I have found that a MaClassDefinition instance for one of my domain class still refers to an old definition.
I discover this when updating a readstrategy with an instance variable in the newest class definition but not in the older one (and not in the one defined by the MaClassDefinition instance)
I try to remove the instances of my domain. Close and restart the session. But still I got the oldest definition and obviously the readstrategy definition is causing error.
