component in a component

Hi! i have a TimePeriod class, wich contains begin TimePoint, and end TimePoint. TimePoint class represents a single Date value.

I think id doesn't make sense, to map these classes as entities. I prefer to map them as value objects.

Unfortunatly, i get the following exeption: org.hibernate.QueryException: could not resolve property: end of: com.itcodex.objectpuzzle.party.domain.Person

(Person is a class wich has a TimePeriod association called valid)

I map it like this in Person.hbm.xml:

Code:

<component name="valid" class="com.itcodex.objectpuzzle.framework.fundamental_types.domain.TimePeriod">
         <component name="begin" class="com.itcodex.objectpuzzle.framework.fundamental_types.domain.TimePoint">
            <property name="value" column="BEGIN_VALUE" type="java.util.Date"></property>
         </component>

         <component name="end" class="com.itcodex.objectpuzzle.framework.fundamental_types.domain.TimePoint">
            <property name="value" column="END_VALUE" type="java.util.Date"></property>
         </component>
      </component>

Am i doing something wrong? thanks.

1) What is the query you used?
2) The error does not seem to speak about the component, but about the Person class itself, that's why I think there's a problem in the way you're querying.

Hi!

The query is:

from Person p where p.valid.end is not null and p.valid.end.value >= current_date()) or (p.valid.end is null) ) and p.valid.begin.value <= current_date()
