Can I have a collection of different types? My
situation is as follow: an Order has many LineItems,
however LineItem class is abstract with 2 different
subclasses: ConcreteLineItem1, ConcreteLineItem2
I have tables for each: Order, LineItem,
ConcreteLineItem1 and ConcreteLineItem2
Originally my Order mapping looked like this:
<field name="lineItems" type="LineItem"
collection="collection">
<sql many-key="order"/>
</field>
however this tries to instantiate LineItem object
which is abstract :(
Is there an easy way to load lineItems collection from
both concrete tables?
Thanks,
Krzysztof
