Cristian Bogdan commented on HHH-3300:
--------------------------------------
to make this work, i did something like
[SELECT it.project.color AS col1 FROM projman.Deficienta def JOIN def.item it WHEREexists
(FROM projman.Project proj, projman.Principal grp JOIN grp.groupMembers p WHERE
proj=it.project AND p=:principal AND grp.displayName='Beneficiar' AND grp in
elements(proj.participants))
)) ORDER BY it.end]
HQL looks for property in wrong class and reports "could not
resolve property"
------------------------------------------------------------------------------
Key: HHH-3300
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3300
Project: Hibernate3
Issue Type: Bug
Components: query-hql
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6.ga, mysql 5.0.37
Reporter: Cristian Bogdan
could not resolve property: groupMembers of: projman.Project
[SELECT it.project.color AS col1 FROM projman.Deficienta def JOIN def.item it WHERE
exists (FROM it.project.participants grp JOIN grp.groupMembers p WHERE p=:principal )
)) ORDER BY it.end]
the problem is, groupMembers is not a property of projman.Project, but a bag in
projman,Principal.
as soon as I replace the it.project.color projection with e.g. it.start (i.e. i don't
make any other join with projman.Project), the query works.
the original query is actually more complicated but i reduced my test to the above for
simplicity. rewriting the query without subqueries is not an option.
i paste the relevant (generated) mappings.
