Cannot get Instances of Applied Stereotypes [message #1753184]

Hello everyone,

I've an problem with getting instances of UML sereotype applications.

I think I've some problem with the registration of the generated EMF code but I am not able to figure out where the problem is.

In advance I am executing everything in the Eclipse context.

My problem is that a call to Element.getStereotypeApplications() only returns a List of DynamicEObjectImpl instances instead of instances of the according EClasses. However, every DynamicEObjectImpl represents the correct EClass and has somehow also a List with the right values for EAttributes.

Ok, what have I done:

I defined a UML profile and for use in Papyrus I created the following two entries in my plugin.xml:

<extension point="org.eclipse.papyrus.uml.extensionpoints.UMLProfile">
  <profile
    iconpath="icons/Logo16x16.png"
    name="UMLsec.Variability" 
    path="pathmap://UMLsec/Variability.uml">
  </profile>
</extension>

<extension point="org.eclipse.emf.ecore.uri_mapping">
  <mapping 
    source="pathmap://UMLsec/Variability.uml"
    target="platform:/plugin/carisma.profile.umlsec.variability/profile/variability.profile.uml">
  </mapping>
</extension>

And inside of Papyrus everything is working fine.

However, I have the problem described above at the point where I am processing the created models.

Until now I tried to register the model at the following extension points but it made no differences:

org.eclipse.uml2.uml.dynamic_package
org.eclipse.uml2.uml.generated_package

If I register a genmodel created from the profile under the same URI at org.eclipse.emf.ecore.generated_package, I get a collision and a call to Element.getStereotypeApplications() or Element.getAppliedStereotypes() returns an empty List.

Therefore, I tried also to register the genmodel with an URI containing a postfix. But this only resolves the collision but makes no difference for my main problem.

I hope I din't forget to mention anything important. Hopefully, you are able to help me.

Thank you very much

Sven

Hello

It seems that you are trying to use a statically generated profile.

Usually the problem is the 'location' property in the extension point 'org.eclipse.uml2.uml.generated_package' that needs to be the URI of the profile element within the profile file (not the URI of the profile file itself)

There is a very useful step-by-step tutorial at http://nyssen.blogspot.fr/2009/09/defining-static-profiles-with-eclipse.html that details this

that shows all the registrations that you need to do
