| Mapping eType of reference to eType of attribute [message #1001891] |

Hi,
I define an ecore model with Java interfaces:
import java.net.InetAddress;
/**
* @model
*/
public interface net {
/**
* @model dataType="java.net.InetAddress"
*/
InetAddress getAddress();
}
and
import java.net.InetAddress;
import java.util.List;
/**
* @model
*/
public interface nic {
/**
* @model containment="true" required="false" type="java.net.InetAddress"
*/
List<InetAddress> getAddresses();
}
Now, I would expect that ecore uses the same eType for the attribute net.address and the reference nic.addresses. However, it uses two different eTypes: InetAddress for the attribute and InetAddress_1 for the reference.
How can I enforce that the same eType is used? And why is that happening anyways?
I'm using Eclispe Juno.
Thanks,
Martin

Yes, but as I said, there is little in the way of feedback on what's
wrong with your @model annotations. In your example, not a single one
of the attributes you've specified was sensible in that location.

Have a look at the generated XyzPackage implementation's @model
annotations to see what data types you've ended up with. Once they're
their and they're marked @model, you have to delete them to get rid of them.

What does it look like now?
