Oh, no possibility to upload a patch-file!

So here are my code changes in Helper.ext and Helper.java:

Helper.ext:
>>>
String fqName (uml::Type type, String prefix) :
JAVA org.fornax.cartridges.uml2.javabasic.Helper.getFqName(org.eclipse.uml2.uml.Type, java.lang.String);

String fqName (uml::Type type) :
JAVA org.fornax.cartridges.uml2.javabasic.Helper.getFqName(org.eclipse.uml2.uml.Type);
<<<
