I need to access to a collection attribute when my validation system intercepts an entity insert/update.
I mean, my model defines A class with a set of B elements.

Hello,

For example, I would like to find all persons that have id 1 or 2 in a database.
The problem is that I cannot do: from Person person where id in elements(:ids) because elements expects an identifier (like person.childIds for example...
I need to write a invoice generating software in ColdFusion 9 using ORM (Hibernate).
One of the requirements is that the invoice number must be sequential without gap, which means no invoice number can be skipped.
The database identity value (i.e. generator="native") does not work as it skips a number if transaction failed to commit.

I would like to perform @Range based hibernate validation checks (org.hibernate.validator.RangeValidator) in my JPA entity code. But it seems to modify the generated SQL with this checks which I would like to avoid. (i.e In the range check, I have the current year as the @Range max value which is bound to change every year).
Hence, I ha...
I am using Hibernate as my JPA provider with it connecting to a Progress database. When a NaN value is persisted it is causing lots of problems - it prevents the row from being read in certain circumstances. Is there a way to hook in to the standard double type persistence to convert NaN (and probably + and - infinity) to a different val...

Criteria association = myCriteria.getAssociation("wax");
if(association == null) association = myCriteri...
