I am working on backwards compatibility using Ecore2XML files. So far, this is going great.|
However, I now have the following mapping:
* feature1 (derived)
OldFoo <-> NewFoo
OldFoo::feature1 <-> NewFoo::feature2
UNMAPPED <-> NewFoo::feature1
I expected OldFoo::feature1 to be mapped correctly to OldFoo::feature2. Instead, the ExtendedMetaData object tries to map NewFoo::feature1 first. Instead of marking it 'unmapped', a fallback maps it to OldFoo::feature1, based on similarity on containingClass and feature name.
How can I make the ExtendedMetadata execute the above mapping correctly?

Yes, that's a nice way and it lets you do arbitrarily complex things...
