Hi, I have Class Employee and class EmployeeRootParam. they are in many to many relationship. EmployeeRootParam has ParamType class with boolean member name enabled and userViewRight as Integer.

I try to find all the EmployeeRootParam that has ParamType.enabled equal true and userViewRight greater than 2.
I use the query as follow:

Criteria paramCriteria = HibernateSessionFilter.getSession().createCriteria(EmployeeRootParam.class);

paramCriteria.add( Restrictions.eq("paramType.enabled", Boolean.TRUE))
.add( Restrictions.gt("paramType.userViewRight", ParamType.ADMIN_ONLY_VIEW_RIGHT))
.addOrder( Order.asc("paramType.priority"));


Criteria empCriteria = paramCriteria.createCriteria("supportedEmployees")
.add( Restrictions.eq("id", getEmployee().getId() ) );

res = paramCriteria.list();


I get the foolowing exception:
javax.faces.el.EvaluationException: javax.faces.el.EvaluationException: Error getting property 'employeeTab
le' from bean of type com.gemInfo.cp.webapp.beans.EmployeeBean: org.hibernate.QueryException: could not res

What is wrong? Thanks in advance for your help

You need to use an alias to get at nested values.

Thanks, it works.
