  method Update:

 this.values = JSON.parse(getValue(this.dataView.metadata.objects, "settings", "config", "No items"));
           let items="";
           this.values.forEach(element => {
                items+=element+"\n";
            });
           
$("#q").val(items);

Enumerate:

 public enumerateObjectInstances(options: EnumerateVisualObjectInstancesOptions): VisualObjectInstance[] | VisualObjectInstanceEnumerationObject {
           // return VisualSettings.enumerateObjectInstances(this.settings || VisualSettings.getDefault(), options);
             let objectName = options.objectName;
            let objectEnumeration: VisualObjectInstance[] = [];
         
           

            this.visualHost.persistProperties(<VisualObjectInstancesToPersist>{
                merge: [{
                    objectName: "settings",
                    selector: null,
                    properties: {
                        config: JSON.stringify(this.values) || "{}",
                        show:true
