        Key: HBI-9
    Summary: Not being able to query using an object
       Type: Bug

     Status: Closed

Description:
I have two classes Event and Person and I want to query event based on a Person. I was hoping I would be able to do this:

String query = "from com.rhi.domain.impl.Event as event where event.person =?"

Since Event is related to Person by a many-to-one relationship I thought Hibernate could create the right sql from the above query.
        <many-to-one name="person" class="com.rhi.domain.impl.Person">
            <meta attribute="property-type">com.rhi.domain.Person</meta>
            <column name="person_id"/>
            <column name="person_region_id"/>
        </many-to-one>



But it didn't work and I had to do this:

String query = "from com.rhi.domain.impl.Event as event where event.personId = ? and event.personRegionId = ?";

and I also had to add separate mappings for the ids as such so that the query would work:

        <property name="personId" column="person_id" type="java.lang.Long"/>
        <property name="personRegionId" column="person_region_id" type="java.lang.Long"/>


I wasn't sure if this was a bug or a new feature. If this is a new feature are there plans to implement it?
