Hi, I'm quite new to EMF world but it sounds (and it is) amazing. I'm working on the first project for a customer using EMF. I'm stuck with this problem:

I'm using EMF with Teneo/Hibernate for persisting my model into a database. I can show my model quite well using the generated (with some minor changes) content provider on a treeviewer. So far so good. I need to find some objects in the model using (is it the best way?) HQL query. For example I need to find aCar "2" in this model:

- Car Manufacturer "1"
- Car Seller "1"
- aCar "1"
- aCar "2"
- Car Seller "2"
- aCar "A"

Using HQL it is quite simple to find the car. The problem is that I need to show (on the treeviewer) the entire structure of the parents of the car giving as input the car itself. Ex:

- Car Manufacturer "1"
- Car Seller "1"
- aCar "2"

Is it possible?

Sorry for my poor English and really thank you! Francesco.
