Ron Gavlin commented on TUSCANY-1812:
-------------------------------------
Frank,
Now that Tuscany is using the SDOPackageRegistryDelegator, don't references
from Tuscany to EMF's ExtendedMetaData.INSTANCE become problematic in general
since it's EPackage registry is different from the SDOPackageRegistry within
the Tuscany HelperContext?
The problem in this case appears to be that the "myResult" global property's
extendedMetaData is not an instance of SDOExtendedMetaDataImpl but rather EMF's
BasicExtendedMetaData. The registry within EMF's BasicExtendedMetaData is the
standard EPackageRegistryImpl which doesn't contain the SEVFactoryImpl
registered types.
I've seen some unusual behavior with the DataTypeImpl.getBaseTypes() using the
SDO 1.0 code and I just noticed that this code uses ExtendedMetaData.INSTANCE
as part of its implementation as well. I'll need to investigate more before I
open a JIRA. However, I suspect these problems might be related.
Am I making sense?
