Sorry for that.
One possible reason for error is I slip in last build dependency from dart-sdk path.
It corrected now (I've just commited build with unittest returned to third_party directory).
Another possibility - tests are assuming mongod running in default configuration (127:0:0:1 27017)
If errors do not dissappear in this build - would you please insert stacktrace of error?
address = new Address(); tagged as error in Dart editor is actually fresh bug in Dart editor I believe.
There is bug http://code.google.com/p/dart/issues/detail?id=3252 filed on similar occasion.
ObjectoryWebSocketImpl was proof of concept which currently seems to me led to nowhere. I've commented it out project.
All stuff related to Objectory is really new and in flux now.
