如何使用EXT5组合框与数据绑定 [英] How to use Ext5 combobox with data bindings

问题描述

我想用它从数据绑定也是可能的选项从接收数据的同店结合的preselected值的组合框。
该面板项目的配置是这样的：

I want to use a combobox which receives the preselected value from a data binding and also the possible options from a data binding of the same store. The panel items configuration looks like this:

{
    xtype: 'combobox',
    name: 'language_default',
    fieldLabel: 'Default Language',
    multiSelect: false,
    displayField: 'title',
    valueField: 'language_id',
    queryMode: 'local',
    bind: {
        value: '{database.language_default}',
        store: '{database.languages}'
    }
}

如果我用这个配置，组合框的存储是无效的，unuseable。

If I use this configuration, the store of the combobox is invalid and unuseable.

是否有可能为绑定的选择的选项的和也可用选项的的组合框

Is it possible to bind the selected option and also the available options of a combobox?

    fieldLabel: 'Default Language',
    multiSelect: false,
    displayField: 'title',
    valueField: 'language_id',
    queryMode: 'local',
    bind: {
        value: '{database.language_id}',

    }
}
