I've a problem with EMF and ExtendedMetaData.
I tried with a really small ecore model where 'A' contains 'B's through a reference 'attr'. I change the name of this reference to 'attribute' using an ExtendedMetaData anotation.
<ecore:EPackage xmi:version="2.0" xmlns:xmi="htxp://www.omg.org/XMI" xmlns:xsi="htxp://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="htxp://www.eclipse.org/emf/2002/Ecore" name="a" nsURI="a" nsPrefix="a">
<eAnnotations source="htxp:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="qualified" value="false"/>
</eAnnotations>
<eClassifiers xsi:type="ecore:EClass" name="A">
<eStructuralFeatures xsi:type="ecore:EReference" name="attr" upperBound="-1" eType="#//B"
containment="true">
<eAnnotations source="htxp:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="name" value="attribute"/>
</eAnnotations>
</eStructuralFeatures>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="B">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="x" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>
From this I generate a genmodel and then generat code (model, edit and editor) and start the runtime workbench.
I create a model using the model wizard for this ecore model and it seems to be ok. The reference chnage from 'attr' to 'attribute'.
<?xml version="1.0" encoding="UTF-8"?>
<A xmlns:xsi="htxp://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="a">
<attribute x="x"/>
</A>
When I close it and and try to open it again with the same editor I created it in I get an error (attached as image also, as is the stack trace):
Problem encountered in file "platform/resource/a/My.a"
FeatureNotFoundExeption: Feature 'attribute' not found (platform/resource/a/My.a,3,21)
If I open the model and change the name of the references backto 'attr' (as defined if the ExtendedMetaData wasn't set) it works, ie. it can be loaded.
Can someone explain this behavior to me?
I use:
- Kepler Release Build id: 20130207-1142
- EMF 2.9.0
PS. Due to this "You can only use links to eclipse.org sites while you have fewer than 5 messages." I have to use htxp instated of http. DS

Patrik,
You're sure this resource factory getting used? You could set a
breakpoint in
org.eclipse.emf.ecore.xmi.impl.XMLHelperImpl.getFeature(EClass, String,
String, boolean) to see why it's failing. You can make the breakpoint
conditional on name being the name of the feature in question...
