Hallo,

ich versuche mich mit einer HQL-Abfrage an einem Assoziationspfad in meinem Objektgeflecht entlang zu hangeln:
Code:
select adresssatz    
from    de.foursoft.migrationworks.domain.Fall as fall    
where    fall.adresssaetze.ersterAdresssatzteil.si__ZUNAME='Meier1'

Leider bekomme ich folgende Fehlermeldung:
Code:
java.lang.RuntimeException: Error performing 'de.foursoft.migrationworks.domain.FallDao.findByCriteria(de.foursoft.migrationworks.vo.FallSearchCriteria criteria)' --> org.hibernate.QueryException: illegal attempt to dereference collection [fallimpl0_.ID.adresssaetze] with element property reference [ersterAdresssatzteil] [select adresssatz    from    de.foursoft.migrationworks.domain.FallImpl as fall    where    fall.adresssaetze.ersterAdresssatzteil.si__ZUNAME='Meier1' ]
   at de.foursoft.migrationworks.domain.FallDaoBase.findByCriteria(FallDaoBase.java:316)
   ...


Eigentlich sollte das doch ein ziemlich normaler Anwendungsfall für HQL sein. Wie formuliert man eine solche Abfrage in HQL?

Vielen Dank
