Your fix is a bit strange, because not all instances
of a link want
to be embedded. This will certainly lead to problems as soon as the
renderer takes care about this new property. It is probably better to
use false as a default instance, but then it will break the environment.
So if you really don't want to drop your existing model instances and
migrate to the latest version I suggest to do something along the lines:
SW2Link allSubInstancesDo: [ :e |
e instVarNamed: 'embedded' put: false ].
SW2SeasideFrame initializeEnvironment.
Thank you
