How to sync combobox and textfield value. i.e how to load different values from store on textfield,while I am changing values on combobox - model-view-controller

Question

I am new to EXTjs(and to Stackoverflow as well). I was struggling with this issue and at last decided to ask for help.My question is " How to sync combobox and textfield values. i.e how to load different values from 'store' on textfield,while I am changing values on combobox? " My problem is that while I load values on combobox and I select them my textfield stays empty all the time. I tried "Ext.getCmp().setValue();" it works fine with this ,but I think it is not the best option if I'd have 100 textfields. I want combobox and textfield to be synched with store somehow. Any help is appreciated. Situation in pictures are in links below :

And my code :
My app.js :
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'work',
appFolder: 'app',
controllers: ['Work'],
launch: function() {
Ext.create('Ext.container.Viewport', {
//layout: 'fit',
items: [{
xtype: 'rightpanel' // gets it from view class
}
]
});
}
});
My view RightPanel :
Ext.define('work.view.works.RightPanel', {
extend: 'Ext.panel.Panel',
ALIAS: 'widget.rightpanel',
width: 300,
title: 'Building navigation',
animCollapse: true,
collapsible: true,
split: true,
minSize: 400,
maxSize: 400,
margins: '0 5 0 0',
//activeTab:1, tabPosition:'bottom',
initComponent: function() {
this.items = [{
xtype: 'form',
items: [{
xtype: 'combobox',
fieldLabel: 'BuildingID',
queryMode: 'local',
name: 'Bid',
displayField: 'Bid',
valueField: 'Bid',
id: 'Bid',
MODE: 'remote',
store: 'Work'
}, {
xtype: 'textfield',
fieldLabel: 'Address',
name: 'Address',
displayField: 'Address',
valueField: 'Address',
id: 'Address',
store: 'Work'
}]
}];
this.columns = [{
header: 'ID',
dataIndex: 'Bid',
flex: 1
}, {
header: 'Texts',
dataIndex: 'Address',
flex: 1
}];
this.callParent(arguments);
}
});
My store :
Ext.define('work.store.Work', {
extend: 'Ext.data.Store',
model: 'work.model.Work',
storeId: 'workstore',
id: 'workstore',
autoLoad: true,
proxy: {
type: 'ajax',
limitParam: undefined,
startParam: undefined,
paramName: undefined,
pageParam: undefined,
noCache: false,
api: {
read: 'data/showWork.php' // just a .php file that reads values from database and shows them on combobox
},
reader: {
type: 'json',
root: 'data',
successProperty: 'success'
},
writer: {
type: 'json',
root: 'data',
encode: true
}
}
});
My Model class :
Ext.define('work.model.Work', {
extend: 'Ext.data.Model',
//idProperty: 'WorkID',
fields: [{
name: 'Bid',
type: 'int'
}, 'Address']
});
My Controller :
Ext.define('work.controller.Work', {
extend: 'Ext.app.Controller',
stores: ['Work'],
models: ['Work'],
views: [
'works.RightPanel' // name comes from view class
],
init: function() {
console.log('Done');
this.control({
'viewport > rightpanel': {
render: this.test
},
'rightpanel combobox[id=Bid]': {
select: this.change
}
});
},
change: function(buttons) {
var values = this.getStore('Work').collect('Address', 'Address', false);
var win = buttons.up('rightpanel'); // gets the needed widget
var form = win.down('combobox'); // gets the needed form
var value = form.getValue(); // gets the value
console.log("value " + value);
}
});

You want to watch for a change on the combobox, and then action a change based off its new value.
this.items = [{
xtype: 'form',
items: [{
xtype: 'combobox',
fieldLabel: 'BuildingID',
queryMode: 'local',
name: 'Bid',
displayField: 'Bid',
valueField: 'Bid',
id: 'Bid',
mode: 'remote',
store: 'Work'
listeners::{
change:function(cbx, newVal,oldVal,e){
var record = cbx.getStore().find("Bid",newVal); // theres prolly a better way to find this, such as to find the active record of the cbx
Ext.getCmp('Address').setValue(record.getValue("Address"))
}
}
},{
xtype: 'textfield',
fieldLabel: 'Address',
name: 'Address',
displayField: 'Address',
valueField: 'Address',
id: 'Address',
store: 'Work'
}]
