Stereoytpes are not applied after serialization! [message #530318]

Hi all,

i've a problem in applying stereotypes programmatically. At first, i
must say that stereotypes being applied via the "UML Editor" (Element ->
Apply Stereotype) works as expected. That's why i'm pretty sure that the
profile itself is implemented correctly. The profile is realized as a
static profile.

What is the problem:
I try to apply a profile and its stereotype programmatically during a
transformation (handwritten in plain java). Although i'm able to load
and apply the profile as well as the stereotypes, only the applied
profile remains after saving the model. Even the XMI doesn't contain
these additional stereotype entries. But only after serialization! If i
ask (at the end of the transformation) for the profile and the specific
stereotypes, everything is accessbile and present. After serialization,
only the applied profile remains.

Here is the snippet, how the profile is applied by me (don't care for
the prefixes and the uri's. They are correct).

ResourceSet set = new ResourceSetImpl();

final Model model = UMLFactory.eINSTANCE.createModel();
model.setName("Test");

final Profile prof =
(Profile)set.getResource(URI.createURI("platform:plugin/staticProfile/model/my.profile.uml "),
true).getContents().get(0);
model.applyProfile(prof);

org.eclipse.uml2.uml.Class clazz = model.createOwnedClass("TestClass",
false);
final Stereotype s = clazz.getApplicableStereotype("my::Extension");
clazz.applyStereotype(s);

final Resource r = UMLResource.Factory.INSTANCE.createResource(uri);
r.getContents().add(model);
try {
r.save(null);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

I really didn't understand the problem... what am i doing wrong?

Thanks in advance
Timothy

Hi, Timothy,

You need to add the root package ('model') to the resource before you do
anything else. Whenever you apply a stereotype to an element, the UML
API tries to find a resource to which it can add the stereotype
instance. Your element needs to be attached to a resource for this to
work. Otherwise, the stereotype instance ends up floating free.

Cheers,

Christian
