Hi all,

When i save my model elements releations saved with Sequence Numbers like;

end1Entity="#//@ownedEntityModel/@entities.0"

but on diagram when i switch my models with drag and drop my relation broken cause of Sequence Numbers. My releation always shows 0. element on ownedEntityModel.

so i need to save my model as qualified name. How can i do this ? There is an proper save option ?

Regards

Serhat,

I've been away on vacation...

If an entity has an attribute (or combination of attributes) that make
it unique within the "entities" containment reference you can specify
that attribute (those attributes) as the eKeys of that containment
reference to produce the fragment segment @enties[key='value'] instead
and that will be resilient to reordering changes. Alternatively you
could have a look at how EModelElementImpl specializes the fragment
segments for Ecore models via
org.eclipse.emf.ecore.impl.EModelElementImpl.eURIFragmentSegment(EStructuralFeature,
EObject) and
org.eclipse.emf.ecore.impl.EModelElementImpl.eObjectForURIFragmentSegment(String).

Hi Ed,

I try using UUIDs. But i think there is a problem with this.

When i extend XMIResource and use UUID; some elements have xmi.id but someone not have

like;

<?xml version="1.0" encoding="UTF-8"?>
<content:ContentModel xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:content="http://www.mdd4cca.com/msf/content/Content" xmi:id="_oPDHIJTBEeO-OoAj4bvJwg">
  <ownedEntityModel name="EntityModel">
    <entities name="E1"/>
  </ownedEntityModel>
</content:ContentModel>

Do you know this problem?

I thik, if i can solve this, my problems are solved automatically.

Regards

Might it be the case that you've defined the "name" EAttribute of each
of those two things to have isID true? In
org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.attachedHelper(EObject)
you can see that if an object has an intrinsic ID it won't be assigned
an extrinsic one.

Likely just change your model not to specify intrinsic IDs.

Have a look at what's happening in
org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl.attachedHelper(EObject).
That should be called for each object attached to the resource (i.e.,
for each object contained by the resource). It should assign an ID.
