Hi, thanks for clarification, I wasn't aware that this is according to specs, my bad.

The main reasons is that I don't want to "pollute" my entities with a (or maybe more) additional constructors that are only required for a query. The Result transformer is exactly the place where I want to assemble the object based on maybe various conditions.

Moreover, I could imagine that during criteria assembly time, it might be not 100% certain what the resulting object looks like, so IMHO it is a good possibility to defer the decision to the latest step as possible.

Using Object[] works fine, thanks for the hint!
