    return ViewRegion(this.io.modal({
        title:   "Select Your Players",
        buttons: [
            { text: "Ok",     css: "btn-sm btn-primary" },
            { text: "Cancel", css: "btn-sm", tag: -1 }
        ]
    })).show("app/player/choosePlayer")
       .then(layer => layer.modalResult.then(result => {
           if (result && result.button.tag != -1) {
               return this.selectedPlayers;
           }
       })).finally(() => this.endContext());
