Consistency of ``the ideal of null restricted to some $A$ is $\kappa$--complete not $\kappa^+$--complete, $\kappa$ weakly inaccessible and ${\rm cov}({\rm meagre})=\aleph_1$''

by Shelah. [Sh:E52]

In this note we give an answer to the following question of Grinblat (Moti Gitik asked about it): Is it consistent that for some set X, cov (NULL restriction X)= lambda is a weakly inaccessible cardinal (so X not null of course) while cov (meagre) is small, say it is aleph_1 .
