Ed,
thanks for your answer.
I try to reformulate my problem.
I have an ecore file which details a model.
I changed this model, I rename an EAttribute. So I make a new ecore file
matching with this modification.
I used ecore2ecore mapping to be able to load a file built from the old
model in editor built from the new model.
In my file built form the old model, I have an element (JOnAS) which has a
child (ejbContainer).
In the editor built from the old model, I have in 'Properties' view the
element properties when my element is focused.
In the editor built from the new model, these properties are wrong.
Instead the element properties, I have 3 properties 'Any', 'Any Attribute'
and 'Mixed'.
By example, 'Any' property has for value :
ejbContainers=org.eclipse.emf.ecore.xml.type.impl.AnyTypeImpl@3f45a8
(mixed: [], anyAttribute: [name=ejb])
Note that 'name' is a property of 'EJBContainer' element.
Where can this problem come from ?
From the mapping or from the code ?
Thanks
Guillaume

As I though, it's creating an instance of AnyType.

It may well be an issue with the new model itself. For example, it
sounds like an instance of AnyType is a valid value for the feature of
the new model, but I don't understand the structure of your model that
would allow that... Is this model XML Schema-based and has wildcards?

Ed,
Thanks for your answers.
I try with a very simple model.
I create my model ecore (model.ecore) in a new EMF project (called
SimpleModel):
This is the model :
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="simpleModel"
nsURI="http:///test/1.0.0/simpleModel" nsPrefix="simpleModel">
<eClassifiers xsi:type="ecore:EClass" name="Domain">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="domainName"
lowerBound="1"
eType="ecore:EDataType
http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>
I generated 'Model' code, 'Edit' code and 'Editor' code matching with this
ecore file.
Then I created an other EMF project (called SimpleModel2).
In this project, I created an ecore file (model_new.ecore). This ecore
file is the same except for the attribute name ('domainName' changed into
'nom')
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="simpleModel"
nsURI="http:///test/1.0.1/simpleModel" nsPrefix="simpleModel">
<eClassifiers xsi:type="ecore:EClass" name="Domain">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="nom"
lowerBound="1" eType="ecore:EDataType
http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>
I generated the 'Model' code, 'Edit' code and 'Editor' code.
In my SimpleModel2 project, I copy/paste 'model.ecore'.
From this file, I created the ecore2ecore file and mapped all elements
<?xml version="1.0" encoding="UTF-8"?>
<ecore2ecore:Ecore2EcoreMappingRoot xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:ecore2ecore="http://www.eclipse.org/emf/2004/Ecore2Ecore"
topToBottom="true">
<nested>
<nested>
<nested>
<inputs href="model.ecore#//Domain/domainName/@eGenericType"/>
<outputs href="model_new.ecore#//Domain/nom/@eGenericType"/>
</nested>
<inputs href="model.ecore#//Domain/domainName"/>
<outputs href="model_new.ecore#//Domain/nom"/>
</nested>
<inputs href="model.ecore#//Domain"/>
<outputs href="model_new.ecore#//Domain"/>
</nested>
<inputs href="model.ecore#/"/>
<outputs href="model_new.ecore#/"/>
</ecore2ecore:Ecore2EcoreMappingRoot>
Then I created the 'ecore2xml' file :
?xml version="1.0" encoding="UTF-8"?>
<ecore2xml:XMLMap xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:ecore2xml="http://www.eclipse.org/emf/2005/Ecore2XML">
<ecoreToXMLInfo>
<key xsi:type="ecore:EPackage" href="model_new.ecore#/"/>
<value name="simpleModel"
targetNamespace="http:///test/1.0.0/simpleModel"/>
</ecoreToXMLInfo>
<ecoreToXMLInfo>
<key xsi:type="ecore:EClass" href="model_new.ecore#//Domain"/>
<value name="Domain" targetNamespace="http:///test/1.0.0/simpleModel"/>
</ecoreToXMLInfo>
<ecoreToXMLInfo>
<key xsi:type="ecore:EAttribute" href="model_new.ecore#//Domain/nom"/>
<value name="domainName"/>
</ecoreToXMLInfo>
</ecore2xml:XMLMap>
Then I added an 'org.eclipse.emf.ecore.extension_parser' :
<extension
point="org.eclipse.emf.ecore.extension_parser">
<parser
class="simpleModel.impl.ModelResourceFactoryImpl"
type="simplemodel">
</parser>
</extension>
'ModelResourceFactoryImpl' extends 'XMIResourceFactoryImp' and is written
from the recipe :
http://wiki.eclipse.org/EMF/Recipes#XMI.2FXML_Serialization_ Recipes
I created a file with the 'old' application and I put a name for
'domainName' attribute.
When I load this file in the 'new' application, 'Domain' element has 3
properties 'Any', 'AnyAttribute' and 'Mixed'.
'AnyAttribute' has for value : "domainName=nomDuDomaine" ('nomDuDomaine'
is the name that I put as value in 'old' application).
And 'Domain' has a child : "domainName='nomDuDomaine'"
When I click on this child, in 'Properties' View, I have a property
'Value' and an associated value 'nomDuDomaine'.
I would like have one element : 'Domain'. And when I click on this
element, I would like have in 'Properties' View a property 'nom' (the new
name of this attribute) and a value 'nomDuDomaine'.
Is there something that I do not (or wrong) ?
Thanks
Guillaume

Guillaume,
Could you export the projects involved to an archive (zip or jar) so
that I could import them and reproduce your problem? I'm traveling
today, so I won't be able to look at them until tomorrow.
