Compactness of Kőnig-property

A hypergraph H=(V,E) has the Kőnig-property if there is a set DE of pairwise disjoint hyperedges such that there is a vertex cover consists of one vertex from each hyperedge in D. (Using this terminology Kőnig's theorem says that every finite bipartite graph has the Kőnig-property). R. Aharoni and N. Bowler formulated independently the following conjecture. If H=(V,E) is a hypergraph such that all of its hyperedges are finite and for all finite EE the hypergraph (V,E) has the Kőnig-property, then H has the Kőnig-property as well.
