ClassCastException: org.eclipse.uml2.impl.GeneralizationImpl with EMF-UML2 model
--------------------------------------------------------------------------------
Key: UMLMETA-83
URL: http://jira.andromda.org/browse/UMLMETA-83
Project: UML Metafacades
Type: Bug
Environment: Using 3.3-SNAPSHOT but involved code is unchanged since 3.2 final.
Reporter: Jerome Leclercq
Assigned to: Wouter Zoons
Happens when using meta-cartridge with a EMF/UML2 metamodel :
java.lang.ClassCastException: org.eclipse.uml2.impl.GeneralizationImpl
at
org.andromda.metafacades.emf.uml2.ModelElementFacadeLogicImpl.handleGetTaggedValues(ModelElementFacadeLogicImpl.java:599)
at
org.andromda.metafacades.emf.uml2.ModelElementFacadeLogic.getTaggedValues(ModelElementFacadeLogic.java:991)
...
Now let's take a look at the code :
protected java.util.Collection handleGetTaggedValues() {
return UmlUtilities.getTaggedValue((NamedElement)this.metaObject);
}
Which is incorrect, because Generalizations aren't Sub-interfaces of
NamedElement, but Element.
Looking at "UmlUtilities.getTaggedValue(NamedElement)" shows that code that
needs NamedElements are only debug logs.
Correction diffs :
