Hi,

I have a problem with bi-directional references:

I have 2 classes:
Company
Contact

A Company can have multiple contacts.
A Contact has 0..1 company.

I have a specific file structure
- Quote
- Description
- Contacts
- Contact 1
- Contact 2
- Companies
- Company 1

Problem in EMF Forms: Location of new entries

When I edit the contact entry, on the company field, if I click on "Create and link a new Company", the new Company object is created as a new root object.

I absolutely don't want that, the company has to be created in
Quote > Description > Companies

The same when I edit a company, if I click to create a new Contact, it is created at the root level as well. I want to keep my structure.

another problem: I even cannot remove those unwanted Contact and Company root entries.

Jim

Hi Jim,
you must provide your own ReferenceService as you can then change the default behavior where new elements are added to.
Take a look at the DefaultReferenceService and the DefaultReferenceServiceFactory.
In short the DefaultReferenceServiceFactory is an OSGi Service which tells EMFForms that there is a ReferenceService and how it behaves. It allows EMFForms to instantiate the ReferenceService when needed.
The DefaultReferenceService is an implementation of the ReferenceService which lets EMF decide where an Element is added to the containment hierarchy.

Cheers,
Eugen
