return this.getObject().then(obj => {
            this.ciceroContext.ciceroClipboard = obj;
            const label = Models.typePlusTitle(obj);
            return this.returnResult('', Usermessages.clipboardContents(label));
        });
    }

private show(): Promise {
        if (this.ciceroContext.ciceroClipboard) {
            const label = Models.typePlusTitle(this.ciceroContext.ciceroClipboard);
            return this.returnResult('', Usermessages.clipboardContents(label));
        } else {

            return this.returnResult('', Usermessages.clipboardEmpty);
        }
