Hi,

My question regards multiple selection. In the documentation (Databinding> Collection and Selections > Multiple Selections) it mentions that to access the selected items we should bind selectedItems to a property whose type is Set. This works if the components model type is ListModelList, but I use a ListModelMap<key, obj="">.

If I implement

Set<Obj> selectedObjs = new HashSet<Obj>();

When trying to access the selectedItems in the view model I get an error: Obj cannot be cast to java.util.Map$Entry because i guess that there is incompatibitlity between sublasses of Set (like HashSet) and ListModelMap. Can you advise a solution to this, thanks
