Get the values from more complex form

Webix JS
1

I can’t get all values from the id “queryForm2”
I only get the elements start, end and limit back.
What could be wrong
Kind regards,
Rolf

var queryResult = { view: "form", elements: [
		{ view:"text", value:'',
			id: "queryResult",
			label:"Query-Result",
			disabled:true,
			height:100,
			labelPosition:"top"
		},
		{ view:"button", type:"form", value:"Suchen", click:function(){
			$$("queryResult").setValue(JSON.stringify( $$("queryForm2").getValues()));
			}}
]};

var queryForm = { view:"form", id: "queryForm2", elements:[
	{cols:[
		{width:250, rows :[
          { view:"combo", width:200, label:"System", options:['bc','dt']},
          { view:"combo", label:"Host", options:['Host 1','Host 2']},
			{ view:"text", value:'', label:"Referenz"}
		]},
		{margin:0, paddingX: 10, width: 200, rows:[
			{ view:"checkbox", id:"event0", label:"Emergency", value:1},
			{ view:"checkbox", id:"event1", label:"Alert", value:1},
			{ view:"checkbox", id:"event2", label:"Critical", value:1},
			{ view:"checkbox", id:"event3", label:"Error", value:1},
			{ view:"checkbox", id:"event4", label:"Warning", value:1},
			{ view:"checkbox", id:"event5", label:"Notice", value:0},
			{ view:"checkbox", id:"event6", label:"Info", value:0},
			{ view:"checkbox", id:"event7", label:"Debug", value:0}
		]},
		{ margin:10, rows:[
			{view:"radio", label:"Branch", value:1, 
			options:[{id:1,value:"Live" },{id:2,value:"Test" },{id:3,value:"Alle" }]},
			{ view:"datepicker", label:"Start", name:"start", 
			stringResult:true, format:"%d  %M %Y" },
			{ view:"datepicker", label:"Ende", name:"end", 
			stringResult:true, format:"%d  %M %Y" },
			{ view:"text", label:"Limit", name:"limit", value:"250"}
		]}
    ]}
]}


webix.ui({
    
    rows: [
    	{ view:"label", label: "Query-Form", align:"center"},
    	queryForm,
    	queryResult
    ]
});

all required elements must have ‘name’ attribute to be included in getValues()
