Problem with GenericGenerator annotation [message #116294]

Hi Martin,

first I want to thank you for the hint with the @Basic annotation.

But now I need help with another annotation.
I like to have my ids generated with the hibernate uuid generator.
So I made an annotation to the property I also marked as id:

<eStructuralFeatures xsi:type="ecore:EAttribute" name="logicKey"
eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"
iD="true">
<eAnnotations source="teneo.jpa">
<details key="appinfo"
value="@GenericGenerator(name="uuidgen"
strategy="uuid") "/>
</eAnnotations>
</eStructuralFeatures>

During the mapping generation the following error occurs:

org.eclipse.emf.teneo.annotations.parser.AnnotationParserExc eption: The
eclass: HbAnnotatedEAttribute does not have an efeature for
GenericGenerator
at
org.eclipse.emf.teneo.annotations.parser.EAnnotationParserIm porter.processAnnotatedModelElement(EAnnotationParserImporte r.java:130)

The error message says that I have put the annotation at the wrong place,
but where do I have to put it? I've tried the class itself, but an
equivalent error occured.

Can you help me once more?

greetings
Manfred

Hi Manfred,
The GenericGenerator is specified at EPackage level.

I have attached an example from the Teneo testcases.
