Answer 1

You can do something like this

in your js put this code

    $(window).load(function () {
        $(document).delegate(".checkall", "click", function(event) {
              $(this).closest("table").find(':checkbox').attr('checked', this.checked);
        });
    });

b.t.w instead of storing in map you can add attribute to your iterated item like this: instead of value="#{SessionsController.selectedIds[item.aSessionID]}" something like this value="#{item.selected}"

and later on you can iterate over them in the server side and add to list that will be sent to you r delete method...
