【 摘 要 】

Following ideas used by Drewnowski and Wilansky we prove that if $I$is an infinite dimensional and infinite codimensional closed ideal in a complete metrizable locallysolid Riesz space and $I$ does not contain any order copy of $mathbb R^{mathbb N}$ then there exists aclosed, separable, discrete Riesz subspace $G$ such that the topology induced on $G$ is Lebesgue, $I cap G ={0}$, and $I + G$ is not closed.
