Julien HENRY commented on HHH-1570:
-----------------------------------

Problem is still here with Hibernate 3.5 and 3.6. Both with hibernate and JPA 2 criteria APIs.

> We have a class Price that has a composite-id using a couple of key-properties and some key-many-to-ones)
> One of those is "transportation", which has a many-to-one to transportationType
> When we query using: criteria.add(Expression.eq("price.transportation.transportationType.id", transId);, we get an invalid SQL statement: The table of transportation was not selected.
> I will try to make a testcase today or tomorrow, depending on my schedule.. Things will be more clear by then...
> We have created a work-around, by mapping the transportationID twice: once in key-property, and once as a many-to-one. (instead of one key-many-to-one)
