Hi,

I'm a bit confused with a problem I got, I've some EClass called
Message, MessageGroup and I want to append some
Message entities to my MessageGroup.

When I execute the following code

Message message = getMessageFactory().createMessage();
message.setValue(element.getMessage(locale));
group.getMessages().add(message);

message is correctly added to the MessageGroup but If I open the message
file with a text editor or the emf editor
the message is not saved in the model

What can be the cause ?

Thanks in advance

Alexandre,

Is the MessageGroup.messages reference a containment reference?

Hi Ed,

There is a relation between MessageGroup and Message called messages but
this is not a containment reference.

Alexandre,

The Message instance will need to be contained by some containment
reference or directly in the contents of the resource to be serialized
(and only XMI resources support multiple roots). I.e., if
message.eResource() == null, it can't be serialized.
