I'm migrating my projects from oaw4 to oaw5 (MWE + Xpand + Xtext).

in oaw4 I'm using


(long time ago I used the org.openarchitectureware.emf.XmiReader, but switched
to emf.Reader because XMIReader is deprecated)

now in oaw5 I renamed

org.eclipse.mwe.emf.Reader into org.eclipse.emf.mwe.utils.Reader

but now this emf reader has problems to read

* EMF-UML2-XMI exports from MagicDraw

* uml files written by UML2Writer

If I'm using the

(deprecated) org.eclipse.xtend.typesystem.emf.XmiReader

then all works well.

If I make a short test after readinf the model like


then I'm getting 0 using emf Reader under oaw5

and the correct value using XMIReader.

using oaw4 both log correct size: emf reader and XMIReader
talked about this with Karsten Thoms:
problems seem to be a different behaviour if you're using emf + uml2 + profile

my current definitions in my Xpand, Xtend, Xcheck components:

1. EMF MetaModel

2. UML2 MetaModel

3. UML2 Profiles MetaModel

(works using XMIReader in oaw4 and oaw5, works also using emf Reader in oaw4)

Since Xpand / MWE / Xtext 0.7.1 it should work if you only define the profiles
MetaModel in Xpand or Xtend components.

in Karsten's workflow this works

for my workflow this also works (I can remove emf metamodel and uml2 metamodel
from my components)

...but - as before - it only works using XMIReader, not using emf Reader

(My uml2 model is a MagicDraw 16.5 model exported as EMF - UML2 - XMI)

btw: if I define metamodels in components in this order:

1. uml2 profile

2. emf

then I get errors like

Couldn't find operation 'setName(String)' for uml::Property from Xtend

Couldn't find operation 'getAppliedStereotype(String)' for
uml::EnumerationLiteral from generator


after hours and hours of testing I have to say this is really a regression

and at the moment - to work with oaw5 - I have to use the deprecated XMIReader

any ideas ?
or should I open a Bugzilla ?
