Hi, Any idea as to when the fix would be incorporated into hibernate and made available for the users?

> The number of elements that we can put in a "in" expression is limited to a certain amount (1000 for Oracle, for instance). When creating a criteria query, the org.hibernate.criterion.InExpression class should split the expression into several smaller ones.
> Attached is a patch which splits the expression by slices of 500 elements. For example, if we have 1001 elements to put in the "in" expression, the result would be :
> (entity.field in (?, ?, ?...) or entity.field in (?, ?, ?...) or entity.field in (?))
> The surrounding parantheses are useful to avoid problems with other conditions (a "and" condition taking over the one of the "or" conditions).
