[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-5370) Building IN condition with CriteriaBuilder providing collection of values not working.

Building IN condition with CriteriaBuilder providing collection of values not working. -------------------------------------------------------------------------------------- Key: HHH-5370 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5370 Project: Hibernate Core Issue Type: Bug Components: entity-manager, query-criteria Affects Versions: 3.5.3 Reporter: bogdan Assignee: Steve Ebersole Fix For: 3.5.x, 3.6 Building IN condition with CriteriaBuilder providing collection of values not working. Given: Join<CommissionPo, AreaPo> ca; List<Long> unitAreaIds; calling ca.get(AreaPo_.id).in(unitAreaIds); ends with: java.lang.IllegalArgumentException: Unaware how to convert value [[1006, 1008, 1009, 1013, 1011, 1010, 1012] : java.util.ArrayList] to requested type [java.lang.Long] at org.hibernate.ejb.criteria.ValueHandlerFactory.unknownConversion(ValueHandlerFactory.java:259) at org.hibernate.ejb.criteria.ValueHandlerFactory.access$000(ValueHandlerFactory.java:35) at org.hibernate.ejb.criteria.ValueHandlerFactory$LongValueHandler.convert(ValueHandlerFactory.java:153) at org.hibernate.ejb.criteria.ValueHandlerFactory$LongValueHandler.convert(ValueHandlerFactory.java:140) at org.hibernate.ejb.criteria.predicate.InPredicate.<init>(InPredicate.java:126) at org.hibernate.ejb.criteria.predicate.InPredicate.<init>(InPredicate.java:105) at org.hibernate.ejb.criteria.CriteriaBuilderImpl.in(CriteriaBuilderImpl.java:577) at org.hibernate.ejb.criteria.expression.ExpressionImpl.in(ExpressionImpl.java:91) as a workaround we can call: ca.get(AreaPo_.id).in(unitAreaIds.toArray()); Cause (varargs missuse): org.hibernate.ejb.criteria.expression.ExpressionImpl.in(Collection<?>) calls org.hibernate.ejb.criteria.CriteriaBuilderImpl.in(Expression<? extends Object>, Object...) as result whole collection from ExpressionImpl goas as single parameter to CriteriaBuilderImpl.in
