James,
I can't really comment on what's wrong in VE. But I can point out to
the folks working on VE that in EMF 2.3 we changed EJavaObject to be
serializable, i.e., we changed EDataType.isSerializable to true for
EJavaObject and we provided support for that directly in EFactoryImpl
via a new method convertToString(Object) which uses java.io.Serializable
to serialize the results to a byte array and then encodes that byte
array has hex. So when this method is called, the instance object must
support java.io.Serializeable. I wouldn't generally expect generated
code to call this EFactoryImpl method except for array types which
otherwise couldn't be serialized without writing specialized code. So
it seems likely that convertViewRectangleToString needs to be
specialized to do something more appropriate. I wonder if this is a new
data type?
