I use hibernate 1.0.2. I have such situation - I Have a class and it's child - joined-subclass and I need to create formula in childs property which uses property from parent class.
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="CoreIMSEE.Domain.Partner, CoreIMSEE.Domain" table="PARTNER">
<id name="Id" column="ID" unsaved-value="0" access="field.camelcase">
<generator class="native" />
</id>

<timestamp name="timestamp" column="TS" access="field"/>


<property name="Name" column="NAME" type="String" length="100" not-null="true" />

<joined-subclass name="CoreIMSEE.Domain.Customer, CoreIMSEE.Domain" table="CUSTOMER">
<key column="ID" />

<property name="Name2" column="NAME2" />
<property name="Name3" column="NAME3" />
<property name="customerName" formula="Name + ' ' + Name2 + ' ' + Name3" insert="false" update="false" type="String" access="field" />
</joined-subclass>

</class>

This formula is incorrect because in SQL I found that it uses alias from Customer table instead of Parent table alias so I got error. How can I solve this problem?

are you using that calculated property in a HQL query? if not, the simplest workaround is to not map that property at all. Simply do the "calculation" in the property getter of your object.

I use it to filter data and to sort data ny this field.
