Can I map foreign key and add additional conditions?
For example: If I have two objects: Parent, Son. Son has "active" column. I want to map between the parent and the active sons only:

Code:

 <set
        name="sons"
        lazy="true"
        inverse="true"
        cascade="all-delete-orphan"
    >
        <key>
            <column name="parent_id" />
        </key>
        <one-to-many 
            class="com.xxx.Son"
        />
    </set>  

Is there some property that I can add to get only the active sons?

Thanks.

Hello,

I'm not very sure, but that url would be useful (I hope so)

You can also add a where attribute in set tag to filter the elements in collection.

Go through this link.
