We have to derive NodeInstanceMetaObject from QQmlVMEMetaObject to support e. g. alias properties. The QmlEngine uses QQmlVMEMetaObject to resolve alias properties. Also we have to invalidate/recreate the QmlPropertyCache if we add dynamic properties. Change-Id: Id52dd8b380eadeb6f74b5171168f2f70c16be118 Reviewed-by: Thomas Hartmann <Thomas.Hartmann@digia.com>
