[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2172) Could not determine fecht owner exception with 3.2.0GA (worked in 3.2rc2)

[Alexander Rupsch (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2172?page=comments#action_25866 ] 

Alexander Rupsch commented on HHH-2172:
---------------------------------------

The problem is solved, it seems that hibernate 3.2.xGA pays attention to the order of the return-join and the return-alias tags.

this works:

<return alias="goe" class="com.ecg.mts.tsm.impl.domain.MasterDataEdge"/> 
<return-join alias="child" property="goe.child"/>

this does not:

<return-join alias="child" property="goe.child"/>
<return alias="goe" class="com.ecg.mts.tsm.impl.domain.MasterDataEdge"/> 


Well, interesting change. You can close the issue. 

kind regards
