[news.eclipse.modeling.m2m] [QVTO] Problems with resolve and update

[stenzel@xxxxxxxxxxxxxxxxxxxxxxxxxx (Kurt Stenzel)]

Hi,

I seem to 'loose' elements if I modify them after I retrieved them with 
resolve.
In the following program I would expect that mp.packagedElement contains a 
class, but that is not the case.

Is this a bug or a feature?

Thanks for any help,

Kurt

modeltype UML uses 'http://www.eclipse.org/uml2/2.1.0/UML';

transformation updateTest();

mapping main() {
init {
	this.runTest();
}}

query OclAny::runTest() : OclVoid {
	var o := object UML::Class { name := 'myClass'; };
	var p := object UML::Package { packagedElement += o; };
	p.map copyPackage();
	o.map copyClass();
	var mp := p.updatePackage();
	o.name := 'yourClass';
	log('package', mp.packagedElement.name);
	return null;
}

mapping UML::Package::copyPackage() : Package { }
mapping UML::Class::copyClass() : Class { }

query UML::Package::updatePackage() : Package {
	var x := self.resolveone(Package);
	x.packagedElement := 
self.packagedElement.resolveone(PackageableElement)->asSet();
	return x;
}
