The call to connectionRepository().getAllDescriptor() returns a deep copy of all of
the connection descriptors, so any changes you make to those descriptors will not be
reflected in the global repository. To do that, you'll have to remove the descriptor
from the global repository and re-add it. Something like after you call
changeDescriptor method should work:
ConnectionRepository connRepo =
MetadataManager.getInstance().connectionRepository();
connRepo.removeDescriptor(desc);
connRepo.addDescriptor(desc);
