> 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.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
