Native SQL return-property mapping doesn't support dot-syntax in return-property for components ----------------------------------------------------------------------------------------------- Key: HHH-1019 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1019 Project: Hibernate Core Issue Type: Improvement Components: core Reporter: Christian Bauer Assignee: Emmanuel Bernard Priority: Blocker Fix For: 3.1.1 This is a SQL/SP mapping: <return-property name="billingAddress.street" column="BILLING_STREET"/> It refers to a property in a <join> table: <join table="BILLING_ADDRESS" optional="true"> <key column="USER_ID"/> <component name="billingAddress" class="Address"> <property name="street" type="string" column="STREET" length="255"/> ... Calling/loading with this SQL mapping fails, as Hibernate always tries to use "STREET" with the resultset instead of "BILLING_STREET".
