If ComboBox's valueField is int type field, It will not work properly.

[manlsea]

var themeStore = Ext.create('Ext.data.Store', {
fields: ['value', 'name'],
data: [
{ value: 0, name: "default" },
{ value: 1, name: "access" },
{ value: 2, name: "gray" },
{ value: 3, name: "scoped" }]
});

var languageStore = Ext.create('Ext.data.Store', {
fields: ['value', 'name'],
data: [
{ value: "en", name: "English" },
{ value: "zh", name: "Chinese"}]
});

items: [{
xtype: 'combobox',
name: 'Language',
queryMode: 'local',
maxLength: 16,
fieldLabel: 'Language',
displayField: 'name',
valueField: 'value',
//value: 'en',
editable: false,
store: languageStore
}, {
xtype: 'combobox',
name: 'Theme',
queryMode: 'local',
maxLength: 16,
fieldLabel: 'Theme',
displayField: 'name',
valueField: 'value',
value: 0,
editable: false,
store: themeStore
}]

form.findField('Language').select('en');

form.findField('Theme').select(0);

As below

You shouldn't need to use the select method. This works as expected:

var themeStore = Ext.create('Ext.data.Store', {
    fields: ['value', 'name'],
    data: [
        { value: 0, name: "default" },
        { value: 1, name: "access" },
        { value: 2, name: "gray" },
        { value: 3, name: "scoped" }]
});

var languageStore = Ext.create('Ext.data.Store', {
    fields: ['value', 'name'],
    data: [
        { value: "en", name: "English" },
        { value: "zh", name: "Chinese"}]
});

new Ext.panel.Panel({
    renderTo : document.body,
    width    : 400,
    height   : 400,
    title    : 'Test',
    items    : [
        {
            xtype : 'combobox',
            name: 'Language',
            queryMode: 'local',
            maxLength: 16,
            fieldLabel: 'Language',
            displayField: 'name',
            valueField: 'value',
            value: 'en',
            editable: false,
            store: languageStore
        },
        {
            xtype: 'combobox',
            name: 'Theme',
            queryMode: 'local',
            maxLength: 16,
            fieldLabel: 'Theme',
            displayField: 'name',
            valueField: 'value',
            value: 0,
            editable: false,
            store: themeStore
        }
    ]
});

I'm sure used the select method.

form.findField('Language').select('en');

form.findField('Theme').select(0);

But, I can notget the righteffect by select(0).
