting the error below when running the entity query.

The weird thing is. It's kind of random. And i know the object is there because I have an EntityManager query called at startup to do some initialization

This is the basic definition of the page -

Not sure why but it seemed to start when we added a new column to the database, but I am guessing that is coincidence.

we are using Seam 2.0.2

<framework:entity-query name="matchingSchedules" 
                            ejbql="Select s From SubstanceJobSchedule s Where s.workStream = 'MATCHING' And s.customCron = false " 
                            entity-manager="#{entityManager}">    
        </framework:entity-query>                         
        <event type="org.jboss.seam.afterTransactionSuccess">
                <action execute="#{matchingSchedules.refresh}" />
        </event>

Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: SubstanceJobSchedule is not mapped [Select s From SubstanceJobSchedule s Where s.workStream = 'MATCHING' And s.customCron = false ]
