Are you using UUIDs in your diagram and model resources? This is a

Hi Christian
apologies for my ignorance: what are UUIDs? I've actually used the
diagram generated following the GMF tutorial (part I)...
thanks in advance

Hi, Lorenzo,
UUIDs are the (pseudo-)universally unique identifiers generated by EMF when
an XMLResourceImpl implements useUUIDs() to return true. See
EcoreUtil::generateUUID() for details.

Christian,
I just overrode the useUUIDs() to return true, ran my EMF editor and
created a new root object. But when the editor tried to open the new
resource file it complains about the "id" feature with a
FeatureNotFoundException: Feature 'id' not found. The 'id' feature
looks like the UUID. What else do I need to do?

Hi, john,
I think you also need useIDs() to return true, otherwise the resource will
look in each EClass for an EAttribute that has isID set.

Christian,
I have now overridden both useUUIDs() and useIDs() to return true, and
got the same behavior. All of the objects in the resource file have an
'id' attribute that is set to a (psuedo-)UUID.
When the EMF editor tries to load the resource, I get the exception:
FeatureNotFoundException: Feature 'id' not found.
for every object in the resource.

Hi John,
Actually, you don't need to override useIDs(), since the XMLResourceImpl
implementation already returns true if useUUIDs() does.
There is, however, one additional step required to make the loader
recognize the extrinsic id attribute. This happens by default in
XMIResourceImpl, which is where such IDs are normally used. But, with
the XMLResourceImpl, you need to specify it via the XMLMap option.
This createResource() implementation, which you could put in a custom
Resource.Factory, should be sufficient to create an UUID-enabled
XMLResourceImpl:
public Resource createResource(URI uri)
{
XMLResource result = new XMLResourceImpl(uri)
{
protected boolean useUUIDs()
{
return true;
}
};
XMLResource.XMLMap map = new XMLMapImpl();
map.setIDAttributeName("id");
result.getDefaultLoadOptions().put(XMLResource.OPTION_XML_MA P, map);
return result;
}
Cheers,
Dave

I still haven't tried this solution, but shouldn't this be the default
at least when using GMF generated editors? I mean it's quite natural to
expect copy and paste to work, isn't it?

I believe that GMF does define a resource impl that does this. But of
course you have to be sure you're using that too...

It's not surprising considering that the GMF resource has UUIDs enabled.
