It looks like either a regression in ObjectStateFormatter or an issue with CollectionConverter.
2.4.3 has some changes in the former which introduced proper usage of type converters. It's hard to
tell which of the above is true without getting a test case or access to your application so that I
can reproduce the bug locally. Please file a bug and include a test case (or provide source for
your application if you can). If you can't share your app's code publically and are unable to come
up with a test case, please contact me privately at mhabersack at novell.com and we'll work something
out.
