Multi-filed is not working after upgrade to AEM 6.4
Dear All,
Dear All,
We have developed the multi field in CQ 5.6 and it is working fine in 5.6 . After migration to 6.4 it is not working.
Also ion developer tools I am getting the below error when I am clicking in Add Item 
sign.
widgets.js:112872 Uncaught TypeError: Cannot read property 'toString' of undefined

1) In 5.6 When we click on Add Item , it is coming fine , as shown below.
Below is the dialog and the multi field value is created by using JavaScript , as shown below.
var sunitaSiteClientLib = sunitaSiteClientLib || {};
if(typeof CQ !== 'undefined')
{
sunitaSiteClientLib.MultiFieldPanel = CQ.Ext.extend(CQ.Ext.Panel, {
panelValue: '',
onstructor: function(config){
config = config || {};
sunitaSiteClientLib.MultiFieldPanel.superclass.constructor.call(this, config);
},
initComponent: function () {
sunitaSiteClientLib.MultiFieldPanel.superclass.initComponent.call(this);
this.panelValue = new CQ.Ext.form.Hidden({
name: this.name
});
this.add(this.panelValue);
var dialog = this.findParentByType('dialog');
dialog.on('beforesubmit', function(){
var value = this.getValue();
if(value){
this.panelValue.setValue(value);
}
},this);
},
getValue: function () {
var pData = {};
this.items.each(function(i){
if(i.xtype === "label" || i.xtype === "hidden" || !i.hasOwnProperty("dName")){
return;
}
pData[i.dName] = i.getValue();
});
return $.isEmptyObject(pData) ? "" : JSON.stringify(pData);
},
setValue: function (value) {
this.panelValue.setValue(value);
var pData = JSON.parse(value);
this.items.each(function(i){
if(i.xtype === "label" || i.xtype === "hidden" || !i.hasOwnProperty("dName")){
return;
}
if(!pData[i.dName]){
return;
}
i.setValue(pData[i.dName]);
});
},
validate: function(){
return true;
},
getName: function(){
return this.name;
}
});
CQ.Ext.reg("sunitamultifieldpanel", sunitaSiteClientLib.MultiFieldPanel);
}
2) In 6.4 , When we click on Add Item , it is not coming anything.
