Feature 'eAnnotations' not found. [message #1858311]

Hi ,

I am using the Ecore based metamodel of a UML profile, and when I try to access it in XTend I get the error "Feature 'eAnnotations' not found.". Could it be because in the header it is registered
"xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML""
but the Eannotations are referencing 2.0.0?
" <eAnnotations xmi:id="_uZK_NBHVEdu19OChlR9tHg" source="http://www.eclipse.org/uml2/2.0.0/UML">"?

If so, where can I find that version of UML to also register it in Xtend?
I have registered the 3.0.0 version in Xtend.

Thank you in advance!

Hi

Very unlikely. The eAnnotation source string is usually dated from the time of first use and never changed thereafter.

However the use of "xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML"" rather than xmlns:uml="http://www.eclipse.org/uml2/5.0.0/UML" suggests a very old version of UML2 that probably predates the first version of Xtend.

As always, if you don't provide a repro, it can be very hard for replies to be more than guesswork.

My best guess is that Xtend has not called UMLResourcesUtil.init() which is not surprising since Xtend is not a UML supporting tool.
