| Facing issue with EMF Enum persistence and loading using WST Translator [message #501689] |

Hi,
I am struggling with a problem which initially looked trivial but aparently is not the case:
My Ecore model contains an EMF enum called Cardinality:
<eClassifiers xsi:type="ecore:EEnum" name="Cardinality">
<eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
<details key="name" value="Cardinality"/>
</eAnnotations>
<eLiterals name="_01" literal="0..1"/>
<eLiterals name="_0N" value="1" literal="0..n"/>
</eClassifiers>
I am using WST Translator to persist and load EMF entities. When I persist the same, it gets persisted by its literal and not name:
<... cardinality="0..1">
Which is the desired way of persisting.
However, when I try to load it, it tries to match the dom attribute value of cardinality "0..1" to the name of the cardinality "_0N" and hence throws the following exception:
aused by: org.eclipse.wst.common.internal.emf.utilities.FeatureValueCo nversionException: IWAE0014E Failed to convert 0..1 to Enumeration.

Can anyone please help me how to fix this issue. I tried replacing the name for the Cardinality enum to "0..n", however, the genmodel gives an error.
Also I dont want to change the generated Java Class for the cardinality.
Thanks a lot,
Best Regards,
Nidhi
