Ron Gavlin commented on TUSCANY-1812:
-------------------------------------
Here's more info.
The problem indeed occurs during the invocation of
BasicExtendedMetaData.createEStructuralFeatureExtendedMetaData() which
instantiates the inner class
BasicExtendedMetaData.EStructuralFeatureExtendedMetaDataImpl. This inner class
relies on its outer class to access the registry. In the dynamic SDO case, the
outer class is SDOExtendedMetaDataImpl which contains the correct registry. In
the static SDO case, the outer class is EMF's BasicExtendedMetaData which
contains the incorrect registry. I have pasted the two stack traces below for
comparison. Later on, the getAffiliation() method is invoked which triggers the
problem registry access in the outer class.
In order to fix the static SDO case, should "DocumentRoot" be handled as a
special case? This would avoid going down the EMF-centric DynamicDataObjectImpl
path evident in the stack trace. Or, is another more generic fix appropriate?
Obviously, this is a pressing issue for us. If this is a problem you have time
to address and think you can fix in a timely fashion, then I'll let you take it
from here. Otherwise, if you or one of the other committers could provide me
some direction for fixing the problem, I would appreciate it.
Thanks,
- Ron
